If you want to be "accurate" middle age and now would be the same line (because the last millennia is about 0.33...% of homo sapien's history) and bright future would be pretty fucking long because there's at least a billion years ahead of us for life on Earth, probably more...
because there's at least a billion years ahead of us for life on Earth, probably more...
That's optimistic. With record heat levels, it's going to become uninhabitable for humans long before a billion years.
Why is a bright future assumed?
Sun eventually goes supernova.
It doesn't. It's not massive enough. It turns into a red giant, then collapses into a white dwarf and eventually fusion basically stops.
Alternatively, if we wait long enough we always have the heat death of the universe to look forward to.
I read in this book that there's a restaurant just before that happens where you can bounce back and forth between the death of the universe and the hours before it. So that sounds cool.
Try the steak.
I don’t like food that talks to me before I eat it.
