| Apologies to Brian Wilson of The Beach Boys for mangling the line from "Don't Worry Baby" but Caltrops has a title limit.
I've been thinking about this for quite a while. Maybe my own ignorance makes me unable to see it, but here goes. A few weeks ago I saw an episode of a science show where they mention how the cniverse started with the big bang, then shortly thereafter - and in cosmic terms, "shortly thereafter" can mean anything from a billionth of a second, to a half an hour, to a month, a year or a couple million years - the universe cooled from several billion degrees down to several million, or something like that. I'm kind of wondering, "how"? If the universe was fairly tightly packed, or to the extent that it was a vacuum outside of it, how did it radiate the energy away? I mean, to transfer energy, as I see it, it has to radiate into something to dissipate heat. Maybe if you shine light out or something you can radiate a lot of heat, but I don't think you can release that much into pure vacuum, which is, by definition, an insulating material that doesn't absorb heat. Maybe I'm confusing heat with light or something, or ignoring the calculation of E=MC^2 that energy and matter are the same thing, in which case matter could have been expelled which would both use energy to expel the matter and use the energy as matter. Maybe that balances the equation that I'm misunderstanding. But somehow it seems like someone's left something off to explain how the universe was able to cool itself down as quickly as it is claimed it did. As hot as it was after the big bang, to put it bluntly, cooling it down meant disposing of a lot of energy, I mean, a lot, "that's a lot of fuckin' energy, man!" |
