How The Universe Was Structured After The Big Bang?

Question

It is reasonable to expect that matter should have been scattered everywhere at random after the explosion. But, it is not. Instead it is organized into planets, and stars, and galaxies, and clusters of galaxies, and superclusters of galaxies. If a bomb exploded in a granary, would that cause all the wheat to fall into neat sacks and bales on the backs of trucks ready to be delivered or, shower the grains every which way.

Answer 1

The Big Bang is not an explosion in the usual sense. In a typical explosion, everything moves out from some central point. In the Big Bang, space itself is expanding. Furthermore, in a granary, the gravitational effect of the grains of wheat is not a significant factor. For the gas and dust from the Big Bang, it is a crucial aspect of the dynamics. Finally, you seem to think that the galaxies and everything are much more organized than they actually are. While gravity made them come together, the internal dynamics of galaxies are quite complicated. The planets and solar systems are very small scale phenomena when compared to the overall expansion of the universe. Again, they come together because of gravity.

Answer 2

I believe you are thinking that right after the Big Bang everything was already made, like the stars, planets, galaxies, et cetera. If that is the case, you are in for a shock.

Right after the big bang, the only things that existed were energy and subatomic particles (no stars, or anything bigger that a neutron for that matter). A long time after the Big Bang, when it was cool enough for atoms to form from the particles, matter was then in the form of gas and dust randomly distributed throughout the universe. These "clouds" then started to form the galaxies. After a few billion years, within the galaxies, stars formed. At the same time some of the galaxies started to form clusters and superclusters.

Then some of the stars died, releasing "light" elements (hydrogen and helium) and "heavy" elements (all others). The light elements that were released formed new stars, and the heavy elements formed a nebula, or dust cloud. Some of the nebulae surrounded stars. These, over billions of years, started to form a planetary system. That is why the universe seems so orderly now despite a relatively violent start.

Answer 3

the big bang occurred and the gasses and debris was held in orbit by the sun
as time passed the gasses and particles collided with one another and hence grew in mass first creating Jupiter, Saturn, Uranus then Neptune (the Gas Giants) these are in the correct order. the planets switched because of their gravitational drift due to the mass of matter being dragged from the Khyber belt
the other planets where formed by these planets gravitational pull extracting matter from the Khyber belt into the center next to the sun and back out hence causing gravitational drift I'm not sure but magnetics may have also played a role in this
after a few years the solar system as we know it was formed due to the gravity of all the original planets pulling matter in and then giving it the opportunity to gather mass

I learnt this off of either the Sky at night (BBC Production) or an open university program on at a some un-godly time in the AM.

Answer 4

well, the big bang was nothing but energy, when that energy was released, it was so much so fast that some of it was converted to mass, that mass in the form of particle's, each particle with a small amount of gravity. Started to attract other particles. Over the billions of years, and many changes along the way. They have combined and continue to change and make other attraction. Meteorites are an example of the on going attraction. Comets are another, the moon is held in place by the gravitational attraction's.

Answer 5

I prefer to think of the laws of nature more as habits which have built up over time rather than absolutes, so I see patterns of developement. It is thought that once an action is accomplished that a physical template has been formed making it easier for that action to be repeated. This is called formative causation. Yet formative causation transcends time and space so it can perhaps more accurately be described as morphic resonance.

Randomness is an entirely different matter because mathematically it cannot be proved or disproved. The solution to this according to proponents of of quantum mechanics is to take positive pi in comparison with negative pi so that it aggrees with Plank's constant and Einstein's theory of relativity sufficiently enough to explain randomness in subatomic particles.

Answer 6

Sound waves that roared through space after the big bang left behind a subtle imprint in the way galaxies are clustered today, reveal two major studies. The results bolster the standard theory that the universe is flat, and measuring the distance between the sound ripples may provide a new cosmic yardstick to probe the past.

