640 years wont be possible, that is light speed when explosion we can see it, and you mistake to talk about gamma rays burst when explosion

@Edward Leong 我怀疑你是否听懂了Linvo 所说。他说的是:如果这颗红巨星今天爆发,我们会在640年后看到超新星。他并没有说伽马爆也会 “同时“ 到来(两者之间会有时间差)。以下是我的英译 I doubted if you’ve fully understood what Linvo explained. What he said is that if the red giant explored today, we would see the supernova 640 years later. He didn’t say that the gamma rays will arrive at earth with the same pace (It' could be delayed).
