Wraithwynd User ID: 669248 United States 06/13/2009 05:43 PM Report Abusive Post Report Copyright Violation | Exotic matter is not the right source of energy for this. To properly 'warp' space one needs to focus gravitons - creating a huge 'gravity' wave field in front of the vessel then have that move forward. Space, and time 'warps' around gravity wells - you just have to make one with out the mass. Matter/energy conversion is the key you create matter from energy to make the graviton field, then immediately (within nanoseconds convert it back into energy - continue doing over and over again the graviton field 'appears' at the same point relative to the ship, but since the vessel is being drawn 'forward' by the gravity (ever increasing its velocity) the spot of space that the matter is created is always further 'ahead'. Make the graviton field large enough physics laws 'fail'. In effect you are creating the gravity field of a 'black hole' without actually creating a collapsar. The 'event horizon' will be out of reach of normal physics - space will warm around that point where light and matter will be able to travel the light speed. BTW Einstein never said that matter can't travel faster than light. He made it perfectly obtuse about matter traveling FASTER than light speed. If you look over the whole body of work you get a 'feeling' that he knew that matter could travel faster than light, but keep us all in the dark. Using a graviton warp field generator to pull the space that short acceleration beyond light speed opens the doors for other methods of propulsion beyond the barrier c.

Einstein's theory of relativity forbids it. In normal space any object approaching the speed of light will increase in mass exponentially, and require an exponential increase in the amount of power needed to propel it forward. Quoting: Anonymous Coward 701929in relativity "c" is instantaneous. "c" is not the speed of visible light. [link to en.wikipedia.org] plenty goes faster than visible light. ultraviolet, x, and gamma rays, and beyond...it is infinite. Einstein new this, and had to define "c" as instantaneous, which is why nothing can go faster than instantaneous...or it would go backwards in time and bend space-time. |

There is only one demand to be made of the definition of simultaneity, namely, that in every real case it must supply us with an empirical decision as to whether or not the conception that has to be defined is fulfilled. That my definition satisfies this demand is indisputable. That light requires the same time to traverse the path A —> M as for the path B —> M is in reality neither a supposition nor a hypothesis about the physical nature of light, but a stipulation which I can make of my own freewill in order to arrive at a definition of simultaneity.” -Einstein [link to www.bartleby.com] |

You don't really understand that pic you posted do you? It says nothing about the speed of the different types of energy. It shows only frequency and wavlength. EVERYTHING on that diagram travels at the speed of light. Just when you think batshit crazy can't get any crazier Emily goes and ups the ante. |

nomuse (NLI) User ID: 700752 United States 06/13/2009 08:28 PM Report Abusive Post Report Copyright Violation | The problem is, anything that makes a decent spaceship, makes an even better weapon. Let me break this down a little. Space is big, as the Douglas Adams quote goes. Distances between even the planets of our Solar System are vast, and gravity is a bitch. The amount of energy you've got to put into the Space Shuttle just to get it up to a dinky near-Earth orbit and do some work is that amount that gets the shuttle moving at about 7.8 kilometers per second (add about another 2 kips worth for gravitational and atmospheric drag before you get there.) As comparison, a military rifle sends a round downrange at a mere .9 kips or so. And kinetic energy goes up by the SQUARE of the velocity. If a rifle bullet hit you at the speed of the Space Shuttle, it wouldn't make a hole; it would disintegrate you, and blow up the room around you as well. And that's just for dinky low-orbit stuff. Now imagine the poor science fiction writer who wants to have some cute little two-seater runabout a couple can take out of their driveway for a romantic dinner on Mars, and return in time for work on Monday. For the kind of quick, inefficient travel you'd want for a piece of fiction, you need a lot of power contained within that ship. And to make it a simple "turn the key and fly into space" it all has to be packed into the gas tanks. Our little two-seater runabout contains more energy than a Saturn V stack. The little engine puts out, over the romantic weekend, something comparable to the electrical usage of the entire East Coast of the United States. In summer. (Yes, probes like Voyager get to the outer planets on a lot less juice. But they do so with highly efficient transfer orbits and finicky little gravitational assists and a hell of a lot of time. If your space-hopping villain has just kidnapped the heroine's boyfriend, and she is charging off to the rescue on her own ship, you really don't want her to spend the next twenty years in transit!) So the first problem is that this plot-handy little starship could, in the wrong hands, be a devastating weapon. Point the nose at New York instead of Mars, and you would take out a lot more than a couple of measely skyscrapers. All it takes is one interstellar trucker falling asleep at the wheel, and the incoming Exxon Valdez strikes Earth like the Chixslaub meteorite. So good-bye to privately owned spacecraft, space-cabs, romantic space tramp steamers with drunken captains and a single greasy mechanic. Those craft are going to be under more locks and regulations and permissive fire links than a nuclear warhead. The second problem is, if you can put that kind of power in a Space Prius, just imagine what you could put in a missile if you wanted to! And that's just dealing with solar system distances. Try to get to other stars, and things get far, far worse. (And there's the not-so-little problem of causality that also rears it's head when you start going faster than light...) |

zepa User ID: 23967300 United Kingdom 09/18/2012 06:19 AM Report Abusive Post Report Copyright Violation | imho they are looking at the whole thing the wrong way they are looking to move faster the real problem is the time it takes if you could remove yourself from time speed=distance yes its a time machine but imho its no crazier than talking about traveling at the speed of light the added bonus of removing yourself from time would be not having to think about even grains of dust hitting you at light speed(im guessing that not in time =not in space time) as far as physics can say is time slows the faster you go but what if it also slows as you gain energy (time is an expression of energy) |

That's exactly what the movie "Event Horizon" is all about! The only difference is that the warp drive device is inside the ship. Perhaps is what the "scientists" behind this warp drive idea, want to do: Suck the entire Earth into a black hole and send it to some hellish dimension.
