This Proves the Big Bang Happened: 30 Minute Thesis (#251)

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
