Are galaxies moving faster and farther apart?

Answer 1

Yes

Yes they are indeed moving farther apart and if the big bang theory is correct then after billions of years when it's done expanding, it will start contracting and after another billion or zillions of years later it'll become a compact supernova which will become unstable again after some time and cause a massive explosion causing the big bang theory again. You could say we're stuck in a time loop!

Yes, galaxies are moving apart, and they are doing so at an accelerating rate. This is referred to as the expansion of the universe, a phenomenon that was first noticed by the astronomer Edwin Hubble in the 1920s and is supported by a number of observations, including the redshift of light from far-off galaxies.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
