The conversation between human and AI assistant.
Assume a train travelling in the speed of light and I was running inside the train along the train, is it am travelling faster than light?
Interesting. But what if the train wasn't traveling at the speed of light, but just very close to it?
Even if the train were traveling very close to the speed of light, you still wouldn't be able to surpass that speed. The faster you try to go, the more energy you would need, and eventually you would need an infinite amount of energy to actually reach the speed of light.
