Scientists confirm that time travel is possible and claim that people have already done it

Scientists claim that time travel is possible and humans have already done it, according to the Daily Mail. From H. G. Wells to Christopher Nolan’s “Interstellar“, the possibility of time travel has excited people for centuries.

But while it sounds like pure science fiction, physicists now believe that time travel is actually possible. In fact, scientists claim that humans have already done it.

Cinema has dealt quite a bit with the subject

Experts warn that real time travel is nothing like what we see in the movies. It may seem obvious, but here on Earth, we all move through time at a rate of one second per second.

However, thanks to Einstein’s theory of general relativity, it is possible to travel through time at a higher speed.

The faster we move, the faster we can advance in time, jumping centuries in a matter of minutes as we approach the speed of light.

Although this effect is imperceptible at slower speeds, it means that all astronauts on the International Space Station (ISS) are “time travelers” moving into the future.

In films like Terminator, time travel often involves jumping into a machine and moving to a completely different time and place in the past or future. However, real time travel is not about jumping from one point to another on the timeline.

According to NASA, “time travel” is traveling faster than one second per second. And while it may seem impossible, the space agency says it is possible.

In fact, we all move through time at different speeds depending on where we are and how fast we are moving. That means time travelers are all around us every day, and you could be one too.

Einstein’s theories prove time travel

In 1915, Albert Einstein presented his theory of general relativity at the Prussian Academy of Sciences in Berlin and proved that time travel is possible.

Strangely enough, Einstein’s theories show that this kind of time travel is not only possible, but extremely common.

Dr Alasdair Richmond, a philosopher and time travel expert from the University of Edinburgh, told MailOnline: “Einstein taught us that the speed of the passage of time in our environment varies according to our speed.”

In essence, this means that the faster we travel, the slower we experience time.

So, if we are on a plane or a train, we will feel time slower than anyone who is still, and experiments have shown this to be true.

Joseph Haefele and Richard Keating confirmed it

In 1971, two scientists named Joseph Haefele and Richard Keating decided to test Einstein’s theory by inducing time dilation here on Earth.

The scientists took two ultra-precise atomic clocks and loaded them onto commercial aircraft capable of flying around the world in a single flight.

One clock was sent east and the other west, and then compared with a third clock that remained stationary on the ground.

The clock that moved eastward with the Earth’s rotation moved faster than the one on Earth and therefore less time elapsed.

At the same time, the clock moving westward against the Earth’s rotation was moving more slowly than the clock on Earth and therefore elapsed more time.

And just as general relativity predicted, when the clocks landed, Haefele and Keating found that the eastbound clock lost 59 nanoseconds, while the westbound clock gained 237 nanoseconds.

According to this theory, anyone who spends a lot of time moving at high speed is a time traveler.

The astronauts aboard the ISS orbit the Earth at almost 28,100 km/h (17,500 mph), a fast enough speed to experience time travel.

For example, NASA astronaut Scott Kelly has spent 520 days on the station and, as a result, has aged slightly slower than his identical twin brother, Mark Kelly, who has remained on Earth.

Although these effects are imperceptible, they are common enough to cause technical problems in precision systems such as GPS satellites.

Since satellites orbit at approximately 14,000 km/h (8,700 mph), they are constantly moving forward in time, and their onboard clocks must account for this difference.

If GPS satellites do not adapt to time, they will not be able to determine their own position in space and will be useless for accurate navigation.

While traveling forward in time is a natural consequence of physics, traveling backward is another story.

“Traveling backwards in time is much more complicated,” says Dr. Richmond.

However, although in practice it is probably impossible, Dr. Richmond notes that traveling backwards in time is “theoretically possible.”

Reversing requires bending time and space.

Professor Peter Watson, a theoretical physicist at Carleton University, states: “You can curve space-time using mass: that is, in fact, gravity in Einstein’s formulation.

In principle, we could curve space-time so much that it would form a hole.

The resulting structure would be known as a wormhole or a tunnel through space-time.

Unfortunately, keeping a wormhole stable long enough to pass through it requires “negative mass,” which is only a theoretical possibility.

In addition, even if we could use a wormhole or other device to create a “closed time loop,” we could never use it to travel beyond the day of its creation.

Dr. Richmond notes: “If I built the world’s first closed time curve generator tomorrow afternoon, I couldn’t use it to travel to any time before tomorrow afternoon.

So, while time travel may be theoretically possible, traveling to reunite with your parents like Marty McFly in Back to the Future remains impossible.
