Hands down I think this might be the best thing I ever watched. Movie or television. Maybe cause I'm in this galaxy/ space phase, but these episodes were unbelievable.
I think it all started with a question one day in the water during a surf, when I looked at the sun and wondered does that thing have everlasting recycling energy?
That night before bed I googled it, and learned the sun will eventually burn out , but prior to that will destroy the earth. A few billion years from now that will be a legitimate problem for humans if we are still around.
We can already see it happen in other galaxies.
Most people laugh when I tell them this, and it is funny to talk about. But at the same time insane! Can you imagine living and the sun destroying the earth is a real problem in your lifetime?
Sure you can assume we will live on other planets, but we also assumed by now we would be driving flying cars, and humans would be traveling to other planets and galaxies at this very point in time.
