Detest

It is just some weird physics indicating that, as time goes on, galaxies get further away from each other. Or may be you have heard the old race car analogy, that galaxies moving apart are like two cars racing away from each other.

I personally detest the race car analogy and prefer the balloon with slightly magical dots. In this scenario, there are dots all over a balloon that is yet to be blown up. When we blow it up in real life, the dots would increase in size. In this analogy, let’s assume they don’t. What we are interested in is how the distance between the dots on the surface of the balloon grows as we put more air into it. Here, the dots aren’t racing away from each other. The balloon is expanding between them, increasing the distance that separates them.
