The more the universe seems comprehensible, the more it also seems pointless.

My advice is to go for the messes - that's where the action is.

Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough.

The invisible and the non-existent look very much alike.

It is even harder to realize that this present universe has evolved from an unspeakably unfamiliar early condition, and faces a future extinction of endless cold or intolerable heat. The more the universe seems comprehensible, the more it seems pointless.

The whole history of the last thousands of years has been a history of religious persecutions and wars, pogroms, jihads, crusades. I find it all very regrettable, to say the least.

In our universe we are tuned into the frequency that corresponds to physical reality. But there are an infinite number of parallel realities coexisting with us in the same room, although we cannot tune into them.
