Ancient Earth Time Machine
Very interesting, the main thing is that later there will still be people who can look at it and not just AI entities with oil can in hand …
don’t worry, in 6 billion years everything will go on its eternal journey in a supernova
It was interesting to see how green/desert areas cycle between being green and being desert!
I wonder what caused then the climate change!
My Hometown was around äquator 20millionen years ago
Really? You need an answer for that
Climate change has always existed on earth. But not as pronounced as in the last hundred years. No wonder, we bang everything in the air for what earth has left itself millions of years time…
Thanks for refreshing my memory, I guess it’s not as good as it was 750 million years a go.
If I were to comment on this now, I might as well make myself a new forum account, because the current one would then be burned in the witch fire.
Why not give it a shot
The Sun will never become a supernova. Unless in some freakish accident, it collides with another star, something that could happen when the Andromeda galaxy collides with the Milky Way in some 4.5 billion years. The number of starts in the sky is going to double on average and there will be a lot of stars flying around. Still, the chance of another star hitting the Sun in this chaos is almost zero, the interstellar space is just too large. The chance of the Sun flying too close to the galactic centre and getting torn up by a black hole is a bit larger.
But if that doesn’t happen, which seems like the most likely outcome, and the Sun continues to exist, as it depletes its hydrogen supply in the core, it is slowly going to expand and become a red giant, its size is going to increase about a hundred times, and its exterior temperature is going to drop significantly so it will appear red. In the process it will not swallow the Earth, but the Earth will nevertheless heat up and slowly evaporate, probably until nothing remains of it. It will look like a huge comet. Jupiter and the other outer planets will probably survive this, but they too will heat up and lose some of their mass in the process. This will last for a couple of hundred million years, then the Sun will shed its outer layers and create a nice, but not very impressive planetary nebula and its centre will collapse into a dwarf star. This may happen once or twice again, on a smaller scale and quicker, eventually leaving behind a white dwarf, a star that is tiny (about the same size as Earth), but extremely dense and hot. It will remain like that for trillions of years, cooling down slowly until its thermal death. No spectacular supernova or anything of the sort, the Sun is too small for that.
@Kresimir you are absolutely right. factually, this is an excellent assessment.
Only in a one-liner it would have missed the joke
Blasphemy. The world is flat. Otherwise I’d spill my coffee.
burns him!! burns him!!
This is cool
Wow! Reminds me of my pet Tiktaalik Murphy! He was a good boy.
Amazing! I wonder how they can map the position of each point basing on their nowadays position.
