If you consider the universe one second after the Big Bang, the expansion rate would have to have been just right to an accuracy of 15 decimal places, or else the universe would really not work. — Alan Guth Copy Share Image
If one just tried to invent a universe on one's own, it would probably end up being a much less colorful and interesting universe… — Alan Guth Copy Share
Space is certainly something more complicated than the average person would probably realize. Space is not just an empty background in which things happen. — Alan Guth Copy Share
I am not aware of any sensible theory of how classical gravity could interact with quantum matter, and I can't imagine how such a… — Alan Guth Copy Share
My parents were not at all involved in science. In fact, neither of them went to college. — Alan Guth Copy Share
The idea of combining the physics of modern particle theory with cosmology was very young when I started working on cosmology. — Alan Guth Copy Share
It is rather fantastic to realize that the laws of physics can describe how everything was created in a random quantum fluctuation out of… — Alan Guth Copy Share
When one studies the properties of atoms, one found that the reality is far stranger than anybody would have invented in the form of… — Alan Guth Copy Share
If you bang two electrons together with enough energy, you produce protons. If there are no independent laws, then all the properties of protons… — Alan Guth Copy Share
The Big Bang theory says nothing about what banged, why it banged, or what happened before it banged. — Alan Guth Copy Share
The recent developments in cosmology strongly suggest that the universe may be the ultimate free lunch. — Alan Guth Copy Share
I think I always wanted to go into physics. What always fascinated me about science was the desire to understand what underlies it all,… — Alan Guth Copy Share
From a theoretical point of view, it is very hard to imagine how gravity could avoid being quantized. — Alan Guth Copy Share
