How long do you think the sun will last such that the earth will become uninhabitable?

Question

I watched a special one time that said the sun was shrinking then went out to professionals who said that your source was not correct and I could not remember the name of the source on television. So I think about this from time to time as it seems to represent the ozone arguments which go to extremes on both sides.

Answer 1

only in a billon more years! The sun is the longest living star in the whole intire universe!

then they would have an ice age!

Answer 2

There will be many other factors that effect the livability of Earth WAY before the Sun undergoes any significant changes. It will continue to burn for a few billion more years, then becoming a Red Giant once its hydrogen supply runs low, then (after a few billion more years), it will become a dense dwarf star.

When it reaches the Red Giant stage, Mercury, Venus, Earth, and Mars would all be either destroyed or toasted to a crisp.

Answer 3

The sun will become a red giant and toast the earth in about
4 1/2 Billion years...
You have nothing to worry about...

Answer 4

First the sun is not shrinking. It's growing. In a few billion years probably will consume the earth or we will have the same "conditions" as Mercur has them today... Hopefully until it will become a supernova the human race will be long gone (otherwise we will be extinguished...). Anyway what you need to know is that it is not shrinjing at all...
