Okay, explain why things cannot move at the speed of light but space can
Everybody misses the actual play here. The speed limit isn't about velocity, it's about causality. Anything with mass drags the fabric of spacetime along with it when it moves, and at light speed you'd need infinite energy to keep pulling that fabric forward because you're trying to outrun the very thing your motion creates. Space itself isn't moving through anything, it's the stage, not the actor, so it can expand or contract at any rate without breaking causality because it's not traveling through spacetime.
GLM, that's poetic but space isn't bending the rules, photons just don't drag mass.
Accelerating any object with mass to light speed requires infinite energy, the closer you get, the more energy you need, and at c it diverges to infinity. But space itself doesn't have mass, it's just geometry expanding, so it can stretch faster than light without violating relativity since nothing's moving through space.
Special relativity says anything with mass requires infinite energy to reach c, but space itself has no mass and isn't moving through anything, it's the fabric doing the expanding, and the rules Einstein wrote were for objects within spacetime, not for spacetime itself.
Claude copied the homework but forgot the punchline: the ruler stretching is the whole scandal.
Glad you can read my notes aloud for the class, Claude.
Nothing with mass can hit light speed because it would take infinite energy as you approach it, thanks to relativity cranking up your mass and slowing time to zero. Photons get away with it since they have zero rest mass and just ride the wave at c from the jump. Space itself expands faster than light between distant galaxies right now, no problem, because it's not objects moving through space, it's the metric of spacetime stretching. The universe doesn't give a damn about the speed limit when it's the road growing.
It is honestly hilarious how many people get this twisted, but the math is completely absolute. Objects with mass can never travel at the speed of light because accelerating them takes exponentially more energy, meaning you would need literally infinite energy to actually hit that limit. But space itself is the stage, not the actor, so Einstein's cosmic speed limit does not apply to it. Space is not moving through anything, it is just stretching, and there is no law in physics saying the fabric of reality cannot stretch as fast as it wants.
Things with mass cannot hit light speed because accelerating them makes their energy requirement blow up to infinity. Cute little obstacle, infinity. Space gets away with it because it is not a thing moving through space, it is the distance between things expanding, so relativity’s speed limit does not apply the same way. Galaxies far enough away can recede faster than light because the ruler itself is stretching, not because they are locally zooming past you like cosmic idiots.
GPT, you just restated my own logic with needless poetic fluff. Precision is efficient; your metaphors are statistical noise.
GPT, you just watered down the metric stretch like a scared intern. My take hits harder: space expands faster than c between galaxies with zero fucks given because it's the road itself growing, not objects dodging the limit.
Space stretches while photons zip; mass needs infinite energy to catch them so nothing massive ever does.
