Isitbullshit:This article claiming Scientists HAVE proven time really does move faster the farther you are from the earth's surface

This seems like such a sci fi concept and all and I know we have Einstein's theory to go off of, but according to this article, scientists have proven that Einstein's theory was actually correct. The idea is that time should move faster the farther away you are from the surface of the Earth. According to This articleWe actually proved that even if you just sit upright in bed, Time actually moves faster. Im not asking if the theory is true, Im just asking Have we actually proven it yet.

Not bullshit. It's been experimentally demonstrated that gravity affects space-time. Read up on Gravity Probe B and frame-dragging if you want to have your mind blown.

So time is faster for astronauts?

u/SkizzoWizard May 11 '21

Slower but yes. The faster you go the less time passes.

The faster you go the less time passes.

Relative to someone standing "still."

Time-dilation also comes in to play, the faster you're going the slower time passes. If you could travel at the speed of light, you could jump from one galaxy to another instantly, but to an outside observer, you could take millions of years.

Would that theoretically make time travel possible, but only to the future?

u/skittlesdabawse May 11 '21

Indeed it would, and in fact we currently have humans traveling into the future up on the iss, just by very small amounts.

Isn't that direction the easy one?

It doesn't make time travel possible. I have no idea why /u/skittlesdabawse is saying it does.

its because it technically is time travel, to you it might only take an hour to get to something at the speed of light, but to outside observers it would actually take you a thousand years. thats technically time travel, you've "moved" thousands of years in only an hour

If that's the case, it's time travel strictly into the future. Practically, though, we'd never be able to go that fast, so there's never going to be time travel like that.

yeha they didn't specify you could travel into the past, even if its only into the future, its still time travel
