Ah I see where I mixed things up.
Although I understand that at C "time stops". But since time and space are the same thing, this is the same thing as "all distances are zero". From the point of view of a photon the Universe has dimensions of zero. This is why FTL is impossible; it's not possible to travel a distance less than zero; it's completely nonsensical. If we consider C a "speed" in the classical "speed of sound" the idea of FTL makes sense. But when considering C as a fundamental limit of space-time FTL makes no sense at all.
- Voloskaya 12y agoAnother thing that might interest you: "lets imagine I'm infinity tough and not torn to shreds due to tidal forces" In fact you don't need to be infinitely tough. If you choose a black hole large enough (like the massive black hole at the center of our galaxy), you would just need a space suit and you could go into the event horizon without being pulled apart by tidal forces. You would be absolutly fine (their may be other dangers though...).
