I have to say I really love reading this type of announcement. I especially love those with invisible matter. I like to dissect them to see if they have a consistent world view and where they are illogical. It is a good thinking exercise and a heck of a lot of fun.
In this case I have no doubt that, as physicists describe particles, they have a handedness that favors the left or that there is a mathematical theory that postulates the possible existence of mirror particles or that CERN would be doing an experiment connected with the existence of such particles. I have no knowledge of any of this, but see no reason to doubt it as part of my thinking exercise. It is only in the application that things get a little hocus pocus. < "If mirror matter exists, then there should exist also mirror stars, mirror planets, even mirror life. > This is where those invisible childhood friends come from. :-) <"Most tantalysing of all, is evidence that our planet is frequently bombarded by asteroids made of mirror matter, causing puzzling events such as the devastating Siberian explosion in 1908 and similar, but smaller recent events in Jordan and Spain," he says. > Absence of evidence is not the same as evidence of absence. In other words a lack of evidence of an ordinary matter impact at Tunguska is not evidence of a mirror matter object. There is NO evidence of a mirror matter object. < some US scientists recently did some modelling and number crunching to determine the fate of the missing comets. They came to the striking conclusion that the number of dormant comets or asteroids being discovered is far too low to accommodate the predicted number - about 100 times too low. So where did they go?> Well let's see, option 1 is that modeling is an imperfect science based upon the most recent but still incomplete knowledge. It incorporates the modeler's biases about which vectors are important and which are not included because they are unimportant or cannot be modeled because of hardware or software limitations or are unknown to the modeler. They suggest a possibility, but don't define reality. Option 2 is 99% of comets are made of invisible matter and that is why we don't see them. <Dr Foot says there is a good case for these missing comets to be made of mirror matter.> Dang! I was sure it was going to be option 1. <In Jordan, April 2001, 100 witnesses on their way to a funeral watched a ball of light streak across the sky at low altitude, break into two, and then slam into a hill about one kilometre away. Again, local astronomers found neither a crater nor evidence of a meteorite; just a patch of scorched earth and burnt trees.> Just like a ball lightning strike. <"These events cannot be explained in terms of a space-body made of ordinary matter.> A quick internet search will provide ample evidence that these events "CAN" be explained in terms of ordinary matter. <If the Jordan space-body was made of ordinary matter it should have lit up a large part of the Middle East. This was not observed," says Foot.> Hmmmm!! No big bright light in Jordan so it is not ordinary matter, it is invisible matter. Big bright light in Tunguska and it is still not ordinary matter it is invisible matter. Where is the consistency? <It is thought that ordinary particles, for example, photons (light particles), cannot interact or couple with mirror particles directly.> Ok so if I take a ball of mirror matter and whack it with a bat then nothing happens to the mirror matter, the bat passes through untouched. <Theory predicts, however that mirror particles have a mass. This means one force that does act on both is gravity, which means we should be able to detect this effect> Ah hah so they do "directly" affect each other, but only for attraction. <Another is the possibility of new forces connecting ordinary and mirror matter. Foot has calculated this force, should it exist, is sufficient to allow interactions between ordinary particles and those of a mirror asteroid entering the Earth's atmosphere.> Oops to explain Tunguska we need another interaction too. It cannot interact, except it does, if needed to prove the theory. <These interactions could allow heat to build up within the mirror body, causing it to explode.> Interesting since heat does not build up in ordinary meteors, it rarely penetrates more than a few millimeters. Breakups are caused by the stress forces generated by trying to push an object through the atmosphere faster than the atmosphere can move out of the way. When the shear forces exceed the shear strength of the object it comes apart. Since the listed causative agent for the explosions is incorrect how valid are the calculations? <It would also make the mirror body visible.> I find this curious, now you see it now you don't. It is almost as if it was thrown it to explain meteor trails by someone who didn't realize that it was the atmosphere that glowed not the meteor itself. <If the events of Tunguska and Jordan are the results of mirror space-bodies, then tonnes of mirror matter might lie hidden just below the surface of these sites, waiting to be found. Nobody has looked," says Foot> Why "hidden" below the surface? Why not on the surface? Or if there is no interaction with ordinary matter why not just gravitationally attracted straight to the earth's core. Nothing to hold it up without interaction unless it is forbidden to occupy the same space as ordinary matter. Of course then a chunk in a puddle would appear as a hole in the water. Maybe that is why it is "hidden" below the surface. The statement that nobody has looked for tons of invisible matter was really funny. "Yes sir professor I looked and I didn't see any so it must be there." On a more serious note I believe in mirror matter because I have a mirror matter meteorite. Every once in a while it falls off the shelf and since I can't see it I wind up kicking it and smashing my big toe. If any body wants a piece I will be happy to chip some off and sell it for $100,000/gm - they are hard to find you know. Just be careful when you open the package because it might slip out and you wouldn't be able to find it. ;-)) Eric Olson http://www.star-bits.com ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
