If one just tried to invent a universe on one's own, it would probably end up being a much less colorful and…

Space is certainly something more complicated than the average person would probably realize. Space is not just an empty background in which…

— Alan Guth

I am not aware of any sensible theory of how classical gravity could interact with quantum matter, and I can't imagine how…

My parents were not at all involved in science. In fact, neither of them went to college.

— Alan Guth

The idea of combining the physics of modern particle theory with cosmology was very young when I started working on cosmology.

— Alan Guth

It is rather fantastic to realize that the laws of physics can describe how everything was created in a random quantum fluctuation…

Reformed Jews don't have to quite believe in God.

— Alan Guth

When one studies the properties of atoms, one found that the reality is far stranger than anybody would have invented in the…

If you bang two electrons together with enough energy, you produce protons. If there are no independent laws, then all the properties…

— Alan Guth

The Big Bang theory says nothing about what banged, why it banged, or what happened before it banged.

— Alan Guth

The recent developments in cosmology strongly suggest that the universe may be the ultimate free lunch.

— Alan Guth

It's actually safe to create a universe in your basement.

— Alan Guth

I think I always wanted to go into physics. What always fascinated me about science was the desire to understand what underlies…

— Alan Guth

From a theoretical point of view, it is very hard to imagine how gravity could avoid being quantized.

— Alan Guth

I'm pretty slow at writing papers.

— Alan Guth

I had considered MIT a place where brilliant people came.

— Alan Guth

To a theoretical physicist, there is no greater joy than to see that this curious activity we call calculation - the depositing…

— Alan Guth

It was sort of assumed, from the time I was born, really, that I would go to college. That's sort of the…

If we assume there is no maximum possible entropy for the universe, then any state can be a state of low entropy.

— Alan Guth

Our best theory of describing space at a fundamental level is probably string theory.

— Alan Guth

Now, what space ultimately is - I should confess, I think most physicists believe - we don't yet know.

— Alan Guth

We don't have a solid theory of how the universe originated, but that doesn't mean we have to invoke a deity.

— Alan Guth

If there's no limit to how big the entropy can get, then you can start anywhere, and from that starting point, you'd…

— Alan Guth

In the context of general relativity, space almost is a substance. It can bend and twist and stretch, and probably the best…

If you consider the universe one second after the Big Bang, the expansion rate would have to have been just right to…
