what other theories besides the big bang theory are there?

Question

what theories are there besides the big bang? What are some uncommon theories?

Answer 1

That pretty much is the only scientific way to explain the begining of the universe. There are dozens of modifications to it, mainly dealing with the mechanisms of expansion/contraction or what cause it, but it always comes back to the big bang.

Answer 2

Well, if you mean scientific theories (e.g. excluding religious creation stories, which I suppose you could include if you wanted to but which don't have much science behind them), then the big bang is more or less it today. Some people have mentioned the steady state theory, but that went out the window in the late 1920's with Hubble's observation that pretty much all galaxies are moving away from each other. Einstein was a supporter of the steady state theory early on and in order to make the steady state theory work he inserted what is called the "cosmological constant" into his general theory of relativity. When Hubble's results came out, he felt much the fool, and called it the greatest mistake of his life (though, ironically, the cosmological constant has been getting lots of attention over the past few years for reasons I'll try to go into in a bit).

The big bang theory itself is basically the statement that as all the galaxies are more or less moving away from each other, that this implies that at some point in the past all the universe was "at the same place", from which it expanded into the universe we know today. This is the essence of the big bang theory.

However, the devil is in the details, and there are several specific things which we haven't pinned down. There are issues like dark matter, the fact that the universe's density is very, *very* near a critical density (too close to be called coincidence), and the more recently discovered fact that the universe's expansion is accelerating (e.g. not only are galaxies moving away from us, the speed with which they are is increasing, and not slowing down due to gravitational attraction). One interesting thing about this last issue is that Einstein's cosmological constant does a pretty decent job of describing this, so what in 1996 was a quaint footnote in the history of modern physics by 2006 is a serious point of discussion and investigation.

As there are several outstanding issues, there are various proposals for solving or addressing these issues, either separately or together. But, as we haven't nailed this down, you can look at all this as resulting in the existence of various competing versions of the big bang theory which differ in the details. But the key idea of every one of these theories is basically the same in that the universe began with some kind of big bang, and has been expanding ever since. The details differ, somewhat, though.

Answer 3

In cosmology, the steady state theory (also known as the Infinite Universe Theory or continuous creation) is a model developed to challenge the big bang theory. In steady state it was propose that matter was formed from nothing, when the universe expanding there by accounting for the formation of mass. The steady state also propose that the universe began from nothing and it didn't have an ending; Einstein was a huge supporter of this theory.

the steady state theory became obsolete when the back round microwave radiation was discovered ie( the radiation that occur during the Bing bang)

Answer 4

The universe expanding is not another theory that is competing with the big bang, we KNOW the universe is expanding. As far as the begining of the universe, I think the only scientific theory is the Big Bang.

Answer 5

Most astronomers believe the debate is over regarding the big bang, the current frontier is what happend prior to the big bang and will there be a big crunch. Then there's the black holes, dark matter, and other lessor phenomena thats keeping them busy. I don't think you're asking about the old geocentric world views, are you?

Answer 6

There are a few theories, none of which make very much sense, but you asked!

1)The universe has been here forever- it was created by God @ the beginning of time

actually... that's all I've got.

Answer 7

EVERY THING IS MADE FOR A PURPOSE.

BULBS FOR LIGHTS FOR PLACES.

AUTOMOBILES FOR TRANSPORTATION.

TREES GIVE OFF OXYGEN.

THE GROUND TO WALK ON.

THE MOON AND STARS TO LIGHT UP THE NIGHTS.

THE CLOUDS DECORATE THE SKIES.

HANDS MADE TO WORK.

WHO HAVE DONE ALL THESE WONDERFUL THINGS?

THE BIG BANG COULD NEVER MAKE THINGS AS THEY ARE.

THE BIG BANG IS A THEORY THAT SAYS TO THE HUMAN MIND I DONT KNOW SO THE BIG BANG IS JUST SOMETHING ELSE TO TRY TO SATISFY THE HUMAN MIND.

AN INTELLIGENT DESIGNER IS YOUR ONLY ANSWER FOR THE IMPOSSIBLE.
AN ALL POWERFUL BEING. THE FATHER, THE SON, AND THE HOLY SPIRIT. BLESSED BE THE LORD! AMEN.

Answer 8

Nope! No theories, no more theories, no more balonies, for men of truth KNOW the Powers to Create The All and The Entire, for a time endless, and a dimension endless was all done in one miniscule of time, from eternity to eternity. thanks.

Answer 9

type the words 'miracles of islam' and watch the videos in english well explained. internet.

Answer 10

im pretty sure one other theory is the EXPANDING UNIVERSE THEORY. (im almost (almost) positive) hey look, double parethesis!!!


(hey, i only learned about it last year guys, stop bein all rawr about it, gosh!)
