The sea is one of the most beautiful and yet dangerous places on the face of the earth for human beings. Oceans of fascination which have been instrumental in human civilisation by both denying people the ability to cross them and then allowing them too. Like so much on Earth this duality appears to be fundamental to how we experience life.
Astronomers and cosmologists are attempting to understanding the universe in terms that bring everything down to a single theory and it may be that this is what mathematics leads us to look for, but is not actually what the universe is like. Mathematics is a brilliant tool but it is still just a tool that opens up understanding and we should use our understanding in more expressive and wide-ranging ways. Getting the universe we see to work inside our mathematical formulae without allowing those formulae to evolve to include two answers might be distracting.
I say this because observations are opening up a series of unknowns in dark matter,dark energy, dark flow which do not seem to fit easily with what we know about how the Big Bang, being an explosion, should have produced.
Maybe there is more than one kind of explosion. Maybe at those temperatures and those masses, explosion isn’t even a viable term. Maybe imagination and mathematics have to work together as two sides of the same equation to resolve the problem.
