| Any ideas on how it would work? Just curious. If we're going to speculate, lets have it be about something cool. I see a lot of people trying to refute relativity. The maximum speed limit of light speed is the issue I would most like to disagree with Einstein on, but it's hard to come up with a good line of reasoning to use. |

i'm not sure if it contradicts Einstein's equations, i thought their implication was that nothing with a mass can travel AT the speed of light
people have often taken that to mean that you can't travel faster, since under circumstances that we can envisage you would first have to travel at that speed before you can go faster - but what if you can jump the speed-of-light boundary and go straight into the FTL bit ?
mind you, i don't know what the physical implication of imaginary numbers is though ...

Well, that about sums it up. Hehe. No, really. Why do you not think so? Because, isn't MarnixR correct? That relativity is purely about entities of mass? Can light travel faster than itself? Of course, I guess the topic is about some object of mass being able to travel faster than light. But, has the question ever been answered if objects of mass can travel at the speed of light? |

| try this; if something already exist and travels faster than light, how could we know it was there? |

Yes, a couple of British scientist came out with the idea of warping space in the 50's, made popular by star trek and other tv shows, however if i remember correctly they estimated that it would take 10 times all the energy in the universe to bend one atom round onto itself.

I think it's possible, but there either has to be a change of rules, or a change of state to make it possible.
Depending on how you look at the nature of particles, you either have to assume that something in our understanding of how things work is wrong, or we're just not in the right spot. What I mean by that is perhaps the key to FTL travel is not trying to move particles or objects through conventional Minkowski space, but by transitioning to another plane or dimension.
Burkhard Heim seemed to think that changing the laws effecting a particle could be done using magnetic fields to, in effect, alter the properties of gravity to allow FTL travel. Sounds good on paper, but unfortunately like all theoretical physics there's some work to be done, and the poor fella kicked the bucket before he could really flush things out.
Of course, there's always a third approach, and that is finding some element or method that allows us to travel FTL in conventional space. Some kind of fuel or manipulation-matter we haven't experienced yet. Maybe we just need to launch Z into orbit and have some fun?  |

I think it may be...
light is energy, right?
Acording to Einstein's E=mc2
Matter can be turned into energy, and energy into matter, there are in essence the same, if we found a way to turn matter in to light energy and back again with the matter in the same state as it was when started...
it mabye possible

Maybe you can go faster than light if you appear to go faster than light, or you speed up the velocity of light, or have infinite energy. Those comply with Einsteins law.

No. I don't think faster than light travel is possible. However, I think that altering the gravity surrounding your ship would make a time dilation field that would let you travel forward in time to your location. However, as I am a newbie so to speak I really have no idea what I'm talking about.

It may be possible if we project the light energy onto an inclinde. The projection will travel faster than the speed of light. |

If the gravity of a star can bend light and a black hole can stop light, could extreme gravity speed light up? Could light or something traveling towards a black hole go faster than LS?

You have to have something lighter than light for it to be able to travel faster than light
or a higher frequency
Thoughts travel faster than light
I'm afraid big bony lumpy masses we call bodies just won't do it
You could always put yourself in a blender and then vaporise yourself into a gas perhaps some other essence emanating from the mix might be able to travel faster than light.
Give it a try and let me know what happens

And here is where a frequently forgotten subtlety of the Special Theory of Relativity comes into play: no signal can travel faster than light.
Now the sweep of your light cone on an incline may be considered to travel faster than light (and you can demonstrate that this is possible), but no information is contained that that cone is taking from one point to another. (Think about it - the information comes from the light source, and making changes at the source will still conduct the signal at no more than the speed of light from the source to the current position of the projection.) |

Gravity propagates at light speed. Maybe we can play gravity and light for faster signal. Oh yeah and we have absence of signal too, which is a kind of signal.
