  1. Light Years? on Satellite Loaded With AI For Self-Diagnosis · · Score: 0

    Hah! Proof at last of NASA's hidden warp drive.

  2. Easiest solution on Who Owns Source Code When a Company Folds? · · Score: 0

    Publish the code under your name and wait for someone to sue you. Then appologize and offer to buy the code from them. This is the easiest way to smoke the mysterious "them" out. If nobody sues you, it's yours....and remember, this is not official legal advice ;)

  3. Huh? on Decipher · · Score: 0

    Pulsar? 12,000 year period? Gravity waves from the Sun? I can suspend my disbelief for alot of things, but this is outrageously bad science.
    Pulsars are rapidly rotating collapsed stars with
    an intense magnetic field.....even allowing a mistake and saying that the Sun pulses in and out...this won't generate gravity waves.
    It's just sad.....

    Heh, ya, I don't control the heat in my place..living in a ghett0 basement as I do. My three compys provide ample heating. What's more, I don't pay the power here..

  5. Re:Some Say it Has Already Happened ... on How to Build a Time Machine · · Score: 0

    The mass can come from the time machine itself. For example, in the case of the Tipler cylinder, a time traveler entering the closed timelike curve at one point and leaving at another will draw a certain amount of rotational energy, likely equal to his mass. (*c^2, of course)

    Ah hah! Another Evangelion fan spotted!

  7. This guy's a nut on Time Travel · · Score: 0

    I don't care what the article says. Time travel using this method is simply not possible for a number of reasons. First off, the amount of energy in standard desktop lasers is far too weak to create the necessary effects. Yes, rotating objects or energy currents can have wierd effects on spacetime, even up to the possability of creating closed timelike curves, but it requires neutron star densities, and huge amounts of energy. Secondly, even if he did create the device, he could only (and this is according to the rules of general relativity) go back as far as the time machine's creation. He would still be locked out of the past. Lastly, a discovery like this you would think would be associated with all sorts of pre-print papers. I can only find one from him on the Lanl preprint server .

  8. Re:Random thought: no dimensions, no space on Black Holes and Hidden Dimensions · · Score: 0

    The term dimension merely reffers to the number of coordinates to fix an object's position. In the case of these higher dimensional spaces that we're To locate something in the stringy universe you need both it's large space-time coordinates, plus the coordinates as given by the higher dimensions.

  9. How would they store it? on Orbiting Lasers for Hydrogen Power · · Score: 0

    I wonder how they would extract and store the hyrdrogen. Sounds like it would just be floating free in the chamber..not such a good idea. One spark and boom, quite the explosion.
    Hopefully they've thought the storage and extraction part of this out...

  10. Re:Weapons in Space? No. on Orbiting Lasers for Hydrogen Power · · Score: 0

    Indeed, maybe so, but the energy to power it is provided by solar cells. Free of charge. So all you have to do is have a few efficient solar cells and there you go.

  11. Toshiba laptops=not bad on Lunchbox Computers for Live Music Performances? · · Score: 0

    Got an old Portege laptop which works fine as an mp3 player, sound isn't great out of the speaker, but if you hook an amp to it or something like that it's great

    From all the horror stories about trying to get insurance claims honoured after all this, sounds like getting insurance isn't that much better.

  14. Re:HP28S - Engineering Powertool (once upon a time on HP Calculator Department Closing · · Score: 0

    Me four...the HP28S was the second "supercalculator" I bought. It's an amazing piece of engineering. I actually prefer the clamshell setup to the multi-layered (shift, 2nd function, 3rd function) design of the later models. It still serves me well..it's survived everything. Not much like that is made anymore these days.

  15. Re:A maze of teeny, tiny dimensions all curled... on Man-Made Black Holes Looming? · · Score: 0

    Precicely. Some theorists are saying that the dimensions are actually larger than expected (within the millimeter range) but can only be accessed gravitationally. This is because the things associated with the forces we know about (electromagnetism, strong and weak) are confined to act only in our three "large" dimensions as opposed to the extra compactified ones. I would hope we know a bit more about the physics before we go about trying to create mini black holes, though. Perhaps the extra folded spaces will give them an additional stability we weren't aware of.

  16. Guided and saved on Who Were Your Best Teachers? · · Score: 1

    After several years of bad math teachers I was hopelessly lost...couldn't factor a polynomial if it was to save my life. One teacher, Steve Gorgichuk (I think the first name's right) taught me all the mathematics I'd missed out on and gave me the inspiration to push on further. Today I can play with complex numbers and differential geometry and all sorts of stuff like that. I haven't had the chance to thank him, the next year he won the lottery and retired...

  18. Re:Yeah but they still on Physics Problems For The New Age · · Score: 1
    haven't figured out where my other matching sock goes everytime I do the wash. Seems like a blackhole or something is created with all the water rushing around a metal cylander.

    This is a clear example of the sock information loss paradox. I have found through my years of research that while I start off with many pairs of socks, after a time period, I end up only with mismatched sets. This has lead me to develop a concept known as sockisospin. When socks are exposed to the interior of a rotational heat vortex, the direction of the abstract mathematical sockisospin in Hilbert space is altered, hence destroying the internal symmetry. This symmetry breaking leads to unpaired socks!

  19. quintessence on Physics Problems For The New Age · · Score: 1

    These questions are all pieces of one big puzzle, I think the thing we've got to look for is an answer to how the laws of physics themselves were set down. I've always found that while relativity has a few set of strong guiding principles, quantum theory doesn't. Seems more of a top down than bottom up theory. I think finding these principles will go a long ways to the answers to these questions.

  20. Time for some responsability on Online Rights And Real World Censorship? · · Score: 1

    Post a sign that says people are responsable for their children and responsable for what they look at and that the business has no control over what people view. If people took responsability for themselves and their children this wouldn't be an issue

    Guys, this is nothing. Gnutella and other programs like it will take Napster's place if you want to trade stuff, legally or not. The cat's out of the back, and trying to stuff it back in will only get people clawed.....(hehe)

    Now, if negative energy was an "allowable" number, we would see all kinds of very odd things in quantum mechanics that we do not see, at all,

    Check up on the Casimir effect. Negative energy has been created in the lab. Not much mind you, but enough to know that it exists.

    Is it enough to know.......?
    Je'ne ces't pas!
