The trouble with "books" is....... one author say one thing and another says something else.

They don't say the same thing in different ways either.

If, as some hypothesise, everything "cancels" everything out, the Universe does not therefore exist.

Clearly that can't be true because we're here.........

Sooooooo, if things are not "cancelled out", it all wasn't made out of nothing and things cannot therefore return to nothing (again).

The whole thing needs a re-think by people not influenced by anything that's gone before.

We have dark matter, dark energy and I saw somewhere we have exotic matter and exotic energy? Really? Whatever next?
