Light is energy with an attitude, sometimes it has mass and behaves like a particle, othertimes it behaves like energy.

>Light is a particle. The particle does not degrade over time. Light is light. Or is it E=MC2 unless the light has travelled over a billion miles, then it E=MC?

>>Hi,
>>4 hours over 1/2 a billion years isn't a great deal of difference. Also, wouldn't half a billion years be sufficient time for the radiation to stop or significantly slow.
>>
>>>>>But in my theory, light that has traveled hundreds of millions of years acts different, and doesn't fit on the same EM spectrum as fresh locally emitted light.
>>>>>
>>>>>It suggests that frequency can drop in really old light, and the wavelength does NOT go up.
>>>>
>>>>How would that be possible? The speed of ANY wave - not only EM waves - must always be the product of wavelength * frequency. This is not advanced math, but simple geometrical reasoning. You can't circumvent that.

>>>Sure you can.

>>>Wavelength and frequency are classical concepts.

>>>My code constitutes a very non-classical physics.
>>>
>>>Remember the wave-particle duality?
>>>
>>>EM "waves" are different than sound waves or ocean waves, or anything like that.
>>>
>>>
>>>> For example, if light goes at 300,000 km/sec, and the frequency is one second, you'll have one wave crest every 300,000 km, since that is the distance the previous wave crest advanced in one second.

>>>>Nor have countless experiments produced any evidence that light goes at any speed but "c".

>>>"Delayed gamma rays from deep space may provide the first evidence for physics beyond current theories."

>>>It seems to corroborate my hypothesis.

>>>>>If anyone can think of a way to test that, it would be pretty good proof.

>>>>It should be possible, in principle, to shine a laser from the moon, or perhaps from a spacecraft further away, and measure any change in frequency. But I guess that first there would have to be a sound theory to justify such an experiment.
>>>
>>>We need to test it at distances where Hubble redshift is observed, hundreds of millions of light years.
>>>
>>>An experiment that involved us emitting the light would have to take hundreds of millions of years to complete.

>>>That's not going to work.
