I enjoy Tyson’s enthusiasm but don’t accept the opening paragraph in his Cosmology for People in a Hurry:

In the beginning, nearly fourteen billion years ago, all the space and all the matter and all the energy of the known universe was contained in a volume less than one-trillionth the size of the period that ends this sentence.

Using the biggest hammer you have, try crushing a piece of gravel into so small a volume. Then, with another hammer, try crushing your first hammer into that same small volume.

Did he intend readers to accept it?

Is there a youtube for it?

I borrowed this book from my daughter who has a degree in microbiology and went to law school, and now works as an IT person. She bought it to read on a business trip with a couple of airport layovers. I enjoyed it, I can't say I understood all of it, but it laid things out very simply and logically. When I returned it to my daughter she says, "Oh yeah, I was wondering where that got to!"

I read the book last year, or the one previously. I highly recommend it!

Felt the same way after reading Hawking's book, A Brief History of Time. Completely frazzled brain.
