What was the reason or mechanism that caused the big bang?

Question

A small ball blew up and formed the universe. Why did it blow up? What cased this to happen? No religious, philosophical, or smart Aleck answers please.

Answer 1

All right. Let's keep it simple here. We could talk about string theory and m theory and anti-matter all night, but it isn't going to help you understand the big bang any better.

So just ignore all that and concentrate on the basics.

All (or much) of the matter in the universe (doesn't matter what it was) possibly a lot of Hydrogen or other subatomic material coalesced together because of the gravity of this material. We have no idea how long this took or where this material came from. Anything that happened before the big bang (singularity) is beyond our knowledge. Anyway, as this material came together over a very very long time the pressures in this ever more dense ball of matter began to rise. More matter was attracted and added to this tremendous ball of "stuff." The mass of this ball of stuff was tremendous, because it contained most of the matter in the universe. The volume of this ball probably got very large at first but eventually began to crush down under it's own gravitational weight. Now here we are, with a ball of matter containing most of the mass of the universe under tremendous pressure from its own gravity....

BAM...! The first Fusion reaction begins and races through the core of this material. The gravity, while huge, is not strong enough to maintain all of this mass and nuclear energy in one ball any longer. The material flies apart in many directions, some of it undergoing nuclear fusion, some of it just nearby and along for the ride.

The rest we can see as the current expansion of the galaxy.

I realize I have over simplified this singularity and have glazed over some of the more delicate steps, but I don't think any Baloney about anti-matter or the incredible complexity of tenth dimensional string theory is going to help people truly understand the basic reasons for the big bang.

If you have specific questions about the process, just drop me a line.

Cheers.

Answer 2

No one can really be sure! Cosmologists can only infer from observing the expansion of the universe and calculating back to a time when there was nothing but one point! It had no dimension because there was no such thing as size, volume, weight or even time because everything was in one infinitesimal point at one time. I read a definition of TIME: Time is what keeps everything from happening at once. I add: ..or continuously. And perhaps the assumptions made are wrong that running it backward would give an answer. Only recently have they discovered that it has sped up, and only theories what caused the speedup in the 'Cosmological Constant'. The Big Bang is generally accepted because of the 'echo' seen in all directions that is Doppler-shifted to a background radiation. But astronomer Fred Hoyle had a different theory nearly 50 years ago of the Steady State Universe. That may explain the speedup through spontaneous creation of material to fill the voids. And that may be what Dark Matter and Dark energy are. That may be either the cause or the result of the expansion. There may be another reason for the background radiation, the spontaneous creation of matter in the voids.. and maybe it is not possible to back it all up to a single point - It may still appear much as we see it today but not the same galaxies, stars and planets.

So, I don't know and I think my answer may apply to all the cosmologists.

Answer 3

It is expected it was a contracting singularity causing a huge gravity well and as the atoms that make up this singularity get too close to each other they start to fuse and that causes heat and gamma rays to be emitted and as more and more atom fuse a chain reaction occurs, heat is generated and the singularity starts expanding outward at great speeds and under tremendious atomic pressure.

Once fusion (the nucleus of two atoms compressing or fusing together to make a new larger atomic element) is acheived en mass and the chain reaction starts (billions and billions of atoms fuse, generating massive heat, emitting cosmic or gamma or xrays and eventually photons of light) the singularity starts to expand at a very fast rate and the results is a gush or expelling of hot mass into the universe at or near light speeds plus comsic particles that travel at light, which make up the edge of the universe.

The cosmic signature was found in the 1960s and that put an end to Fred Hoyle's Steady State movement.

Distant objects like Quasar that move at 2/3 light speed also show that most distant of objects move quite fast from the initial fusion explosion.

Mass near the center moves slower.

It is expected there still exists some dense singularity particles which have huge gravity wells.

Answer 4

the regulations of physics state that there is causality for each action or reaction. gadgets do no longer pass till yet another merchandise or tension interacts with it. Similarily, action does not quit till laid low with yet another merchandise or tension. you're assuming the the "huge Bang" became the beginning up of each little thing. have you ever seen that different activities would have preceded the "huge Bang"? consistent with risk like the cave in of a prior universe right into a microscopic quantum singularity interior a black hollow, the mass of which so great as to reason the "huge Bang" to happen? We in basic terms have not got the certainty to understand the dynamics in contact. yet prescribing expertise to the form we dont understand, or another mystical or magical impact, is a shortsighted way of drawing near the difficulty. This has been carried out in the process mankind's background...we continuously look to create a God to regulate issues we don't understand. Gods of hearth, or the sunlight, or maybe probable today's Gods...

Answer 5

I just watched a show on this recently and they were saying the big bang as we know it, was really the formation of OUR universe. the newest theories are that there are mulitple universes and dimentions or whatever. These universes are very fluid and are constantly moving about. when two crash into eachother some of their cosmics parts colide and create a new universe. I dont know exactly how all those universes came into being. Apparently there is this theory physists and astonomists call "m-theory" that answers all these crazy questions about the universe and other dimentions and stuff. google m-theory. it is very in depth and confusing but there are some good sites out there that put it in lamemans terms.

Answer 6

Two masses of subatomic particles floating around in the void one positive and the other negative (or anti matter) acidentally met. As they were opposites there was a natural attraction between them. From that meeting and joining the big bang occurred. The result of that joining was the birth of the Universe and since then nothings been the same.

Answer 7

We know that the universe is finite so it had to have a beginning.
Before the beginning there was nothing,but this nothing had to have a potential and the potential had to be finite or it could never have triggered.
The finiteness of the potential triggered a single space-time pulse of minimum size and duration.
This pulse continued and evolved into the universe we see to-day.
It couldn't be the result of a primordial egg because it would have had nowhere to wait and no way of knowing when the blow up.

Answer 8

There is no theory on this. Suddenly there was an intense amount of light. Nothing else but pure energy in the form of light. After a short time it cooled and expanded enough for the energy to convert to matter. E=mc^2

No one knows where the light came from other than God.

Answer 9

no ball. Sorry.
no particals. Sorry again.

there was nothing (sorta) but just two blobs of different dimensions floating around in the 11th dimension

they slap into each other

and cause new dimensions to burst out.... like ours.

it happens over and over and over

M theory
It can't be considered theory anymore...
If the math works, then why not?

Great video I just found. kinda long, but hang in there. They explain everything in the end.

Answer 10

The universe was very dense. Then Matter and Anti-Matter collided. Cuasing a huge explosion/energy. At least that is what i've heard/watched on tv
