How do astonomers measure the distance to nearby stars?
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
Why is it necessary for scientists to use AU to measure distance in space?
It's more convenient for scientists. AU is the distance the earth is from the sun.
The universe is so large that astronomers measure distance between stars instead of kilometers?
light-years, parsecs, and megaparsecs
What are the two measure necessary to calculate average speed?
Total distance traveled & total elapsed time.
You should always measure your following distance in what?
You should always measure your following distance by car length. This will give yourself time to break when necessary without being close to the driver ahead of you.
Does the universe have a definite size?
The universe has been continuously growing since the Big Bang, and there is no way to accurately measure it, so no. Comments: In fact astronomers have estimated the size of the "Observable Universe". They say there's probably a lot more that we can't see. The Universe is about 13.8 billion years old. That gives the maximum distance we can observe as 13.8 billion light years. But while the light from the "edge" of the Observable Universe has been travelling to us, the Universe has been expanding. Astronomers have estimated how far away that edge is NOW. The usual estimate given for the "real" radius of the Observable Universe is about 46 billion light years.
Can you measure the universe?
No.

What is the measure of a regular ten sided polygon?
there is no definite answer
Why is it difficult to estimate the current size of the universe?
It is difficult to estimate the current size of the universe because the universe curves back on itself. (Do not ask how it curves back on itself. The equations are in the Theory of Relativity by Albert Einstein.) Since no one can ever measure the distance to an edge, no way exists to determine the Universe's size.
