Subject: NASA's Notes Concerning Santa

IS THERE A SANTA?

In the late 1800s a little girl named Virginia asked the New York Times if
there was a Santa Clause.  The reply is now famous. Someone thought it
would be fun to ask the scientists at NASA the same question.
Here is their reply:

No known species of reindeer can fly. But there ARE 300,000 species of
living organisms yet to be classified, and while most of these are insects
and germs, this does not completely rule out FLYING reindeer, which only
Santa has seen.
There are two billion children (under 18) in the world. But since Santa
doesn't appear to handle Muslim, Hindu, Buddhist and Jewish children, that
reduces the workload to 15% of the total - 138 million or so.
At an average rate of 3.5 children per household, that's 91.8 million
homes.
One presumes there is at least one good child in each.  Santa has 31 hours
of Christmas to work with, thanks to time zones and the rotation of the
earth, assuming he travels east to west.
This works out to 822.6 visits per second. This is to say that for each
household with good children, Santa has 1/1000th of a second to park, hop
out of the sleigh, jump down the chimney, fill the stockings, distribute
the remaining gifts under the tree, eat snacks, get back up the chimney,
get back into the sleigh, and move to the next house.
Assuming that each of these 91.8 million houses are distributed evenly
(which we know to be false but for the sake of these calculations we will
accept), we are now talking about 0.78 miles per household, a total trip
of 75.5 million miles, not counting bathroom stops.
This means that Santa's sleigh is traveling at 650 miles per second, 3,000
times the speed of sound.  For comparison, the fastest man made vehicle,
the Ulysses space probe moves at a poky 27.4 miles per second.  The
average reindeer runs at 15 mph.
The sleigh's payload adds another interesting element. Assuming that each
child gets nothing more than a medium sized Lego set (2 pounds), the
sleigh is carrying 321,300 TONS, not counting Santa, who is invariably
described as overweight.
On land, conventional reindeer can pull no more than 300 pounds.
Even granting that "FLYING reindeer" (see first paragraph) could pull TEN
TIMES the usual amount, the job cannot be done with 8 or even 9 reindeer.
Santa will need 214,000 reindeer.
This increases the weight, not even counting the sleigh, to 353,430 tons.
Again, for comparison this is 4 times the weight of the British luxury
liner Queen Elizabeth II.
This combined total weight of 674,730 TONS (with reindeer and the sleigh,
not Santa) is traveling at 650 miles per second (yep, for every second
that goes by, he moves 650 miles) creating an enormous air resistance
which causes heat.
This will heat the reindeer in the same manner as a spacecraft re-entering
the earth's atmosphere. The lead pair of reindeer will absorb 14.3
QUINTILLION joules of energy..... Per second.....Each!
In short, they will burst in flame almost instantaneously, exposing the
next pair of reindeer, and creating deafening sonic booms in their wake
until it all filters down to the last pair.
The entire team will be vaporized within 4.26 THOUSANDS of a second.
Santa, meanwhile, will be subjected to centrifugal forces 17,500.06 times
the force of gravity.
A 300 pound Santa would be pinned to the back of his sleigh by 4,325,015
pounds of force (or 2,163.51 tons) before he too would become vaporized.

CONCLUSION: There was a Santa, but he's dead now.

MERRY CHRISTMAS!!


... to all, and to all a good night!
