    equivalent to the energy of a golf ball travelling at 95mph

    So I am curious about this comparison. If this particle had hit you square on the top of your head, rather than the array they built to detect it… would you even know it? Would it kill you? Make you uncomfortable? What?

      It’d obliterate what ever particle(s) were unfortunate enough to be in the way. They’d turn in to a shower of other particles, like sticking your head in a particle acelerator, but all at once.

      It’s highly unlikely all of the energy would go in to you, so it’d amount to a narrow beam of ionizing radiation. Potentially deadly, potentially not. A guy did get his head in a particle acelerator beam when he thought it was turned off. Saw a really bright flash and all. It kinda’ messed up that narrow channel of flesh and he has some cignitive issues as a result.

    They just shot our golden disk back to the library lol. No wonder they got bored by this record. Send some Frank Sinatra or something next. Let’s show them the classics.

    When they say “local void”, do they mean like a cone extending in that direction with nothing behind it or a space with nothing inside it but stuff behind it?

    If it’s the former, what is going on with that?

    If it’s the latter, couldn’t this have traveled from one of the things behind it?
