Good lord, wow. Talk about your birther bat-boy journalism. We've known for years, decades, Betelgeuse is entering nova stage and that it could go anytime in the next million years or so.

what i don't get is that even if it goes supernova tomorrow, isn`t it many light years away? so it "would take as many years for the light of this event to reach us, right? Wikipedia: "~650 light years away" so wouldn`t we not actually SEE anything for at least 650 years? Some smart guy help me out with this."
while it is correct that it takes that long for the light to reach our Earth, look at it from the stars point- if the star were to supernova next year, it would have happened 649 years ago time wise. this is why scientist are looking at the stars farthest from the Earth, cause they show what the universe was back then. for all we know most of the stars in the sky are already burned out but we are receiving their light just now.
