What came before the Big Bang, assuming there actually was a Big Bang?

Question

If as some scientists suppose, everything in the universe at large began with a Big Bang, and a point singularity, then my questions are simply, . . What came before the Big Bang? If the laws of physics are null and void at a point singularity, then how could such a singularity explode in the first place? How is this considered science if there is NO laws of science that can determine what took place at this hypothetical singularity during the Big Bang, let alone before it supposidly came into existence?!!!!!

Answer 1

The big crunch maybe... the collapse of the previous universe in an everlasting Big Bounce.

or

it was just a vast emptiness, the effect of eternal expansion of a previous universe, then a quantum fluctuation came along and blew a gaping hole out of nowhere filled with our universe

or maybe one of billions of other theorys.. theres more of them then there is stars IN the universe

Answer 2

It seems fairly likely that there was a Big Bang. The obvious question that could be asked to challenge or define the boundaries between physics and metaphysics is: what came before the Big Bang?

   Physicists define the boundaries of physics by trying to describe them theoretically and then testing that description against observation. Our observed expanding Universe is very well described by flat space, with critical density supplied mainly by dark matter and a cosmological constant, that should expand forever.

   If we follow this model backwards in time to when the Universe was very hot and dense, and dominated by radiation, then we have to understand the particle physics that happens at such high densities of energy. The experimental understanding of particle physics starts to p**p out after the energy scale of electroweak unification, and theoretical physicists have to reach for models of particle physics beyond the Standard Model, to Grand Unified Theories, supersymmetry, string theory and quantum cosmology.

   This exploration is guided by three outstanding problems with the Big Bang cosmological model:

1. The flatness problem

2. The horizon problem

3. The magnetic monopole problem

Answer 3

The big bang does not deal with the 'singularity', only the Planck time (a fraction of a second) and after.

You've fallen into the common misconception of thinking that the big bang is about the origin of the universe.  It's not, it's about the structure of the universe.  So we will not be talking about the big bang here.

When talking about the singularity, it's not that the singularity is outside science, it's that our current science is not capable of describing it, which is why there are no scientific theories about it.  The singularity doesn't break the laws of physics, our 'laws of physics' are in some way incorrect or incomplete.

And most physicists agree that time is a dimension of our universe that came into existence at the same time the spatial dimensions did.  So asking about 'before the big bang' is basically a nonsense question, there's no such thing as 'before the big bang', time did not exist then.  It's like asking 'what's north of the north pole.'

Also, while it's common for people to say and think of it as an explosion, it wasn't.  An explosion implies that it existed at a point within space, and exploded out into space.  What happened was that space did not exist at all, and it was an expansion of space itself.

Answer 4

The universe expands and contracts much like everything else in life, its been expanding for the last several billion years but one day will do the opposite and contract into a mass so dense that it will explode all over again. Its part of the circle of life....

Answer 5

First, the Big Bang is misleading...it was not an explosion per say, but a sudden, rapid release of energy and expansion.

All the matter and energy we know of in the Universe was condensed into the point singularity of energy.  That is what existed before the Universe as we know it.  Nothing but a point of energy.

Since the singularity was pure energy and according to the known laws of conservation of energy...energy cannot be created nor destroyed, it can only be transferred to do work or transformed into another form of energy or matter.  The singularity of energy has always existed, exists now as the total matter and energy in the universe, and will always be the total matter and energy in the universe.

THE HOW:  According to new theories (String Theory and M Theory) relating to this, the "Big Bang" was caused by a transfer of energy from a higher dimension to our lower dimension.  We exist in the fourth dimension...three coordinate system as 3D and time is the fourth dimension.  String Theory mathematically explains up to 10 dimensions while M theory mathematically explains 11 dimensions, the eleventh making alternate universes possible.  

While the laws of physics we currently know behave differently at a singularity...they are not null and void.  The lack of an explanation at this time does not mean it is all false.  It just means we have more research to do and discoveries to make in order to form an better explanation.  

Answer 6

i dont know...

probably the singularity and god... or gods depending on ur belives

Answer 7

There was no before. It is a very strange concept about a very strange time. The "big bang" was invented by Fred Hoyle to make fun of the concept. Then evidence began to pile up that the universe has expanded from a single point. There was no distance, no time before, no light, not even quarks existed I think.

What we have is a universe whcih seems to have derived from a big bang. Fred Hoyles steady state has no evidence for it.

Answer 8

Time started with the Big Bang.. So asking what came "before" the Big Bang is nonsense.

This is a question no scientist will ever be able to answer.
