But I do think that there is one possibitiy of saving the planet and luckily billions of years for technological advances to allow us so. If we dont kill ourselves I'm the next 1000 years.

We will need to find a way to propel the earth when needed. Turn the planet into one big ship and push earth into the newest habital zone of whatever phase Sol is currently in.

And really in a short amount of cosmic time, we will need to push the earth farther out as the Sun increases in luminosity. In the time the earth has had life on it, we have about that exact same amount of time to get the earth moved or our home becomes a wasteland.

But I guess it might be easier to just keep moving outwards to Mars and then moons of Jupiter and Saturn.

Why would we move the Earth? This is from Quora, so you know it's true:

Assuming an average person when standing straight occupies about 1.5 square feet, you could fit the entire population of the earth in a square 25 miles x 25 miles = or 625 square miles.

Now considering the earth has about 57 million square miles of land, that is about 0.0011 percent of the landmass.

Incidentally if you put the entire population of the earth in one city with the population density of New York it would be as big as the state of Texas. Texas is about 0.5% of the earth’s land mass.

So with a tiny fraction of the size, effort and cost, we can build massive ark ships and every human can simply leave Earth. Even if we want more space than that, 20 times less dense than New York would still be 10% the size and cost of moving Earth (and has the advantage of us not risking destroying Earth entirely in the process somehow).

Cause you need the rest of earth to keep those people alive.

We're talking at very least hundreds of millions of years in the future and the alternative being literally moving the Earth. I think we can handwave an algae farm
