A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

Well the jist of it is in one sentence:
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.
