[QUOTE="Umbran, post: 7766943, member: 177"] Note that "low speed effects" means "every speed generated by humankind outside of a particle accelerator". You were referring to new science of the form, "everything we know is wrong". My point is that that doesn't really happen. In modern science, the things we know... we know. We observe them up, down, and crossways. We measure and remeasure and confirm. New science can't change what we have already seen! Any new understanding of the universe [i]must be consistent[/i] with old understanding. F'rex: We have observed gravity's scaling with the square of distance on the scale of mountains to the scale of galactic clusters. Any new idea of gravity must be consistent with those observations, or the new idea of gravity is clearly wrong. New things in science don't say, "You were wrong." They say, "Oh, and also this..." New science adds to old, it does not replace the old. So, any form of FTL that we get must still be consistent with everything else we have ever observed. And that puts some very restrictive boundaries on it if it does exist. You are being way too vague here. In general, determining a value for G with greater than 0.1% precision has proven difficult. But that *IS NOT* the same as saying it is variable on things we didn't understand. Claims that G varies are, as yet, [i]entirely speculative[/i]. G has been hard to nail down, and ego tends to make us speculate that this is the fault of G, rather than a fault with our experiments to measure it. "that much" isn't really all that much, though. We don't need to know much to make FTL travel a highly questionable proposition. [/QUOTE]
