Worm holes( Einstein's rogen bridge)

In last post I have discussed possible way of time travelling today I will discuss a more hypothetical way of time and space travel that is warm holes also known as Einstein's rogen bridge.
General relativity also allows for the possibility for shortcuts through spacetime, known as wormholes, which might be able to bridge distances of a billion light years or more, or different points in time.

Many physicists, including Stephen Hawking, believe wormholes are constantly popping in and out of existence at the quantum scale, far smaller than atoms. The trick would be to capture one, and inflate it to human scales - a feat that would require a huge amount of energy, but which might just be possible, in theory.

Attempts to prove this either way have failed, ultimately because of the incompatibility between general relativity and quantum mechanics.
Freinds there are many sceince fiction movie based on worm holes you have seen

possibility of time travel

Freinds yesterday I talk about time travel today i am going to tell you how time travel can possible there are many thesis from worm holes to general relativity.
Travel to past is only hypothesis but in reality near to impossible becouse of many paradox grandfather paradox is one of them suppose you built a time machine and went to past to meet your grandfather and that day he has to meet your grandmother and stop him for doing that and they never meet so your father didn't born and you also so how you wil you made time machine this is most discussed paradox.
But travel in future quite easy than travel in past. The most important by travel near to speed of light according to einstein theory of relativity flow of time change with speed of light. This is not a just a conjecture or thought experiment – it’s been measured. Using twin atomic clocks (one flown in a jet aircraft, the other stationary on Earth) physicists have shown that a flying clock ticks slower, because of its speed.

In the case of the aircraft, the effect is minuscule. But If you were in a spaceship travelling at 90% of the speed of light, you’d experience time passing about 2.6 times slower than it was back on Earth.

And the closer you get to the speed of light, the more extreme the time-travel.

The highest speeds achieved through any human technology are probably the protons whizzing around the Large Hadron Collider at 99.9999991% of the speed of light. Using special relativity we can calculate one second for the proton is equivalent to 27,777,778 seconds, or about 11 months, for us.

Amazingly, particle physicists have to take this time dilation into account when they are dealing with particles that decay. In the lab, muon particles typically decay in 2.2 microseconds. But fast moving muons, such as those created when cosmic rays strike the upper atmosphere, take 10 times longer to disintegrate.
2. Gravity

The next method is also inspired by Einstein. According to his theory of general relativity, the stronger the gravity you feel, the slower time moves.

As you get closer to the centre of the Earth, for example, the strength of gravity increases. Time runs slower for your feet than your head.

Again, this effect has been measured. In 2010, physicists at the US National Institute of Standards and Technology (NIST) placed two atomic clocks on shelves, one 33 centimetres above the other, and measured the difference in their rate of ticking. The lower one ticked slower because it feels a slightly stronger gravity.

To travel to the far future, all we need is a region of extremely strong gravity, such as a black hole. The closer you get to the event horizon, the slower time moves – but it’s risky business, cross the boundary and you can never escape.

And anyway, the effect is not that strong so it’s probably not worth the trip.

Assuming you had the technology to travel the vast distances to reach a black hole (the nearest is about 3,000 light years away), the time dilation through travelling would be far greater than any time dilation through orbiting the black hole itself
These hypothesis are based on two diffrent theory of eistein. There is another way called Einstein's rogen bridge also known as worm holes. That will i discuss in next blog

Is time travel possible

My today post is not about any description it about a universal question a sceince fiction hypothesis . Wich make every won curious to know about time and time travel. Einstein's Theory of Relativity says that time travel is perfectly possible — if you're going forward. Finding a way to travel backwards requires breaking the speed of light, which so far seems impossible. But now, strange-but-true phenomena such as quantum non-locality, where particles instantly teleport across vast distances, may give us a way to make the dream of traveling back and forth through time a reality. Step into a time machine and rewrite history, bring loved ones back to life, control our destinies. But if we succeed, what are the consequences of such freedom? Will we get trapped in a plethora of paradoxes and multiple universes that will destroy the fabric of the universe?
Freinds this is only questions in next post i will discuss about sceintific way by wich time travel is possible.

