How long would it take for satelite to reach mysterious dark energy?

Answer 1

Dark Energy is a theoretical tool based on the need to explain observations of the Universe.

Current cosmological theories are dominated by the 'Big Bang' theory. When this theory is proven wrong, then the need for Dark Energy will go away. It is theorized because the cosmologists need it to make their mathematical formulae to agree with previously accepted theories. It is like a carpenter who uses a ruler, believing it to accurately measure 1 foot. But he is not taking into account the expansion or contraction of the ruler depending on the ruler's temperature. In a small scale - the carpenter's project - such a tiny change is unimportant. But when the ruler becomes very very long, then such changes in length become unacceptable. At first, the carpenter will believe that some other factor was the reason that his measurements - taken on days with differing temperatures - produced differing lengths. But once the carpenter understand the relationship of his tool to temperature, he can take the temperature into account.

Cosmology is using many old tools as it tries to explain the Universe. But it is too soon to understand all the variables that are producing conflicting answers. Cosmologists make their best guess as to which tools are giving the best, most accurate, most usable answers, and then go on from there.

;-D But every tool that has an unknown error or bias makes finding the truth impossible. That is why there are theories that are almost exact opposites of each other. Such theories can not both be correct. Probably they are both wrong.

Answer 2

As a satelite is a body in orbit around a larger body I would say, at a guess, NEVER

Answer 3

So-called dark energy is the name that's been given to the unknown phenomenon present in our universe that appears to be causing its expansion rate to increase. What it is and where dark energy is isn't known, but it almost certainly fills the universe. If that's true, then you and I and everything else in the universe is currently IN dark energy.
