That's not true - light always travels at c. The speed of propogation of light through a material is something different than the speed of light - the light rays in this instance are affected by the electromagnetic fields of the atoms. In essence they get bounced around a bit, slowing their progress through the medium, but never altering their actual speed.

People once thought travelling the sound of speed was impossible. I betcha it IS possible to go light speed. Behind every successful man is a woman, behind her is his wife XD |

Well I imagine the previous thoughts about exceeding the speed of sound were not based on any form of scientific thought. Whilst certainly our understanding of the universe is still limited today I still think the ideas behind the limitations of c are extremely well grounded. I'll not bore you with a description why because I probably couldn't explain it very well... But it has cropped up in some unusual places where it has often surprised physicists - the inability the transfer information faster than light in particular. I always think a good way to check if something's right is to see if unexpected results actually come from it - General Relativity is a great example to this, as it predicted all sorts of things like the expansion of the universe and black holes that Einstein himself didn't believe in, but still turned out to be correct according to the theory.

Well, there are things that can travel faster than light... You drop the golden ball. You kick the golden ball. It slides to the west. Suddenly Harry Potter, the apprentice wizard, appears! "That's not how you play Quidditch! are you even listening?" Which direction? (123456789) 4 Harry Potter, the apprentice wizard, is hit by a bolt of acid! Harry Potter, the apprentice wizard, is annihilated. You hear the ecstatic cries of a large crowd! [Edited 1 time, last edit on 6/29/2008 at 20:27 (GMT -5) by Silfir] |

>Well, there are things that can travel faster than light... In 1967, Gerald Feinberg, a physicist at Columbia University, proposed the existence of faster-than-light particles. In their mirror world above the light-speed barrier, tachyons would require infinite energy to slow down to the speed of light. Could be real.

Invisible spaghetti monsters might also be real... There's no evidence for anything like that - we can use Occam's razor to discount any such theories unless something crops up where we need to know about them. Silfir, what travels faster than light? I'd advise you to read over the Wikipedia speed of light article to see common thoughts on this and how they don't affect the light speed barrier.

Heh, I think this discussion belongs back in Any Physicists Out There :-) Darren: I am still waiting for a good explanation, resolving the conflict described in Any Physicists Out There I feel quite confident that the theory of relativity is relative -- that is, a matter of perspective. From each person's perspective (Rocket vs Pluto) time is moving more slowly for the other person. The only resolution I can think of is that the threads are not perpendicular from the rocket's perspective . . . but nobody can explain to me why they would not be perpendicular. P.S. Isn't there speculation that magnetic moments can comunicate faster than the speed of light? In a pair of associated magnetic moments, if one gets set to spin-down, the other is always spin up, regardless of distance, and without delay? Also, doesn't the theory of worm-holse mess with the idea that c is that fastest you can transmit information? |

Darren Grey Registered user Last page view: 4232 days, 10 hours, 46 minutes and 33 seconds ago. |
I believe you're referring to "quantum entangling", which cannot be used to transmit information. When the quantum state of one particle is determined as spin up/down, the other is instantaneously determined too. But it cannot be controlled. Doesn't make much sense either, but that's quantum mechanics for you. Wormholes on the other hand are more science-fiction than scientific theory. Will have another look at the relativity thing some time - can't remember exactly what you were asking about it.

I don't know if this can be considered a paradox, but some time ago I happened upon a new (to me, at least) ice cream flavor: tropical chili (pineapple, orange and chili). Of course I had to test it (since I love spicy food). The ice cream was good, though unfortunately it wasn't very hot (kinda expected since I generally use habanero in my cooking). Now, if I had an ice cream machine I could try making my own custom version of that: orange, pineapple and plenty of habanero. I guess that would make: burning hot ice cream I wonder if such thing should be eaten in summer or in winter ? Sytytä toiselle tuli ja hän pysyy lämpimänä jonkin aikaa.

Is this the correct thread to discuss the forthcoming elections in the USA? |

What exactly is paradox about them? That in any country other than the USA, Obama would've already won? You drop the golden ball. You kick the golden ball. It slides to the west.

Well maybe not paradoxical, but certainly the level of doubleplus ungood doublethink displayed by non-29%ers still thinking about the McCain ticket is.... no hang on, it IS paradoxical dammit... |

How about the paradox that they kept on to Bush for 8 years? That's some scary shit man :/ |

I'm not really what you would consider a physicist, so I might be saying something moronic, but if every action has an equal and an opposite, then what if there was a way to guide light particles and make them collide with other particles? if con is the opposite of pro, then isn't congress the opposite of progress? ~Philosoraptor The gold pieces are engulfed in gray mist. nothing happens. you hear someone counting money.

As I understand it two photons colliding can result in mass being created if there is sufficient energy involved. The resulting mass would then near instantly break down into various sub-atomic particles again. At least that's the girst of what I got from a brief Google search or two, the equations being thrown around makes my brain hurt though. Try searching for "Photon-Photon Scattering" if you want to dig deeper :P Jan Erik Mydland HoF admin |

Faster than light would require as much energy than moving this universe the same amount that you are planning to travel.The theory would be negative mass x negative energy /mass of the universe x energy reguired x speed x just kidding. |
