What is the Big Bang theory?

Explain the theory and the evidence scientists use to support the theory. Please nothing about the show..

Apparently we have some non funny people on here. It's the theory that involves the building blocks of the existence of everything. The "creator" if you will....the reason the universe (known) is expanding. The proof is in the "echoes" astronomers can hear and see from the remnants of the explosion..actually the Big Repel.

See what happens when you tell people "... and don't say such n' such ..." The theory goes that everything in the universe was compressed into one tiny point and exploded out. That's why the universe is still expanding.

Look it up, you learn more when you do your own research. You'll retain it better for the test.

It's kinda dumb/funny but it shows us what's gonna happen if we keep going the way we are. It takes place in the future and everybody is a complete moron haha

Your all wrong! It is not scientifically a comedy it is the theory that all matter was started from one huge explosion.

explosion of what? exactly ?
Report as
Tiny little atomic structures
Report as
It wasn't an explosion, it was more of an expansion, like an inflating balloon.
Report as
I've never heard of an "atomic structure" is that bigger than an atom or smaller or something else entirely?

A ball of energy that exploded and created the universe pretty much. Evidence: the way a star forms

it was thought to be the beginning of our galaxy. I don't know specific details but I do know that it was when two things collided to make a big bang. Therefor creating the planets and the sun. Hope this helped :)

Once it was realized that the universe was expanding faster and faster, physicists did the math backwards, as if the universe was shrinking slower and slower, and discovered that (apparently) at one point the universe just burst out of one particular point and began to "inflate". (The scientists' word, not mine.) Someone tried making fun of the theory by calling it the Big Bang Theory and the name stuck.
It never made sense to me, and a few physicists have admitted that it doesn't make sense to them either (the something out of nothing part) but so far they haven't found any other information.
If they run the information they do have (the expanding universe and its speed) back to a beginning, the Big Bang is what they get.

the theory that all matter and energy in the universe was compressed into an extremely small volume that 13-15 billion years ago exploded and began expanding in all directions
evidence that supports it is the big bang theory is the only theory that explains the following
1. The galaxies (or galaxy clusters) are systematically moving away from us such that the farther away galaxies are moving faster away from us. As a result of General Relativity this means that space itself is expanding carrying the galaxies with it. Both the Big Bang Theory and its major competitor, the Steady State Theory, could explain it. Recall that the Steady State Theory used the perfect cosmological principle while the Big Bang uses the cosmological principle.
2. The cosmic microwave background radiation can be explained only by the Big Bang theory. The background radiation is the relic of an early hot universe. The Steady State theory could not explain the background radiation, and so fell into disfavor.
- ill post another addition it has too many characters (in comments)

3. The amount of activity (active galaxies, quasars, collisions) was greater in the past than now. This shows that the universe does evolve (change) with time. The Steady State theory says that the universe should remain the same with time, so once again, it does not work.
The number of quasars drops off for very large redshifts (redshifts greater than about 50% of the speed of light). The Hubble Law says that these are for large look-back times. This observation is taken to mean that the universe was not old enough to produce quasars at those large redshifts. The universe did have a beginning.
4. The observed abundance of hydrogen, helium, deuterium, lithium agrees with that predicted by the Big Bang theory. The abundances are checked from the spectra of the oldest stars and gas clouds which are made from unprocessed, primitive material. Even better observations are those made of light from very distant quasars that have passed through gas in regions of the universe where are no stars that could have contaminated the gas. The intervening intergalactic primordial gas imprints its signature on the quasar light giving us the composition of the primordial gas. All of those places have the predicted relative abundances.

A giant space explosion that I really have no idea how it happened. Apparently it created the universe...
It's also a funny show. 3:)

What the universe today originated from a point?nothing was out there and the classical physics was out of operation?.what existed was an effect called The Quantum Fluctuation.which means that the energy can be parted into two parts?the negative energy and the positive energy . The positive energy gradually formed the positive matter ?E=MC2?........and become what you have seen now .
