Real-life time travel differs from the type that has enthralled innumerable science fiction writers and spawned a genre so large.
Characters in shows like "Doctor Who," "Star Trek," "Steins;Gate" and "Back to the Future" hop into a crazy vehicle to travel back in time or spin into the future.
After traveling across time, the players must decide what happens if you modify the past or present with information from the future (which is where time travel stories intersect with the idea of parallel universes or alternate timelines).
Going incredibly quickly is the simplest and most practical approach to time travel into the remote future.
When traveling at speeds near the speed of light, time slows down for you in relation to the outside world, according to Einstein's special relativity theory.
This isn't simply a guess or a thought experiment; it's been proven. Physicists have demonstrated that a flying clock ticks slower due to its speed using dual atomic clocks (one flown in a jet aircraft and the other stationary on Earth).
In the case of airplanes, the impact is negligible. However, if you were on a starship traveling at 90% of the speed of light, time would move around 2.6 times slower than it would on Earth.
The time-travel becomes more intense as you approach closer to the speed of light.
Protons whirling through the Large Hadron Collider at 99.9999991 percent the speed of light are perhaps the fastest speeds achievable by any human device.
We may compute that one second for the proton is equal to 27,777,778 seconds, or nearly 11 months for humans, using special relativity.
Surprisingly, particle physicists must account for this temporal dilation when working with decaying particles.
Muon particles decay in 2.2 microseconds in the laboratory. Fast-moving muons, such as those produced when cosmic rays collide with the upper atmosphere, take ten times longer to disintegrate.
Einstein also influenced the next approach of time travel. The heavier the gravity you feel, the slower time advances, according to his general relativity theory.
The strength of gravity rises as you move closer to the Earth's center, for example. Your feet move at a slower pace than your mind.
This impact has also been measured. In 2010, scientists at the US National Institute of Standards and Technology (NIST) studied the variation in ticking rates of two atomic clocks positioned 33 cm apart on shelves. Because it had a somewhat higher gravity, the lower one ticked slower.
All we need is a location of incredibly intense gravity, such as a black hole, to go to the remote future. The closer you go to the event horizon, the slower time advances - but it's a perilous business because once you cross the barrier, you're stuck.
If you had the technology to travel the immense distances required to reach a black hole (the closest is around 3,000 light years away), the time dilation caused by travel would be substantially larger than the time dilation caused by orbiting the black hole.
Perhaps the most astounding fact is that GPS systems must account for time dilation effects (due to both satellite speed and gravity) in order to function.

Another approach to time travel to the future is to slow down or halt your physical processes and then restart them later.
Bacterial spores can exist in suspended animation for millions of years until the correct circumstances of temperature, moisture, and food reactivate their metabolisms.
During hibernating, some animals, such as bears and squirrels, may substantially reduce their cell's need for food and oxygen by slowing down their metabolism.
Though entirely shutting down your metabolism is probably beyond our present technological capabilities, some scientists are focusing on inducing a short-term hibernation state that lasts at least a few hours.
This might be just enough time to get someone through a medical emergency like cardiac arrest before they can go to the hospital.
In 2005, American scientists found that exposing mice to minute quantities of hydrogen sulphide, which binds to the same cell receptors as oxygen, might impair their metabolism.
The mice's core body temperature plummeted to 13 degrees Celsius, and their metabolism slowed by tenfold. After some time the rat succesfull reanimate
Similar trials with lambs and pigs were unsuccessful, suggesting that the procedure may not work for larger animals.
Time travel, which seems like something out of a science fiction movie, is already happening, but not in the form of a plutonium-powered DeLorean traveling through time.
It's already feasible to travel across time. A time machine has already been constructed. Scientists are still trying to figure out how to make it more efficient.
However, sending astronauts and subatomic particles into the future for a fraction of a second is far from the ultimate aim of time travel. Of course, the aim would be to transfer humanity through time's fabric.
Yes, time travel is a viable possibility. But it's not exactly like we've seen in the movies. It is possible to feel time passing at a rate other than 1 second per second under certain circumstances.
There are crucial reasons why we need to comprehend this type of time travel in the actual world.
