This could also go under the space forum, but its significance I think tailors more to this one.

Here's the deal. If you could take a laser pointer and point it at the moon..and see the dot on the moon. If you moved the pointer from one side of the moon to the other, it would seemingly go faster across the surface of the moon than light could travel, thereby breaking the cosmic "speed-limit"

Not so, and here's the answer:

i didnt click your link, but the light from the dot is not actually moving from left to right, its still moving from the pointer to the moon, it appears that it is moving left to right becuase just as the light "shuts off" on one spot it "turns on" again in the spot right next to it, kinda like the scrolling reader board on public busses, they are composed of lights next to each other, turning on and off giving the apearance of the letters moving

Whats the question? And why did you start this topic?

I did click the link and wow, the physicists agree with me.
The movement of the beam can go as fast as it wants, the
speed of the photons remains constant. Therefore the
movement of the beam can exceed the speed of light
because it is not an object.

Whats the point of a topic that doesn't ask a question, and then answers it?

Zaus, this is something that a lot of us have been discussing for some time now here, and something that interests a lot of people.

I found the particular article interesting, and the explanation interesting.

For a second I thought the question foolish, but then remembered that when I was in school I did not know theses thing. Thats why they sent me to school. So that was a very good question, and I know a few Adults who would not have a clue! no.gif
