Leaks at the LHC were to raise awareness? James Gillies denies but CERN have certainly got people talking. 3000 members in 100 Institutes and given the nature of candidness in particle physics, is it a shock or was it planned? Also, considering that so many have worked together to find supersymmetric particle/s or of course the Higgs Boson, should Carlo Rubbia and Simon van deer Meer get all the credit, NOBEL PRIZE for one example? Any thoughts or even answers?

Looking at electron, there is singularity of electric field in it - its values seem to tend to infinity, but also directions create topological singularity ... This picture suggests that maybe we don't need some additional (out of field) entities for particles, but this construction of field itself is the electron - that particles are some characteristic localized constructs of the field, maintaining their structures/properties - are solitons. Skyrme used such constructions to model baryons, they automatically give particles masses (rest energy), allows for various number of particles because of annihilation/creation, there is corresponding attraction/repelling for oppo…

Will it ever cease to exist? And what about humans, will humans always exist forever? What's the general consensus?

Before the aether thread was closed, the question emerged for me of whether such a thing as a "frictionless superfluid" is actually possible. My reasoning is that it isn't because particles have inertia and thus resist momentum-exchanges during collisions. Therefore any fluid/gas consisting of particles with mass and thus inertia should have friction. Am I forgetting something? Also, in practice how much fluid/gas friction is due to particle-inertia and how much is due to other things, such as electrostatic force among the particles or maybe the shape of particles causing viscosity. I guess a lot would depend on the particular substance in question.

If the higgs boson or mechanism is to give mass to various particles this does not include a photon right? Yet on collision cant photons of some value of energy produce particles that have mass? So that would mean the higgs boson would have had to appear at some point and decay into particles with mass right? Or is it something of a field effect? Simply put if photons are to mediate the electromagnetic field is it on interaction with such a field that you get a point like photon? I am confused greatly and any help would be really neat.

Ok, first of all, I'm in college, I'm not stupid, I've taken physics, so I'm not a total noob, but I have some questions that I came across when I was doing a lab in my calculus class. If a baseball and a ping pong ball are dropped at the same place on earth, with no air resistance, they will fall at the same speed and land at the same time. This is what I disagree with/am confused about. They fall at the same speed because of the earth's gravitational constant (the earth pulls everything equally) no matter what the size/shape/mass of the object is. This is only for earth. On the moon, the gravity is different, thus the constant and the acceleration would be diffe…

Do scientists believe in the concept of infinity? Is infinity proven?

If you have a large cloud of gas of uniform density far from any gravity well, how much density would be required for gravity-well formation to begin? Presumably the cloud condenses under its own gravity as it cools, but is it possible that some part of it could condense more and begin forming a gravity-well that pulls in other particles from the cloud? Also, if a cloud of hydrogen has to cool to condense to a density where fusion can ignite creating a star, how is there enough energy to ignite the fusion? If this post too much resembles my other post on cooling and gravity, apologies. I'm exploring these issues in slightly different ways. If this post can better …

When an oil candle burns, the oil travels up the wick and to the flame. In the same way, a twisted paper towel wil move small amounts of water 'up'. Since that must take energy, (you could put it through a turbine on the way down), I'm wondering where that energy is coming from. My hypothesis is that that minute amount of energy is coming from the heat in the water because every x amount of feet that water falls down a waterfall, it gains a degree. I think this is due to friction, but at least I can assume that when water goes up, it will do the reverse. Any alternative ways of thinking?

I have two wires of same length. One coiled and one straight. Which would offer more resistance and thus, would produce more heat.

Let’s say you have a yo-yo firmly attached to an almost weightless, yet unbreakable string. The string is 1 light year long. You attach the free end of the string to your super strong finger Now you flick the yo-yo into outer space. Speed doesn’t matter, and assume gravity has no net effect on it, so it keeps traveling in a straight line away from you. For one light year the yo-yo cruises along taking up the slack of the string behind it. What happens to the yo-yo when all the slack is taken up? Does it rebound back like a regular yo-yo? If so, then how did it know that the other end of the string is fixed? Information can…

Can anyone who has seen/read "Angels and Demons" tell me whether flying the antimatter high above Vatican City in a helicopter should have made any difference whatsoever, assuming the helicopter could even get that high that fast? I mean, wouldn't the shock wave from an antimatter explosion shatter everything for miles around, including buildings? Not to mention the fact that anyone anywhere near the 'blast' would most likely get fried by a massive flux of high-energy gamma rays rivaling a solar flare in intensity. Did Dan Brown just hugely drop the ball on this one? Or am I missing something?

grab yourself a cd case and something like an empty cigrette packet or simular. hold the cd case out close infront of you so its flat and place the cigarette packet on top. If you now spin around correctly the cigarette packet will not fly off however fast you spin. start slowly and no sudden accelarations Why is this? Am i famous now? Griffiths's circle maybe?

