00:00Well, the Big Bang Theory doesn't explain how the universe got to that initial hot, dense state.
00:05It just describes what happens after that.
00:08Inflation, on the other hand, describes how the universe got from being smaller than an atom to being larger than
00:15we can currently observe.
00:17So the Big Bang Theory and inflationary models work together to explain how the universe evolved from a hot, dense
00:24state to the complex web of galaxies and galaxy clusters we see today.
00:28But while the Big Bang and inflation are supported by a lot of evidence, they don't necessarily paint the complete
00:36picture.
00:37Many scientists hypothesize that these models are incomplete and will eventually be replaced by something that explains the beginning of
00:46the universe and the mechanism behind inflation.
00:48So while the Big Bang might not have been a literal explosion, it's still a pretty dramatic event, whether it
00:55was caused by a quantum fluctuation, a collision with another universe, or something else entirely.
01:02Either way, we can be grateful that whoever named it didn't go with a more scientific term, the Great Filter.
01:09Scientists continue to refine their models of the Big Bang and inflation, but they've made some key predictions that can
01:17be tested with current and future experiments.
01:19For example, one prediction of inflation is that there should be some particles moving through space with a specific pattern
01:27of motion.
01:28If scientists can spot these particles, known as a stochastic gravitational wave background, it would provide strong evidence for inflation.
01:37Another prediction of inflation is that there should be some distortions in the CMB caused by the stretching of space
01:45-time during the rapid expansion.
01:48While scientists haven't detected these distortions yet,
01:51However, there are었 many different dimensions where the Philadelphia light can be used to be some sort ofி
01:51or stronger people in the mathematical experiment.
