Its quite simple. Just observe the galaxies and u will find that galaxys are moving away with each other this concludes that universe is expanding
There is no mathematical proof that space is infinite. All we know is that there is an expanding limit to what we can see.
Yes.
The distance between galaxies is increasing, pretty much in all directions. This suggests that space itself is expanding. We also now know the rate of expansion is in fact increasing.
No. It is space itself that is expanding.
The universe began with the Big Bang about 13.8 billion years ago. During this event, all matter and energy were concentrated into a single point before rapidly expanding, creating space and time as we know them. Since then, the universe has been continuously expanding and evolving.
It is space that is expanding. The amount of matter doesn't necessarily increase. This means that the average density of the Universe is decreasing.It is space that is expanding.

It is not exactly expanding into anything. We don't really know.
no one is quite sure where the universe begins or ends but what they do know is that the universe is continuously expanding. they also believe that one day probably a trillion years from now that it will stop expanding and shrink and then we will have another big bang.
That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.

What is the name of a vast expanse
Space goes on for trillions and billions of kilometres and miles and is still expanding this very minute!
Space doesn't, strictly speaking, have a beginning and end. That is, it's like a bubble with infinite diameter. It is rapidly expanding, but as far as we know, it doesn't have any definable boundaries.
