W e also know how quantum fields generally work, and if inflation is a quantum field (which we strongly suspect it is), then there will always be more \u201cstill-inflating\u201d space out there. Whenever and wherever inflation ends, you get a hot Big Bang. If inflation and quantum field theory are both correct, a Multiverse is a must.<\/strong><\/p>\n<p>When we look out at the Universe today, it simultaneously tells us two stories about itself. One of those stories is written on the face of what the Universe looks like today, and includes the stars and galaxies we have, how they\u2019re clustered and how they move, and what ingredients they\u2019re made of. This is a relatively straightforward story, and one that we\u2019ve learned simply by observing the Universe we see.<\/p>\n<p>But the other story is how the Universe came to be the way it is today, and that\u2019s a story that requires a little more work to uncover. Sure, we can look at objects at great distances, and that tells us what the Universe was like in the distant past: when the light that\u2019s arriving today was first emitted. But we need to combine that with our theories of the Universe \u2014 the laws of physics within the framework of the Big Bang \u2014 to interpret what occurred in the past. When we do that, we see extraordinary evidence that our hot Big Bang was preceded and set up by a prior phase: cosmic inflation. But in order for inflation to give us a Universe consistent with what we observe, there\u2019s an unsettling appendage that comes along for the ride: a multiverse. Here\u2019s why physicists overwhelmingly claim that a multiverse must exist.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>One of the most successful theories of 20th century science is cosmic inflation, which preceded and set up the hot Big Bang.
