The truth about time trips is, according to science: “theoretically, that’s possible”

From the output of works such as Time machine From HG Wells to the picture Star D Kristopher Nolan, The opportunity to travel over time He attracted the public for centuries.

But, even though it seems like pure science fiction, the real science Maintains that these trips are possible In fact, scientists say that people have already done Daily mail In a statement.

Of course, those trips have nothing to do with movies. This may seem obvious, but here we all move on to the speed of time One second per second.

However, thanks to the theory of general relativity, exposed Albert EinsteinYou can travel at high speed over time. Can move someone faster, Can travel fast in timeCenturies jumps for centuries for a few minutes as light approaches the speed of light.

This effect is very low at low speed, thus, astronauts at the International Space Station (ISS) They all ‘passengers at the right time’ For that ‘jump’ for the future.

In the pictures, the time journey is usually sent to a machine and is sent to a completely different time and space in the past or future. However, not about the real -time journey Go from one point to another in the chronology.

According to NASA, ‘Travel in Time’ travels faster than a second per second. Although it seems impossible, the space agency says that it is actually possible. In fact, we are all progressing at different speeds depending on where we are and how fast we are. Vibrate Travelers are around us every day at the right time.

And 1915, Albert Einstein He presented his general relativism theory The Prussian Academy in Berlin showed that it could travel in the Academy of Science and timely. As this situation appears, Einstein’s principles show that this type of journey is not possible over time, but very common.

Herd Alexander RichmundSays the philosopher and time travel expert of the University of Edinburgh Daily mail: “Einstein teaches us that the speed of time in our environment varies according to our speed.” Basically, this means that you travel fast, and you enjoy the slow time.

So, yes You are on a plane or on a trainYou will experiment with time passing more time than no one has stopped, and tests show that this is true.

Astronauts are the ISS. 28.100 kmQuickly enough to enjoy a small journey at the right time.

For example, NASA’s astronaut Scott Kelly He spent 520 days at the station and as a result, slightly slower than his same twins, Mark KellyIt stayed on earth.

Although these effects are subtle, they are common enough to cause technical problems Precision systems such as GPS satellites.

Like satellites Around 14.000 kmThey are constantly progressing in time, and their on -board watches must take this difference into account. If GPS satellites are not suitable for time trips, they are unable to determine their own space in space and are useless for accurate navigation.

Traveling to the past?

Although the timely advancement is the natural effect of physics, traveling to the past is a different story. “Traveling at the right time is a lot, very complicated“Says Dr. Richmund.

However, although this is practically impossible, Richmund points to traveling backwards “This is theoretically possible.” This is because you need a folding time and space to move backwards.

Peter Watson, the theoretical physicist of the University of Carleton, says: “The intensity of Einstein’s formula may be died: in fact, it is the intensity of Einstein. In principle, in principle We can create such a curved space time That he had a hole. “

The resulting structure is known as a worm hole or a subway through space time. Unfortunately, hold a standard worm hole for a long time to cross it “Negative mass” is requiredThis is only a theoretical possible.

In addition, although a worm hole or other device can be used to create A ‘closed temporary ring’, We cannot use this to travel beyond the day it created.

Dr. Richmond points out: “If I create the first temporary curve generator to be closed tomorrow afternoon I could not use it to travel No time before tomorrow afternoon“.

So, it is theoretically possible to go back and travel time to meet your ancestors This is not possible yet.
