It’s actually safe to create a universe in your basement.
ALAN GUTHIt’s actually safe to create a universe in your basement.
ALAN GUTHThe question of the origin of the matter in the universe is no longer thought to be beyond the range of science.
ALAN GUTHBut most models of inflation do lead to a multiverse.
ALAN GUTHIt is really only a theory of the aftermath of a bang.
ALAN GUTHIn the context of general relativity, space almost is a substance.
ALAN GUTHSpace is certainly something more complicated than the average person would probably realize.
ALAN GUTHThe Big Bang theory says nothing about what banged.
ALAN GUTHIt is fair to say that the universe is the ultimate free lunch.
ALAN GUTHThe recent developments in cosmology strongly suggest that the universe may be the ultimate free lunch.
ALAN GUTHEverything can be created from nothing.
ALAN GUTHWhy it banged, or what happened before it banged.
ALAN GUTHSpace is not just an empty background in which things happen.
ALAN GUTHAnd evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously.
ALAN GUTHDespite its name, the big bang theory is not really a theory of a bang at all.
ALAN GUTHIt’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.
ALAN GUTHIt 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.
