The universe simply cant expand at 0 acceleration.
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.

Yes. And actually they have growth acceleration. For example, it would take 10 years for a clone's biological age to be 20.
Acceleration and velocity are vector quantities. Speed, age, and temperature are not.
13.7 billion years or 13,700,000,000 years. Answer2: The Universe may be immortal and have no "age". The size of the universe is such that it would take 16.7 billion years for light to traverse its radius.
It is usually believed that the Universe exists - and has been expanding - for about 14 billion years. It is usually believed that the Universe exists - and has been expanding - for about 14 billion years. The main method for figuring out this age is by observing how fast the Universe is expanding. Galaxies move away from us in such a way that they must have been close together about 14 billion years ago. This assumes the speed didn't change - this is not entirely correct, but you get the idea.
Hello i am minakshi answer is that if we are going to tell the approx age or the evolution of the big bang theory it is13.7 billion years but apart from this if we see then the universe is still expanding after the big bang.may we dont know till when it will expand but there is one hypothesis that when the universe mass will become more and there will be more gravity in the universe it will recollapse again due to its own gravity
The Universe has an age estimated to be about 13.8 billion years.
that portion of the universe that we can see in principle, given the finite age of the universe
If the rate of expansion were constant then astronomers could look at the current location of galaxies and, "by running the clock backwards", work out when they would have all been at one position.
When Einstein applied his General Theory of Relativity to the entire Universe, he noted that his own equations made a Universe of infinite age impossible -- a Universe obeying his laws would either be contracting or expanding, but it could never be infinitely stable. Because he could not accept any Universe with a beginning, Einstein added, out of thin air, a cosmological constant that made his equations "work," in the sense that the Universe could thus be stable. When others noted this was an ad hoc "solution," Einstein replied with near-ridicule. In 1927 Jesuit priest Georges LeMaitre worked out the mathematics of an expanding Universe, and suggested that this would explain an apparent red-shift of distant nebulae (which turned out to be other galaxies, but LeMaitre did not know this at the time). LeMaitre later added to his work by noting that, if his description of our Universe was correct, then there had to be (in his words) "a day with no yesterday." When Edwin Hubble showed that all distant galaxies had a red-shift perfectly in keeping with LeMaitre's predictions, Einstein admitted he had made (again, in his words), the "greatest blunder" of his career.
