These aren't really paradoxes but are not worthy of their own thread, so I'm sticking them in here.
We don't really touch anything. Burn yourself on a hot coal, stroke a cat, cut your finger off with an axe, swim in the sea, you haven't touched any of those objects. What you really feel is electromagnetism. Light is invisible. Shine a laser through a vacuum, it's invisible. All we can see are the things light strikes, not the light itself. Those battles in space full of laser beams in films like Star Wars and Star Trek, it wouldn't look like that. |

If you're traveling the speed of light and you shine a flashlight ahead of you, what happens to that flashlights' beam of light?
Does light have the same principals of velocity that solid matter does?

It's a good question. My understanding is the flashlight wouldn't emit a beam of light and that neither photons nor particles of matter can exceed the speed of light. However, recent research seems to suggest that information (in the experiment in question, it's information shared between two entangled photons) can exceed the speed of light. And that begs the question what is the information their sharing made from?
Here's an article on it: http://en.wikipedia.org/wiki/Quantum_entanglement If we could somehow understand it and employ it to move real life matter, interstellar travel may become a reality. Last edited by Mr. Charlie; 11-06-2013 at 10:41 AM. |

I am driving my car at the speed of light and I turn on my headlights. What do I see?
Seems we're both wrong. The person travelling (close to) the speed of light would see a normal beam of light but it wouldn't exceed the speed of light. I love science but I never really know what I'm talking about because all I can do is repeat second hand information and form a vague and shadowy understanding based on the experiences of others, never knowing whether what I heard or read is true or even likely to be true. But then again, I think everyday life is a bit like that too, whether we realise it or not. |
