If it’s 2 million light years away at the speed of light, it would still take 2 million years if traveling at the speed of light. Simple math.

Plot twist, we sent beings into space millions of years ago to search out new life and colonize other planets. When the come back, we think they’re aliens.

So let me make sure I understand this correctly. In this scenario, you would age 7 years while the earth aged 400 million years? Or would you age at the same rate as if you were on earth?

So, maybe the aliens we could eventually meet, are just astronauts from earth a long time ago and from an extinct species.

almost speed of light. 2 million light years. why would it take us only 2 years if we're traveling same speed as light? math at mathing

So does the recipients of the andromeda galaxy seeing the astronaut travel for 2 million years before reaching them? If it took that long, do they even notice or does he just show up one day

Doesn't this mean light travels slower on Earth, and faster in Space. So light can not be used to measure distance or time in space. So our closest neighbors are just around the corner, in Space.

Yeah but what if you could travel at ludicrous speed?

We will never be able to fly at the travel at the speed of light because it’s impossible with anything that has mass

Why. It’s the same distance but you’re just traveling faster

So if it’s 2 million ‘light years’ away, how would it take 7 light years at the speed of light?

how much would you age? would you age the 4 million years or the 7 years?
