Re: Meteor increase worries scientists
Hello all,
Regarding the perception of an increase in bolide sightings, it may or may not
be factual and it may or may not be significant. There is such a thing as
random clustering and this list has contributed to everyone's awareness of
incidents. Only time will tell.
If you want something to ponder, consider this: Michael Ramphino, who, at
least in part, discovered the possible 30 million year cycle of major impacts
has an excellent article in the current Planetary Report from The Planetary
Society. In the article he points out that one possible cause for the cycle is
the solar system moving up and down through the galactic lens as it rotates
around the Milky Way, which causes large cometary objects in the Oort cloud to
be perturbed inward towards the sun. IF all this theory and speculation were
true, the solar system has "just" passed through the lens a few million years
ago, and all those perturbed cometary objects would be showing up right about
now (give or take a few hundreds of thousands of years).
It's all theory, of course, but it's interesting timing in terms of species
development.
