If the big bang was the beginning of everything, what actually "banged"?

Answer 1

god slammed the door on jehovahs, cause they said up ur Uranus, and he looked like pluto.

Answer 2

In physical cosmology, 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.


Good Luck

Answer 3

Well, it wasn't actually a bang, more of a sudden massive expansion. The term big bang was coined by Fred Hoyle who hated the theory and was being sarcastic.

But it was something called a singularity that went boom. A singularity is unimaginably small and heavy. This will give you some idea of it's smallness:

. See this dot - you can fit 500 billion protons (subatomic particles) onto it. Take one of those protons and cut it up into a billion pieces, and what you're left with would be about the size of the singularity. It was so small it had no spatial dimensions.

That's what suddenly expanded. How or why nobody knows.

Answer 4

The big bang theory does not claim that the big bang was the beginning of everything. The theory is mum on what might have gone before. The big bang theory caused the beginning of space-time, and the universe as we know it now.

Answer 5

The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions.
In 1927, the Belgian priest Georges Lemaître was the first to propose that the universe began with the explosion of a primeval atom. His proposal came after observing the red shift in distant nebulas by astronomers to a model of the universe based on relativity. Years later, Edwin Hubble found experimental evidence to help justify Lemaître's theory. He found that distant galaxies in every direction are going away from us with speeds proportional to their distance.

The big bang was initially suggested because it explains why distant galaxies are traveling away from us at great speeds. The theory also predicts the existence of cosmic background radiation (the glow left over from the explosion itself). The Big Bang Theory received its strongest confirmation when this radiation was discovered in 1964 by Arno Penzias and Robert Wilson, who later won the Nobel Prize for this discovery.

Although the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions.

Answer 6

nothing, it's just the word to describe how everything came from a singularity (where everything is packed into a space so infantesimally small, it's 10000000000000000000000000000000000000000000000000000000000000000000000000000000 th the size od this full-stop . ) the singularity just expanded really really fast, it was like an explosion, but nothing went bang. later on there were collisions between antimatter and matter, but that was not at the beginning.

Answer 7

I understand your question. It's the first thing I think about when I hear or read about the "big bang theory". I believe some scientist think they HAVE to be able to figure everything out. Claiming that there was nothing in existence before the so called big bang is ludicrous.

Answer 8

As I understand it, all matter as we know it that makes up the entire universe was compressed into the volume the size of the head of a pin. It seems ludicrous to visuallize this, but this is what we think happens in black holes on a smaller scale. The gravitational field of such a large mass constrained in such a small volume is enormous.

Then something (God) caused the compressed matter to explode (bang) and all the universe began as expanding matter, and is still expanding to this day.

Answer 9

A long, long, long time (14.7 Billion years) ago there was this huge, monstrously massive thing that was intensely hot. It was so hot that astronomers calculate its temperature at 1,800 trillion trillion degrees F. It exploded.
It didn't have a name because there was no one alive to name it. No one could live on something that hot, or live anywhere near it.

See Ian Ridpath's Book, ASTRONOMY, DK Publishing, NY, NY. In there you will find an excellent illustration of the suggested event that happened.

Answer 10

There was an explosion, one that went from zero mph to the speed of light in one-thirty billionths of a second.
It originated as a single space-time pulse that emerged from a mere potential 10 to the minus 95 sec. after zero.
The time pulse maintained the existence and expansion of this primordial universe which matured at about 2cm in diameter.
Nothing was associated with this entity except a quantizing error that allowed it to evolve into the universe we experience to-day and of course us.

Answer 11

A singularity.
The compression of the whole of space-time to an infinate point.
Nothing came before the singulairty because there was no time for it to exist.
