If you can stand say 500 miles away from the Sun how bright would it look?
What im trying to get at is does brightness just get more and more whiter? Like increasing the watts in a lightbulb?
What is the limit as how bright something can get? What would it look like if you didn't go blind.

Brightness is in effect a measure of amount of light energy per unit area. If this has a limit, it is only the limit imposed by the maximum density of energy that space-time can withstand- if there is one. The human eye, or any other camera, can only measure light intensity up to a certain limit. Beyond that limit it simply won't register any more, and may sustain damage. 'Whiteness' on the other hand occurs when there is a mixture of light of different wave-lengths. If there was just one wave-length, the light would be monochromatic, (one colour) but it would still be bright. Like looking directly at a laser beam for example. (Do not look directly at a laser beam).

Every time you cut the distance between you and a light source in half, the object looks 4 times brighter . If you were 500 miles away from the sun it would be very very bright. You can do the math.
