Did Betelguese Replicate Itself?

[kdog]

Betelguese has been know for a long time that it could go supernova, maybe in our lifetime, maybe a million years from now with even a threat of life on Earth being destroyed by a gamma ray burst from it. 

I didn't watch the video yet, just going by memory from years ago researching it. 

I'll see if I can find my old links, in the mean time , don't say that name 3 times or a creepy version of Micheal Keaton might show up.
