Yeah the explanations in that page are even worse than any of the ones that I get from actual physicists. Several of the explanations say "FTL is not possible because physics" others simply use equations in place of an explanation.

Well the jist of it is in one sentence:

The net result is that I have transmitted a message into my own past.

Basically, FTL automatically lets you make time machines, and this is bad(TM). It just doesn't make any physical sense, so the consensus is bad things happen (like black holes forming) when you actually push against the speed of light, with very reasonable explanations for why this happens.

The exception is wormholes ,which are theoretically possible "FTL" travel, but only if you are very very careful about where you put them. Otherwise they explode.

Yes this is literally the explanation that comes from every physicist and science explainer I have come across. The problem I have is the how. I do not understand how a message sent real time, as in at the same time on two different planets vast distances away, can go back in time "somehow". Like, I get that the actual answer is ultimately "the math says so" but I cannot adequately wrap my head around the concept.