What is Dark Energy

In physical cosmology and astronomy, dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe.Dark energy is the most accepted hypothesis to explain the observations since the 1990s indicating that the universe is expanding at an accelerating rate.

Assuming that the standard model of cosmology is correct, the best current measurements indicate that dark energy contributes 68.3% of the total energy in the present-day observable universe. The mass–energy of dark matter and ordinary (baryonic) matter contribute 26.8% and 4.9%, respectively, and other components such as neutrinos and photons contribute a very small amount. The density of dark energy (~ 7 × 10−30 g/cm3) is very low, much less than the density of ordinary matter or dark matter within galaxies. However, it dominates the mass–energy of the universe because it is uniform across space.

Two proposed forms for dark energy are the cosmological constant, representing a constant energy density filling space homogeneously, and scalar fields such as quintessence or moduli, dynamic quantities whose energy density can vary in time and space. Contributions from scalar fields that are constant in space are usually also included in the cosmological constant. The cosmological constant can be formulated to be equivalent to the zero-point radiation of space i.e. the vacuum energy. Scalar fields that change in space can be difficult to distinguish from a cosmological constant because the change may be extremely slow.

what is dark matter

Dark matter is a hypothetical type of matter distinct from baryonic matter (ordinary matter such as protons and neutrons), neutrinos and dark energy. Dark matter has never been directly observed; however, its existence would explain a number of otherwise puzzling astronomical observations.Dark matter has never been directly observed; however, its existence would explain a number of otherwise puzzling astronomical observations. The name refers to the fact that it does not emit or interact with observable electromagnetic radiation, such as light, and is thus invisible to the entire electromagnetic spectrum.

Although dark matter has not been directly observed, its existence and properties are inferred from its gravitational effects such as the motions of baryonic matter, gravitational lensing, its influence on the universe's large-scale structure, on the formation of galaxies, and its effects on the cosmic microwave background.

The standard model of cosmology indicates that the total mass–energy of the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter constitutes 84.5%[note 1] of total mass, while dark energy plus dark matter constitute 95.1% of total mass–energy content.The great majority of ordinary matter in the universe is also unseen. Visible stars and gas inside galaxies and clusters account for less than 10% of the ordinary matter contribution to the mass-energy density of the universe. The most widely accepted hypothesis on the form for dark matter is that it is composed of weakly interacting massive particles (WIMPs) that interact only through gravity and the weak force. The dark matter hypothesis plays a central role in current modeling of cosmic structure formation, galaxy formation and evolution, and on explanations of the anisotropies observed in the cosmic microwave background (CMB). All these lines of evidence suggest that galaxies, galaxy clusters, and the universe as a whole contain far more matter than that which is observable via electromagnetic signals.Many experiments to detect proposed dark matter particles through non-gravitational means are under way; however, no dark matter particle has been conclusively identified.

Although the existence of dark matter is generally accepted by most of the astronomical community, a minority of astronomers,motivated by the lack of conclusive identification of dark matter, or by observations that don't fit the model, argue for various modifications of the standard laws of general relativity, such as MOND, TeVeS, and conformal gravity that attempt to account for the observations without invoking additional matter.

scope in robotics

Guess my this post is for young student engineer researcher and tech enthusiast robotics is a sceince of giving artificial intelligence to machine for making life comfortable easier and faster. In growing modernisation of world we need a machine who can take decision itself . Utilize man in more creative work and give labour work to robots. At border we can save our man's by replacing them with fighter robots
More cleaning is possible by using cleaner robots
A daily work can be improved by personal robots
All hard work that physically man can not can be done by robots
A mind control robot can do work on only your thinking
Technical singularity is possible by modernisation of robotics and more research in it
There are much more scope in robots where  an young utilise his potential and skill.

world first molecular robots

In the future such robots could be used for medical purposes, advanced manufacturing processes and even building molecular factories and assembly lines. The research will be published in Nature on Thursday 21st September.

