When we talk about the speed of light, black holes and compare the space-time, it’s always based on our home and laws living on the Earth.

But what about theoretical other planets and life? Since Earth is moving 30 km/s around the sun and rotating around 450 m/s, does it mean that we age(d) much slower as species on Earth compared to some distant unknown planet that is orbiting much slower?

So its potential inhabitants already went extinct or have severely shorter life span compared to us? And vice versa - could be that we are aging much faster on Earth compared to a planet out there that is orbiting its star at super high speeds? Also does planet’s axial rotation affect this or not?

Thanks.

    Noticeable time dilation requires going faster than anything in our solar system. To figure out the time difference in this case, use that velocity to compute the Lorentz gamma, then multiply the elapsed time by that.

      Why the hell would somebody downvote that?

      If it’s the precession of mercury’s perihelion, okay. But I think a lot of times, I get banned from subreddits because people don’t like my attitude or they don’t like my job.

      I can’t believe that used to worry me.
