Sure, that’s all true, but you still haven’t shown that anything can go faster than the speed of light. Time dilation and length contraction conspire to cheat you from doing this.
Did you read what TangoTrotFox wrote? At no point did he invoke any faster-than-light travel. He's just saying that by traveling at relativistic speeds (e.g. 0.99c <= v < 1c), time dilation / length contraction work in your favor. You can travel to systems thousands of light years away from Earth in only a few years (as perceived by you, on your spaceship), all while traveling a bit slower than light itself. Everyone left on Earth will still perceive you taking >1000 years to arrive.
I did, but it was a long post on mobile so I misunderstood their intent. I though that TangoTrotFox was disagreeing with tachyoff, when in fact he was just providing a better explanation.
No, it's correct - but speaking of physics on pop forums is pointless, because of the Dunning Kruger effect.
There tend to be three groups of people:
- Those that accept things at face value, which is quite silly. What I'm saying should challenge all intuitive notions of reality making open acceptance simply bizarre.
- Those that reject things at face value. No better than the first and generally driven by an extremely superficial understanding of physics. As Feynman phrased it, people sipping martinis at a cocktail party and discussing relativity, "Ah yes.. how insightful. Though I think some things may indeed be inherently correct. Mmm..."
- And those with a strong physics background already, to whom you provide no additional value to anyhow.
