what evidence is there to support the Big Bang?

Answer 1

the complete concept of big bang is explained here... beginning to the end.

What happened before the big bang, evidence of the big bang theory, what caused the big bang, big bang theory of evolution are some of the questions asked on the Internet today.

What do we mean when we talk of big bang theory? It is in the last 30 years or so that scientists across the world accepted and confirmed the existence of the big bang theory. It has more or less been proved that the evolution of the Cosmos occurred with a big bang. There is no further denial on this fact of big bang theory.

This evidence put forward by the scientific community is further corroborated firmly by spirituality. How?


Let us travel to the beginning of time when the Cosmos is in the process of complete dissolution. What happens after the complete dissolution of the Cosmos? In the field of the spirituality... everything contained in the Cosmos is but an illusion... an act of Maya (Veil of ignorance). There is nothing in the Cosmos which is solid in nature.

Broken down to the basic building block of the universe... everything in the whole of Cosmos is a cluster of atoms and molecules. Then what constitutes the Cosmos itself? Spirituality spells out the truth... everything contained in the whole of Cosmos is but souls atmans and ether, the inert matter.

Ether is that dark black substance which fills up the void existing all over the Cosmos. Apart from ether spirituality defines the Cosmos consisting of souls atmans and nothing more. Whatever is visible to the physical senses of a human being nay every living being is limited to the use of the physical senses. Beyond the senses.... nothing exists in the whole of Cosmos except the world of souls atmans and ether.


The dissolution of the Cosmos is best defined in Bhagavad Gita, the sacred doctrine put forward by Lord Krishna in the battlefield of Kurushetra. As per Bhagavad Gita Almighty God is defined as, "the sum total of all the purified souls atmans in the Cosmos at a given point of time"! At the time of the dissolution of the Cosmos all the souls atmans in the Cosmos having purified themselves collect together to form what we know as God Almighty.

This collective power of all the souls atmans in the Cosmos... the size of half a thumb as detailed in Bhagavad Gita and unable to contain itself for long explodes with a big bang. And this big bang leads to formation of a new Cosmos... a new series of universes, galaxies, cluster of stars and solar systems.

Every new Cosmos can begin only after a big bang. No Cosmos can form without the big bang having occurred! The occurrence of the big bang announces the formation of a new Cosmos. It is the big bang theory which paves way for all the souls atmans in the Cosmos to start their cosmic travel of 8.4 million manifestations.


The big bang having occurred... it takes millions and billions of years before the system becoming conducive for life to germinate. As the conditions became conducive for life to germinate on Mother Earth... the souls atmans (within the gravitational pull of the solar system) settled on Mother Earth. This gave birth to life on Mother Earth.

Starting the journey as an amoeba and finally culminating into the form of a human being... it is only as a human being that one reaches the end of life... gains enlightenment and finally salvation!

The big bang theory announces the start of a new Cosmos... the beginning of life for every soul atman on its cosmic journey!


Spirituality or otherwise... the start of the Cosmos could not have occurred without a big bang. It is only the big bang theory which governs the start of cosmic system. There is no other means which could have led to start of a new Cosmos without a big bang.

The big bang is that phenomenon in the life of a Cosmos without which the existence of God Almighty himself would get negated. God Almighty being the sum total of all purified souls atmans in the Cosmos at a given point of time... it is needless to say again that this massive source of energy we know as Almighty God explodes with a big bang at the start of a Cosmos.

Answer 2

The Big Bang theory does have a good amount of evidence behind it. So we’ll take a look at the three biggies.

a) Cosmological Redshift: We can use spectroscopy to determine the rate at which galaxies are moving away from us. Additionally, since it takes light time to travel, the further away we look, the further back in time we are looking.

What we find, is that all galaxies in the universe are moving away from us. The further they are, the faster they’re moving away. So if we play the whole thing in reverse, all the galaxies will come back together at a single point in time. This point in time is what we call the Big Bang.

b) The Cosmic Microwave Background (CMB): Figuring that if you played everything back in time like this that all that energy would be crammed into a smaller space, that means the temperature would go up. And also since galaxies couldn’t have formed yet, we’d expect a gaseous sort of universe early on. As I discussed earlier, hot dense gasses emit photons at a peak wavelength corresponding to their temperature. Unfortunately, since things were so dense, photons couldn’t get very far.

However, with the available information, astronomers were able to determine at what density and time, photons would finally be able to get far enough that we could observe them. This is called the “surface of last scattering” and has a very specific temperature. So we should be able to look for photons with energy (wavelength) corresponding to that temperature.

But due to redshift, they will appear at a different wavelength. This radiation should appear from every direction. This was a prediction made by the Big Bang theory that was later confirmed by Penzias and Wilson who stumbled on it accidentally!

