Big Bang Theory?

[bobthebandit]

If the Big Bang Theory is true in relation to the formation of the Universe, then why is every planet and star a perfect globe?
If the Universe started off with a massive explosion. then all the stars and planets should be jagged and uneven, much like the asteroids.

and they should all be flat on one side, where the big bang squidged them !

You're operating under the misconception that stars today are the same ones that formed about 200 million years after the inflationary period of the Big Bang (the Universe being somewhere near 14 billion years old. Very few if any Population III stars exist today...
Most planets including our Earth aren't a 'perfect sphere'. Fact is, the spheroid structure seen in all stars and planets are all due to gravitational forces...

Geez.
The Big Bang Theory posits an early universe of essentially homogenized, incredibly hot ,incredibly dense fundamental particles of matter in a highly energised state. From this, the Stars, the planets, the asteroids, are formed from a gradual decline in the energetic state of the early universe, with matter coalescing from the hot dense soup. Gravity then shapes the matter that forms, as more accretes around a central mass. Thats why Cosmic Background Radiation is important - Thats why the temperature gradients around the universe are important.

Every planet and Star is not a "perfect globe" - read Clanads answer - Earth, for example, is spheroidal, true, but it is not a "perfect globe".

The example you give bob, of a massive explosion, with all the stars and planets being violently outthrust,jagged fragments of some incredibly large mass is just wrong as any sort of description of what the Big Bang Theory actually is.

The others have covered it well above bob, I'd just like to add that the Big Bang theory is called that because it is a theory not a fact, not certain. It's the best explanation we have up to now, though no one can explain how and why it started.

The physical conditions prevailing at the 'time' of the big bang would have been so different from anything we could conceive of that our understanding of the local laws governing matter would not apply. Stars did not form until a long time after the big bang and are mostly gas.

The name 'Big Bang' is also somewhat misleading; the argument is that the origin of the universe was in a moment of very rapid matter expansion, not an explosion as the name suggests.
