OK physics boys; I sincerely appreciate your help with this question of squared,but must query further as usual.
Light from a star is just like an expanding sphere of energy, isn't it?

Not only is it 'like' an expanding sphere of energy, it is that.


Star light is not a narrow beam like a laser as it appears to us, but rather is the same as our sun. Light is emitted from infinite points in infinite directions.
I believe the speed of a light beam can be denoted as C, but should the speed of light from a star be measured like an expanding sphere instead?

Certainly it can be appropriately measured that way. The sun's 'surface', (translatable as an 'event horizon') 'begins', at the parameter of the first light it omnidirectionally projected...


Should star light be measure pi r C squared instead?

No mathematician here, but that may be an alternative standard. I don't see why not.


And while we are on the subject of star light, how is it that the sun emits star light, yet at the same time gravitationally attracts (as has been measured) the star light passing by from a distant star?
If C is C then how can the sun expel and attract light of equal energy or inertia at the same time?

That seems to be one of the cardinal mysteries of gravity, MJA.

And furthermore, I can understand the potential of bending a beam of light, but can not fathom bending light if it were a sphere of energy as the light of a star is.
If the sun's gravity changes the direction of a photon of light coming from a star, it would have an equal effect on the rest.
It would be observationally impossible to measure a change of direction of a sphere of light, when at the same time surrounded by it.
Even though it appears to us as a beam of light being attracted by the sun during a solar eclipse, it’s really is not, is it?
The stuff we mess with!

Well, MJA, there's extant controversy orbiting these issues as you interestingly and cogently present them. Maybe neutralino or someone else can further *field these subjections (*Hee haw) - thought stimulating stuff (A can of wormholes?).
