If another blue giant explodes in the future will that prove that Albert Einstein's theory E=MC^2 is not a true?
Blue giant is a recent term that is in the popular press, but is not
correct. Giant is used for the advanced stages where helium fusion
is occurring in the core of the star, instead of hydrogen.
If you are referring to a type O or B star, they are short lived (on
the order of tens or hundreds of millions of years), 30 000K
temperature, and much more massive than our sun. They are thought to
end their lives as supernovae. As for relativity, it still holds.
