What is the big bang?

Answer 1

Having sex with someone who has a really big wang.

Answer 2

The Big Bang is a myth of how the universe was created, which is believed to happen 10-20 billion years ago, which involves stars, planets, and the sun exploding and forming what is now our universe. Also, the big bang is sometimes described as when millions of bits of matter was hurled in every direction, eventually joining together to form galaxies, planets, stars, etc. Another thing is that the big bang spread out all the galaxies from each other, and was called the birth of the universe. That is what the "Big Bang" is.

P.S. I know this only because I am a science teacher for high school students.

Answer 3

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.[1]

This timeline of the Big Bang describes the events that have occurred and will occur according to the scientific theory of the Big Bang, using the cosmological time parameter of comoving coordinates. Observations suggest that the universe as we know it began around 13.7 billion years ago. Since then, the evolution of the universe has passed through three phases. The very early universe, which is still poorly understood, was the split second in which the universe was so hot that particles had energies higher than those currently accessible in particle accelerators on Earth. Therefore, while the basic features of this epoch have been worked out in the big bang theory, the details are largely based on educated guesses. Following this, in the early universe, the evolution of the universe proceeded according to known high energy physics. This is when the first protons, electrons and neutrons formed, then nuclei and finally atoms. With the formation of neutral hydrogen, the cosmic microwave background was emitted. Finally, the epoch of structure formation began, when matter first started to aggregate into the first stars and quasars, and ultimately galaxies, clusters of galaxies and superclusters formed. The future of the universe is not yet firmly known.

Answer 6

The Big Bang Theory is that the universe began with an explosion.

Answer 7

The big bang....It is a theory, so to say, which attempts to define the creation of the universe as we see it today.
According to it, all matter was once a super-duper highly concentrated thing, which burst and within a matter of billionths of a second expanded into space.
It has been arrived at by the observation of continuous red shift in every direction that we see. The red shift is a phenomenon in which light being emitted from an object moving away shifts to the reddish side, much like the sound of a passing by F1 car

Answer 8

If your talking about the big bang theory, its the opinion of some that the universe was created by a large explosion.

Answer 9

it is the theory of origin of the universe.... it states that " the universe originated from a big bang... before the universe was a small compressed mass......and then with a huge explosion everything exploded and the universe came into existance"

Answer 10

A Theory about an atomic explosion in outerspace cause by huge meteors, in which landed on Earth causing extinction with the Dinosaurs, due to atmospheric pressure changes, maybe high tides wiped them out. Along with the burning of vegetation life, etc
This theory is irrevelant and has not been proven to be true.

Answer 11

A myth that god did not creat the world. Some time of atomic bang up in space created the earth, then we evolved from apes....not really bright.
