Baby Universe: speculations and shortcomings

Posted on | May 14, 2010 | No Comments

A recent conversation with a friend:

R: Okay, I just heard that some of your co-workers are claiming to be able to see evidence of ‘the time before the Big Bang.’ I think you should go see them, and, in your authority as the oldest employee at Goddard, to knock it off. Things are confusing enough as it is.

B: I suspect there are some problems with the definition of “Big Bang” in such statements. If the Big Bang is considered to be the beginning of the Universe, then they or the reporters who are reporting it should indeed Knock It OFF! If, however the Big Bang is the period of Inflation that supposedly happened a split second after the beginning of the Universe, then there is a chance something can be figured out about that time before the Bang, though actually “seeing” it may be a bit of a conceit.

R: Speaking of the Big Bang, and waffling around it, there’s a similar issue emerging in deep-time geology. Lately I’ve been trying to study more about the early history of Earth, the Hadean Eon and all that, and I notice that there is a tendency to start Earth history at the point the moon was created, supposedly by a collision with a big, big planetoid named (By whom? Why wasn’t I consulted?) Theia. What if I want to hear about before that?
It’s like the big bang not really being the Big Bang.

B: It seems likely that anything large enough to generate the moon from an Earth collision probably would fundamentally change the evolution/history path of the Earth. So maybe it will never be possible to do anything but speculate on what the Earth was like as a baby. Either that or it was a pretty dull place before Theia arrived…
There has been a lot of theory and research done on solar system and planet birth, but not much on Plant/Planetoid collision. Sounds like a good place to start or climax a story….
