How did it all begin?

Question

How did the galaxy's begin? I like the big bang theory but what made the atom's that collided & exploded? How did they get there?

Answer 1

Yeah. Exactly.

Answer 2

Hi:

there was a Big Bang and a great deal of light than 1 second after that, darkness return to universe and hydrogen gas cloud abounded but due the shock waves that rebound throughout the universe. Some of the cloud were push together a thus the first stars were formed and the universe lit up again and the stellar nursery were born. However some star grew too big and burnt up there fuel. They exploded with the biggest bang; short of the one big bang that made the universe and turn into very huge black hole. The gases that did not get drawn into the black hole started to orbit it and some of it got compressed and start forming stars again and even made a stellar nursery again but not as big as before and thus were the Galaxies formed. and the stars in them were burning. Over the course of time ( million of years) some of them going supernova enriching the galaxies with heavier elements like carbon, sulfur, oxygen,iron,copper,zinc, and nickel...etc and form the leftover material . There was a gigantic cloud or ice, gas ,and rock in one of the galaxy whetever by divine intellenge or not one of the star went supernova and threw a mountain size rock into this cloud of gas, rock and ice and the gravitational attraction start pulling this material toward it. and the collisions start to make the material stick and the gravity got stronger and pulled even more material toward it until it started a runaway effect. Has the material collided with the object it ; got hotter and hotter and the gas heated up until 150 million dregree was generated

And a star was born. During this time the material that didn't get drawn into the star, start orbiting it and it attacted all the other leftover materials Oh the noise of those thing hitting one another was loud and in the process generated a lot heat melting the rock and the metal seperated along with the gases However as soon as the star light was enough the heat the gases away from itself to blow away the ice and gases. but the collision still continued until 9 planets and a star to be could the Sun was born and thus that is how the Galaxies and our solar system came to be base on scienitific evidence that scienitist know today .

Rant mode on...
Why is the first reply to any astrophysics question something to do with god? Are there loads of christians out there just waiting for a question so they can reply with 'god did it'?
Rant mode off.

You have the wrong idea about the big bang. It was not an explosion, it was an expansion of space from a tiny hot dense start to a gradually less dense, cooler and larger volume.

Not a trivial question, there are several sub questions in here.
1) Where did atoms come from.
The early universe was incredibly hot or to put it another way there was loads of energy about. The most famous equation in physics is E=mc^2 but this also goes backwards, you can create mass (elementary particles) from energy, this is done all the time in particle accelerators. The early universe was full of all kinds of matter and as things cooled the protons, neutrons and electrons stuck together to form atoms. I have skipped over a huge antimatter problem here but that is for another question!

2) How did galaxies form?
Another tough one that people are still working on. The distribution of matter in the early universe was not totally uniform. The denser regions had more gravity so attracted nearby matter and so got even denser. After a few billion years most of the matter (baryonic matter anyway) was in clumps which formed galaxies. There are loads of physicists who spend their entire careers working on the fine details of this.

Answer 4

In physical cosmology, the Big Bang is the scientific theory of the origin of the universe as an explosion of space and matter, starting from an enormously dense and hot state at some finite time in the past. The central idea is that the observed redshift of the galaxies (Hubble's law) shows that the galaxies are receding from each other, which implies that they were much closer together in the past. Extrapolated to the extreme, this line of reasoning leads to the conclusion that all the constituents of the universe began at very high density and temperature (perhaps even a gravitational singularity). Since then, space itself has expanded with the passage of time, carrying the galaxies with it.

Does that answer help? I've asked that question all my life and this answer is the closest I've ever got to answering your/my question.

Another theory of mine is God created the atom which ignited the Big Bang which led to where we are today. Yep, all in seven days. God's omnipotent so I bet he can create anything in a second.

Answer 5

Well, still there isn't a right theory for that . The Big Bang theory begins with the density in that particle that explode. Were did this came form! Still we don't know!

Answer 6

We only know what happened from about a few nanoseconds of the big bang. It started form an infinetly dense singularity. basically protons and neutrons were formed from an antimatter and matter imbalance-they annihalate each other with the remains forming quaks which are the make up of protons/neutrons. the expansion of the universe caused particles to cool allowing them to combine to form heavier elements such as helium. clumps of matter then began to collect together in different places due to different strengths of gravity. these clumps of matter have become the galaxies. a massive particle accelarator is currently being built to try to find out what really happened at the start of the big bang but i would rather believe that god started the singularity. hope this helps.

Answer 7

i agree with the big bang thing altho the way it started thats a diff matter...imagine nothin, its not black so skip that thought your on, its not colorless either so dump that one too, its just nothin, but i like the idea of it collapsin in on itself again actually pretty probable when you think about it...think os something exploding like slow mo in a movie, you see evrything moving outwards from the source in waves but then the waves move back in again straight after they stop moving at a certain point....thats what could be happening with the universe...big bang explosion, the universe is constantly expanding and will soon implode or collapse on itself because there is a void at the origin, everything sucked back into the source of well everything and the process is repeated...but heres one i made earlier!!! sorry it was alll starting to sound like christmas time on blue peter at the end there...terrible shame, thought it was a good explaination!!!

Answer 8

According To M theory, 2 parallel universes collided in the 11th dimension, and the energy released created all space and matter in it

Answer 9

well, some scientists say that the universe is constantly expanding and expanding, but what if it comes to a point where the universe can't go any further, other scientists believe that the universe will eventually collapse on itself returning to the source of where it all began, and hence the BIG BANG will happen again, that's what i've heard in my short but fruitful life, just a couple of thoughts for ya,

Answer 10

big bang theory? you must believe in evolution, then? well, just so you know, there was no big bang theory. God put them there and God created everything on the face of this earth. He even made you!

Answer 11

Because of more energy and more heat being enclosed it exploded thus forming stars, planets and the universe and so many other things began to form like meterorites, etc...
