Summary

There's been lots of speculation in the popular press claiming the Big Bang never happened. Supposedly, new data from the James Webb Space Telescope presents a crisis for an old universe that emerged from a hot dense plasma, in favor of a much more ancient cosmology -- a plasma cosmology. Yet the underpinnings of the Big Bang are more solid than ever, thanks in large part to the fossil evidence astrophysicists have found of primordial nucleosynthesis, also called BBN. Join me for a deep-dive into the physics of the formation of the elements, perhaps the most indisputable evidence for the hot Big Bang there is. 00:00 Intro 00:01 Pillars of the Big Bang Theory 05:40 I meant to say hydrogen makes up 60-70% of the body by atoms, not by mass 08:00 Time vs. temperature in the early universe 10:00 Planck's Law 19:00 Deuterium 20:20 What does Neil think?

0:00.0	Any sufficiently advanced technology is indistinguishable from magic. Open the pod bay doors, please help.
0:16.0	Today's episode is going to take us way back,
0:21.0	back to the earliest fossils in the universe.
0:24.4	As I am an experimentalist, I love to do things in the laboratory
0:28.1	to explicate and explain the most interesting, fascinating,
0:32.2	and revealing features of our universe.
0:35.0	The Big Bang Theory is not just a wonderful TV show, it's also our closest held notion of how the universe
0:46.3	came to be, supplanting previous models such as the quasi steady state universe, the
0:51.1	static universe, and early versions of cyclical universes.
0:54.6	To ask a question as to why we have credulity or belief in this model, we have to look at the
1:00.0	pieces of evidence.
1:01.5	And there are three pillars, so-called pillars of the Big-Mang model
1:05.2	that we cosmologist adhere to and use in our daily work to gain more and more credulity in the
1:11.1	model itself and to also test it for its cracks, flaws, and foibles.
1:15.0	Those three pillars on which our modern cosmological model rests are the expansion of the universe, the Hubble expansion of every single galaxy with a
1:26.0	tiny handful of exceptions. 500 billion galaxies are all receding away from us. We want to be able
1:32.0	to explain that in a self-consistent coherent
1:35.0	conceptual framework. The origin of the primordial photons that I study called the
1:41.6	cosmic microwave background have to be explained and are explained in the context of a hot big bang.
1:47.0	And last but not least, a topic we haven't really touched upon in this channel, at least in the depth that we're going to go into today is called
1:54.2	b b b b b b b b b b bic nuclyosynthesis what does that mean well we know we're
1:59.6	made of matter we know there's a lot more non matter like us in the universe, so called dark matter.
