What blows my mind is that star already exploded 3,000 years ago (give or take a few months). I know space is big, but this just hits home how mind-bogglingly big it really is.
I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space.
So the Light traveled already for 3000 light years. The furthest man made object (voyager, 1977, 50 years ago) is currently at the Helipause, just 18 Light-Hours away. Not even a light-day. Much less a light year.
TIL the Oort cloud is thicc
Fair enough, but also it does that every 80 years or so.
Meh, that's the next street in galactic terms. The milky way is 87.000 light year in diameter.
That is crazy. And some stars are probably exploding right now and it will only be visible by our descendants in a few thousands of years. They will look like at it wondering how it was to live in our times.
