Relativity can, for instance, explain that the universe had once been clumped into a dense fireball. But it can never explain how matter actually behaved. Alan Guth More Quotes by Alan Guth More Quotes From Alan Guth The Big Bang theory says nothing about what banged, why it banged, or what happened before it banged. Alan Guth bangs bigs theory The question of the origin of the matter in the universe is no longer thought to be beyond the range of science - everything can be created from nothing. It is fair to say that the universe is the ultimate free lunch. Alan Guth range lunch matter 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 realizing space average Despite its name, the big bang theory is not really a theory of a bang at all. It is really only a theory of the aftermath of a bang. Alan Guth aftermath bangs names It’s hard to build models of inflation that don't lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously. Alan Guth pushing ideas thinking It's actually safe to create a universe in your basement. Alan Guth basements universe safe In the context of general relativity, space almost is a substance. It can bend and twist and stretch, and probably the best way to think about space is to just kind of imagine a big piece of rubber that you can pull and twist and bend. Alan Guth twists space thinking The recent developments in cosmology strongly suggest that the universe may be the ultimate free lunch. Alan Guth lunch development may It is rather fantastic to realize that the laws of physics can describe how everything was created in a random quantum fluctuation out of nothing, and how over the course of 15 billion years, matter could organize in such complex ways that we have human beings sitting here, talking, doing things intentionally. Alan Guth random nothing sitting matter If we assume there is no maximum possible entropy for the universe, then any state can be a state of low entropy. Alan Guth low possible entropy universe To a theoretical physicist, there is no greater joy than to see that this curious activity we call calculation - the depositing of ink on paper, followed by throwing away the paper and depositing new ink on more paper - can actually tell us something about reality. Alan Guth new see joy reality Now, what space ultimately is - I should confess, I think most physicists believe - we don't yet know. Alan Guth think know space believe Our best theory of describing space at a fundamental level is probably string theory. Alan Guth level best space theory When one studies the properties of atoms, one found that the reality is far stranger than anybody would have invented in the form of fiction. Particles really do have the possibility of, in some sense, being in more than one place at one time. Alan Guth place being time reality My parents were not at all involved in science. In fact, neither of them went to college. Alan Guth fact parents college science I had considered MIT a place where brilliant people came. Alan Guth place where brilliant people In high school, I was the best broad jumper on our team, and I kind of thought that when I got to MIT, I'd probably still be the best broad jumper, 'cause why do broad jumpers come to MIT? But it turned out to actually be the other way around. There was another person in my class who could jump about 3 feet further than I could. Alan Guth best team way school 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 big you universe work It's not a coincidence that the Bible starts with Genesis. Most people really want to know where we came from and where everything around us came from. I like to strongly push the scientific answer. We have evidence. We no longer have to rely on stories we were told when we were young. Alan Guth push know bible people If you bang two electrons together with enough energy, you produce protons. If there are no independent laws, then all the properties of protons must somehow be 'known' by the electrons. By extension, every elementary particle must carry around enough information to produce the entire universe. I find that difficult to believe. Alan Guth you universe together believe
