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.

    It’s 30km/s not m/s. They were still able to see the difference on atomic clocks moving on airplanes that were barely off the ground and much, much slower than 30km/s.

    Also what about combining Earth’s axial rotating ~450m/s with it?

    I mostly wonder if we compare us (Earth) with someone orbiting much slower or much faster, would the time difference still be negligible or not?
