An article in Universe Today provides an interesting look at what might happen to the Earth and the solar system, when the Sun becomes a white dwarf star some 4 to 5 billion years from now. The thinking is based on looking at 4 white dwarfs located within 100 light years from the Sun.

Will This Be The Fate Of The Earth?

I think it depends if humans are around or not. If humans are around the kind of technology by then will enable us to save the sun and the planet from this fate.

and if the aliens get here first, they they probably have that technology already - If they do, then they probably know how to make or break suns or planets.

Sorry, but there's no saving the sun no matter how much technology you have.

If there is a question or problem to solve science can solve it given enough time.

No, not really. We'll never solve, for example, the problem of entropy. It's going to keep increasing, and there is nothing anyone will ever be able to do to stop it.

You do realize that saving the sun would involve adding truly monstrous amounts of raw hydrogen to its core, right? Certainly you can understand the unbelievable technical, physical, and logistical problems of even considering attempting such a thing.

When our sun does its final dance, humans would have been gone from Earth for millions maybe bilions of years. Whether we had gone extinct or relocated for possibly environmental reasons is yet to be played out.

If the fossil record is any indication, Homo Sapiens will have been long extinct by the time the sun goes poof.

For us today that would be impossible. For us a few billion years now maybe not so much. Or they can do what was done in Star Trek. Find a sun that is the exact same mass that has no planets around it and instantaneously beam that sun where our sun is and our sun where that one is. That way our old sun can go out to pasture and become a white dwarf while the new sun takes over keeping our solar system alive and well for a few billion more years.
