    Antiwater (two part antihydrogen and one part antioxygen) is repelled by the force of gravity.
    • by Anonymous Coward on Thursday May 22, 2003 @02:28AM (#6013475)
      If only antimatter was repelled by gravity. Antimatter is just normal matter with reverse charge and spin, so it obeys all normal physical laws. So-called "negative matter" would be repelled by gravity, but we don't know if it even exists or can be made.

        Well, that rules out antiwater. The answer, then, is clear. It is antigravity, not antiwater, that makes water go up.

        The troubles here are two:

        1) We have no experimental evidence as to how antimatter reacts to gravity (beond a couple of small ones where the externally-caused experimental error bars render the results statistically meaningless)

        2) We don't know how gravity works. In GR, yes, antimatter has normal mass and reacts normally to gravity. But GR is not the last and final word on how gravity works, and several models otherwise fully consistent with known experimental data allow for anitmatter to be affected to a greater or lesser extent than normal matter by gravity, even to the point of sign reversal.

        Since we have no experimental evidence and several potentially correct theories that give different answers, the only conclusion is that we don't know. The general opinion is that animatter is affected by gravity as normal matter, but we don't know that it is.

          We don't have experimental proof yet, but we have overwhelming reason to believe antimatter fall down just like matter. You can work it out based on hysical constants and conservation of energy in a matter/antimatter annihilation. It is explained in this physics FAQ. [ucr.edu]

          If antimatter is repelled by gravity then you either have a violation of conservation of energy, or physics constants are not constant.

          There can be no doubt, for solid physical reasons, that antiparticles behave identically to regular particles when it comes to gravity.

          First of all, the only relevant physical quantity to determine how something is affected by gravity is its mass (and equivalently, in relativity, energy). That's practically the definition of gravity -- the force one body exerts on another by virtue of its mass. In physicist speak, the gravitational field "couples" to mass/energy. Any force having an origin in some other physical quantity is by definition not gravity.

          Now we have plenty of experimental evidence -- eg from particle accelerators that antimatter has positive mass, just like regular matter. Indeed, antiparticles have IDENTICAL masses to their corresponding real particles. Therefore they must be affected in the same way as regular matter by gravity.

          Secondly, in both relativistic and quantum frameworks, gravity can only be understood if it is always attractive. In other words, mass can only be positive. In quantum terms, this comes out of the fact that gravity must be "spin 2" field. (There's a nice book by Feynman on his attempts to come up with a quantum theory of gravity that explains why it has to be spin 2).

          Thirdly, according to quantum field theory the vacuum is filled with "virtual" particles and antiparticles -- that's the zero-point energy of the vacuum. Now the whole point about the vacuum is that it's the lowest possible energy state. If anti particles had negative mass-energy, they'd be in a lower energy state than the vacuum, which means that they'd be stable compared to the vacuum and would not decay back into the vacuum.
          If that were true, the universe would long ago have filled up with antiparticles...

      Close, but no cigar. The clue is in the article, where it's explained that a "thin later of water" is used.

      In other words, he's using anti-time! By covering the ramps with a thin coating of later (rather than the usual layers of earlier that surround most objects) the water actually flows backwards in time. This, of course, causes its normal downhill motion under gravity to occur retrotemporally, giving the fluid the appearance of syntemporal uphill motion.

      Contratemporal epitaxy, eh? I tell you, that Dyson's a genius!

      More true than you might know.

      Location: Hell's Gate, a set of rapids in the Fraser River, BC, created by an engineering mistake while blasting for the CN (?) rail line.

      Time: Earlier part of the century. Last century.

      Problem: Salmon can't fight their way past the rapids. This is a disaster: the Fraser is one of the "motherlode" salmon rivers. It's an ecological disaster of such magnitude that even those living in the early part of the century recognized it. (Remember that this is a time when burning down entire forests to clear the ground for gold exploration was acceptable!)

      Solution: Assist the fish. Using a big net, scoop the fish up at the bottom of the rapids, raise them tens of feet up in the air, and dump them in a sluice box which inclines down to the top of the rapids. Water is being piped from higher up the river to flood the sluice.

      Result: The fish, dumped into the sluice, try to continue to swim upstream against the sluice water. Consequently, they swim out the high end of the sluice, plummeting back into the river... beneath the rapids.

      Damn!

      (Eventually a weir system of complicated breakwaters and eddies and multi-level entrances and all that was built of concrete. It slows the water enough that the fish can swim against the current.)

    Dyson inventions truly suck!

    I think James Dyson belongs in the permanent Nerd Hall of Fame. His vacuum cleaner is one of the hands-down coolest devices I have ever owned. It represents the most significant advance in vacuum-cleaner technology in decades. See it at www.dyson.com. I would sooner downgrade my Mac than give up my Dyson. Well... maybe not, but I DO love my Dyson (in a geeky way, of course).

