so john cramer keeps talking about time explosions. the guy is a phd physicist, he's the guy talking about blackholes and CERN back when it started. has a lot say about chronological protection and the laws of relativity preserving time and not allowing you to create a retro-causative wormhole. ie, time-machines. well.. tell that to the mandela effects. someone figured out something or fucked up in the engineering. imagine a future where a starship engine malfunctions and your past changes.
