Based on the mathematical calculations of Robert H. Dicke, Jim Peebles, and David Wilkinson (astrophysicists at Princeton University), if there had been a "big bang" explosion that created the universe, we ought to be able to detect reflected energy - sort of like "echoes" of the big bang - isotropically, or "from everywhere equally", around the cosmos. We also ought to be able to calculate the time since then by measuring the frequency of that reflected energy.
In 1964, two scientists named Arno Penzias and Robert Wilson were trying to determine the cause of some background "static" noise in AT&T's microwave communications antennas. The background noise seemed to be isotropic, coming from every direction in space equally.
When they all got together, they realized that Penzias and Wilson had discovered the exact sort of background radiation that Dicke, Peebles and Wilkinson had predicted - and that, further, the background radiation was the right frequency to date the "big bang" at about 14.5 billion years ago. Penzias and Wilson shared the Nobel Prize in Physics in 1978.

What is another term for universe?
that portion of the universe that we can see in principle, given the finite age of the universe
The age of universe is 1010 years and the age of mankind is 106 years For how many seconds would the mankind have existed if the age of universe was 1 day?
9075.6
What can be used to date fossils in rocks to give an approximate age.?
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
What is the approximate age of the earth in millions?
4600million years
What is the approximate age of the solar system'?
4.56 billion years
How do astronomes determine the age of the universe?
This is deduced from the expansion of the Universe. Far-away galaxies recede (go away) from us, with such a speed, that they must have been near us about 14 billion years ago.
What are there 92 of in the universe?
That's the approximate number of naturally occurring elements.
When was the formation of the universe?
The Universe has an age estimated to be about 13.8 billion years.
What is the approximate age range of its employees?
42

If the universe was expanding with 0 acceleration what would the age of the universe be?
The universe simply cant expand at 0 acceleration.
What did hubble discover as a result of studying red shift of distant galaxies?
that the universe was in 1904 expanding. this was due to the lack of blue shift, therefor it can be deduced that the red shift in orrcuring within the galaxy.
