Scientific Controversy

Is there anything faster than light? The intersection between two thing such as scissors have an intersection between the blades. As you close the blades together that point of intersection moves as the intersecting point moves. Does this work with light? As long as information isn't being sent is that intersection faster than light?

Another way to look at it(If you understood the scissors concept), Imagine a pair of scissors and the blades are a light year long. So it takes one light year from one end of the blade to the other end of the blade. Now when those blades close it takes lets say two seconds. Now that point of intersection from the bottom of the scissors to the top took two seconds. The same length but in two seconds.

Re: Scientific Controversy

The atoms in the place you call the "point of intersection" don't move horizontally. It's a bit of a flawed thought experiment.

Also, tachyonic particles are an idea of particles moving ^1+n the speed of light.

Re: Scientific Controversy

So there is a reaaaaaaaaaly long scissor, and when you close the blade, it takes 2 seconds to close?
And light is (I think) the fastest thing for now.

Re: Scientific Controversy

What if you are at the back of a train movung the speed of light, and walk to the front while its moving?   You would have already been traveling at the speed of light, the walking would mean you were going faster than that.

Too large a g-force to even do.

Re: Scientific Controversy

@Jaba - The scissor thing doesn't make sense because the blades are not equal distance apart on all parts of the blades. The time and distance between the bottom of the blades is proportional to the time and distance of the top of the blades.

You are traveling forward.   It's a space train.   Just buy into the concept a small bit, and you get the point.

I understand your idea, but it is completely impossible to do such an event in the real world.

Re: Scientific Controversy

Okay here's an idea

We get this really long pole. We send a guy to another galaxy with said pole and have him transmit messages to Earth by bumping the pole against Earth in Morse Code (the pole is light years long and also indestructible). Therefore information will be transmitted across galaxies faster than the speed of light.

Problem, physics?

it'll move not at the speed of light or faster

Re: Scientific Controversy

It will move at the speed of sound, or however fast sound travels through metal/indestructible material.

Re: Scientific Controversy

The pole thing has already been described many times. Regardless of the thing. Nothing. That has mass can travel the speed of light. It's impossible for anything to travel the speed of light except the speed of light. I know that light has mass to before anyone corrects me.by bumping a pole the pole has to compress the atoms get closer and the electrons have to push the other set of electrons and so forth and so forth. Which can not travel the speed of light.

Re: Scientific Controversy

In a way, darkness can travel instantly but is limited to the speed of light because it replaces light in any area... but darkness isn't matter or energy so it doesn't really count.   If tachyonic whatever thingies are proven to be real, they would exceed the speed of light as they lose mass.

Re: Scientific Controversy

The fastest matter can possibly move does not exceed the speed of light - if you had an object 1ly long and swung it around it would bend at the speed of light (the end of the object will not move for a year)
