Hi,
Upon thinking further about this, painting it may not actually make much
difference at all, because some of the photons are already reflected, and most
of those absorbed are radiated again more or less straight away,

On Feb. 15, a week from Friday - a decent sized asteroid will come extremely
close to Earth... within the orbit of many satellites, it would seem ...
NASA sez: we've never seen an object this big get so close to Earth.
How close exactly? 17,200 miles.
I would like to think that the Pleiades
Let's face it, they are still trying to track Santa Claus and believe
comets are balls of snow and ice that can pass through the sun's atmosphere
like Comet Lovejoy did and shoot x-rays and sparks millions of miles long.
Will be an interesting year ahead.

Right, about 5% light matter and 95% dark matter/energy. I am not a
doomsday guy, I just think we should realize what we are experiencing. We
have too many phenomenons IMHO. Of course ignorance is bliss and the
dinosaurs probably though those big fireballs looked cool.
