It's just how it works, in general. Also, you seem to think there is some sort of "conservation of volume" principle in general relativity when curvature is introduced, and that's incorrect. | |

To put this another way, if you pinch the pizza so that two pepperonis are closer together, other pepperonis will be closer or further apart as well. | |

In reality when gravity creates a shorter distance between two objects per unit of time - this is exactly the situation of passing warp tunnels but is also the situation on a much smaller scale where two stars simply exist near each other - and there is an increased distance between the two objects from the perspective of another observer what has been observed to happen is the 3rd observer simply observes a greater energy density in the same region of space. We have just described blue shift, we have not violated causality. | |

| Aug 7, 2013 at 6:35 | comment | added | mart | +1 for concisely criticising the warp hype (though I have to think about a few things), but that does not answer the question yet. Is my assumption about a calcuable lower limit to energy demand wrong? Is it the case that creating a warp bubble would not require significant energy, but "just" configuring exotic matter in a special way (so my question would be meaningless in the form I asked and this exotic matter may not exist, possibly can't exist due to your point 1.)? | |
