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

What science is all about is a process. It's like saying, "Well, is it important for people to know that World War II happened?" Well it's part of what makes us who we are. And so, there's basic bits of science we need to know.

The fact is that people would rather cling when they're afraid of something to a priori beliefs than rather open their minds about it.

The ultimate goal of physicists is to arrive at an equation that explains everything and could fit on a t-shirt. That may happen but the t-shirt would have to be 10-dimensional.

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.

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