I have a newer theory, if you fly out to space, after a few miles you float in your spaceship once you leave the pull of earths gravity, so theres little/zero gravity in space, but yet the moon which is 200,000 times further away goes simply around. So the question is, is there two types of gravity? Or is mass relevant to gravity, things of different mass fall at different speed/force, but looks the same on earth because you drop something at such a short distance, they "apear" to fall at the same speed/force.

when we say radiation what do we really mean? are we talking about an electromagnetic wave? alpha/beta particles? radionuclides? is radiation that we would be exposed to the same as what would be released by a fission reactor? (weather a 3 mile island situation or a Chernobyl like situation) as the background radiation from other sources? and can someone explain the units that they use when talking about radiation and why if they are EM they are not measured in mW or something similar?

Hey guys, I've always been a really into suppressed information on Tesla and Schauberger and the like, and I just heard about an indie film about a lot of the same stuff that just put a page up for funding on a website called Kickstarter. Anyways, it seems really interesting and I was wondering if anyone had heard anything about it other than on Kickstarter. There seems to be a lot of buzz around in according to my film industry friends. If any of you guys want to read more about it here's the link to the page I was reading about. http://www.kickstarter.com/projects/1172448126/polarity-take-the-power-back

I am trying to determine the feasibility of using a heat exchanger to utilize waste heat from a natural gas burner to heat a large quantity of water. My facility has a nitride process that has three 500 gallon pre-wash baths and a nitride bath of molten salts. The baths have a set point temperature of 130F and the exhaust temperature of the nitride burner is 600F. I'm not sure how feasible this is because heat transfer was never my strong point. If someone could point me in the direction of a design or a company that specializes in this I would greatly appreciate it.

2-3 mile high posts could be built with long cables just like holding up a tent post. these cables are also electrical cables. Aa masive magnifying glass and miror network ontop out in outer space with solar cells. That is what we should be aiming for. Easyier than eternity growing biofuel.

How large does the distance have to be between two massive bodies for an object traveling between them to escape one orbit completely before entering the other? Imo, it seems like the only way for any object to follow a path that's not some type of orbit around another object is for it to crossover to orbit a different object.

OK, so I'm not in the slightest sense a physicist, but I am something of a scientist, and, well... ...no f***ing way. Right?

On a website regarding the physics of solar sailing, I read that "At Earth's distance from the sun, the solar flux, Ss, in space is about 1.4 kilowatts per square meter. This is enough power to run a hair dryer continuously, but not enough to power a car." I would like to know on the surface of the earth what an average range for the number of photons per cubic meter is? I know this is not the typical units of measurement for quantifying light in space. Any help is appreciated.

Hey everyone, Gravity is a constant in both the worlds of the scientist and layman, and as a member of the latter hoping to ascend to the former, I was hoping I could gain a clearer understanding on one of its key natures. I ask, then: Do the forces of gravity affect all spacial dimensions with the same amount of force? It seems likely, as that would explain why most bodies with massive gravitational pulls are spherical. It doesn't really explain the reasoning for ellipses in orbital rotation. And (please recall I'm a high schooler who hasn't taken physics yet) would gravity from a source affect objects, hypothetically, in dimensions impercievable to homo sapiens? …

Alright i was thinking about how cold my hand's get on my motorbike even with thermal gloves on and somehow i come up with an analogy to do with physics thats kinda confusing me. Basically if im on my motorbike doing say 60mph (96km) and inside my body my hearts pumping the good stuff so the blood is getting to my hands at 2 foot per second, would the force of my motorbike going left on the x axis have any effect on the blood which is trying to move at 1 foot per second right on the x axis? im guessing this has something to do with force im thinking if the blood gets slowed down by the opposed pressure while trying to get to the intended cells then this force…

If electrons do not move in classical-mechanical lines of continuous gradations of velocity. I.e. if they don't accelerate and decelerate in a linear sense, how can they be said to have inertia? Does a free electron moving from A to B have the capacity to travel at different speeds according to the amount of force that pushed it? If not, what basis is there for regarding electrons as having mass. I.e. why not just call them a massless particle similar to photons except with charge and unique forms of transit?

I assume that metal molecules vibrate more as they get hotter; but their electrons also must also expand and contract more as they absorb and release more photons. My question is whether both or only one (or neither) of these processes (particle vibration and/or electron level increase) is responsible for the volumetric expansion of metal as it heats up?
