If our universe was created with a big bang, what exploded?

Answer 1

It's a hard thing to envisage - but everything within our universe was, about 13 and a half billion years ago, compacted down into an infinitely small, infinitely dense "thing" called a singularity.

This didn't really go bang, it was a sudden and enormous expansion so was probably more of a "whoosh".

The wierd thing, is that this singularity existed before the creation of space or time. Therefore, to try and imagine it hanging about in a dark void waiting to explode is natural but wrong. With no space, there was nowhere for it to "be". Also, without time, it had no history to emerge from, so hadn't been there for any length of time. To all intents and purposes, the singularity did not exist until it went boom.

Answer 2

There are minute fluxes in the very fabric of space, when one of these fluxes opens, energy is released which can form matter, however these fluxes do not usually expand and disappear very quickly on the quantum scale. While it not certain, it been postulated that it could be one of these fluxes which did not contract upon itself, and expanded, creating an inflationary universe that eventually led to the big bang. Another theory suggest a super dense core of matter. However such matter would have created a black hole and be incapable of creating the universe. The flux method is favored by many scientists who subscribe to the inflationary universe theory, which while not perfect explains a number of phenomena regarding the creation of the universe. It is also why scientists in this group call the universe "The Ultimate Free Lunch". Because, the universe was created out of nothing as far as our concept of the fabric of space time is concerned.

Answer 3

There was no explosion in a classical sense. The term big bang was originally coined as a joke mocking people that thought it was literally an explosion.

There are lots of ideas as to what caused it to happen, but essentially energy just rushed away from other energy. This rapid expansion of energy, which we now usually call the inflation period is what started off our universe.


A common misconception is that there was matter and things at the beginning of the universe...and all I can say is NO NO NO! There was only energy. E=mc^2, and therefore energy allows the manifestation of matter over time.

Answer 4

Big bang is more of an expansion than an explosion... expansion of space time itself. However, shortly after Big Bang, there was massive matter and antimatter annihilation which released tremendous amount of energy... so I guess that's what exploded after the Big Bang...

Answer 5

well scintists belive the big bang was created after the big crunch. The big crunch was when all the matter in the universe all compressed togeather into a very small and dense thing, the matter blew up and was known as the big bang.

Answer 6

And what caused the explosion? If there was matter there originally then how did it get there? How can an explosion create something? Would an explosion in a vase factory create a glorious vase or in a brick factory a house?
These questions are no easier to answer than' How could God have always existed from eternity?' which is easier to grasp than 'What made God?'

Answer 7

Surmising, I propose we are not in the universe with conventional sense.

1) That we are here by a series explosions.

2) And we are not the only intelligence begins in universe.

But knowing, + proving that are completely different things.

Approximately 13.7 billion years ago, the entirety of our universe was compressed into the confines of an atomic nucleus. Known as a singularity, this is the moment before creation when space and time did not exist. According to the prevailing cosmological models that explain our universe, an ineffable explosion, trillions of degrees in temperature on any measurement scale, that was infinitely dense, created not only fundamental subatomic particles and thus matter and energy but space and time itself. Cosmology theorists combined with the observations of their astronomy colleagues have been able to reconstruct the primordial chronology of events known as the big bang.

Quantum theory suggests that moments after the explosion at 10 -43 second, the four forces of nature; strong nuclear, weak nuclear, electromagnetic and gravity were combined as a single "super force"(Wald). Elementary particles known as quarks begin to bond in trios, forming photons, positrons and netrinos and were created along with their antiparticles. There are minuscule amounts of protons and neutrons at this stage; approximately 1 for every one billion photons, neutrinos or electrons (Maffei). The density of the Universe in its first moment of life is thought to have been 1094g/cm3 with the majority of this being radiation. For each billion pairs of these heavy particles (hadrons) that were created, one was spared annihilation due to particle-antiparticle collisions. The remaining particles constitute the majority of our universe today (Novikov).

During this creation and annihilation of particles the universe was undergoing a rate of expansion many times the speed of light. Known as the inflationary epoch, the universe in less than one thousandth of a second doubled in size at least one hundred times, from an atomic nucleus to 1035 meters in width. An isotropic inflation of our Universe ends at 10-35 second that was almost perfectly smooth. If it were not for a slight fluctuation in the density distribution of matter, theorists contend, galaxies would have been unable to form (Parker).

The universe at this point was an ionized plasma where matter and radiation were inseparable. Additionally there were equal amounts of particles and antiparticles. The ratio of neutrons and protons albeit small is equal. When the universe aged to one hundredth of a seond old neutrons begin to decay on a massive scale

Answer 10

it was a giant pink marsh mallow that exploded and can anyone prove otherwise, not at this time !!!

No one real knows anything about anything prior to the 'big bang', as there is no way (at this time) of even guessing.
