Is It Possible To Travel Back Into Time?
Is it possible to travel back into time? The Short Answer: Although humans can't hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. NASA's space telescopes also give us a way to look back in time. Telescopes help us see stars and galaxies that are very far away.
Why is it not possible to travel back in time?
The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity. Mathematically one can go backwards or forwards in the three spatial dimensions. But time doesn't share this multi-directional freedom.
Who invented time machine in world?
The idea of a time machine was popularized by H. G. Wells' 1895 novel The Time Machine. It is uncertain if time travel to the past is physically possible.
Who invented time machine in India?
According to our Mocktale sources, well-known scientist Sheshadri Cooperama has invented a time machine that would enable the leading aviation experts to travel back in time and bring a copy of the guidelines laid by Hindu sage Maharishi Bharadwaj.
Can a time machine be invented?
Time travel is already possible. In fact, a time machine has already been built. Scientists, however, are still working on how to make it as efficient as possible, like in the Back to the Future movies.

Do black holes exist?
Black holes of stellar mass form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. There is consensus that supermassive black holes exist in the centers of most galaxies.
Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen.
Which country made time machine?
The Iranian device sounds slightly more modest in scale than the time-traveling DeLorean from "Back to the Future," with its inventor claiming it can fit into a small case.
Where is time machine in India?
KOLKATA: Time Machine, one of the most popular attractions at Science City, is back in operation after a 20-month shutdown for upgrade. In its new avatar, the Time Machine is not only more vivid with a switch to LED screen instead of projection, the spectator capacity has also doubled.
How was time created?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today's clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
Can we see time?
Time is measure of duration and also referred as the fourth dimension. No we cannot see it. We cannot see it, but we can measure it. There are lots of things (for example, weight and temperature) like that.
How can time not exist?
The problem, in brief, is that time may not exist at the most fundamental level of physical reality. As Rovelli explains it, in quantum mechanics all particles of matter and energy can also be described as waves. And waves have an unusual property: An infinite number of them can exist in the same location.
What Albert Einstein say about time?
For example, physicist Albert Einstein's theory of special relativity proposes that time is an illusion that moves relative to an observer. An observer traveling near the speed of light will experience time, with all its aftereffects (boredom, aging, etc.) much more slowly than an observer at rest.
What did Einstein said about time?
Albert Einstein once wrote: People like us who believe in physics know that the distinction between past, present and future is only a stubbornly persistent illusion. Time, in other words, he said, is an illusion. Many physicists since have shared this view, that true reality is timeless.
Did Einstein believe in time?
In the Special Theory of Relativity, Einstein determined that time is relative—in other words, the rate at which time passes depends on your frame of reference. The effect of time slowing down is negligible at speeds of everyday life, but it becomes very pronounced at speeds approaching that of light.
Does NASA have a time machine?
The James Webb Telescope will peer farther back into the universe's history than ever before and is the "ultimate time machine," scientists say.
What existed before time?
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
Who is working on time travel?

|Known for||Time travel, quantum cosmology, relativistic astrophysics|
Who discovered Milky Way?
Galileo was the first to see the Milky Way Galaxy in 1610 as individual stars through the telescope.
Where is the nearest black hole?
For a comparison, Sagittarius A, the supermassive black hole at the center of the Milky Way, is thought to be about 4 million times the mass of the sun. In addition to being among the smallest black holes ever seen, it's the nearest one to us that we know of, at just 1,500 light years away.
Is folding space possible?
Something travelling on the surface of the paper at the speed of light would take a hundred years to get from A to B. For this reason, physicists think that travel great distances by "folding space" is highly unlikely to be possible.
Is time on a loop?
Einstein's general theory of relativity allows for the possibility of warping time to such a high degree that it actually folds upon itself, resulting in a time loop. The general conclusion that has emerged from previous research, including Thorne's and Hawking's, is that nature forbids time loops.
Who invented time clock?
Though various locksmiths and different people from different communities invented different methods for calculating time, it was Peter Henlein, a locksmith from Nuremburg, Germany, who is credited with the invention of modern-day clock and the originator of entire clock making industry that we have today.
Who made the second time machine?
The second of two Time Machine sequels written by American writer Burt Libe, it continues the story of younger daughter Belinda, now grown at age 22. Her father (the original Time Traveller) has just died from old age, and she and Weena (her mother) now must decide what to do with the rest of their lives.
