@athousandyoung saidLOL!
You’re wrong because there is no difference between us moving away from an object and an object moving away from us
That is exactly what I said which is why I am right.
How can you tell the difference?
@Metal-Brain
And why do you think that fundamentally matters? The main thing is the recession velocity, it matters little who is going away from whom.
@sonhouse saidIt matters if you cannot distinguish the difference. Can you?

@metal-brain saidNo, it's not.
That is exactly what I said
"Either the galaxy moving away from us or us moving away from the galaxy", which is essentially what you said, is a fundamentally un-relativistic statement. The reality is "Us and that galaxy having a relative movement".

@sonhouse saidIt matters a lot - because it's neither. It's relative movement, not one moving away from another.

@shallow-blue saidIt is both. You just said so by saying it is relative movement.

You contradicted yourself.

None of you can explain why I am wrong but you are the last word. Right.
Tell us again why you think time dilation is the result of gravity.
Simply tell us all why gravity would cause time dilation.
We are all waiting.
According to Einstein, there is no difference (at least you cannot tell from inside a spaceship) between sitting on a planet with 1x Earth gravity and traveling through space at a constant 1G acceleration. Either way, with sufficient speed OR gravity, you will experience time dilation. Since you can experience time dilation without gravity, therefore time dilation does not cause gravity. In fact, it is gravity (OR acceleration) which causes time dilation.
Savvy?

That proves nothing. I refer you to the equivalence principal.
" In fact, it is gravity (OR acceleration) which causes time dilation."
False. It is both.
This is the last time I will correct your nonsense.
If we cannot see light from galaxies in the distant universe it does not prove the universe is expanding faster than light. It is possible there is no light there to see there, but let's assume there is light and it has not reached us because it is too far way. That would prove 2 things.
1. Our galaxy is not anywhere near the center of the universe.
2. The universe is expanding more than half of the speed of light
Think about it. It will come to you.
@shallow-blue saidYou don't know the difference between a radius and circumference, do you?
Mate, you're so far out of your depth, you're not even in the swimming pool any more.

No, worse. Children can be taught.