Professor David Leigh, who led the research at University's School of Chemistry, explains: 'All matter is made up of atoms and these are the basic building blocks that form molecules. Our robot is literally a molecular robot constructed of atoms just like you can build a very simple robot out of Lego bricks. The robot then responds to a series of simple commands that are programmed with chemical inputs by a scientist.

'It is similar to the way robots are used on a car assembly line. Those robots pick up a panel and position it so that it can be riveted in the correct way to build the bodywork of a car. So, just like the robot in the factory, our molecular version can be programmed to position and rivet components in different ways to build different products, just on a much smaller scale at a molecular level.'

Future of robotics and AI

Guess now a days technology is growing minute by minute in every feild every where you see that machines are making your life more suitable but what happen when these machine will replaced by artificial intelligence what happens if you can talk to your house your daily usable things. They work according to your need security increase your life style will enhanced due to rise of internet of things
Means your house daily use thing all will connected to a internet wich is in control of personal. Your bed knows when you have to rise
Your cook robot know when you need tea or coffee
Everything done by AI then think what will happen
In recent history researcher at university of Tokyo create a robot who can copy a human skill can show emotions can b act like teacher can sing a song and most importantly a robot made in Germany can defeat a chess champion this all is initial like a robot develop in USA is able to fight and go to the war. And I hope this will increase day by day and our future will be intelligence so that's it guess if you have any query then comment please

Indian astronomer discovered a supernova river of galaxy

Introduction of gravitational wave

As you all know the news that The Nobel Prize in Physics 2017 was divided, one half awarded to Rainer Weiss, the other half jointly to Barry C. Barish and Kip S. Thorne "for decisive contributions to the LIGO detector and the observation of gravitational waves". Know every one want to know about gravitational wave
So let's know about it. Gravitational waves are ripples in the curvature of spacetime that are generated in certain gravitational interactions and propagate as waves outward from their source at the speed of light. Their possibility was discussed in 1893 by Oliver Heaviside using the analogy between the inverse-square law in gravitation and electricity. In 1905, Henri Poincaré first proposed gravitational waves (ondes gravifiques) emanating from a body and propagating at the speed of light as being required by the Lorentz transformations. Predicted in 1916 by Albert Einstein on the basis of his theory of general relativity, gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation. Newton's law of universal gravitation, part of classical mechanics, does not provide for their existence, since that law is predicated on the assumption that physical interactions propagate at infinite speed—showing one of the ways the methods of classical physics are unable to explain phenomena associated with relativity.

Gravitational-wave astronomy is a branch of observational astronomy that uses gravitational waves to collect observational data about sources of detectable gravitational waves such as binary star systems composed of white dwarfs, neutron stars, and black holes; and events such as supernovae, and the formation of the early universe shortly after the Big Bang.

On February 11, 2016, the LIGO and Virgo Scientific Collaboration announced they had made the first observation of gravitational waves. The observation itself was made on 14 September 2015, using the Advanced LIGO detectors. The gravity waves originated from a pair of merging black holes. After the initial announcement the LIGO instruments detected two more confirmed, and one potential, gravitational wave events In August 2017, the two LIGO instruments, and the Virgo instrument, observed a fourth gravitational wave from merging black holes, and a fifth gravitational wave from binary neutron star merger. Several other gravitational-wave detectors are planned or under construction.
In general  when two neutron stars collide they would produce a gravitational wave, a ripple in the universe-wide fabric of space-time. Four other times that these waves were detected they were the result of merging black holes. This is the first time scientists observed one caused by a neutron star crash.

cybernetics

As technology increasing day by day the integration of machine and human increasing and possibility of more developed future this is all due to new technology called cybernetics
Cybernetics is a transdisciplinary approach for exploring regulatory systems—their structures, constraints, and possibilities. Norbert Wiener defined cybernetics in 1948 as "the scientific study of control and communication in the animal and the machine."In the 21st century, the term is often used in a rather loose way to imply "control of any system using technology." In other words, it is the scientific study of how humans, animals and machines control and communicate with each other.

