We should provide the meaning of the universe in the meaning of our own lives. So I think science doesn't necessarily have to get in the way of kind of spiritual fulfillment.

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection.

I cannot stress often enough that what science is all about is not proving things to be true but proving them to be false.

The real thing that physics tell us about the universe is that it's big, rare event happens all the time — including life — and that doesn't mean it's special.

The really important thing is learning how to sceptically question and rely on empirical evidence.

Philosophy used to be a field that had content, but then natural philosophy became physics, and physics has only continued to make inroads. Every time theres a leap in physics, it encroaches on these areas that philosophers have carefully sequestered away to themselves, and so then you have this natural resentment on the part of philosophers.

Metaphysical speculation is independent of the physical validity of the Big Bang itself and is irrelevant to our understanding of it.
