well, with relativity, nothing can be infinitely rigid. even hypothetical bodies within the laws of physics. and 'particle' in physics(and most branches of science to be honest) does not include a huge beam made of iron atoms, made of sub-atomic particles. when you get down to the elementary particles, they don't really have any sor of size in the classical sense. so there is nothing to compress. they are also not composites of smaller particles(we think) like your giant iron beam.

to expand, it would travel at the speed of sound in iron. fast, but nowhere near lightspeed.

looks fine yeah. i'll go with that.

well, the lungs will agitate it enough so it will eventually dissipate in a few breaths. you can still be a bit breathless if doing a strenuous activity even a few hours later though. hand stands get rid of it quicker.

why? what equilibrium? the universe isn't just a big galaxy you know.

well, if infinity is unknown then 0,1,2,3,4,5,6,7,8,9.... > infinity, must be equally unknown as they are equally or less defined.

yeah. pretty much. its okay to do it for a breath or two but if it drops the percentage of O2 just enough over long enough(which is likely with your scenario) then, they could pass out. and if the pass out they'll fall to the floor and if the fall to the floor they'll be even more screwed.

its heavy. heavy things take a while to dissipate.

i wouldn't drop it onto people below you. it has the unpleasant side effect of displacing the oxygen. unless its an open space, they'd suffocate. it'll be sold somewhere. doubt you'll get it in your average practical joke shop though.

oh come on now, you know YT is bad at maths. also, Dy is ferromagnetic at low temperatures.

even after planets form, the volume of matter in the universe in a position to react chemically is miniscule compared to the volume not in a position to react chemically. there may come a time in the universe when the stars are burning out that chemical effects do become the dominant in the universe but that isn't quite yet.

well, of course the official story is still incomplete, they're still investigating it aren't they? the official story won't be finalised till the results are available. our only problem is with those who make outrageous claims that have zero evidence. like the 'fell at freefall acceleration' when it fell at something like 2/3 g type of claims.

you'd still be beating all the alchemists anyway

well, the 1st one seems fine. the rate will depend on the neutron rate. the second would depend on the amount you have. much like criticality. most of the neutrons would likely escape so i doubt it would be self sustaining but it would mean you wouldn't have to fire as many neutrons into it.

well, the atmosphere slows you down. thats why planes have their engines running all the time you're in flight. the spaceshuttle or a sattelite doesn't have any engines that can provide thrust against the atmosphere for very long. so they have to go up to where the atmosphere is so thin it hardly matters. though given enough time (it can vary from hours to millenia depending on altitude) they would still come don due to atmospheric drag.

its quite easy, they just fall in souch away that they miss the ground. lets take the example of your high peak. but lets make it 300km tall. well out of the atmosphere. if you fired a gun it would travel a good distance but still fall back to earth. so, we replace it with a gun with a higher muzzel velocity. this gun will fire the bullet further. perhaps far enough that the earth starts to curve away under it. now, we get an even bigger gun that fires the bullet at around 7.2 kilometers per second. this bullet would hit you in the back if you stood there for about 45 minutes. the bullet IS falling but the earth is curving away at the same rate. that mens it can never reach the surface. there is a minimum distance but that is because of the atmosphere. if the earth was a perfect sphere with no atmosphere then you would only be limited by the ground.

no, but you will notice in the electrostatic examples there is only one type of charge involved.

heh, i seen it in my forensics exam. (it was an introductory class i picked as an elective, i went to approximately 30 minutes of it. got 92% in the exam though)

base 47 of course.

farsight, when you stop posting bumfluff then you will actually be taken seriously. we're not out to get you or any other person with new ideas. science just works on a principal of "substantiate or GTFO".

so that why government bandwidth usage is so high ;P

how are they built into the climate debate? they don't dump anywhere near enough energy into the atmosphere to make a blind bit of difference.

tough it is possible for a compressed gas tank to launch itself over a kilometer. if you do the math it has the energy. though this is unlikely and requires it to launch in a relatively straight line at an elevation of 45 degrees.

in laymans: "Damn thats f****d up"

well, when the perimiter is approaching the speed of light the torque required to keep constant acceleration would increase. i suppose there would be a limit for its rotational velocity.
