Can someone explain the big bang theory to me?

Question

also, try not to give any links, and don't use any big terminology a 13 year old wouldn't understand.

All i know is that earth is a chunk of blown up something else.

also, can you answer a few questions?
1. If the big bang, was in fact an explosion, how did earth come to be around 80% water?
2. If the original thing that earth was from was a star, aren't stars balls of gas, therefore, earth can't be...well, earth?
3. Of course everything on earth that is existing now wasn't existant before....so is evolution really that complicated and advanced?

o. thanks. but about the water. heh. i forgot that it's COVERED, not made of. but still, where did that portion of water come from?

Answer 1

Thanks for asking this. I've watched several specials on the Big Bang, and I know tons about it.

Don't think of the Big Bang as an explosion. Think of it as more of a creation of energy. Here's what happened:

First, there was nothing. Then, for no apparent reason, a spec appeared. That spec was hotter than...well, anything. It had, in that tiny point, all the energy of the Universe. So, it expanded. Really fast. It pretty much blew up, and in three seconds was HUGE.

So now you got all this energy. Well, as you might know, energy can be turned into mass, and mass can be turned into energy. (Mass is matter if you didn't know). A great portion of that energy "condensed" and became matter. So about 300,000 years after the Big Bang, there were huge clouds of Hydrogen floating around. These are called nebulas.

These nebulas "collapsed". That means that the gas clumped together, creating gravity (which is an attraction between objects with mass). So now you have a cloud of hydrogen getting condensed, and because it's getting condensed, it gets hot. It gets so hot the center starts doing "nuclear fusion". That's when you take two hydrogen’s, smash them together, and get helium. You basically put together two atoms.

When you put together two atoms, it releases a lot of energy, and that's what keeps stars burning and hot.

So now we have Hydrogen clouds, which became stars. Well these stars keep putting together atoms to get bigger ones, like oxygen, carbon, iron, and tons more. When a star dies, it explodes, and all the stuff it made, (oxygen, carbon, iron, ect.) forms new clouds. These in turn become new stars, and so on.

Planets form when all the iron and other metals clump together and form a big ball of metal. Those clumps of metal (planets) orbit the stars.

When Earth was created water (H2O) started to cover the Earth. This is because the melting rocks inside the Earth give off H2O sometimes, and all the water vapor covered the Earth, and it eventually rained all that water down.

Here are the answers to your questions:

1. The big bang was a long time ago. A lot of stuff happened since then, and the effects of the explosion don't really affect us that much.

2. If you cool down gas, it becomes a solid. Stars are hot, and that's why they are gas. If you were to cool down a star, it would be solid.

3. Evolution has absolutely nothing to do with the big bang. I can explain that too if you want. Just email me asking and I'll reply with an answer.

Hope that all helped.

Answer 2

How cute, ur just 13? anyways...

The big bang theory proposes that the universe was once said to be extremely compact like a small ball, dense, and hot. An "explosion" called the big bang, occurred a long long time ago like about 13.7 billion years ago, and the universe has since been (and is still) expanding and cooling.

According to the big bang theory, the universe expanded rapidly in its first microseconds (that's many times smaller than a second). It's the only thing that existed at the beginning of the universe, and as the universe expanded and cooled, this force separated into those we know today: like gravity, electricity, light and other stuff.....

Do not be disappointed if you don't really understand the Big Bang theory very well. I don't either. It is 'FAIRLY' simple to explain in words, but it really owes its basis of explanation to General Relativity. I never understood that, though I studied Astrophysics for years.

Probably the nastiest concept in the Big Bang to get your mind around (or at least, to the limit of my mind) is the whole idea that space and TIME are connected. We always hear reasonable questions like "What came before the Big Bang?" and "Why did it decide to JUST BLOW UP 13.7 million years ago?"

If you can grasp that the Big Bang was the expansion of Space itself... or running time backwards to the beginning, that space shrinks to a singularity, then the same must have been true of time itself. If space existed as a singularity, then so did time.

So, when someone asks, if the Univers is 13.7 billion years old, what was happening 14 billion years ago? Just ask them what the score was at Super Bowl 0?

Answer 4

One way to understand the concept of an expanding universe is to draw dots, representing galaxies, on a balloon. As the balloon is inflated, each dot moves away from all the others. To a person viewing the universe from a galaxy, all other galaxies would seem to be receding. The distant galaxies appear to be moving away faster than the near ones . Most astronomers now believe that this expansion will continue forever.

Answer 5

Hi. The Earth is COVERED by a thin layer of water. It is mostly iron. The stars fuse hydrogen into other elements and when they bow up this matter is assimilated into next generations of stars. Evolution only occurs when a life form adapts to its environment.

Answer 6

i will give you a link you can see vedios of the big bamg and other physics topics clear your doubt and enjoy.i am 12 years old. from the vedios in the website choose riidle the big bang vedio.thanks

Answer 7

I can give cogent answers to your questions, but they would be too lengthy for this forum. If you like, email your question, and any others you might have in a similar vein, to me and I will reply. It really does all make sense, and isn't that hard to grasp.

Answer 8

the world is covered with water and it dries up and gives us land. under the core is iron which cannot be melted by magma. The stars exploded up into tiny pieces and made matter.

Answer 9

First there was big bang, then there was bing bang, then came bling bang and finally we have bling bling
