Nice eh ?...Coming to a Sun-glass retailers demo room soon !


Ewe've got dark yes ?..you're basic dark is like well black !..void of all light !

But what about brightness ?..is there a limit as to how bright  ' bright ' can be ?

What's the brightest thing out there ?

I think the brightest thing there's ever been was probably the initial start of the Big Bang - it was so bright that even the light was dazzled and couldn't see where it was going for a while.

Allegedly the universe was opaque to light until "379,000 years after the Big Bang", when it became transparent.

It looks like an electron probability distribution of a hydrogen atom ...

Yes - I alluded to this in my post.  However, as I understand it, being opaque didn't mean that photons didn't exist at this point in the BB - they did but just couldn't travel very far before interacting with each other due to the density.  Once the universe had inflated and the density had dropped sufficiently photons could actually travel appreciable distances before interacting with something.

I don't think there's an upper limit for light in vacuum, but in materials (glass, crystals etc) then (even aside from the issue of melting/burning the material) crystals go non-linear when the intensity gets too great (see frequency-doubling or tripling crystals for lasers) and you generate new wavelengths!

As for actually seeing the brightness, I guess the human eye isn't adapted for seeing anything much brighter than full sunlight, and even that isn't very comfortable.


You also need to consider your definition of brightness - the total light output of the sun clearly exceeds anything on earth, however with arcs and discharge lamps etc you can easily make an illumination much brighter than the sun... at short distances. Get out the welding glass!
