I appreciate your objections, but, fear we may be alienating curious visitors by 'rigidly' applying forum rules to pedagogical questions. Most such questions are not difficult to address within the context of accepted science. I view this as an educational opportunity, not an annoyance. I personally enjoy the challenge of untangling spaghetti arguments. It keeps me sharper than I might otherwise be.Dale said:Now 29 posts, one full ban, and 2 thread bans.

Indeed, and this is why there's a thread in the first place... Maybe even why there's physicsforums.comChronos said:Most such questions are not difficult to address within the context of accepted science.

No, it is impossible to send a signal faster than the speed of light. According to Einstein's theory of relativity, the speed of light is the fastest possible speed in the universe.
A rigid rod, or any physical object, cannot travel faster than the speed of light because it would require an infinite amount of energy. Additionally, as an object approaches the speed of light, its mass increases exponentially, making it increasingly difficult to accelerate.
No, while quantum entanglement may appear to transmit information faster than light, it does not actually violate the speed of light limit. The information being transmitted is random and cannot be controlled, so it cannot be used to send a deliberate signal.
It is impossible to push a rigid rod faster than the speed of light. Even if you were able to somehow accelerate it to that speed, it would experience infinite mass and collapse into a black hole.
At this time, there is no known way to travel faster than the speed of light. However, some theories, such as the Alcubierre drive, propose methods for achieving faster-than-light travel through manipulation of spacetime. These theories are still purely hypothetical and have not been proven to be possible.
