What does knowing the rate at which the universe is expanding tell astronomers about the big bang?

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.

∙ 7y agoYou can estimate the age of the Universe from this rate of expansion. Note that this initial estimate assumes that the expansion rate didn't change over time; however, it is known that the expansion rate DID change over time, so additional corrections are required, to get a more accurate age calculation.

Why is the univese expanding?
The universe is expanding because of force of big bang.
What is another name for the big bang?
the expanding universe
What is happening to the universe since the big bang?
the universe is expanding every second...
If scientists say the universe is everything and the universe is always expanding then what is the universe expanding into?
It is not exactly expanding into anything. The galaxies are moving apart from each other, from which we can infer that the universe is expanding. Theoretically, this is a result of the Big Bang, in which the universe began when all matter was compacted into a very tiny sum, and then exploded apart in a very big bang, and as a result is still expanding today.
If there was no universe or plants where did the big bang happen?
It happened in the center of the universe, for which it is still expanding on the universe.
What year did the earth expand in the big bang theory?
It is the Universe that expanded, not specifically the Earth. Earth was formed much later than the Big Bang. The Universe continues expanding, though.It is the Universe that expanded, not specifically the Earth. Earth was formed much later than the Big Bang.

What is the world unfolding into and where is it expanding to according to the scientific community?
This sounds as though you mean the universe, not the world. We believe that the universe has been expanding since the big bang. As to what it's expanding into, that's something of a non-question according to astronomers. If you look around on the internet you can get detailed explanations, including one by Zogg from Betelgeuse on Youtube.
What is the name for the idea that the universe is expanding?
Big Bang Theory
Why do astronomers believe the universe began with an explosion?
the big bang theory
Will there be a new Big Bang when our universe ends?
No, the universe is ever expanding and has no limit to which it can end.
What did Astronomers theorize that the universe began in an explosion called an?
big bang: This is the big bang theory
Why galaxies are going far away and the universe seems to expanding?
That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.
