A quick heads-up on the potential power of dust.* Some scientists have postulated that cosmic dust may have helped end the last glacier age prematurely by causing global warming. Some people try to blame EVERYTHING on dust! Now some other scientists think they have proof that it wasn’t dust’s fault. I’m all for that.
Amongst other pertinent facts: “About 40,000 tons of space dust showers down on Earth each year. And it's been coming down at a steady rate for the past 30,000 years” In fact you’re soaking in it! Dog alone knows how the Americans will respond to the clear and present threat of interstellar dust invasion…

Synchronistically, other researchers believe they have identified the main source of the cosmic dust that gets dumped on Earth – meteoroids. A new study shows that grains of dust left in meteoroid trails are larger than previously thought. As is shown in the picture above, the average grain of cosmic dust is somewhat larger than an apricot.

So the meteorites are in on it too! The sooner the US gets Star-wars off the drawing board and into space, the better! Obviously. Because they’re coming at us from outer space! We have to be ready to stop them or before we know it the entire surface of the world will be smothered by dust.
Oops sorry, I think I started to channel ….something.*
I think that it will be charming when the entire world resembles Terra incognita. Really. Thanks to everyone in the US and Australlia (particularly) for making it possible.
In other things that I didn’t previously know about cosmic dust:
“The detection of cosmic dust points to another facet of cosmic dust research: dust acting as photons. Once cosmic dust is detected, the scientific problem to be solved is an inverse problem to determine what processes brought that encoded photon-like object (dust) to the detector. Parameters such the particle's initial motion, material properties, intervening plasma and magnetic field determined the dust particle's arrival at the dust detector. Slightly changing any of these parameters can give significantly different dust dynamical behavior. Therefore one can learn about where that object came from, and what is (in) the intervening medium.”
*I have been under a lot of pressure to present the public with clearly examples of examplery dust rather than the more allusive and imaginative material that I've been pursuing lately. So here it is.
Now get off my back and get back to work.
*Did I mention that Rapture didn’t happen on the third? MoD’s sympathy goes out to all those waiting for the ride of their lives’.
And now, could they just stop encouraging Armageddon? Perhaps they could join a reading group. I can recommend Oolon Culluphid's 'Where God Went Wrong', 'Some More of God's Greatest Mistakes', and 'Who is this God Person Anyway?'
PS Thanks to Mr W for the shove in the right direction...
