Project Universe - Supernovae and Pulsars (3 of 3)

Why would the cosmic rays strike the Earth a few hundred years after the visible light gets here?

@deedubya286 Because cosmic rays are high speed subatomic particles rather than photons, so they travel at slower than the speed of light. See the video at 5:00.

thanks for posting. i learned a couple new things. i had never heard the remaining lifespan of betelgeuse or antares estimated before, also i hadn't heard that orbital velocity of material in a forming star system may determine whether the system is binary, solitary, or with or without planets, but it makes sense now that i hear it.

boring

I disagree. This program explains the interesting physics of how supernovae and pulsars work. Don't expect loud sound effects or clever visual effects - it's not a sci-fi movie.

Exactly. I have seen History Channel's, but this documentary explains things deeply and precisely. We wait for the rest of the episodes.
