We don't know whether there is life in the universe so we don't know why because we don't know if there's any life out there if you get my drift
No.
Yes there are some unanswered questions in life like how was the universe formed
There will be an end to life but not to the universe the universe will keep exopanding .Our life will end in about 4.5 billion years becuase the sun will have no more hydrogen to live off of and will explode.Remember life can not go on without the sun we need liquid water not solid water.
None that are known. Earth is the only place in the universe known to have life and it is highly unlikely that any of the dwarf planets in our solar system have any life.
JESUSAlternate:The Answer to Life, the Universe, and Everything in Hitchhikers Guide to the Universe by Douglas Adams is "42" . This is as intrinsically as satisfactory as any other answer and mathematically defendable.
astronauts always go into the universe to search for life and also if we did not have any we would not know much about space
No life has been discovered on other planets yet. However, given the huge amount of planets in the Universe, and the fact that hardly any planet has been thoroughly investigated, it's quite possible that life does exist.
Currently, we don't know. So far we have never found any direct evidence of life beyond Earth. But, given the incomprehensibly large number of planets in the universe, many people think there probably is life elsewhere.
The answer to life, the universe and everything is 42.
An anthropic principle is any of several similar explanations for the nature of the universe, which state that either the universe is as it is because otherwise we wouldn't be able to observe it, or that the presence of intelligent life constrains the universe to its current form.
There is no reason to believe that the Universe will be "destroyed" - it will continue expanding, and at some point there won't be enough free energy left to support any type of life, but the Universe itself will continue existing.