Two independent teams mapping the universe have found that galaxies are currently slightly more likely to be 500 million light years apart than any other distance. The finding, a result of the conditions in the early universe, was announced on Tuesday at a meeting of the American Astronomical Society in San Diego, California, US.

The results back the standard s of a flat universe, ted by dark matter and dark energy, that has been expanding since the rapid period of inflation just after the big bang. Generally speaking, the distance between galaxies matches the pattern of sound wave ripples from the early universe.

"The triumph is that the signal is seen at the expected location," says Richard Ellis, an astronomer at the California Institute of Technology, US, and a member of the 2-degree Field Galaxy Redshift Survey (2dF) team.

The discovery is especially powerful because the groups used different observations and statistical techniques to arrive at the same conclusion, says Martin Rees, an astronomer at Cambridge University, UK.

Matching predictions
Astronomers from 2dF studied the locations of 221,000 galaxies using a telescope in Australia. Meanwhile, the Sloan Digital Sky Survey (SDSS) mapped 46,000 bright, red galaxies within six billion light years across an area of sky about 10 times as large with a telescope in New Mexico, US.

The finding agrees well with predictions made 30 years ago about how the nearly featureless infant universe should have matured into the structured place seen today, says Rees. He adds that it dovetails with observations of the big bang's afterglow - called the cosmic microwave background radiation - which supports a universe composed of just 4% normal matter, 25% dark matter, and the rest dark energy.

"The concordant picture we have of the universe is hanging together amazingly well," he says. "In a way, it would be more exciting if we found a glaring inconsistency."

The groups trace the 500 million light-year pattern to the first instants after the universe burst into being 13.7 billion years ago, when mysterious quantum fluctuations bubbled through space. These created pockets of different density in a searing fog of ionised gas and photons that eventually clumped into structures like stars and galaxies.

But early on, when clumps of gas began to collapse and grow, photons trapped in the dense fog exerted an outward pressure that counteracted the growth. These opposing forces set off pressure, or sound, waves that oscillated within the fog.

Freeing photons
But beginning about 400,000 years after the big bang, the universe had expanded and cooled enough for electrons and protons in the fog to start combining into neutral hydrogen. That freed both the photons - which became the ancient "afterglow" of light seen by astronomers - and the trapped sound waves to travel unimpeded through space.

"Instead of ringing, the waves kept going," says Daniel Eisenstein, an SDSS team member at the University of Arizona, US. He says it took about 600,000 years for most of the trapped photons to be freed, so the sound waves from these "overdense" regions would have travelled about 500,000 light years when the ringing stopped.

"That expanding sound wave originates from all points in the universe, like you've taken a handful of gravel and thrown it in a pond," says Eisenstein. The outward ripple from each sound wave grew to be 500 million light years in length because of the expansion of the universe, he says. The birth of galaxies tended to occur at the leading edge of the ripple, where matter was slightly denser and gravitational forces slightly stronger.

But the effect is subtle - galaxies are just 1% more likely to lie 500 million light years away from each other than at other distances, says Eisenstein.

Still, statistical analyses can pick out the effect. Future studies could look for this clustering to probe how the structure of the universe evolved over time. The yardstick could also test the accuracy of "redshift" measurements - upon which astronomical distance estimates are built, says Rees. I found this on the internet i think thats wut ur talking about

Answer 7

It was a very very very big big big bang like a trigatron blast. Earth is one of the p[ieces from that explpsion ans so are other plantes that float out there and the stars. There is no telling what is on the other side, but I rather not find out. I would guess they have discovered the truth to relativitiy and visited earth and said lets get out of here guys their still morons.

Answer 8

AS observed in the CMB, the big band singularity was not uniform. It expanded and sent material everywhere in an uneven way. Thats why the universe is not a simple pool of plasma.

Answer 9

A key point to note here would be that a uniform distribution of matter would not be "random". Big clumps of matter scattered about, however, would be.

Answer 10

that's a good question. i figure that some clumps of matter must've been larger and their gravity may have pulled in other matter and began to form planets ect.
