- Richard P. Feynman99◆ What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.
- Richard P. Feynman99◆ The role played by time at the beginning of the universe is, I believe, the final key to removing the need for a Grand Designer, and revealing how the universe created itself. … Time itself must come to a stop. You can't get to a time before the big bang, because there was no time before the big bang. We have finally found something that does not have a cause because there was no time for a cause to exist in. For me this means there is no possibility of a creator because there is no time for a creator to have existed. Since time itself began at the moment of the Big Bang, it was an event that could not have been caused or created by anyone or anything. … So when people ask me if a god created the universe, I tell them the question itself makes no sense. Time didn't exist before the Big Bang, so there is no time for God to make the universe in. It's like asking for directions to the edge of the Earth. The Earth is a sphere. It does not have an edge, so looking for it is a futile exercise.
- Stephen Hawking99◆ Not only is the Universe stranger than we think, it is stranger than we can think.
- Werner Heisenberg99◆ It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.
- Michio Kaku99◆ The only thing known to go faster than ordinary light is monarchy, according to the philosopher Ly Tin Wheedle. He reasoned like this: you can't have more than one king, and tradition demands that there is no gap between kings, so when a king dies the succession must therefore pass to the heir instantaneously. Presumably, he said, there must be some elementary particles -- kingons, or possibly queons -- that do this job, but of course succession sometimes fails if, in mid-flight, they strike an anti-particle, or republicon. His ambitious plans to use his discovery to send messages, involving the careful torturing of a small king in order to modulate the signal, were never fully expanded because, at that point, the bar closed.
- Terry Pratchett99◆ Nonsense is that which does not fit into the prearranged patterns which we have superimposed on reality...Nonsense is nonsense only when we have not yet found that point of view from which it makes sense.
- Gary Zukav99◆ Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness.
- Bill Bryson99◆ What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary.
- Stephen Hawking99◆ The release of atomic power has changed everything except our way of thinking ... the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker. (1945)
- Albert Einstein99◆ I remember discussions with Bohr which went through many hours till very late at night and ended almost in despair; and when at the end of the discussion I went alone for a walk in the neighbouring park I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?
- Werner Heisenberg99◆ Energy is neither created nor destroyed. It just changes shape.
- Sheri Reynolds99◆ How wonderful that we have met with a paradox. Now we have some hope of making progress.
- Niels Bohr99◆ Those who are not shocked when they first come across quantum theory cannot possibly have understood it.
- Niels Bohr99◆ Not only is the universe stranger than we imagine - it is stranger than we can imagine.
- Arthur Stanley Eddington99
