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.
Is Travelling back in time possible?

How do I travel to the past?
The simplest way currently being discussed is to take a
wormhole
(a tunnel connecting spatially separated regions of space-time) and give one mouth of the wormhole a substantial velocity with respect to the other. Passage through the wormhole would then allow travel to the past.
Can you go back in time through a wormhole?
Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as in space. … However, according to general relativity,
it would not be possible to use a wormhole to travel back
to a time earlier than when the wormhole was first converted into a time “machine”.
Will a time machine ever be invented?
Time Travel Is Possible:
Scientists Have Already Built A Time Machine
, Actually. Time travel, a concept straight out of science fiction movies, is actually already happening, but not in the form of a plutonium-powered DeLorean jumping to the past and future. … In fact, a time machine has already been built.
Is it possible to travel faster than light?
Physicists’ current understanding of spacetime comes from Albert Einstein’s theory of General Relativity. General Relativity states that space and time are fused and that
nothing can travel faster than the speed of light
.
Does past still exist?
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever.
The past would therefore still exist
, just as the future already exists, but somewhere other than where we are now present.
What is the formula for time travel?
In fact, according to Albert Einstein’s famous equation,
E = mc2
, time travel is possible, at least in one direction.
Can we go to our past?
The fact that the universe is still around is ample evidence that
time travel to the past is impossible
. … There are many speculative theories about time travel to the past, some made by respected physicists, but mainstream physics does not allow it.
Is it possible to go back in time and change the past?
Time Travel Theoretically Possible Without
Leading To Paradoxes, Researchers Say In a peer-reviewed journal article, University of Queensland physicists say time is essentially self-healing. Changes in the past wouldn’t necessarily cause a universe-ending paradox. Phew.
Can a wormhole be created?
To create a wormhole on Earth, we’d first need
a black hole
. This is problematic: creating a black hole just a centimetre across would require crushing a mass roughly equal to that of the Earth down to this tiny size. Plus, in the 1960s theorists showed that wormholes would be incredibly unstable.
Is a wormhole possible?
Wormholes, like black holes, appear in the equations of Albert Einstein’s general theory of relativity, published in 1916. … “From a mathematical perspective such a shortcut would be possible, but
no one has ever observed a real wormhole
,” the physicist explains. Moreover, such a wormhole would be unstable.
Can Earth go into a black hole?
Will Earth be swallowed by a black hole?
Absolutely not
. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them.
Can you build a time machine?
Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality.
Why does time stop at the speed of light?
Space itself is shortened and time itself is slowed down for a moving reference frame, relative to the stationary observer. … In the limit that its speed approaches the speed of light in vacuum,
its space shortens completely down to zero width
and its time slows down to a dead stop.
Is time machine invented 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.
