What was the size of the universe at the time of the big bang?
The size of the universe at the time of the Big Bang is estimated to have been extremely small, even smaller than a proton. The universe has been expanding ever since the Big Bang occurred approximately 13.8 billion years ago.
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.
How did the size of the universe change?
In the immediate aftermath of the "Big Bang" there was rapid inflation of the universe. That slowed and the universe is now believed to be still, slowly, expanding.
What is the earliest time in the universe that you can directly observe?
The earliest time in the universe that we can directly observe is the cosmic microwave background radiation, which dates back to about 380,000 years after the Big Bang. This radiation provides a snapshot of the universe at that time, when it cooled enough for atoms to form and light to travel freely.
What is the evolution theory of the creation of the universe?
Evolution does not concern the origin of the universe. Evolution is a theory concerning the origin of species--diverse biological organisms--via mechanisms of inheritance with modification. The origin of the universe is best dealt with by the Big Bang theory.
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.
When did time start ticking?
Time, as we understand it, began ticking with the Big Bang approximately 13.8 billion years ago. This event marked the beginning of the universe and the expansion of space-time. Prior to the Big Bang, the concept of time as we know it may not have existed, as time is a dimension that is closely linked to the expansion and evolution of the universe.
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 there any time when there was no universe?
No because time started with the Big Bang.
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 are the essential of the big bang theory?
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.
