Buzsaw,
I'm sure nobody but nobody knows exactly how the absense of helium in the sun would affect the earth or perzactly why it's there. You're acting as if we mere humans absolutely, as gods, know everything about everything there is to know. I dooooon't thiiiiink soooo.
In removing the helium, & replacing it with an equivalent amount of hydrogen (based upon the amount of liberated energy during fusion) would have a negligible effect on the sun & it's affect on us, apart from extending the suns life, that is. It would produce the same J/s, & that's all that matters.
If you are asserting that solar helium is vital to human/earthly existence, then I suggest you show it. Baseless assertions are meaningless.
