Turns Out It’s Not Possible to Time Travel Just by Flying Really Fast

[ad_1]

The potential for time journey has excited many people for tons of of years, inspiring numerous books and movies. The flexibility to maneuver not solely by area however into the previous or future would open a myriad of potentialities for humankind.

 

However is it theoretically even potential to time journey?

Within the authentic 1978 Superman movie, Superman goes again in time by flying across the globe sooner than the velocity of sunshine. That is extremely quick – the velocity of sunshine is just below 300,000 km per second!

Up to now, we have now not come even near this velocity, the quickest man-made object, an area probe, traveled at simply 150 km per second.

Given the suitable technological developments, is it theoretically potential for us to journey sooner than the velocity of sunshine, and thus, like superman, journey in time?

We requested 6 specialists in astrophysics, astronomy, and physics, ‘Is it potential to time journey by going sooner than the velocity of sunshine?‘, here’s what we discovered…

Will we expertise time in a different way after we are touring at velocity?

Einstein’s idea of relativity determines that point just isn’t common – it’s relative. The 1971 Hafele-Keating experiment discovered {that a} clock that was flown on an airplane touring at velocity fell behind clocks that remained on the bottom.

Extra not too long ago, exact atomic clocks have been discovered to run at totally different speeds when one is moved relative to the opposite. This phenomenon known as ‘time dilation‘.

Dr Sean Matt, an knowledgeable in astronomy and astrophysics from the College of Exeter within the UK, says, “If one travels near the velocity of sunshine, time behaves in a different way than we’re used to, and on this method, one can transfer ahead in time sooner than these left behind. So it’s theoretically potential to journey to the longer term, however one couldn’t return.”

 

Is it potential to journey sooner than the velocity of sunshine?

All of the specialists agreed that it’s not potential to journey sooner than the velocity of sunshine, that is additionally laid out in Einstein’s idea.

Dr Eric Tittley, an knowledgeable in astronomy and astrophysics from the College of Edinburgh, explains, “It’s clear that no object or data can journey sooner than the velocity of sunshine. It isn’t a query of not having sufficient vitality to push it that quick. From an exterior perspective, any additional vitality added to a physique to get it to and previous the velocity of sunshine simply asymptotically accelerates it to the velocity of sunshine.”

‘Asymptotically’ that means one thing will get nearer and nearer to the velocity of sunshine, however by no means fairly reaches it.

No object can journey sooner than the velocity of sunshine as a result of as objects journey sooner, they get heavier. Due to this fact, it is just mild that may journey on the velocity of sunshine – as a result of it has no mass.

The takeaway: Travelling at velocity can change your expertise of time, however time journey by touring sooner than the velocity of sunshine is unfortunately not potential.
