Over the years I have written four letters to The New York Times.Two of them were published which shows that my view points were taken into consideration.

Will our solar system survive the death of our sun?

Our sun's death is a long way off — about 4.5 billion years, give or take — but someday it's going to happen, and what then for our solar system?


The trouble begins before the death proper: The first thing we have to contend with is the elderly sun itself. As the fusion of hydrogen continues inside the sun, the result of that reaction — helium — builds up in the core. In the final stages of hydrogen fusion, our sun will swell and swell, becoming distorted and bloated — and red. The red giant sun will consume Mercury and Venus for sure. It might or might not spare Earth, depending on exactly how large it gets. If the sun's distended atmosphere does reach our world, Earth will dissolve in less than a day.
