What do you think?

Ours.

But that's a bad frame of reference to compare with the age of the universe, because we are in motion.

Ours.

But that's a bad frame of reference to compare with the age of the universe, because we are in motion.

As you said before ours isn't the same, so that isn't the reference point. Was kind of a trick question to get you to realise things aren't loosely defined like saying "our" reference point.

To answer your other post it's a case of knowing what the definitions are. Just because you read something and think you know what all the words mean when it comes down to science you probably don't. A year is a well defined thing.

That being said the word year gets thrown about with loads of different meanings, you only have to look at the wiki page for that. So when people say things like a year is how long it takes the earth to orbit the sun, well no as that changes everytime it happens, same for a day. Some days are > 24 hours, others less*.

*By this I clearly mean more and less than the real average time it takes the for a day, I dunno if it would ever be < 24 hours as I don't know how much fluctuation we see.
