Can you explain the big bang theory in simple terms?

Question

Nothing silly like bang and the world was made...

Answer 1

Gaseous explosion, a mixing of gases, a collision of gases and after a eons of time life.

In our world it happens much quicker and much simpler.

Place a bowl of tap water in your garden, after 3 days you will see life in it.

Answer 2

BANG LOUD NOISE. TRUTH GOD MADE THE WORLD

Answer 3

I will explain you what big bang theory means;

1) Big bang started from a hyperdense high energy area. But still big bang  is the beginning of everything not the high energy dense area.  Y started from X but X didnot give rise to Y. Joke agree? Big bang people are telling like this; they borned to their fathers, but their fathers are not their fathers, lol lol lol

2) Big bang started from an Infinite area condensed into small area. However the infinite source of big bang gave rise to a finite universe.  (big bang people say universe is finite).

X was infinite, the whole X becomes Y, now Y is finite. You had 10 dollars. You spend the whole 10 dollars and buy a stuff. So the stuff costed you 10 dollars, but according to big bang proponents the stuff costed 2 cents. Joke, agree? How can an infinite high energy dense area give rise to finite universe???

3) Big bang people say that the universe is finite but un bound. They say there may be 11 dimensions to explain it.  Why not 2.33 dimensions? why not 6 divided by 3 multiplied 8.1 dimensions? from where they are getting all these ideas of 11 dimensions ??? There is no physics theory as of now tells that a finite object can be unbound.

4) How can scientists know already that nothing existed before big bang. How can they already know that nothing exists out side the observable universe??

Big bang theory does explain certain things around us. There are certain evidence that universe is expanding etc. But it doesnot mean the universe started from big bang. May be this universe what we see around us started from big bang. But universe must have always existed in one or other forms.

Do you really belive that the big universe started from nothing??  At least that is what big bang jokers are telling. They think before big bang there was nothing.

They want us to believe this stuupiid joke.

It is arrogant thinking by them to say that everything started from big bang.

Answer 4

The overall Big Bang theory states that the universe started from an incredibly dense singularity that exploded. All matter, light and energy came from that explosion. The size of the universe increases as everything expands from this explosion. The theory is that of an expanding universe, meaning that the universe as a whole is expanding, instead of a static universe meaning that matter is expanding into a statically sized space. The theory states that the size of the universe is equal to the speed of light (the item furthest away from the explosion as possible) times the age of the explosion. In simpler terms, the light created from the explosion is expanding in equal directions and they represent the edge of the universe.

Answer 5

It's basically a plot device.

Answer 6

the whole universe was in one hot dense state called a singularity, whereby the whole universe was in one point, this "explosion" or "big bang"sent out all matter,and is now expanding.

Answer 7

It is rather beyond our comprehension, to try to understand a time before space, before matter, dammmit, before time!  We shall forever be dogs barking at the passengers of air-balloons, unable to understand what we are experiencing.

Answer 8

all that exist was once concentrated into a hyperdense single poin. heat buildup made the concentrated universe expand in a grand explosion that releases all the matter and energy that makes up everithing in the Universe.

Answer 9

KaBOOOOM!

Answer 10

there's a fine line between a simple explanation and a wrong explanation. the big bang is not really a simple thing.

having said that though, a long time ago the universe was filled with a hot gas (technically, plasma) much like you might find below the surface of the sun. stuff happened before that, but let's ignore that for now. the universe expanded and cooled to the point where it became transparent to light. again the surface of the sun is a good analogy for this. the interior of the sun is opaque to light for much the same reason that the early universe was. now the universe continued to expand and cool, and small ripples in the plasma clumped together and formed galaxies, stars, and eventually planets. now we can see the light from the distant early universe which is just now reaching us, and we can see that distant galaxies are speeding away from us just as if the universe was still expanding (probably because it is!).

now you might wonder why the universe was expanding to start with. well it turns out that the equations that govern this (derived from general relativity) show that what we might think of as the 'natural' situation, a static universe that doesn't expand or contract, can only occur if the density of matter and energy in the universe is balanced just right. well things are not balanced just right, so the universe expands.

what happened before the hot plasma stage? there are a few ideas but I think that's where simple answers are really going to be wrong answers.

hope that helps.

Answer 11

BOOM!!! (then the universe happend)

Answer 12

bang we r  here

Answer 13

The Universe started out very hot and dense.  It was not a point, but the part of the Universe that is now the visible universe started out about the size of a proton (very small).  But the Universe must have been at least the size of our current Universe when it started.  It's absurdly big now - at least 150,000,000,000 light years across.

As the Universe expanded, it cooled.  The hot dense stuff became everything we experience today.  It has taken about 14,000,000,000 years to get to where we are now.

Answer 14

In the Big Bang, our Universe (which includes space, time and matter) was created out of a singularity - an infinitely small point of infinite density and temperature.

That's the simplest summary. If you want to know more, have a look at the Wikipedia article

Answer 15

I think it was big big BIG clumps of stones in space colliding and breaking up and forming the planets?

Answer 16

the universe collapsed back on itself into a final singularity,The entire universe into a single dense point and BOOM the whole universe is recreated anew,Expanding outward forming galaxies and stars etc  until it finally collapses back in on itself and on and on. NEVER ENDING CYCLE.

Answer 17

The Big Bang theory is a theory of how the universe was formed. It all began as a few molecules flying around in nowhere

such as protons, neutrons and electrons then something happened that forced them to get together in one single spot and once they did, booom, the Big Bang exploded, spreading the molecules and gasses for miles. These molecules had later became galaxies, stars, and planets. So through millions and millions of years, our universe was expending and it's still expending today.

Answer 18

First there was NOTHING. Then from a single point a BANG and everything in our Universe was created. From the BIG BANG it expands outward, into nothingness. In the Universe elements bumped together and created stars (like our Sun) and planets.  Giant gas clouds in space (in our Universe) are still making stars, and planets too. It is figured that 90% of the mass (think weight) of the Universe is still dust (and gasses). We don't know if it keeps growing forever, or if at some time it will start to collapse back into it's self (the Universe).  SO even to believe in the BIG BANG THEORY, you still have to believe in something (everything) coming from nothing.
