Not bloody likely. All of the so called ``warp-drive'' proposals considered in literature require the existence of ``Negative'' matter (not antimatter) with negative mass, negative energy and negative gravitational attraction. Considering that this would violate both the second law of thermodynamics and the law of cause and effect, the existence of negative mass is therefore about as massively improbable as anything can get.
Well if you get limits of the time dilation formula, at the speed of light things should stop. So you wouldnt be able to stop since relative to everything else in the universe you arent moving at all.
"We see then that, just as happens with wormholes, one needs exotic matter to travel faster then the speed of light. However, even if one believes that exotic matter is forbidden classically, it is well known that quantum field theory permits the existence of regions with negative energy densities in some special circumstances (as, for example, in the Casimir effect). The need for exotic matter therefore doesn't necessarily eliminate the possibility of using a spacetime distortion, like the one described above, for hyper-fast interstellar travel."- The warp drive: hyper-fast travel within general relativity, Alcubierre (1994).
don't know... but Mr E albert will tell you that 300,000 kilometres per second... it's not just a good idea, it's the law.
As you speed by Earth at some arbritary fraction of light speed, you will observe an Earthbound clock to run slow and contract in length in the direction of motion. The mass of objects appears the same regardless of your velocity.
Recall that 4-acceleration is the proper time derivative of 4-velocity A<sup>u</sup> = dU<sup>u</sup>/dt<sub>0</sub> where 4-velocity is the derivative of 4-position with respect to proper time, and 4-position is a 4-dimensional vector in space-time of the form x<sup>u</sup> = (ct, x, y, z) where c is the speed of light, t is the time coordinate and x, y, z are the three spacial coordinates. Therefore U<sup>u</sup> = d/dt<sub>0</sub> (ct, x, y, z) = (c dt/dt<sub>0</sub>, dx/dt<sub>0</sub>, dy/dt<sub>0</sub>, dz/dt<sub>0</sub>). It's clear as day then that U<sup>u</sup> = gamma (c, v<sup>i</sup>) where v<sup>i</sup> = (dx/dt, dy/dt, dz/dt) is the ordinary 3-velocity. In the rest frame of the particle it is obvious that U<sup>0</sup> = (c, 0, 0, 0). Working through the algebra it can be shown that the magnitude of A<sup>0</sup> is equal to the proper acceleration alpha felt by the observer on the ship. Furthermore, the proper acceleration can be related to the coordinate acceleration a by
you're getting too nerdy?
He was talking about 4 dimensional velocity etc. Don't bother trying to imagine it, you wont be able to, humans can't. If you think 4 dimensions are hard try doing 11 or 12 (the amount theorised there to be).Originally posted by abdooooo!!!
zeropoint is nerd here... what the heck is that about? i should study more phy so i can communicate with the guy...
anyways here is a definition of 'quantum mechanics' that was deleted with the other thread: a crew kept on the payroll to repair quantums, which decay frequently to the ground state.
LOL. thats why didn't wanted to do cosmology... philososphy is much more logical. although you get crap like time travel in philosophy but that 11 or 12 dimensions m-brane theory is just totally queer.
you don't have to be faithful... thats the difference between philosophy and religion. and you don't have to believe in everything science tells you. its all intuition.
i don't know... i believe there is no purpose... how do you know its a bunch of electrical impulses anyway? it might be something more powerful... a force that is GOD.
Well since there is no time passing at that speed, there is no "just before", right?
Well you kindof can.
