"Forever" is a long time, and most scientists are not arrogant enough to think we know everything. For example, we don't know whether the universe is really expanding (although that seems the simplest explanation) and we don't know if it will ever reverse and collapse again.
Logically, if the universe expands forever AND all the mass that will ever exist came into being in the big bang, then eventually when all the existing stars have burnt out, the universe will become cold and dark. We don't know that there is no "new" mass coming into being; Sir Fred Hoyle, who derisively named the "big bang", believed in a "steady state" universe in which new matter might come into existence in the space between the stars.
The total history of stellar physics and cosmology is scarcely 100 years old; I suspect that we barely have begun to suspect the real truth about what's happening. Keep an open mind.
What else can I help you with?
If all galaxies began to show blue shifts what would this change indicate about the fate of the univerese?
That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.
What are the universal things?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?
What would happen if the cell cycle stopped?
All life would end
How would you describe what is ment by the big bang theory?
The Big Bang Theory presents the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang promotes that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
What would happen to a eukaryotic cell if it's mitochondria was destroyed?
It will not get energy. Functions of cells would be stopped
What would happen if the galaxies in the universe start expanding faster than the speed of light?
we would be all screwed
If the universe was expanding with 0 acceleration what would the age of the universe be?
The universe simply cant expand at 0 acceleration.
What things are beyond the universe?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?
What is beyond the expanding universe?
The universe contains space and time. "Outside" the universe, there would be no space or time, and without these, nothing can exist.

If gravity dominates the expansion of the universe what would happen to the universe?
If gravity dominated the expansion of the universe, the universe would eventually stop expanding and begin to contract. This would lead to a "Big Crunch" scenario where all matter in the universe collapses back into a hot, dense state.
Fifty brightest stars in the universe?
That question cannot be answered. We would have to know the magnitude of every star in the universe. The universe is infinite (and expanding). It's impossible to answer your question.
Does this expanding universe model mean that the milky way galaxy is the center of the universe?
No it does not. It is my basic understanding of this theory that the 'true center' of the universe would be mostly devoid of material.
What would happen if a person ate expanding foam?
stomach explodes
Is the universe curve and for ever expanding?
The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past). It may be reasonable to assume that this trend will continue in the future, but it would also be a little premature to be completely sure.The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past).

Would the zip code for the universe be infinite?
I suppose because the universe is constantly expanding, so you could never pinpoint just one area.
