    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?

    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?
