Distant star's vision of our Sun's future 'death'

[LydiaKlok]

It is thought that our Sun will reach the end of its life in about 5-6 billion years. There was direct evidence that planets can survive the cataclysmic process. Our solar system will be destroyed when the sun dies and turns into a red giant, then turn into a white dwarf. Therefore we will also be gone in about 5-6 billion years, and as of right now all life, as we know it will be gone. That is if we don't kill ourself before then with our emissions causing global warming and climate change. We have found a white dwarf 2000 light years away with a planet orbiting it, which then could possibly give us hope for the future. In this article I read an amazing sentence regarding that if an asteroid got too close to this white dwarf it would simply get ripped apart by its gravitational field strength. This was simply mind blowing and crazy to read, as there is so much out there we don't know about and we continue to try to learn as much as we can as the human race.