    I demonstrate that sucker by turning it on (with the reservoir half full, mind?it uses no bags yet maintains consistent suction even when nearly full?the bane of most vacuums) and inviting the victim to insert a finger in the nozzle. The amount of suction is astounding. On top of that, he wound up having to defend his patent is court for years and finally won out against the big boys of the vacuum universe.

    Dyson is a true genius and he?s a quirky Englishman to boot which is cool in my book. I have a funny feeling he?s not a /.?er, yet I consider him one of the all-time great inventors.

    He is Englands Dean Kamen, methinks.

    This brings back fond memories of an illusion I first saw when I was a kid. I saw it in Springfield Mall. It was put on by a plumbing contractor, or a hot tub installer, or somebody like that.

    It was a faucet, seemingly suspended in mid-air, with an endless supply of water coming from it.

    I marvelled at it for several minutes, pondering how it could be done, yet my child's mind, while knowing it wasn't real, was beyond fathoming any art or science that could accomplish this.

    Leaning closer to inspect it, my suspicions were aroused by the strange apparatus in the catch basin, but I still needed a full explanation from an adult:

    All you do is run a pipe up to the faucet. The pipe supports the faucet. The faucent contains a concavity that directs the water to flow in a hollow cylinder that hides the pipe and completes the illusion.

    You can buy table-top models of this, with yellow-dyed water flowing into a mug of beer.

      The ring was suspended by 4 small clotheshanger-diameter sized wire bars that had the ends running through the walls of the box.

      The walls were freely accessible, and the top was open so you could see inside. No other tubes or wires were evident. As a kid, I suspected trickery.

    This reminded me of something I read in the paper years back, turns out back in 1996 some scientists were awarded [nobel.se] the Nobel Prize for discovering a liquid that actually flows uphill, some sort of special property about temperatures approaching absolute zero that cause liquid to move in a coordinated manner and lack all inner friction. That's the extent of the stuff I can understand, check the article out for yourselves.

      Liquid helium at close to absolute zero. It doesn't flow uphill, it displays enormous capillary effect which can pull it right out of a container.

      Superfluidity of liquid helium (He4) below about 2K (that's 2 kelvin above absolute zero) has been known for a very long time -- since around 1952 or '53 I think. Helium had been liquefied in 1927, but superfluidity wasn't noticed till the 50s.It's a quantum phenomenon. These 1996 Nobel laureates showed

    I have seen sections of water-slides where the water flow actually goes uphill for shorter distances. Then there is the everyday action where water flows upwards inside a pipe. Except we're so used to this, so making a display of it doesn't prove interesting.

    Still, this does look really cool even though it is a trompe l'oeil.

  • "But I'm not telling exactly how I achieve the effect."

    "James Dyson - no stranger to court battles over patents - has presumably taken care of the necessary legal business."

    Imagine that! Apparently he's been granted a patent on this invention but he's "not telling" people how it works. Whatever happened to full disclosure before being granted a patent? You know, advancing the arts and all that? Or is he perhaps going for a different kind of IP protection, like Penrose and his idiotic toilet paper lawsuit

    • You obviously don't understand how patents work, then. The whole point is to NOT disclose them before being granted the patent, at least to the public. Once the patent is granted, it's a matter of public record.

      Look it up if you want to know.

    I remember seeing this ridiculous pop science show that was trying to come up with any evidence to support various bible stories. In one of them the tried to support the splitting of the red sea by showing some researchers who got water to flow up a gradient of decreasingly hydrophobic material (teflon I think). I remember thinking, "Oh yeah, Moses was an expert in poly-flourinated chemistry!" Does this ring a bell for anyone? The teflon gradient that is, not the cooky show.

    It is official; BBC confirms: gravity is dying One more crippling bombshell hit the already beleaguered gravity community when IDC confirmed that gravity market share has dropped yet again, now down to less than a fraction of 1 percent of all garden shows. Coming on the heels of a recent BBC survey which plainly states that gravity has lost more garden market share, this news serves to reinforce what we've known all along. gravity is collapsing in complete disarray, as fittingly exemplified by failing dead last in the recent Dyson comprehensive water test.

    You don't need to be a Newton to predict gravity's future. The hand writing is on the wall: gravity faces a bleak future. In fact there won't be any future at all because gravity is dying. Things are looking very bad for gravity. Red ink flows like an uphill river of blood.

    In Moncton [greatermoncton.com], NB, Canada (where I was born), there is a tourist attraction called Magnetic Hill [tourismnbcanada.com]. It is a really cool experience where you park your car on a hill, and it (seemengly) rolls *up* the hill. This was not designed by "imagineers" or anyone else, it is a natrually occuring illusion... something to do with the way the land grades there in relation to the center of earths gravity. Water also flows uphill there.. totally naturally. Its the only place I know of in the world where this happens.

    "a mile wide, an inch deep and runs uphill," as Lewis and Clark described it.

    It's the Powder River, runs into the Yellowstone to the Missouri. There are places it appears to run uphill because the wind blows the surface backward. It's generally pretty shallow, hence 'the inch deep' and, well, the name.

    There is no link I can point to on the web. Not even Google knows about it. Montana is very unwired.
