End of the universe?

We know NOTHING about the "end of the universe". We don't know if the universe WILL end, or what might cause this to happen, or what would come "after" the end of the universe, or even if the phrase "after the end of the universe" has any meaning at all.

There are some pretend "scientists" who can tell you, in amazing detail, what the "end of the universe" might look like. But no two of these actually agree, and all their guesses are based on shaky mathematical models which may (or may not!) have any relevance or accuracy.

Science is, to a very large degree, the study of our ignorance. We try to learn a little bit, but for every new fact we discover ten new questions, so our ignorance grows faster than our knowledge.
