Basically, an “instant” communication device can create paradoxes.
E.g.
Earth sends mars a instant message. Mars the relay’s it via normal radio to a passing ship/probe moving at 0.99C. That probe then sends an “Instant” message to Earth.
The final message will (depending on alignments etc) arrive before the original was sent. If the message the voids the reason for the original message to be sent then a paradox happens.
You can make similar things happen with any form of FTL communication. C isn’t technically the speed of light, it is the speed of information. It just happens that light has no other speed limiting, and so moves at maximum speed.















I’m pro suicide. However, a lot of times suicide is a permanent solution to a temporary problem.
There should definitely be at least a couple of doctors in the loop for an assisted suicide. There also needs to be a lot more in the way of support for people in that hole. Both the emotional support, and more practical guidance (it’s hard to break out of the cycle when your life is objectively shit and all you can get is “there there, it will get better”).
