It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.

When I get bored, or get stuck on an equation, I like to go ice skating, but it makes you forget your problem. Then you can tackle the problem with a fresh new insight. Einstein liked to play the violin to relax. Every physicist likes to have a past time. Mine is ice skating.

I often think that we are like the carp swimming contentedly in that pond. We live out our lives in our own "pond," confident that our universe consists of only the familiar and the visible. We smugly refuse to admit that parallel universes or dimensions can exist next to ours, just beyond our grasp. If our scientists invent concepts like forces, it is only because they cannot visualize the invisible vibrations that fill the empty space around us. Some scientists sneer at the mention of higher dimensions because they cannot be conveniently measured in the laboratory.

If you could meet your grandkids as elderly citizens in the year 2100 … you would view them as being, basically, Greek gods… that's where we're headed.

Well, Congress gave us a billion dollars to dig the hole, this gigantic hole. Bigger, much bigger than the hole in Geneva, Switzerland. Then they canceled the machine and gave us a second billion dollars to fill up the hole. Two billion dollars to dig a hole and fill it up. That is the wisdom of the United States Congress and it really makes you wonder: Is there intelligent life on the Earth? Certainly not in the United States Congress.

The most likely possibility, favored by current data, is that the universe will die in Ice, not Fire. However, personally I believe that trillions of years from now, we (if we are still around) will have the technology to leave the universe, perhaps in an interdimensional life boat, and move to a warmer universe.

God throws dice, what can I say?
