It's easy to understand why the
​ ​
rate of dimming between infrared and ultraviolet light would be different
if it were cause by dust, but it's much more difficult to understand how a
Dyson sphere would
​ do that​
. If a simple explanation can explain something I see no reason for a
exotic one. I see tracks in the snow near a horse farm made by a large 4
legged animal and conclude they were made by a horse.  I could be wrong
they might have been made by a zebra, but I'm probably not wrong.
