Due to popular consensus, we believe there should be a place for these kinds of things. Feel free to discuss or ask anything with even loose regards to physics.
What's the best form of 'faster-than-light' (either shortening the distance or somehow ignoring physical laws of the universe) travel? I.e. Space is contracted in front and expanded behind. This means the distance is shortened. Star Trek Example of "Warp Drive":
I'm not sure if I'm just acting stupid from lack of sleep, but if you consider the distance from the view of an outside observer and the time it takes you, the combination of time dilation and length contraction should allow you to travel faster than the speed of light if you consider it that way.
A wormhole for example would seem to be more precise and better at 'point to point' travel. Though "warp drive" has the advantage of being able to be used for 'normal flight' in terms of directional movement.
Wha.....while close to light speed is theoretically possible, practical use of it would be pointless. You'd end up thousands if not millions of years in the future traveling any serious distance. Not to mention that still limits travel to relatively close to our solar system. The closest star that isn't our sun is 4 light years away. That's 4 years of time relative to the traveler, any further distance and you're talking about cyrostasis just to be able to live through a trip to a star say 100 light years away. (which still isn't all that far relatively speaking) Only practical theory of long distance travel is through wormholes. I believe in the theory of black holes as worm holes. Black holes are so massive, they bend space so much (like draco's pictures) that a path is formed between two black holes. I don't really believe in Hawking's current viewpoint that wormholes exist everywhere and are tiny. These wormholes are how he postulates how gravitons propagate through time and space.
I'm not sure if it's the same or i'm really high, but you're going to have to explain that in a bit more detail, perhaps with a few relevant links to info Also , C, speed of light is the figure for a vacuum. C decreases as the vacuum gets less and less, or as you start to fill up the space with material. The speed of light for a specific material is also a constant. Cherenkov Radiation is emitted when charged particles exceed C, speed of light, as they pass through a material. So if a particle can surpass the speed of light in a liquid, can a particle surpass the speed of light in a vacuum? You also have the Scharnhorst effect, although it's not very likely.
