Professor Stephen Hawking Reveals 3 Ways We Can Travel In Time

So… time travel is possible… at least theoretically.

Traveling in time has been one of the greatest fantasies of the human being for centuries. It is a popular trend in movies and science fiction series, and the idea has inspired novels from Charles Dickens’ The Christmas Tale, to Charlton Heston’s The Planet of the Apes masterpiece.

So… is time travel achievable? If we take a look at the last couple of years, we will notice quite a few scientific studies that have researched the idea of traveling in time.

We’ve written about the idea of time travel, and the studies which have looked into the possibility of traveling in time quite a few times in the past.

We covered an article that suggests how scientists found out that ‘mathematically’ time travel is possible.

“People think of time travel as something as fiction. And we tend to think it’s not possible because we don’t do it,” said Ben Tippett, a physicist, and mathematician from the University of British Columbiasaid in a UBC news release, adding “But, mathematically, it is possible.”

By using Einstein’s Theory of General relativity as the basis for a hypothetical device which they named a Traversable Acausal Retrograde Domain in Space-time (TARDIS), scientists have come up with a mathematical model of a theoretical time machine box that has the ability to move back and forth through space and time.

Interesting comments about Time travel were made by Astrophysicist Ethan Siegel of Lewis & Clark College wrote the Forbes blog Starts With A Bang: “While we still haven’t discovered the conditions we need to travel back in time and find the necessary means by which we can create a large enough system for humans to do so, ‘nothing is forbidding it’ in the laws of theoretical physics.”

But perhaps the scientist who most embraces the idea of time travel as a possibility is astrophysicist Professor Stephen Hawking who suggests there are three ways we can travel in time.

According to the famous British astrophysicist, there are at least three (hypothetical) ways in which it would be possible to travel through time.

The first one would be to travel in time through a wormhole, a central figure of theoretical physics that quantumly represents a point in spacetime that connects with another. If we were to find a way to enter a Wormhole, we could then create a tunnel between two points in space-time.

The second theory according to Professor Hawking would only allow us to travel to the future, and it would mean the traveler would have to approach a black hole, capable of dramatically slowing down time, and then returning to Earth, where time would have passed normally.

Finally, the British scientist proposes that the most viable alternative to building a time machine would be to build a device capable of moving around the Earth at the speed of light, which would allow the life of its passengers on board to pass 7 thousand times faster than on Earth, allowing a shift to the future.
