Deep Impact, Potential EMP pulse.

Discussion in 'Electronic Basics' started by The Flavored Coffee Guy, Jul 4, 2005.

In spite of NASA's refusal to accept that the pressures resulting from
deep impact's impact on the comet being well beyond those found on the
sun, they've posted no warnings.

They assume that the comet is a rubble pile. As if there isn't any
potential of a comet impacting an meteorite, and producing a solid
core.

When a impact pressure produces a pressure in excess of that found only
on the sun, then the potential of a nuclear reaction involving
non-fissle isotopes becomes possible.

Unplug your computers transient protector from the wall but, do not
unplug your computer from the transient protector.

If the comet is a rubble pile, then only 4.5 tons of tnt will equal it,
and there will be no EMP pulse. If not, unguessable. I've done the
math, and if they hit a hard spot of sufficient mass, then the
pressures will exceed those found on the sun, where raw hydrogen is in
fusion and fision.

A nuclear reaction will generate an EMP pulse. But, that far away, and
the antenna that would recieve the full potential of that power isn't a
small box filled with components, like your computer. But, a birds
nest of wire like the power grid that leads to your house from the
power station.

Hey, crazy conspiracy guy, you get points for originality. A
nuclear reaction! Neat. Impossible, but neat. But you forgot to
war people to put on tinfoil hats to protect their brains from the
pulse.

3. Larry W. JewellGuest

Some poeple never take their little tinfoil hats off, so they don't need
a reminder.

Thanks for the heads-up, Chicken Little.

Well, the Sun has enough pressure in its core to compress 15 million
degree Kelvin hydrogen to over 10 times the density of lead. Even with
such pressure and such high temperature, only a few percent of the Sun's
hydrogen gets turned to helium every billion years.

Somehow, I don't see that kind of temperature and pressure occurring
during "Deep Impact".

Even if both the pressure and the temperature get that great during the
impact on the comet, I don't see any significant amount of nuclear
reaction occurring during the microsenconds that the pressure and
temperature are highest.

1. Consider that even if pressure and temperature get like that in the
core of the Sun (and it appears to me that most proposing that either, let
alone both of these can occur get suggested to wear tinfoil hats), the
amount of nuclear reaction would be miniscule compared to that in a
nuclear bomb. The Sun is expected to take about 10 billion years to fuse
most of the hydrogen that the Sun's core will fuse, and the highest pressure
of the impact will last what - a fraction of a millisecond? I don't see
anything like a nuclear bomb here even if both pressure and temperature
are like those in the core of the Sun.

Difference between the Sun and nuclear bombs:

Nuclear bombs with fusion reactions rely on especially fusible isotopes
of hydrogen (deuterium and tritium), along with temperature and pressure
never achieved by humans except by nuclear explosions.

Other reasons to not worry:

1. This is supposed to happen at a distance a bit over 220 million miles
or a bit over 350 million km from Earth. This is more than twice as far
away as the Sun is. I am unworried enough to be willing to leave my
computer and modem on and connected even if a nuclear bomb was scheduled
to be detonated directly above me at that distance.

2. If you are in the eastern or "midwest" USA or USA's "gulf coast" area,
or in Europe, the comet will be below the horizon at time of impact.
Radio waves that are not limited by "line of sight" do so by being
reflected or waveguided by frequency-selective regions of the Earth's
outer atmosphere.

Snip!

What kind of drugs are you on???

OK, if your theory is good, then you won't mind showing 'the math'
you've done so your peers might prove your theory to be sound.

Personally, I think you speak via your rectal orifice, but who am I to
judge?

12. Larry W. JewellGuest

"almost"? Are you Bill Clinton? The flash was no where near as large as
the comet, and it's just an animation anyway, not a film. Reality show
come to your house for dinner once in a while.

13. KathyGuest

Coffee dude is on bad halucinogenics.

Don K. -- your knowledge of scientific events is very impressive!!! Please,
try to impress upon Coffee dude the effect of bad drugs on his brain
cells....he's not getting the message.

Weren't you predicting some sort of terrible disaster? The whole
thing's over and done with. Where's the fusion explosion? Where's
the EM pulse? They didn't happen, did they? All you got was a
flash from the impact -- which anybody might have predicted.

18. Don KlipsteinGuest

The convective zone is not the core of the sun, and any calculation for
pressure at the highest pressure point here (they don't supply a figure)
is far less than that in the core. In between the core and the convective
zone is the radiative zone, which is thicker than the convective zone.
Obviously most of the sun's mass is surrounded by the convective zone.

Meanwhile, http://www.tqnyc.org/NYC040747/TheSun.htm

says either 250 billion or 340 billion atmospheres for pressure in the
core (gives 2 different figures).

http://www.proeducation.co.uk/pdfs/hires/sun.pdf says core pressure is
about 100 billion kc/cm^2, approx. 100 billion atmospheres.
Gives impact pressures in car collisions. Can you give any figures for
the peak pressure in the comet impact?

http://www.lpi.usra.edu/meetings/lpsc2002/pdf/1875.pdf says the probe has
a mass of 350 kg and was projected to hit the comet at 10.1 km/sec. The
news last night said the probe was about the size of a dishwasher - let's
say 1 square meter.
100 billion atmospheres, a lower estimate of pressure in the sun's core,
or roughly 1E16 pascals, implies a force in the ballpark of 1E16 newtons
to decellerate a probe with a frontal area of 1 square meter.

1E16 newtons divided by 350 kg is a decelleration of about 2.85E13
meters/sec^2. Divide this into square of 10,100 m/sec means that constant
decelleration would stop the probe in .0036 millimeter.
Since the probe's length/depth or whatever probably got squashed by a
good 100,000 times this, I would give a rough ballpark estimate of peak
pressure of a million atmospheres, good chance less given estimates of the
probe to dig up to 80 meters into the comet.

Looks like the peak pressure was around or less than 1/100,000 of that
in the sun's core.
How is this evidence of a nuclear reaction?
Highest pressure cited here is 2 Mbar, roughly 2 million atmospheres or
1/50 of a low figure for the pressure in the core of the sun.

see an explanation how a pressure nearly equal to any pressure mentioned
here is supposed to have occurred during "Deep Impact".

Not really.

To make such calculations would also require you to do a lot of
guesswork and make a few suppositions, which, seeing as the expected
event you predicted didn't happen, would appear to have been flawed.

As usual with many 'UFO reports'.
