If the ash cloud is at 55,000 ft, why can't the planes fly at, say,
40,000 ft instead?

What happens to solid matter in the air?

As I understand it, the news reported that the particles were being
blown south east and were not falling.

Most of it might not be falling, but some has to, unless gravity has been
switched off.

I believe the ash is actually at between 20 and 30k feet although the
maximum reported height has been 55k. Most jets operate at between 25k and
41k so they're actually going to be in the ash band or have to get through
it neither of which is a good idea for aircraft.
