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 brain weighs only three pounds, yet it is the most complex object in the solar system.

Science is definitely part of America's infrastructure, the engine of prosperity. And yet science is given almost no visibility in the media.

The best theory comes from string theory, which states that dark matter is nothing but a higher vibration of the string. We are, in some sense, the lowest octave of a vibrating string.

The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative.

The next big accelerator might be the ILC in Japan, a linear collider which might be able to probe the boundaries of string theory. So we physicists have to learn how to engage the public so that taxpayers money is used to explore the nature of the universe.

I agree, along with Carl Sagan, that we should eventually become a two planet species. Life is too precious to place on a single planet.
