And the more energy is stored in this plume, the more rare it is.

So we just have to wait a few centuries before one giant eruption will affect the Earth.

Well...

So when the sun, well, first of all, the sun will brighten up in a billion years to a level that will boil off all the oceans, all the liquid water on the surface of Earth through the greenhouse effect.

So there wouldn't be much left, you know, liquid water on Earth.

It will become like a desert and all life forms will disappear.

Mm-hmm.

from the surface of the Earth.

But within 7.6 billion, by the way, one billion years is about 20% of the lifespan of Earth.

So we just have 20% left before life will not be possible.

But in 7.6 billion years, the sun will die, basically, and will expand.

The envelope of the sun will expand and engulf the Earth.

And it will also engulf the moon.

And so the moon, because of its friction on the envelope of the sun, it will eventually crash on Earth.

The moon came from Earth, but as a result of a collision with a Mars-sized object.

But now it will come back to us after the sun engulfs both the Earth.

Reunited.

And then the combination of the two will sink to the center of the dying sun and will become part of the white dwarf that will be there.

So there will be nothing left of us, nothing left of what we care about on Earth in the long term, 7.6 billion years from now.

And therefore, all of the ambitions that we have about leaving some monuments that will be remembered in the future,