Cybernetics is applicable when a system being analyzed incorporates a closed signaling loop—originally referred to as a "circular causal" relationship—that is, where action by the system generates some change in its environment and that change is reflected in the system in some manner (feedback) that triggers a system change. Cybernetics is relevant to, for example, mechanical, physical, biological, cognitive, and social systems. The essential goal of the broad field of cybernetics is to understand and define the functions and processes of systems that have goals and that participate in circular, causal chains that move from action to sensing to comparison with desired goal, and again to action. Its focus is how anything (digital, mechanical or biological) processes information, reacts to information, and changes or can be changed to better accomplish the first two tasks.Cybernetics includes the study of feedback, black boxes and derived concepts such as communication and control in living organisms, machines and organizations including self-organization.

Concepts studied by cyberneticists include, but are not limited to: learning, cognition, adaptation, social control, emergence, convergence, communication, efficiency, efficacy, and connectivity. In cybernetics these concepts (otherwise already objects of study in other disciplines such as biology and engineering) are abstracted from the context of the specific organism or device.

The word cybernetics comes from Greek κυβερνητική (cybernēticḗ), meaning "governance", i.e., all that are pertinent to κυβερνάω (cybernáō), the latter meaning "to steer, navigate or govern", hence κυβέρνησις (cybérnēsis), meaning "government", is the government while κυβερνήτης (cybernḗtēs) is the governor or "helmperson" of the "ship". Contemporary cybernetics began as an interdisciplinary study connecting the fields of control systems, electrical network theory, mechanical engineering, logic modeling, evolutionary biology, neuroscience, anthropology, and psychology in the 1940s, often attributed to the Macy Conferences. During the second half of the 20th century cybernetics evolved in ways that distinguish first-order cybernetics (about observed systems) from second-order cybernetics (about observing systems). More recently there is talk about a third-order cybernetics (doing in ways that embraces first and second-order).

Studies in cybernetics provide a means for examining the design and function of any system, including social systems such as business management and organizational learning, including for the purpose of making them more efficient and effective. Fields of study which have influenced or been influenced by cybernetics include game theory, system theory (a mathematical counterpart to cybernetics), perceptual control theory, sociology, psychology (especially neuropsychology, behavioral psychology, cognitive psychology), philosophy, architecture, and organizational theory. System dynamics, originated with applications of electrical engineering control theory to other kinds of simulation models (especially business systems) by Jay Forrester at MIT in the 1950s, is a related field.

How do star die

freinds today I am going to tell you about how really star dei as you all know that any thing in the universe have end. Same is about star. Star dei because they exhaust there nuclear fuel the event of end of star life depend on its mass.  Real massive star use up there hydrogen fuel quickly, but are hot enough to fuse have it elements such as helium and Corbin. Once there is no fuel left, the star collapses and the outer layer explode as a supernova . What is left over after a supernova explosion is a neutron star - the collapsed core of star or if there a sufficient mass, a black hole averaged sized star up to about 1.4 times mass of sun will dei less dramatically . As there hydrogen is used up they swell to became red gaint , fusing helium in there core, before sharing there outer layer after forming a planetary nebula . Star core remain as white dwarf wich cool off over billion years. Tinniest star known as dwarf star( red dwarf) but there nuclear fuel are so slow that they live 100 billion year more then the ege of universe

So guess I think you understand about death of star . If you have any questions then ask me and if any topic you want to know then comment me

Technical singularity

As I discussed in digital immortality that longevity is possible by integrating human and computers or machines in virtual environment of consignees this phenomenon is called technical singularity. It is a broad hypothesis wich open a door of imagination for researcher and scientist for a future where no one dei.
According to this hypothesis, an upgradable intelligent agent (such as a computer running software-based artificial general intelligence) would enter a "runaway reaction" of self-improvement cycles, with each new and more intelligent generation appearing more and more rapidly, causing an intelligence explosion and resulting in a powerful superintelligence that would, qualitatively, far surpass all human intelligence. John von Neumann first used the term "singularity" (c. 1950s), in the context of technological progress causing accelerating change: "The accelerating progress of technology and changes in the mode of human life, give the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue". Subsequent authors have echoed this viewpoint. I. J. Good's "intelligence explosion" model predicts that a future superintelligence will trigger a singularity.[6] Emeritus professor of computer science at San Diego State University and science fiction author Vernor Vinge said in his 1993 essay The Coming Technological Singularity that this would signal the end of the human era, as the new superintelligence would continue to upgrade itself and would advance technologically at an incomprehensible rate.

