    Since we’re talking about fears, my fear is that if we just want to die but we basically keep on living via reincarnation. AND YOU ARE AWARE THAT YOU WILL KEEP ON LIVING EVEN IF YOU KILL YOURSELF. that’s my fear.

    I think the shadow part is a but of a lie, because when you move your finger to block the light, light that was already behind your finger at the time still travels to the wall or whatever, in essense if you moved your hand cast a shadow on a wall 500million light years away it would take 500million years for your movements to register

    Darkness don’t have speed
    Because darkness is just there .. light need speed in order for it to move from place to place,,,, but do not mix between shadows and darkness ...because there is a lots of differences between them

    And heres the thing ,we have to backtrack on our road trip when we come to the realization that one of our "facts" are acutely false and then you ask yourself do we really know what we think we know? Or are we always going to be restarting our trip on our voyage to find absolute truths ? And that I think is the real fuel that moves us .

    Sorry homeslice you are wrong about the information thing. information can travel faster than light with quantum entanglement. If i have two entangled particles and i send one to the other side of the universe then I measure mine I can know the position of the other one without having to measure it. That is information.

    Very interesting, Night is the earth in it's own shadow, Easy enough I get it. Actually I never thought about the dark, I thought it was the absence of light just like cold is the absence of heat. So in a shadow is the only dark there is....
