    I have a little reflective disc. I will bet you $100 that a reflection of a sunbeam off of it will be exactly the same size (i.e. the same intensity, since it’s not getting any bigger) several meters away as it is a few inches away.

      Try that in your backyard with a small mirror. You’ll find the sun’s reflection expands by about 1% of the distance.
