WhatsUP! – What happens when the sun finally dies?
I keep having to answer questions about the “end of the world” 2012 Hoax! which is 100% JUNK SCIENCE; so let’s talk about when the Earth will actually REALLY DIE!
In about 3-4 billion years the sun will begin BRIGHTENING and slowly expanding, and our life here on Earth will come to an end. This will not be a catastrophic explosion — but a rather leisurely event happening over millions and millions of years.
The first thing that will happen is Earth temperatures will rise DRAMATICALLY– HIGH ENOUGH to boil the oceans away! Water will only exist in small pools in the deepest ocean canyons. By then all life on Earth– except for some exotic high temperature bacteria will be long dead or moved away completely from the dying Earth.
If the sun continues to expand out to just about the orbit of Earth– even the rocks will become molten. If it actually expands out to and beyond the Earth’s orbit the entire planet will be vaporized. To survive mankind will have long ago moved outward in the solar system to Mars or maybe one of the moons of Jupiter. But the worst is yet to come!
After many more millions of years the sun will puff-off it’s outer layers and shrink into a white dwarf star about the same size as Earth. Although it will still be bright it will be so small that it’s heat will have very little affect– and Mars and the moons of Jupiter will go into a deep freeze FOREVER– with temperatures 100s of degrees below zero.
If humankind still survives in that distant future — they will need to abandon the solar system and relocate among the stars of the Milky Way Galaxy; on some distant unknown planet circling a nearby “young” star.
AND– astronomers from some alien civilization in this distant future, might just look at the solar system in their telescopes and see a Nebula somewhat like the Helix Nebula shown in the above picture… and not know that at one time in the long ago past– a race of “humans” occupied a planet circling the dead star in the center of the SOL nebula.
