Physical Science : Does Light Travel in a Straight Line?

[nubian377]

Light possibly doesn't travel at all. It just seems to, because its a signal, whose images are reflected across fields, in a radial manner. Mainstream science will find out this fact soon enough...

GLAD TO SEE THAT STEVE JONES HAS A HOBBY NOW HE NO LONGER PLAYS WITH THE SEX PISTOLS...

Can Light be reflected by anything other then matter, like if there was very strong gravity or a very powerful magnetic field. Would either one be able to reflect that light?

Look close enough at a section of the curviest of lines, and you will see a straight line.

[krusher1977]

What about scattering of light?

[sbrenn]

I'm sorry but light doesn't travel in straight lines. The chance it travels like that is the greatest, but it travels in al directions.

Look up Quantum Electro Dynamics (QED)

This might be a good lesson for primary school or high school but it's all too simple.

If light doesn't travel in straight lines, why does an undiffused light create hard shadows. Yes, light does travel in all directions, but in straight lines. When light bounces off a surface, the light scatters creating diffused light. But that light still travels in straight lines, allbeit in different directions. Don't you agree?

[sbrenn]

If you would squeeze the light through a very small hole to force it to travel in a straight line, you will discover it won't travel in a straight line.

I know it sound odd, but if you really want to learn about this, go to tinyurl (dot) com / nps5j5

Fast forward to around 55 minutes and Prof. Feynman explains it. Although it helps to watch the whole lecture :). It's amazing.

Thanks for the lesson...
