Re: Tachyons and Sci-Fi
Lots of technology developed by NASA for the space program was sci-fi first, jet packs, CT scans, space stations to name a few.

If I push one end of the rod, theoretically, the other end instantaneously move away from me as well. Actually it won't since in pushing the rod you are using the electromagnetic force between your hand and the rod to do the actual moving and it does not travel faster than light.

Good point! Somehow, that never occured to me before. I guess I'm not as scientific as I wanted to be. Subconsciously, I still view solid objects as really solid objects.

Lam I just happened to be doing some study of my own in physics today.I am trying to catch up on the science I did not have the tenacity to deal with in High School and at the age of 47 I am for some strange reason catching a bug for understanding how the world is put together. The things I have not percieved before continue to stagger me. Today I actually read a new take on something I had heard before but did not really appreciate.
An atom has a diameter of about 10* -8 centimeters. The nucleus has a diameter of about 10* -13. If we had an atom and wished to see the nucleus we would have to magnify it until the whole atom was the size of a large room and then the nucleus would be a bare speck which you could just about make out with the eye,but very nearly all the weight of the atom is in that infinitesimal nucleus. And then to think that the electrons in the probability envelope around this tiny nucleus are responible for the entire array of chemical and biological actions and reactions throughout nature is stunning.From the color of rainbows to the hardness of diamonds, the electrons do all these things. It certainly takes your breath away. I do not have regrets but there are times I wish there had been more time and less responsibilties in my life so I could have pursued these wonders.I envy the young man{and woman} these days in the access to knowledge and real concrete understandings free of superstition and myth.

Well, I'm a little less optimistic than you. many people I have met still seem to think that the sun orbits the Earth.

There is also the flat earth society. I think these people must "act" like they believe this for attention. I just can't fathom people ignoring the facts.

Wasn't gossip supposed to travel faster than light. according to Douglas Adams  Lucy
Bible Search Results "Death & Dead" were found 827 times in 751 verses. Thats a Whole Lotta Suffering

Regarding the size of objects, I learned about the relative sizes of atoms and their component particles as a kid, but at the opposite end of the size spectrum, I had a similar reaction as an adult when I figured out how vastly far apart stars are compared to galaxies. If our sun were the size of a basketball, then the next closest star, Alpha Centauri, would be more than 3000 miles away. But if our galaxy were roughly the same size, about a foot in diameter, then the next closest full-sized galaxy, Andromeda, would be only about 20 feet away. On a relative basis, the stars in our part of the galaxy are like lonely specs in a vast emptiness, while galaxies are within easy hailing distance of each other. --Percy

Yep.
The distances are staggering. Some nebulae stretch hundreds of light years across space. The magnitude is difficult for a lot of people to comprehend.

Almost, but not really.
Douglas Noel Adams writes: (...)One of the problems has to do with the speed of light and the difficulties involved in trying to exceed it. You can't. Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws. The Hingefreel people of Arkintoofle Minor did try to build spaceships that were powered by bad news but they didn't work particularily well and were so extremely unwelcome whenever they arrived anywhere that there wasn't really any point in being there.

Ha!
Thats the funniest thing I ever read...they tried a bad news/ hydrocarbon/lox rocket engine once...but it just backfired with a loud POP and left a smelly gas like sulfer or old boiled eggs.

Ok, new info on the subject matter. What about the bell's inequality? This message has been edited by Lam, 10-04-2004 04:18 AM

Lam There is an article dealing with mesons violation of Bell's inequality at this site. Home – Physics WorldI will try to stay clean away from the issue as it deals with quantum mechanics and is slightly {LOL} out of my league,However I was always curious about the action at a distance idea. I remember reading once that due to relativistic effects a photon travelling at the speed of light,even though it is a finite speed,experiences no passage of time on any distance it travels in it's reference frame.Since space and time are bound at the hip so to speak does information transfer in our frame of reference somehow produce the appearence of action at a distance where none exists for the particle involved? This is no doubt wrong but I need to have some idea of where it is wrong so that I can move on to some other idea.
