Is there ever an end to our Universe? If just empty space, how far would the empty space go? Would the empty space ever come to an end? and if so what would that be?

If the Andromeda Galaxy is 2.5 million light years away and it's the only galaxy on Earth to be seen by the naked eye, it leaves us to wonder how far it really is.
Personally, I googled it. I couldn't find a thing relating to the blank nothingness further than the universe.
I only looked a little bit, but there are very few educational guesses on the Internet.
Maybe you should try. Googling that is. Maybe it's you who'll find the right words to search it in.
The words stumped me so the was probably my problem.
Good luck on finding the answer!

Wow, these questions have been asked since the beginning of time (and by the greatest minds, so you are in good company!) I don't think science can answer them at present, it is too much of a paradox. If there ISN'T an end, why is everything here? How did it get there? How did someone make something out of nothing? And if there IS an end, where is an end? What is beyond the end? If it's nothing how can you get from something to nothing?
Be right back, I think I need some tylenol!

There is an end to the known universe. Quasars, the most distant luminous objects, mark this boundary. No one really knows for certain what's beyond that, simply because no telescope can see that far.
The universe is constantly expanding, so the boundary is always being pushed back.
One theory states that it will continue expanding forever.
Another theory states that the expansion will eventually stop & reverse itself & eventually, the universe will collapse in upon itself. This will be followed by another Big Bang & another cycle of expansion& contraction... and so on and so on...
It boggles the mind to think about these things.
These links might help.

Ah...one of the great unsolved mysteries.
Space is beleived to be finite...somehow in a manner that is simultaneously boundless and closed. Curved into a 4th dimension. bear in mind that space in its entirety is only 3 dimensional. That means there'a directions that exist that you can't even point at....there's length, width, height...and then there's "?"...Einstein says its Time.
The edge of the known universe is 15 billion light years away....seeing that the speed of light is finite, that means you actually see things "as they were" at a rate proportional to how far away they appear---since it took the light that long to get here.

The universe is infinite.
There is no beginning and there will be no end. It's hard for our minds to comprehend this because everything in this life time had a beginning and an end.

we really dont know how far until nothing. one reason is that light only moves at 2.998m/s so we cant and will never be able to see the edge of the expanding universe. Also the universe's expansion rate is increasing.
