sigh, knew I'd regret clicking the link. gg next few days
lol yeah sorry man

It gets better and better, some sick rubdowns, and it's quite educational/thought-provoking (honest):
-can you go back and change the past without creating any critical paradox?
-can you go back in time and 'kill your grandfather'?
-can you only go back in time to when they have invented time machines? This is why no one has come back to us.
-you can freeze time at certain points, but it won't affect the lasers because of Special Relativity lol (speed of light is constant)
-'Past' 'Present' and 'Future' are just labels, in Physics there is no 'preferred frame'
-A way of reconciling causality/determinism with human choice/freewill is to posit that at any given time we split off into different 'self-pathways' and live our lives in a million different directions each branching into a million more, you just happen to be inhabiting this particular one. If that sounds ridic then try fitting freewill into a deterministic linear universe. What causes your choices? If they were caused they are not free choices.
Hopefully by reflecting on all of these issues we can feel better about the 3 days we will lose to this ******** game
