Could anyone explain the Big Bang theory to me...further?

Question

Could anyone explain the Big Bang theory to me...further?

Answer 1

Actually there was a small particle tat came outta nowhere..

It exploded to give a group of particles..

then each of the particle exploded to give Lots of particles..

,

tis continued till when there were so many particles tat it exploded with a BIG BANG!!!!! (hence the name)

after that all the particles joined to form planets, stars, sun & all the things of the Galaxy..

(donno HoW tat HappeNed but (-.- ). z Z ....  )

Answer 2

It's going to be way hard to explain, there are so many different versions/theories about it.  It's hard to pick which one to describe, harder to summarize all the different ideas.

I'm assuming you realize that the Big Bang Theory is the most widely accepted theory of the Universe's creation.  Way back around 13.7 billion years ago, a hot, dense mess of matter like quarks and such existed.  Something was triggered and suddenly the dense thing started to expand.  

The Big Bang is an inaccurate title; there actually was no explosion, just a huge expansion.  Imagine stretching a rubber band, it expands but new matter isn't created.

When the Universe first started to expand, matter was a mess.  There were your particles of matter flying everywhere.  But as the expansion got larger, the heat started to spread out more and the Universe is gradually getting cooler.  Matter clumps, creates First Generation Starts (Which are HUUUUGE super stars, so big that they created super heavy elements such as gold, platinum, and such.  Today, stellar nucleosynthasis ends at iron and nickle, much smaller!)  

Anyway, those First Gen Stars died in the best way possible, with a huge explosion, and heavy elements started to mix with lighter ones.  Light elements such as hydrogen and helium accreted and clumped until they got super hot, and attracted more matter.  This lead to galaxies, more stars, and solar systems.  There's SO much more information, I suggest you read more about it!

So anyway, the Universe is expanding, and that's the main gist of it.

Answer 3

Further than what?  The big bang is a theory to explain what we see.

We can see that galaxies are all rapidly moving away from each other, meaning everything was closer together in the past.  Redshift shows us that things that are farther away from us are moving away faster than nearer objects.  Extrapolate far enough and you'd have a whole bunch of matter concentrated in a very small space about 15 billion years ago.

Imagine three dots on a balloon, two close together on one side and one on the other. Now blow up the balloon.  The dots all move away from each other, but the dot on the far side moves away faster.  

This is the most simple explanation I can come up with...

Answer 5

Step 1: everything that would eventually become the universe we see today is expanding from a tiny spot.

I know you think I skipped a step, you're wondering 'Where did it come from?' or 'What made it start expanding?'  But those questions have nothing to do with the big bang theory.  The big bang theory begins AFTER we already have an expanding universe.  The big bang theory is NOT about where the universe came from or what started the universe, it is only about the structure of the universe.

Step 2: as the universe cooled, the forces of nature we know (electromagnetism, strong and weak nuclear) came into existence.

Step 3: The universe cooled more, and particles and antiparticles could form.  There was almost an equal number of particles and antiparticles, which kept smashing into each other and exploding.  For some reason we ended up with a lot of leftover particles and not many leftover antiparticles, so almost everything you see today is made of regular particles.

The first three steps happened in less than a second.

Step 4: a few minutes have passed and the universe is cool enough to form hydrogen and helium nuclei, but it will take another 400,000 years to cool enough to form actual atoms.

Step 5: a long time passes, during which the gravity of the atoms draws them together into gas clouds, which condense and form stars, which collect and form galaxies, which collect and form clusters.  Some of the stars explode to make new gas clouds, fusing heavier atoms in the process.  These new gas clouds collect and make new stars, and since they now contain heavier elements, actual solid planets can now form when the new stars form.  Earth is one of those solid planets around a second generation star.

Answer 6

From a point very small, God caused caused every thing to come from with a great deal of energy.
