can you tell me about the origin of universe (also see details)?

Question

big bang and other theories begins with some sort of things just from begining(like all objects were cluster of fireball). I want explanation just how that object too came into existence.

Answer 1

The strongest theory about the origin of the universe (and most propably the right one) would be the 'Big Bang' theory. It states how the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The Big Bang theory is based on the observed Hubble's law redshift of distant galaxies that when taken together with the cosmological principle indicate that space is expanding according to the Friedmann-Lemaître model of general relativity.

And the big bang isn't just a theory, experts are now starting to realize that this may be what really happned, they have alot of proof. For example, heres a pharagraph taken from Wikipedia, about 'redshift':

"The current models of cosmology derived from general relativity, show that space is (currently) expanding. As a result, objects within the universe are moving relative to one another, creating the cosmological redshift. For z < 0.1 the effects of spacetime expansion are minimal and dominated by the peculiar motions which cause Doppler redshift. This led to initial interpretation of the cosmological redshift by Slipher, Hubble and others as a Doppler effect, as their sources were nearby in astronomical terms. In reality, the properties of the source are not modified, but the photons will be stretched as the space through which they are traveling expands, increasing their wavelengths."

But where did the big bang come form? What caused it? Something must have caused it, and what caused this something, and the something before? I just goes on forever, thats why most people think that there was never a time when there was 'nothing'. And this is propably where the idea of 'god' been living from forever originated, because as an aitheist I belive that 'god' is acually the universe given a name by the ancient chatolics and worshiped, but lets not skip subjects.

Now there is the question of, where are we in the universe?
When the Big Bang occured, did all the matter fly off to different directions, thus forming a spherical universe?

Or was all the matter beamed to one direction, like a giant laser?

What I think is that there was always an 'empty space', an endless void. But somehow an explosion happned somewhere in it, resulting in.... the universe.

Here's a website about the big bang that might be interesting:

Hope this answers your question, its basically everything what is known of the 'origin of the universe', mixed with some of my toughts and theories. =D

Answer 2

If Einstein had told that that "cluster of fireball" was created from zatombie.......what would you do?

you will ask how zatombie came into existence :))

I can understand your dilemma but nobody knows the answer and it can never be known.

As some physicists say that some time just from vacuum a pair of 'particle' and 'anti-particle' is created.

Assuming that as a possibility......out of nothing 'universe' [matter] and 'anti-universe'[anti-matter] was created. If this is true than you won't feel the need to ask further questions.

NOTE : There are a thousand ways to go mad. "what was before bigbang" is right on the top of the list :))

Answer 3

actually i favour the BIG BANG THEORY. what happened was that a huge mass of matter called the PLANNUM ATOM existed initially. due to some disturbances that arose in it, maybe due to some external agents like energetic rays,etc., causing it to explode and burst open all its contents, which formed the UNIVERSE.
NOW starts the tricky part of your question. thus far all of us have made through our Physics books.
BUT how was this matter formed, you mean! as far as my thinking, the dust particles, gases, extranuclear matter, etc present in space at that time came together due to the GRAVITATIONAL FORCE AMONGST them and clumped together to form the huge PLANNUM ATOM(called atom because it was the building block of universe).
AGAIN where did these factors come from to make the PLANNUM? well, this may have involved nuclear and chemical changes. maybe different kinds of radiations struck each other or something , if present leading to their formation.
AND now the rays? well, maybe the ageing space led to their formation. but also vacuum, even if ageing should not change anyway! then maybe they entered from some other universe(scientists recently predicted the existence of a multiverse-having many universes), or some other process unknown to us now.
YOU just cannot say that God created the starting matter out of His Divine powers because every step of God also is scientific! even His Divine works follow science! rather He created science and works according to it. yeah, 'tis true. open any religious text and you'll realise. there is a total mention of spirituality blending with science!
HOPE YOU GOT YOUR ANSWER.

Answer 4

I think scientists have extrapolated what happened some 1* 10^-4 second after the big bang, not exactly sure about the figure, but noone knows before that.

Answer 5

There is no answer. Some things are accepted as fact. For all cases one has to assume things were just there. In this case there is no surrounding detail for hypothesis. The first fact is assumed.

Answer 6

What could have created something from nothing? Since you are a genious, if you search deep within you, you already know.

One clue is that It had to be able to use the infinite vacuum.

Answer 7

big-bang is a theory! but that does`nt mean in real! I dont think anyone chould tell you something specific. You have to be there to or ,that something happened!

Answer 8

I asked that question to my astronomy teacher in college... and he said, "How the hell should I know!!" I'm not even kidding. I have to admit, he was the most entertaining and insight professor i ever had though....

Answer 9

well i can guess some people will be saying "god created the universe" anyway it is sorta impossible to explain with science and magic and religion...well not religion because you can make up anything with religion anyway my theory is that it has something to do with parallel universes or maybe our universe is an atom in another even bigger universe or something but i dunno

Answer 10

And God said, 'Let there be a Big Bang'. (Covering both theories.)
