    What surprises me the most is that objects in medium earth orbit (no atmospheric drag) re-entered within 3 years, only from the pressure of the sun’s radiation.

        Yes, well, except for the “laser” part. And also the part about angry; one needn’t anthropomorphize a natural phenomenon. The Sun is.
