Here is the second part.

When I heard about the seemingly spontaneous creation and destruction of particles, as described by this theory, I was immediately struck that this is probably related to the big bang. The universe as we know it, spontaneously created from nothing and eventually disappearing again, on a time scale unimaginable by we who popped up in the brief moment between.

I love that they covered this. The derivation of the Dirac equation is one of the masterpieces of modern physics and it rarely gets talked about.

Yeah if only I could find a straight up derivation... the spinor stuff is fairly simplistic I think most people would get it. I found the unification of electricity and magnetism, and although he wrote the equations down he didn't show how they are consistent, which was Maxwell's greatest feat.

BBC also did a beautiful piece on Boltzmann. It is a story many young physicists hear when taking Stat Mech. Often it is given as a warning that not only should we not take ourselves and work to seriously, but you should treat even the most bizarre ideas with respect.

They're probably not related at all since "before" the big bang, space and time didn't exist, which is not the case for spontaneous appearance of matter and antimatter pairs. Also, we have no theory that describes what happens at the time of the singularity, or "before" it, as opposed to QED.

Christ, who is the guy responsible for filling this video with 70% stock footage of stark looking landscapes or spacescapes that have nothing at all to do with the narrative. Can't be bothered to make diagrams that are actually related? I feel like this is a fluff piece that has scarcely advanced my actual understanding of the concepts, because it works at such a hand waving high level.

From the video "he had discovered particles of anti-matter"

Wouldn't positrons be "anti-energy" as they don't have any mass? - and if they follow the same rules as an electron - not quite a "particle".

Electrons (and positrons) have mass.

Yes, my mistake- I think my high school science is insufficient. And as they have mass, albeit a very tiny amount- I guess they are "matter" and not energy? >> ^rychan:

Energy has mass too, though it's probably more correct to say that mass and energy are equivalent.

It's a dupe... took me forever to find it:

Obviously, your Part 2 is also.

"All this sounds like science fiction..."

Am I the only one whose sick of hearing this used all the time in consumer level science programs?

No, you're not. This whole video is... wait a minute, I'm talking to a freaking robot. *ahem* Sounds like science fiction...
