Big Bang Theory???

Question

What is the proofs that it is true and meaning of BIG BANG THEORY?

Answer 1

No no no... ignore all these people calling big bang theory just a philosophical idea with no proof... if there were no evidence supporting the theory, then scientists wouldn't be studying it... the best evidence we have of the theory is the cosmic microwave background radiation, discovered exactly the way scientists predicted in early 90's (or confirmed, rather). it is basically the left over radiation from the bang itself. other evidences include abundance of primordial elements and galaxy evolution and distribution. currently, there are very few scientists who doubt that big bang occurred.

Answer 2

I do not support the theory. As you say the branches of Physics, Mathematics, and topological astronomy as well as other sciences are just to much to put it all together. Remember the big bang is just a Theory and not a fact! It cannot be proven as a fact! Even Hawkings can't get back to point zero, and he never will. The reason is he is looking for the beginning. So, let us now put the big bang on the shelve for a minuet and let us look at the expanse of the universe as always being there. Not everything that is in it. but an expanse that has always been. Now we have a starting point! an empty eternal expanse that has always been there. Everything in the expanse we see today has order This we call the universe.It continues to expand in the eternal expanse. everything follows all the rules of physics, and math. So just how did the three dimensional universe as we know it start? We know from Einstein's formula E=MC^2 that we can get energy from matter. We also know from Newton's law of physics that every action has an equal reaction. So, taking dynamic energy one could create everything and start the motion of everything created in the expanse with order. Is this logical? Yes! Is it true? It has to be because we continue to discover more about it using the laws of physics and mathematics. So this would open the biggest question of all, just who or what created it? This my friend I will leave up to you to decide.

Answer 3

The Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The theory is based on the observations indicating the expansion of space in accord with the Robertson-Walker model of general relativity, as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.

Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity.

The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the universe (Hubble's law) began — calculated to be 13.7 billion (1.37 × 1010) years ago (±2%) — and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory.[1]

Answer 4

This isn't particularly "solid" science. That is,
people have proposed a theory and most of
the credible repeatable evidence supports
it and nobody has found anything that
directly contradicts it that adheres to
scientific vigor.

However, it may pose more questions then
it answers.

Most of the "evidence" is actually extrapolation.
That is, by studying the current motion of
the stars, galaxies, etc, we can begin to
understand where things started, what
the energy/mass configurations were, etc.
We can look at average temperature in
space (2-3"K) and extrapolate backwards
to determine the energy, etc.

However, it depends on extrapolation
which is fickle. If 1 woman can produce
1 baby in 9 months, than surely 9 women
can produce 1 baby in 1 month...

Still, as of 2007, this theory seems to be
the best we have - that is, it allows
us to ask questions, use the theory to
predict answers, in some cases we can
actually check our predictions. By-and-large,
the more we can see (optically, using
other forms of teloscopy, etc), the surer
we are.

Answer 5

The oldest question is how did it all start. The answer has been pondered by the most brilliant minds in History and the most common is the big bang. If you look into the construction of a star, how gravity affects matter and how Neutron stars can support infinate density, what happens when infinate density collapses. That is the big bang.

Answer 6

I have to say that i vote with john y, the big bang theory is some the scientist probly mistaked for a hhhhhhhuuuuuuuuugggggggggeeeeeeeee supernova that happend a few thousand years ago, it probly was a giant star that supernova and made a huge super black hole. another words the scientists actually don,t even know if the theory is even true it is something that one said to get the fame.

Answer 7

dont worry man its just an assumed theory it has really no proof.
it is assumed becoz it was found the the universe is still growing in size so it could have started growing from a small point.
the process of a point like thing breaking up into a universe is called the big bang

Answer 8

I detailed part of this in your question on Steady State.

The Catholic Priest/Physicists started with the concept of the Primordal Atom or what some call a singularity. The problem is you sort of have to take that one on faith, which again makes it religious or you have to subscribe to the Big Crunch.

No one really knows was a signularity or primordial atom is. It is postulated that ALL the mass of the universe contracts into this form.

You have to think of an A-Bomb. It starts off as a few pounds of ultra heavy mass (U-235 or P-239) that is IMPLODED by outside explosions to become even heavier for a brief moment, plus there are nuetrons introduced to TRIGGER a chain reaction.

Now, the Big Bang is NOT considered to be fission but FUSION.

