IIRC the Aristotle viewpoint was something like, all things are pulled towards the center of the universe, with different elements floating on top of others in the order: earth < water < air < fire (sun) < aether (cosmos).
If you're a video gamer, I highly recommend checking out Odyssey - The Story of Science, an educational game which goes into detail about the "what"s and "why"s of what people believed about the cosmos before modern times, and how each of those theories was disproven.

Energy is not a conserved quantity in General Relativity because the theory is not time-symmetric. Hence the whole "dark energy is increasing" thing.

This also means there's likely a large selection bias.

Reply to comment by AllanfromWales1 in People tend to have more memories associated with older songs and movie clips than newer ones, and they tend to be happier memories as well. People also tend to appreciate content that triggers a memory more by giuliomagnifico
Could it also be selection bias? The older movies I remember are strong memories because, well, I still remember them. The less memorable ones I've just forgotten completely (often forgetting I even watched them to begin with)

> From each's perspective they should arrive at Earth first
What would happen if the winner grabbed a trophy (or whatever) on their way by? Relativity can break simultaneity, but not cause & effect. Thus "local" simultaneity must still be preserved in all reference frames. It's only distant events that different reference frames will disagree on.
> From each's perspective [..] the other would appear to not be moving at all
This would only be true if they're moving in the same direction. But in that case, they can't both be heading towards Earth.
