Nothing goes faster than lightspeed. Why?
It’s because of something noticed over a hundred years ago: Lightspeed measures as 299,792km/sec, whether you’re stationary or doing 299,791km/sec. Every experiment shows it always measures the same.
Weird, but triple checked as true.
The explanation? If someones's speed is close to 299,792km/sec, compared to yours, time appears* to run slower for them. That's not all:
• They get shorter.
• They get heavier.
Close to 299,792km/sec these effects get incredibly strong – and slowing of time slows any acceleration. Things very near lightspeed appear frozen, squashed, and super heavy. They can't accelerate.
Going faster will mean cheating…
*I'm saying 'appears', because to them you're the one that's slow and squashed.
