"In Search of the Big Bang" (brief review)

The big bang could not have started
as a mass singularity. If it did its
gravity would make it a black hole without any possibility of
expansion.

So do we take away gravity?
No. Because if we do we automtically
produce universal boudaries/an open
universe. Otherwise without gravity
the cosmology is one that violates
the No Boundary Proposal.

No gravity equals a violation of
the no boudary Proposal.

How do you like that?

So if you keep gravity and you don't
want a black hole the original matter
must be spread out. If it's spread out
it will not have a gravity so strong
as to not be able to expand/inflate.


In a high energy, low mass environment gravity is a non-effective force.
Current models of the universe give it around 10^-37 seconds before gravity
kicks in. This is a very long time.

Also, I thought big bang theory implied the universe began as a sea of
energy (photons?) which wouldn't have been affected (or have) gravity until
the other forces interacted enough to create objects with mass?
