This is like saying a guy with a 10cc syringe can hit a guy using a fire hose.. the flows do not allow for the smaller flow to reach the bigger one...
This statement illustrates Billybob's fundamental misunderstanding of the properties of light.
Once created, a photon travels in a straight line until it interacts with a particle of matter. Photons do NOT interact with other photons. Any number of photons can occupy a single point in space, regardless of their direction or wavelength.
A photon emitted from the Earth in the direction of the Sun will be absorbed by the Sun, if there is no other matter to react with along the path. A million photons traveling along the same path in the opposite direction will not affect the single photon headed towards the Sun.
There is no cancelling out in radiation. There are gross flows in both directions, and a net flow that is able to effect change.
The gross flow in either direction can be quantified but not used in isolation because they are happening simultaneously. Two objects at the same temperature are both radiating at each other but there is no change because there is no net flow.
We are talking EM ENERGY not visible light..
But keep talking yourself in circles.. Its funny that you don't even understand basic EM wave emissions and what we call WAVE CANCELLATION. Your hypothetical "photon" is actually Electromagnetic waves. They propagate and they can be dampened much like two hoses facing each other..
But continue to show me you have little understanding of the inner workings of our atmosphere and energy movement.
I never said visible light. I used the generic term 'light'. If you would prefer me to use EMR, consider it done, and respond accordingly.
EMR does not interact with other EMR, it interacts with matter.
A magnetic field (carried by virtual photons) has the ability to polarize some wavelengths of light. Discovered by experiment and measurement, replicated over and over again, know to be true. Does this prove my above statement wrong?
On the contrary. An experiment using a light source, light detector, evacuated tube to connect them, and a moveable magnet to produce the magnetic field provided very interesting results. When the magnet was close to the light source the beam of light was polarized. As the magnet was moved away from the light source the polarization was progressively reduced to nothing. As the magnet started approaching the detector, the polarization reappeared and became progressively stronger. What an amazing result!
Polarization happens when EITHER the light source OR the detector was exposed to a magnetic field! But in the middle, where there was no matter for the light to interact with, the light was unaffected.
