What was the size of the universe at the time of the big bang?
It was microscopic. At the first moment of the bang the entire universe, that is the entire space-time continuum and all of the energy within it were spaller than an atom.
According to the Big Bang Theory how have the density and temperature of the universe changed over time?
The "big bang" theory is still relatively new. British astronomer Sir Fred Hoyle came up with the term "big bang" as a derogatory term in the 1950's, because Hoyle was a life-long believer in the "steady state" theory of the universe.
What is the earliest time in the universe that you can directly observe?
a few hundred thousand years after the Big Bang
What is 'Pulsating theory' and 'Steady state theory'?
Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.
Which theory proposes that all the matter in the universe simply exploded outward after it was compressed into a small space under tremendous pressure?
The big bang theory does not state that "the universe began with a gigantic explosion." The theory suggests that our universe originated from an infinitesimally small point called a singularity. Since all of space was all localized within this point, the rapid expansion of the universe isn't an explosion. An explosion occurs within space, but the expansion of space itself isn't an explosion. Quite simply, there isn't anything outside of space for the universe to explode into. Thus the "big bang" wasn't big, nor did it go bang. Around the time of the big bang (about 13.7 billion years ago), the universe was much hotter and expanding very rapidly (somewhat analogous to an explosion but by no means an actual explosion).
The universe have a start and end?
The Universe is believed to have had a start, namely, the Big Bang. It seems that it won't have an end, and that it will continue expanding forever. However, a time will come in which there is no more available energy, and therefore, no life will be possible in the Universe.
When did chemical principles start?
At the time universe started: time ZERO, big bang, beginning of the existence of energy and mater.
How old was the universe when the big bang thory happened?
Events in the Universe are often dated from the Big Bang. But the fact is, NOBODY KNOWS what (if anything) happened before the Big Bang. The Big Bang MAY have been the start of time itself; but it is possible that the Universe existed (in some form) forever in the past.
Was there any time when there was no universe?
No because time started with the Big Bang.
How did time start?
The beginning of the universe. the Big bang we "know" when it started (about 13.7 billion years ago see the big bang) but we have NO idea why it started. That's why people invent gods.
Where did time start?
There was no beginning as it has always been.Answer:Philosophers and physicists disagree about the start of time. Stephen Hawking (a physicist) suggests that that even if time did not begin with the Big Bang and there were another time frame before the Big Bang, that information is not accessible to us. It does not exist and cannot be proven. Effectively time starts with the Big Bang some 15 billion years ago.As to where this happened, the Big Bang by its nature is the centre of the Universe.
Was the big bang the first thing to ever happen?
In the current model of the universe the big bang was the 1st thing to happen in the universe since time itself was created in the big bang.
What was the Big Bang theory and briefly?
The Big Bang Theory present the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang promotes that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.

What is a result of the big bang?
The big bang began the expansion of spacetime with great rapidity. The Universe began with the Big Bang. In other words both space and time began at the big bang. The big bang started the Universe from the point t=0.
