Not only that, but think of how rarely those particles even hit the earth's atmosphere and burn up. A good shower is anywhere from 50 to 140 an HOUR. Do the math; it's not that hard. That translates to anywhere from less than one per minute to a little over 2 per minute.


To quibble just a bit but that's only for a single observer seeing one little bit of the night sky from his/her location. Maybe a 50 mile radius?

Does not invalidate my argument, because it's the spacing between the particles that counts. From any one point on the earth the stream averages out to be more or less the same density, changing slowly over time, but not radically.

The speed and spacing of meteors in a shower suggests many miles of separation, on average, between particles smaller than a sand grain. Yes, sand grain. That's the size of the particles we're talking about. Spread out evenly the sand grains you can hold in one hand, over the entire southern half of California, and that's the density of particles. They only seem dense due to perspective; a very thinly spread material will look very dense if seen from a long enough distance.
