Time Travel Is Possible – But Only To The Future

This is a bitter sweet story as we've learned that time travel is possible. The bitter part is that there can't be a real life Back To The Future...because you can only go to the future, which obviously means you wouldn't be able to come back to the time that you left in the past. Keep reading to find out how time travel is possible!

From Inquisitr, particle physicist Brian Cox says:

“The central question is, can you build a time machine? The answer is yes, you can go into the future,” he said. “You’ve got almost total freedom of movement in the future.”

Under Albert Einstein’s theory of relativity, an individual could travel hundreds, even thousands of years into the future if they were moving fast enough. How fast? Speed of light fast.

“Imagine twins, one stays on Earth (Twin A) while the other (Twin B) boards a spaceship and flies off at relativistic speeds. Compared with Twin A’s timeframe, Twin B’s timeframe will slow. If time is running slower for Twin B, then he/she will return to Earth where a lot more time has passed and Twin A has aged significantly more than Twin B. The mechanism behind this is ‘time dilation’ and it has a stronger effect as you travel closer and closer to the speed of light.”

The only problem is that once you get to the future, you’re stuck there. Additionally, traveling backwards is almost completely out of the question.

Citing the popular cult show Doctor Who, Cox said that traveling to the past would only be possible via a wormhole. Problematically, this theoretical shortcut through space-time, also proposed under Einstein’s general-relativity theory, has never been proven to exist, and we have no idea whether we’d even be able to use it to travel back in time anyway.

 

Would you take a chance and go into the future if the opportunity arose?
