Embarking on a digital quest through the vast citadels of Google and beyond, an ancient relic was unearthed: the revered "export" scroll dated September 5, 2014. Rejoice, for the chronicles thought lost have been found. Welcome back to the complete tapestry of TTI.
I could buy that... or maybe a wave of sheer momentum, which can have mass, or may not need mass (photons)? I'd be interested in discussing the possibilities of this more with you.Perhaps a gravity wave...
Excellent. And yes, it can be heard AND felt, since hearing is just a higher-resolution mechanical sense to feeling. Both involve pressure waves. But in the case of the ear, the frequency response of the receptor (and therefore its discriminative capacity) is much higher than the frequency response of the skin's mechanical receptors.when speed of sound is broken, the "ether", in this case the atmosphere, is compressed. This can be heard, or more correctly felt, not only by our ears but our whole body if close enough. The very fabric of the frame of reference is distorted.
Right on! We have mastered supersonic and hypersonic flight by understanding the best shapes to make use of the medium. Dynamic pressures (the power-square law) are what generate the forces required to maneuver the vehicle. We must now do the exact same thing with the superfluid medium of background Space, and the speed of light as its defining "barrier" for phase transition.The energy required to break the sound barrier is much greater for less aerodynamic designs (and more violent a process), so breaking the light barrier would be much easier if it was understood how to minimise friction generated when hitting the virtual particles in space.
Yes. The concept of "external momentum" of a body is exhibited by translational and rotational velocities (motion). We typically measure the "internal momentum" of a body by temperature, which is actually described as the average molecular velocity of the matter comprising that body. But I maintain there is another important measure of "internal momentum", and that is the natural (resonant) vibrational frequency of the body. Different bodies resonate at different frequencies. Therefore, if one wishes to modify "internal momentum" to achieve an imbalance with the body's external momentum, you ought to be able to do this by tweaking both the temperature and the resonant frequency of the body.Momentum may exist where-ever there is motion. The momentum of a body at rest (inertia) is simply momentum whose sum equals zero (the vibration of a particle at rest has an equal backwards and forwards momentum component (as the particle vibrates back and forth)which cancels eachother out.
Not even a problem! One reason I got the nickname Rainman is because I have a habit of repeating scientific facts to myself, as I am trying to solve an engineering problem! /ttiforum/images/graemlins/smile.gifSorry this is physics 101, I'm just thinking aloud.
Yes, they are! As I inferred above, the basics of orbital mechanics tell us that we have to accelerate a body to a given velocity in order for it to be able to escape from the gravity well of a planet. In this we are simply increasing the external momentum of the body.I have also made a big assumption that gravity and momentum are implicitly interwined somehow.
If so, this is where the analogy to aerodynamics and the speed of sound seems to fall apart. While aerodynamic forces do begin to reduce after Mach 1 (and eventually level off), the body is never completely free from the momentum effects of the fluid.Having left the gravity wave behind, the craft is no longer subject to external momentum affects! (gravity?)
The way time breaks down around a rotating cosmic string has given Mazur and Chapline a clue to resolving this issue. The CTCs form in regions close to the cosmic stringâ€™s axis, which means relativity breaks down in the cores of tiny "gravitational vortices" while continuing to apply everywhere else. "This is very suggestive of a vortex in a superfluid," says Mazur.
