 And
you thought you were imagining things! The Reuters article below
as reported by a consortium of scientist, suggest the NEAR (near
earth asteroids) in other words, near misses, have increased due
to the Sun, rather than cosmic collisions. Wow, if this holds
true, it would give cause to the sharp increase we have witnessed
in NEO's (near earth orbits) this year.
As most of
you already know, we are at the apex of what NASA calls "Cycle
23". NASA claims we are at the highest point of a natural eleven
year cycle. My research however, suggest we are in a much larger
cycle that supersedes the known eleven, twenty two, and even twelve
hundred year cycle. Many have called this a "Mega Cycle". What
this could mean, according to this new press release finding,
in relation to solar activity with increased asteroid/meteor NEO's,
we are in for a hell of a ride.

I would suggest,
rest assured, you are not imagining things. There indeed has been
a sharp increase in celestial activity, which raises the possibility
or (probability) of a collision with Earth. The question still
stands, not if, but when, and now how big!. Let us all hope the
rock that does come our way will be only meteors in size, and
not kilometers.

LONDON (Reuters)
- Scientists on Wednesday revealed the way meteorites reach the
Earth, saying their paths were influenced more by the sun than
cosmic collisions.
How meteorites,
or asteroid fragments, come to collide with the Earth has been
the subject of scientific debate for some 200 years. Previous
theory held that asteroids, which exist in a belt between Mars
and Jupiter, collided, ejecting meteorites into regions in the
asteroid belt called orbital resonances. Within those regions
the gravitational fields of Jupiter and Saturn acted on the meteorites,
sending them into new paths that might intersect the Earth.
But Paolo
Farinella, who died in March, and David Vokrouhlicky said in the
journal Nature that differential warming and emission of heat
by asteroid fragments in the asteroid belt caused them to drift
into orbital resonances over time.
``Essentially,
the 'afternoon' side of the rotating body (asteroid) is warmer
than the 'morning' side, so the re-radiation of the Sun's heat
produces a small net force across its path,'' Clark Chapman, of
the Southwest Research Institute, Colorado, said in an accompanying
article.
``The simple
billiard-ball analogy of collisions between rocks knocking each
other around the solar system does not stand up to elementary
scrutiny,'' he added. ``It is no easier to 'bump'...objects...with
finite material strengths than it is to hit eggs around the fairways
with a golf club.''
Problems
Of Age And Origin
Farinella,
from the University of Trieste in Italy, and Vokrouhlicky, from
the Charles University in Prague, say the heat differences --
so-called Yarkovsky forces -- explain problems of meteorite age
and origin that have until now confounded scientists.
The collision
model implies the swift ejection of an asteroid fragment into
an Earth-bound trajectory and would result in relatively young
meteorites. However analyzes of Earth meteorites have shown they
are tens of millions of years old.
Yarkovsky
forces cause a gradual drift into orbital resonances over tens
of millions of years and explain why meteorites are so much older
than the collision model would suggest. Collision theories would
also imply that meteorites are derived from relatively few asteroids
which are located near the orbital resonances.
However, studies
of the make up of meteorites on Earth would be more understandable
if meteorites came from asteroids located further from the orbital
pathways, and not just from the few asteroids at the edges of
the resonances.
The drift
theory, which was validated by computer simulations, implies that
meteorites can come from a larger pool of asteroids located both
close to and far away from the orbital resonances.
