Where you come from

I am sure you will want to know this. Violent cosmic events have produced the material for your flesh and bones. In the future we will have graphs showing what dark energy is (if it exists) and what black holes produce (if anything, besides gravity waves).

For myself I do not think that any currently accepted view of the universe – Big Bang, cosmic inflation, dark matter, dark energy, string theory – will survive the next century intact. I say this not because I have doubts or special insights about the contemporary theoretical picture, but because we have gone through several revolutions of cosmology since the 1400s, and we will go through more.