At the 2012 Singularity Summit, Stuart Armstrong did a study of artificial general intelligence (AGI) predictions by experts and found a wide range of predicted dates, with a median value of 2040.

Many notable personalities, including Stephen Hawking and Elon Musk consider the uncontrolled rise of artificial intelligence as a matter of alarm and concern for humanity's future. The consequences of the singularity and its potential benefit or harm to the human race have been hotly debated by various intellectual circles.

Philadelphia experiments

The Philadelphia Experiment is an alleged military experiment supposed to have been carried out by the U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, sometime around October 28, 1943. The U.S. Navy destroyer escort USS Eldridge (DE-173) was claimed to have been rendered invisible (or "cloaked") to enemy devices.

The story first appeared in 1955, in letters of unknown origin sent to a writer and astronomer, Morris K. Jessup. It is widely understood to be a hoax; the U.S. Navy maintains that no such experiment was ever conducted, that the alleged details of the story contradict well-established facts about USS Eldridge, and that the claims do not conform to known physical laws.

In 1955, astronomer and UFO buff Morris K. Jessup, the author of the just published book The Case for the UFO, about unidentified flying objects and the exotic means of propulsion they might use, received two letters from a Carlos Miguel Allende (who also identified himself as "Carl M. Allen" in another correspondence) who claimed to have witnessed a secret World War Two experiment at the Philadelphia Naval Shipyard. In this experiment, Allende claimed the destroyer escort USS Eldridge (DE-173) was rendered invisible, teleported to New York, teleported to another dimension where it encountered aliens, and teleported through time, resulting in the death of several sailors, some of whom were fused with the ship's hull.[5] Jessup dismissed Allende as a crackpot.

In early 1957, Jessup was contacted by the Office of Naval Research (ONR) in Washington, D.C., who had received a parcel containing a paperback copy of The Case for the UFO in a manila envelope marked "Happy Easter." The book had been extensively annotated in its margins, written with three different shades of pink ink, appearing to detail a correspondence among three individuals, only one of which is given a name: "Jemi." The ONR labelled the other two "Mr. A." and "Mr. B."

The annotators referred to each other as "Gypsies" and discussed two different types of "people" living in outer space. Their text contained non-standard use of capitalization and punctuation, and detailed a lengthy discussion of the merits of various elements of Jessup's assumptions in the book. There were oblique references to the Philadelphia Experiment (one example is that "Mr. B." reassures his fellow annotators who have highlighted a certain theory which Jessup advanced). Based on the handwriting style and subject matter, Jessup concluded a large part of the writing was Allende's, and others have the same conclusion, that the three styles of annotations are from the same person using three pens.

The ONR funded a small printing of 100 copies of the volume by the Texas-based Varo Manufacturing Company, which later became known as the Varo edition, with the annotations therefore known as the Varo annotations.

Jessup tried to publish more books on the subject of UFOs, but was unsuccessful. Losing his publisher and experiencing a downturn in his personal life led him to commit suicide in Florida on April 30, 1959.

Nanobots

You all heard about nanotechnology know a days the use and requirements of nanotech increase day by day . It more important utilisation in healthcare
The most dangerous deases of modern time is cancer there are many treatment of cancer like disease but after all this it causes thousand of death each year because medicine can't get to each cancer cells this can be solved by nanobots

Nanobots is also known as nanorobotics
Nanorobotics is an emerging technology field creating machines or robots whose components are at or near the scale of a nanometre (10−9 meters).More specifically, nanorobotics (as opposed to microrobotics) refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1–10 micrometres and constructed of nanoscale or molecular components.[4][5] The terms nanobot, nanoid, nanite, nanomachine, or nanomite have also been used to describe such devices currently under research and development.

