When an object (A) casts a shadow and another object (B) is moved to a position about halfway between A and its shadow, so that A’s shadow and B’s shadows are very close to each other, the shadows become distorted. Why is this? Is it related to diffraction?

Light from distant source in observable universe reaches us in 13.75 billion light years; could redshift be caused by ‘tired’ light and not an expanding universe? Light cannot have infinite energy so it must slow or stop?

Is there a theoretical maximum possible light intensity? Why, or why not?

Would it be theoretically possible to deduce the masses and distances of the other planets in our Solar System solely by observing the movement of our Sun? (Looking at the movement of the parent star is one way to detect exoplanets, isn’t it?)
