Big-Bang Theory- New Idea on it

I have been pondering something for a while now, and it is how the "stuff" in the universe came out. Mostly, just whether or not galaxies came out preformed or, like planets, coalesced into their current selves. If researchers believe that galaxies came out preformed (which i suspect they dont), then this might make sense.

Nothing ever seems to come out preformed in nature, including planets, animals (evolution), stars, etc.
What I'm going for is that, black holes and all the stellar dust and gas was thrown out indiscrimately into space, and the black holes began to "suck up" the gas and dust, creating a whirlwind effect with the gas, much like a drain in a sink does when filled with water.

Am I way off the mark?:frown:

Actually, the formation of galaxies and planets are two of the most active areas of study in astronomy right now. We're pretty sure they didn't just "come out" with the universe... we think they gradually formed by a combination of gravitational and electromagnetic interactions.

There are some theories that say there should have been black holes formed very early in the history of the universe, but these theories are quite uncertain at this point. The accretion of gas and dust onto a black hole does, we believe, occur in a disk structure, sort of like the whirlpool you describe. However, black holes don't "suck" you towards them anymore than the earth does. They attract by the same mechanism -- gravity. That means one can just as easily be in orbit around a black hole as they can be around our sun.

In fact the 'primordial black hole' conjecture by Stephen Hawking has been pretty much ruled out by measurements of the cosmic gamma ray background. One of the most puzzling questions in modern cosmology is how structures like galaxies formed so rapidly after the big bang. It is extraordinarily difficult to explain this without a boatload of dark matter in the early universe - which also helps explain why cosmologists are so fond of the LCDM model.

Those particular measurements only rule out an abundant population of very low-mass black holes (the strongest Hawking radiators).

Correction noted and agreed. Albeit, I don't recall Hawking having modeled super massive black hole formation in the early universe. No big deal. The lack of mini PBH's mostly creates headaches for accretion models.

I'm not familiar with Hawking's work specifically, but primordial black hole formation can occur over a wide range of masses. The gamma-ray background only rules out those around 1015 grams.

Ahh, I see. Thanks for the timely response and good explanation.
