Stephen Hawking

The universe is not a cold concept. It is a hot concept.

The universe is not a dark concept. It is a bright concept.

The universe is not an empty concept. It is a full concept.

The universe is not a simple idea. It is a complex idea.

The universe is not a static idea. It is an evolving idea.

The universe is not a friendly idea. It is a dangerous idea.

The universe is not a predictable idea. It is an unpredictable idea.

The universe is not a boring idea. It is an exciting idea.

The universe is not a small idea. It is a vast idea.

The universe is not a young idea. It is an old idea.

The universe is not a perfect idea. It is an imperfect idea.

The universe is not a silent idea. It is a noisy idea.

The universe is not a cold idea. It is a hot idea.

I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

The universe does not behave according to our preconceived notions. It continues to surprise us.

If time travel is possible, where are the tourists from the future?

Quiet people have the loudest minds.

One of the basic rules of the universe is that nothing is perfect. Perfection simply doesn't exist... Without imperfection, neither you nor I would exist.

We are each free to believe what we want and it is my view that the simplest explanation is there is no God. No one created the universe and no one directs our fate.

I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken-down computers; that is a fairy story for people afraid of the dark.
