3. i took 2 college astronomy classes last year...
but I'm no expert. However, I did do my homework.

It's hard to conceptualize in a way. And I'm no good with the math. I can only do the math with someone walking me through it.
I get the theory, mostly. Don't ask me to do the math.

But I think it has something to do with the fact that
the earth has it's own time,
the moon has it's own time
the rocket would have it's own time as well
...they probably didn't take the same route back that they took there....
they were also on the moon for a while.
I think that would do it?

I wouldn't think that it was an enormous time difference.
My guess would be a few minutes at the most, maybe a few seconds. I don't know. Can't be that much.

Mass affects the time...if a clock is closer to the larger the mass, the slower the time...and vice versa smaller mass/faster time

And no, the earth is not the center of the universe, as the sun and planets formed in kind of a centrifuge fashion...with the heavier stuff at the middle, and gasses and junk toward the outside. I'm oversimplifying that, but they are finding this to be true, more or less, in other planetary systems as well. The earth does go around the sun...or rather the sun and the earth rotate around a central point, which I think is probably pretty close to the sun because of the larger mass of the sun.

anyway...i think that's right.
