"the actual end of the sun means for humanity not death in darkness and cold, but in light and fire, because the red giant called the Sun will eventually grow so large that it will begin to approach Earth's orbit and turn this planet into a global ocean of liquid lava. "

"The Sun will neither die in such a way, nor in such a period, nor can it be fixed as they imagined it. "

"For our sun, it's 10 billion years. We are already somewhere in the middle of this period. So we have about 5 billion years of relatively stable shining ahead of us. "

"even if this whole scenario of restarting the sun actually worked and hydrogen fusion in its interior was reignited, we wouldn't know about it for tens of thousands of years. That's how long fusion energy travels to the outside of the star. "
