science says that ever since the big bang, our universe has been expanding. And yet, as we know from trips to the moon there are infact places in the unverse where there is no gas, liquid, or solid, and there is a lot of this nothing, how can the edges be "nothing" and still be expanding?

The universe has no edges. All of space is uniformly filled with galaxies everywhere. But there is more distance between the galaxies today than there was yesterday.

Our universe isn't increasing into something it really is unbounded. attempt to imagine stretching an infinitely huge mattress sheet. you spot that is the mission with this stuff, it would not make experience. there's a language for this (mathematics) and none of it translates. you may't visualise it, no you'll, and it does no longer make experience to the human suggestions. We physicists can do the mathematics on it, all of us understand it extremely works, we may be able to educate it extremely works and we may be able to educate you ideas all of us understand all this stuff extremely is real, yet we can't image it. you'll never, ever get an answer the position you may flow "oh yeah it extremely is wise". It never will. Physics on the extremes is in basic terms too strange. once you get to the speed of sunshine, or the potential of a black hollow, or the size of the quantum, physics in basic terms works otherwise. It has no each day analogue it does some extremely strange **** and the human mind is going "that would want to't be real", notwithstanding that's.

The universe is expanding but we are the reference point. Every star, planet, galaxy, and so on are seperating. In the big bang, there was only matter. That matter seperated unimaginably quickly. The universe isn't stretching, everything is just moving away from each other. Way into the future, even atoms will seperate and only matter will be left again.

Empty space is also thought to curve. It curves differently around objects and gravity is created. Apparently, holes get punched in empty space. The wormhole idea is one such theory. Short cuts in space travel may be possible through these holes. Am I answering your question? No. Just expanding on it. I am not equipped to answer it. I just relate to it. We can only conclude that we don't really understand empty space. Why should we? We are conditioned to a lack of matter as being empty. But perhaps ultimate emptiness doesn't really exist.

its really stranger than that!
one of the ways we can tell the Universe is expanding is the 'red-shift' that nearly all galaxies exhibit in their spectra. (cept Andromeda... IT'S COMING RIGHT AT US!)
How much red-shift indicates how fast the galaxy is moving.
In some cases, the red-shift shows that the galaxy is moving faster than light.
gasp
okay, don't panic... no, things really can't travel that fast so SPACE must be expanding around us... sorta like driving on a moving sidewalk.

this helped me 'see' it.... someone explained it like this... put a lot of dots on the outside of a deflated balloon... now blow it up ....as it expands, all the dots move away from each other as the balloon expands.. but so does the empty spaces!.... they expand as well.... so there nothing inside the balloon, and in the Universe, there's nothing outside the balloon either... there's just all this energy and matter that makes up the expanding balloon............help at all?...
