Faster than light travel can't exist, and a warp bubble is pure speculation. edit: I'll grab the argument I made in a minute. edit 2: Here, now shut up you pseudo-intellectuals. [quote]http://www.nasa.gov/centers/glenn/technology/warp/warp.html [quote]Ever since the sound barrier was broken, people have turned their attention to how we can break the light speed barrier. [u]But “Warp Drive” or any other term for faster-than-light travel still remains at the level of speculation. The bulk of scientific knowledge concludes that it’s impossible, especially when considering Einstein’s Theory of Relativity. [/u] There are certainly some credible concepts in scientific literature, however it’s too soon to know if they are viable.[/quote] The National Aeronautics and Space Administration (NASA) states that it is nothing more than speculation. Not even a mere theory, it's simply an hypothesis that can't even be tested. Here's[url=http://www.nasa.gov/mp4/399027main_Einsteins_Cosmic_Speed_Limit_320x240.mp4] a video[/url] explaining the cosmic speed limit, or [url=http://www.nasa.gov/multimedia/podcasting/EinsteinCosmicSpeedLimit.html]the transcript[/url] if it is inconvenient for you to watch it. [quote] (Julie) [u]Because Fermi saw no delay in the arrival time of the two photons, it confirms that space and time is smooth and continuous as Einstein had predicted.[/u] And it shuts the door on several theories of everything that had predicted that space and time might be foamy enough to interfere with light. [/quote] Let's take a look at your various arguments. (a) Negative energy, it has also been created before. [url=http://www.nasa.gov/centers/glenn/technology/warp/ipspaper.html]NASA on negative energy.[/url] [quote] It is unknown in physics whether negative mass or negative energy densities can exist. Classical physics tends toward a "no," while quantum physics leans to a "maybe, yes."[/quote] Additionally, no human being has synthesized negative energy. You are confused with antimatter. Anti-matter - carries positive energy and mass. Negative matter - carries negative energy and mass. (b) Quantum thrusters Quantum thrusters require negative energy, which can't exist. (c) Warp bubbles are possible. They are not, there is a cosmic speed limit. This speed limit has also been observed, and as I've quoted has been confirmed. (d) We can move faster than the speed of light because the Big Bang did it. http://curious.astro.cornell.edu/physics/the-theory-of-relativity/the-speed-of-light/1013-what-happens-to-a-substance-if-its-speed-is-more-than-the-speed-of-light-intermediate [quote][u]In effect, the universe's expansion isn't really due to galaxies moving "through space" away from each other, but rather due to the stretching of space itself, which isn't governed by the same limits that we are.[/u] Thus, although it's impossible to move through space (locally) faster than the speed of light, and it's impossible for anyone within the universe to send off a piece of "information" faster than the speed of light, it is still possible for the distances between faraway galaxies to increase faster than the speed of light, due to the rate at which the space between them is stretching. This faster than light "travel" doesn't have any effect on the material that makes up the galaxies (for example, their energy does not become infinite in any meaningful sense), since they aren't really moving with respect to each other in any way that they can measure directly.
