Weeird!
But awesome.

I would think so: just because you can "see" individual photons, that doesn't mean you can form an image with them. Our eyes do not store/accumulate photons the way a camera does.Loren Booda said:If we can "see" individual photons, is this factor of 1000 probabilistic?

This radiation is supposedly fluorescence from chemical traces on the skin
No it's because you can't see one photon/second from a star on top of 100,000 photons/sec from light pollution.Pinu7 said:And I suppose I can't see any stars here in New Jersey because they went away?

Try being in a mine with your lamp turned off.it never gets completely pitch black anywhere,

I can't see how it could get any darker. :)
It's proof that NASA never went to NJ. The photos were staged in New Mexico which looks a lot like New Jersey if you squinch your eyes up real tight.Pinu7 said:And I suppose I can't see any stars here in New Jersey because they went away?
You can see thermoluminescence quite easily, unroll electrical tape or even tread heavily on some types of sand and you get a surprising amount of light.negitron said:There are still photons, including those of visible light, being emitted from various nuclear decay products, cosmic rays, thermal jitter and neutrino activity.
It means that the human body produces and emits photons, which are particles of light, but in very small amounts that are typically too low to be seen with the naked eye.
Yes, all humans emit some level of light, although it is usually too low to be detected without specialized equipment.
The light emitted by humans is a result of biochemical reactions, such as those involved in metabolism and cellular respiration.
Yes, scientists have developed methods to measure and quantify the light emitted by humans, although the levels are usually very low and difficult to detect.
Studying the light emitted by humans can provide insight into various biological processes and could potentially have applications in fields such as medicine and forensics.
