Scale of the Universe

I would recommend to anyone that they get a picture of the solar system / galaxy / universe as their desktop wallpaper, especially at work.

It really helps you realise just how small your problems really are

Ok I'm 13 and have had no real education to help me understand my question, so it's probably extremely stupid, but how can they possibly estimate the size of the universe? Surely it just goes on forever and ever and therefore has no limited size? If anyone could explain I'd be really grateful

What... lucothefish on mah Scorehero? UNPOSSIBLE. (Sup bro, long time etc.)

I love that Imagining The 10th Dimension lark. All this 'scale of the universe' thing makes me feel sort of small and insignificant, but in a good way... kinda like luco said: if you think about your problems in a cosmic sense, it's all fucking trivial.

Holla back at ya Cap'n... wow 6,000 posts, someone's been a busy boy

I have an actua headache from reading that 10th dimension thing

OK thanks a lot for that

Also @ OP thanks a lot for that size comparison thing, it's really cool

My mind has officially been blown on every level possible. I've always been curious about the different dimensions, and now I finally understand.

Just for the record guys, the 10th dimension video isn't really synonymous with what modern quantum physics believes, it's just a good way to put into perspective the scale of adding each dimension, and having a really cool and simple way of trying to visualize it.

As for the universe not being infinite, and expanding, they basically mean the area containing matter. The universe in the sense that I had always thought of it actually is infinite and static, and a very small portion of that is occupied by what scientists consider the universe. As far as I'm concerned, if you were to teleport to a place that is a full lightyear farther from the center of the universe than the current piece of matter that is farthest from th center, then the same physics would apply, and the same space-fabric would be present... so I see no reason why the definition of the universe should only include the region containing matter, and not the region outside of that. We have no way of knowing whether there is another "universe" of matter that would exist far outside of our own, say another several trillion lightyears away, that had once had it's own 'big bang' and all... that would follow the same laws of physics, and etc. That would be far enough away that we would not be able to detect the light from it, but since our universe is the region containing all the matter, by our definition our universe would then contain the two universes but nothing more, even though we would surely consider the possibility of a third and possibly infinite others. Now I'm not saying that a different universe could not exist that would have different physics, just that we could not travel to it by venturing any distance. If there were to be another place where there were different physics that was not connected to our own universe by any amount of distance, then THAT is what should be considered a different universe, and a part of an overall multiverse. But that's just my opinion. Let me know if any of you agree.

Now that I think of it, our universe is supposedly 13.7 billion years old, and how far we could see would be 13.7 billion light years, because that's how far light can go. What if the reason we thinkk the universe is expanding is because the light from farther and farther away is getting to us, and we're able to see further and further?