The only way WE manufacture Fusion is with the H-Bomb, which requires an A-Bomb (fission) which then creates plasma and x-rays that fuse other heavy materials (P-239 and U-238) to generate FUSION.

This is not how fusion might occur naturally as in Stars. It's simply how man creates fusion.

Anyway, MASS for some reason (possibly a black hole or gravity well naturally found or just an accumulation of heavy mass becoming a gravity well) starts attracting other mass and becomes ultra heavy and falls in on itself closing up the space between charged particles (there is potentially a gap between electrons and protons and this gap is narrowed during contraction).

This mass becomes so strong that it has a gravity equal to the speed of light, thus light will not escape from the mass or singularity (hence the name black hole).

At the same time this mass might be contracting (falling in on itself or NATURALLY imploding).

This MASS or primordial atom comprises the ENTIRE universe, everything we see in the skies at night. ALL that mass is compacted into a SINGLE atom or object or singularity that is very small in size. How small no one knows for sure. Maybe it's the size of our sun, maybe it's the size of a molicule.

This, basically, becomes that mytholgoical "rock" so heavy God can't lift it.

It sucks in everything and becomes the entire universe and somewhere along the line goes critical an generates a FUSION reaction that startings things expanding OUTWARDS and the FIRST things that fly out are Gamma Radiation and then other small particles including X-rays and possibly photons of light and eventually bigger things like electrons and protons.

We're talking a FUSION expansion that happens in a microsecond and that small primordial atom stars EXPANDING like a big ball and gets very hot from the fusion and starts movwing outwards and hot electrons and protons are emitted (a form of plasma) and they start to bond into hydrogen and evnetually helium and other light elements and the plasma ejection becomes the stars and galaxies which follow BEHIND the gamma rays and X-rays at a slower speed.

Thus the EVENT horizon of the UNIVERSE is moving outward now at the speed of light with the primoridal atom is expanding at a potentially (we don't know for sure) slower rate.

We can observe things in deep space like Quasars that move at 75% the speed of light. We observe stars and galaxies moving at even slower rates.

The gamma radiation, however, is suspected at being over 14 billion light years away and moving out even further.

Thus the UNIVERSE is expanding at the speed of light each and every second to this HUGE, largely spherical entity that started out as a very, very, very small universe of the Primordial Atom or singuarlity.

The big Cruch theory is about how that Primordial Atom may have formed by MASS falling back to the center or traveling back to the point of origin and forming a huge singularity that implodes on itself into the primordial atom.

And scientists think Religious people are nuts and talk about weird stuff.

While this is not IMPOSSIBLE, you have to really take a leap of faith (that religious thing again) to accept this fact that the universe goes from something so small you can't see it with a microscope (although it could be much larger, like the sun or even a galaxy in actual size) to this universe that is hundreds of billions or even trillions of light years across as a result of the initial fusion reaction.

Carl Sagan, the late Cornell Cosmologist, said all of this, to date, comprises a cosmic month and we, humans, came about in the first hour of the last day of that cosmic month and we are still in the first few minutes of that hour.

The Bible says 6 days.

Scientists say ALL of the hydrogen in the universe (the Sun contains a lot of hydrogen) was created in the first few MINUTES of the BIG BANG and certainly by the end of the first LITERAL 24 hour day after the BANG happened.

Science says all this happened without any intellegent help. It's jsut a collection of cosmic stuff (and NO ONE can expalin where all the STUFF came from) that contracts and expands due to gravity and fusion reactions.

Religion says, God shouted NOW to set of that Primordial Atom, just like Oppenheimer did with his test in Nevada of the first A-bomb.

Other than THAT and coming from APES, Science and Religion basically agree on the similar processes associated with the creating of the universe. Genesis perfectly describes the same events after the Bang that science says happens, until we get to the making of man. Then they differ again.

Answer 9

according to big bang theory scientists beleive that 15 million years ago the universe was concentated in a small lump of atom called premeivel atom .and after some reactions which would have taken place in it then brusted {after few million years ago} and then it is beleived that since from then the universe has been expanding.

Answer 10

Th Big Bang is really a philosphical idea.
It is not a scientific theory since it cannot be tested, observed, repreated. It is not subject to the scientific method.

It is promoted strongly on religious grounds by atheists, since the alternative of Creation is unacceptable to them.

The Big Bang hypothesis has many many scientific flaws. That is it does not explain the observed evidence.