No other theory of the universe has ever been able to make such a profound prediction to the degree of accuracy the Big Bang did in this instance. Making such amazing predictions is one of the highlights of a good theory. None before or since have ever been able to pull off such a feat.

But the successes of the CMB prediction don’t stop there. Another important piece of the puzzle lies in that the CMB couldn’t be completely even. If it were, then galaxies couldn’t form since there would be no “seeds” with higher mass and thus a stronger gravitational pull to form around.

Thus, the Big Bang theory had to predict that the CMB would not be completely homogeneous. It should have some variations to it, and those variations would have to be of a specific size in order to get the universe we see today.

Early results for the Big Bang didn’t look too good for this prediction and threatened to sink the whole ship. However, the devices used were not actually sensitive enough to pick up these minute variations. But recently, with the Wilkinson Microwave Anisotropy Probe (WMAP), these perturbations have been discovered precisely as predicted.

Score two strong predictions for the Big Bang. Zero for any others.

c) Distribution of Elements: With the conceptual framework intact thanks to the first point, it was also possible to calculate how much of each element should be formed in the initial event. It should be obvious that, given a bunch of protons, electrons, and neutrons, hydrogen should be the easiest to form. Indeed, stick a proton and an electron in a room together and they’ll automatically hook up due to their magnetic attractions.

Additionally, with such high energies, it would be possible to fuse some of this hydrogen into helium and even a little bit of heavier elements. Since astronomers had a good handle on the energies, it was possible to calculate how much of each there should be. If that number didn’t match up with observations, the Big Bang theory would be shot.

Fortunately, the predictions do match up pretty closely. I stated a value earlier of 80% hydrogen, 20% helium, and neglected the rest since it would be statistically insignificant. In the universe today, we observe 75% hydrogen, 24% helium, and 1% everything else. This discrepancy is easily accounted for by nearly 14 billion years of stars cooking hydrogen into helium and other heavier elements.

So there’s three major pieces of evidence for the Big Bang, any one of which, if it had turned out any other way, would completely discredit the theory. Fortunately for the Big Bang, it has passed all of those tests, and not a single other theory has yet been able to adequately explain such things, or many anywhere near as profound of predictions (or any successful predictions for that matter). This is why the Big Bang stands alone as the premiere theory in cosmology today.

Just to add something which most people who are unducated do not know

In science a theory is a conceptual framework that explains existing observations and predicts new ones. For instance, suppose you see the Sun rise. This is an existing observation which is explained by the theory of gravity proposed by Newton. This theory, in addition to explaining why we see the Sun move across the sky, also explains many other phenomena such as the path followed by the Sun as it moves (as seen from Earth) across the sky, the phases of the Moon, the phases of Venus, the tides, just to mention a few. You can today make a calculation and predict the position of the Sun, the phases of the Moon and Venus, the hour of maximal tide, all 200 years from now. The same theory is used to guide spacecraft all over the Solar System.

A hypothesis is a working assumption. Typically, a scientist devises a hypothesis and then sees if it ``holds water'' by testing it against available data (obtained from previous experiments and observations). If the hypothesis does hold water, the scientist declares it to be a theory.

THE BIG BANG FRAMEWORK IS A THEORY WHICH MEANS THAT IT IS SUPPORTED BY OBSERVATIONAL EVIDENCE AND IT HAS PREDICTED OTHER OBSERVATIONS BEFORE THEY WERE DONE!

Answer 3

The miraculous expansion of the Universe is an evidense to the Big Bang. Some thing like that must have happened. If not such expansion would never be possible. Science has observed the nature of the universe. No other theories have properly explained the expansion of the Universe.

Answer 4

The red shift in the spectrum of light from distant galaxies is the #1 evidence. The only known cause of this red shift is motion away from the observer. Since all parts of the distant universe are moving away, it is reasonable to think that in the distant past they were much closer than they are now. Mathematically, you can trace them all back to a single point. We call that point the big bang. The validity of extrapolating the current motion back that far could be questioned though.

Answer 5

The recession of the galaxies. Astronomers are well aware that distant galaxies are all moving away from one another at relativistic speeds. Now put two and two together.

Answer 6

Some I remember are:
The fact that the universe is expanding,
The cosmic red shift;
The backgroun radiation from the explosion;
and...

you and your girlfriend get into an argument - BIG BANG! she breaks up with you!

Big Bang has some use after all ---

Answer 9

matter! I think it was more of a crash 2 dimensions smacked each other and like 2 cars all the pieces that flew off was matter.

Answer 10

when the big bang happened, i heard it