Nanomachines are largely in the research and development phase, but some primitive molecular machines and nanomotors have been tested. An example is a sensor having a switch approximately 1.5 nanometers across, able to count specific molecules in a chemical sample. The first useful applications of nanomachines may be in nanomedicine. For example, biological machines could be used to identify and destroy cancer cells. Another potential application is the detection of toxic chemicals, and the measurement of their concentrations, in the environment. Rice University has demonstrated a single-molecule car developed by a chemical process and including Buckminsterfullerenes (buckyballs) for wheels. It is actuated by controlling the environmental temperature and by positioning a scanning tunneling microscope tip.

Another definition is a robot that allows precise interactions with nanoscale objects, or can manipulate with nanoscale resolution. Such devices are more related to microscopy or scanning probe microscopy, instead of the description of nanorobots as molecular machine. Using the microscopy definition, even a large apparatus such as an atomic force microscope can be considered a nanorobotic instrument when configured to perform nanomanipulation. For this viewpoint, macroscale robots or microrobots that can move with nanoscale precision can also be considered nanorobots.

Bio chip

The joint use of nanoelectronics, photolithography, and new biomaterials provides a possible approach to manufacturing nanorobots for common medical uses, such as surgical instrumentation, diagnosis, and drug delivery.So, practical nanorobots should be integrated as nanoelectronics devices, which will allow tele-operation and advanced capabilities for medical instrumentation

Nubots

A nucleic acid robot (nubot) is an organic molecular machine at the nanoscale. DNA structure can provide means to assemble 2D and 3D nanomechanical devices. DNA based machines can be activated using small molecules, proteins and other molecules of DNA. Biological circuit gates based on DNA materials have been engineered as molecular machines to allow in-vitro drug delivery for targeted health problems. Such material based systems would work most closely to smart biomaterial drug system delivery, while not allowing precise in vivo teleoperation of such engineered prototypes

Nano medicine

Potential uses for nanorobotics in medicine include early diagnosis and targeted drug-delivery for cancer, biomedical instrumentation, surgery,pharmacokinetics, monitoring of diabetes, and health care.

In such plans, future medical nanotechnology is expected to employ nanorobots injected into the patient to perform work at a cellular level. Such nanorobots intended for use in medicine should be non-replicating, as replication would needlessly increase device complexity, reduce reliability, and interfere with the medical mission.
I hope one day these nanobots are in every one body and save as from many kind of deadly dieses and increase our life expectancy.

Digital Immortality

The most feared thing in the world is death every one know he will die one day and thinking it's our fortune we are living. Many attempts from history has done to overcome death and increase human life expectancy but if we leave little bit success we don't get near our goal
But there is a way by which human can be immortal it is a hypothesis but research on it start decade ago.
This is digital immortality means integration of human and computers this is possible by  human consiuness or memory survive till long time. This seems to sceince fiction but it is true.
The futurist Ian Pearson believes that humans will achieve a kind of virtual immortality by saving into computers by the year 2050.The National Science Foundation has awarded a half-million-dollar grant to the universities of Central Florida at Orlando and Illinois at Chicago to explore how researchers might use artificial intelligence, archiving, and computer imaging to create convincing, digital versions of real people, a possible first step toward virtual immortality.
The Digital Immortality Institute explores three factors necessary for digital immortality. First, at whatever level of implementation, avatars require guaranteed Internet accessibility. Next, avatars must be what users specify, and they must remain so. Finally, future representations must be secured before the living users are no more.
Method of digital immortality

Reaching digital immortality is a two-step process:

archiving and digitizing people,
making the avatar live

Archiving and digitizing people

According to Gordon Bell and Jim Gray from Microsoft Research, retaining every conversation that a person has ever heard is already realistic: it needs less than a terabyte of storage (for adequate quality).The speech or text recognition technologies are one of the biggest challenges of the concept.

A second possibility would be to archive and analyze social Internet use to map the personality of people. By analyzing social Internet use during 50 years, it would be possible to model a society's culture, a society's way of thinking, and a society's interests.
