i always thought it was known fact that the universe has been expanding since it came into existence and eventualy particles with expand and break apart and eventualy the universe will cease to exist. this is fact right? i even learned this in school.

It is expanding. The rest is unknown...it may reach a point where it starts contractng again, or it may expand forever.

It is a fact (as measured by science) that the "known universe" WAS and probably still is expanding.
It is NOT POSSIBLE to know if the rest of the universe even exists today because we can't see the universe as it exists today. It takes a long time for the light of the universe to reach us. We don't see the universe as it is "now", we only see it as it "was". Of course, in all likelihood the universe is still expanding.
We don't know what happens after all of the expansion. We do know that every galaxy we observe seems to have a massive black hole in the center. It's quite possible that eventually those black holes will cause the galaxies to contract and explode again. But there is no scientific proof of anything like that.

The universe continues to expand after the Big Bang. There are some, myself included, who feel that one day the Universe will collapse again in the Big Crunch, after which the Big Bang will happen again and another Universe will start over. It will never cease to exist totally.

Depending on the average density of matter and energy in the universe, it will either keep on expanding forever or it will be gravitationally slowed down and will eventually collapse back on itself in a "Big Crunch". Currently the evidence suggests not only that there is insufficient mass/energy to cause a recollapse, but that the expansion of the universe seems to be accelerating and will accelerate for eternity (see accelerating universe). Other ideas of the fate of our universe include the Big Rip, the Big Freeze, and Heat death of the universe theory. For a more detailed discussion of other theories, see the ultimate fate of the universe. It will not cease to exist.

the universe IS expanding...and we can only see as far as the universe is expanding which is 13.7 billion years. (the big bang was 13.7 bill years ago)
i dont no if the universe will cease to exist...i took some college astronomy and they never said that. all i know is the farther the universe expands, the farther we can see into the past. but dont worry about the universe breaking a part... :D

Universe will never cease to exist. According to the Big Bang theory; expansion will one day stop and everything will come back once again.
Yes it has been proven that the Universe is expanding with solid scientific evidence such as the Redshift Phenomenon.

it really is subsequently far a idea. regardless of if the universe prolonged from its starting up and remains expandable it isn't yet shown to nevertheless be increasing. Its "glaring" or "observable" increasing fee will be an optical phantasm produced by the action of goods in area, in simple terms as rolling clouds in the course of the sky look transferring remote from the earth at a distance at the same time as they're truly in simple terms rotating around the earth. issues transferring remote from different products does no longer continually advise there is an increasing of area between them.

I'm no scientist, but I think we are finding more of it.....sort of like our world is getting smaller..Earth is a definite mass and with communications and travel, it feels smaller. Space seems larger because we are seeing further out. The universe is infinite..how fan you expand infinite, which has no end???

Yes, everything you said is right except the ceasing to exist part which is what they think, but are not totally sure of.

There is red shift everywhere we look.
I dont know how else to explain this.
