This video starts playing again, ever time I refresh the page. That's getting old. What's up with that? Most embeds know to behave better.

Having now watched the video, one detail I'd like to pick on is that he gives Einstein too much credit for his cosmological constant. When Einstein was working on these equations, he came to the conclusion that the universe might expand forever, resulting in what we now think of as heat death. In a moment of weakness, or maybe some mild dishonesty, he included a constant that didn't relate to any known, measured force of the universe that, at some large scale, would act as a balancing force to hold the universe in order. He had no basis for its inclusion except for a fear of the implications of his own equations.
And so it was a supreme irony that decades later, it turned out that his constant was a real force in the universe, but, against his worst fears, it turned out to be NEGATIVE. There was in fact a cosmological constant representing the energy of empty space, but it served to blow the universe apart faster, rather than hold it together.
This isn't to step on Einstein, or his equations. It's just that this is what a little wishful thinking can sometimes bring you in the world of natural sciences.
Anyway, how do I watch part two of this lecture? This dumb player just loops the video when it gets to the end. Why can't they just use Youtube like everyone else?

I wasn't able to get to part 2 from the embed. It can be found here, however: http://www.themonthly.com.au/origin-universe-and-arrow-time-sean-carroll-2196

Thanks 'GrandArch'.
Ezra - man, don't leave us hanging dry; please provide fuller links.
Anyways, this lecture is fantastic to hear and watch; especially on Friday evening with a glass of fine wine...

"Anyway, you know what's weird? Time."
it is all an illusion
of our consciousness.
just try not to panic.
ride it through
like the ecstatic journey
that it is.
recognizing that we know nothing,
but
we can experience everything.
love seems to be embedded in the energy of creation.
even if it is just the love of creating.
