Natural Science Forum / Physics / Relativity / April 2006Field and Photon
Hallo NG what do You think about this: a Photon is a Quantum of light. Light is swinging EM-field. Since light is travelling through empty space, the EM-field must "there", before the Photon arives. Or in other terms, EM-field is a property of space. Thomas Heger Dear Thomas Heger: > Hallo NG > > what do You think about this: > > a Photon is a Quantum of light. Light is swinging > EM-field. Were you able to keep up with the photon, you would see the EM field as unchanging. Notice how the faster you move wrt the source of the light, the lower the frequency? That is what redshift means... > Since light is travelling through empty space, No such thing as empty space. Space exists because of matter/energy, and space is always filled with at least photons. > the EM-field must "there", before the Photon arives. In quantum mechanics, any particle takes every possible path. So you can't point to any particular volume of space along the "light beam's path", and correctly say that detected photon number #67893451 passed 100% through said volume. Space and time are meaningless in the quantum realm. > Or in other terms, EM-field is a property of space. Lack of EM-field is also a property of space. E-field alone is a property of space. M-field alone is a property of space. Curvature is also a property of space. The strong and weak nuclear interactions are a property of space. Whatever binds the quarks together is a property of space (since such bindings result is a construct with "size"). Space and spacetime are illusions that the quantum realm produces from matter and energy as "seeds". Don't waste your effort in populating an illusion with further "features". We need to understand the reality behind the illusion. Space is now uninteresting. What is between space and quantum is the real frontier. David A. Smith > Dear Thomas Heger: > [quoted text clipped - 36 lines] > > David A. Smith Thanks a lot I had an idea: I want to join (small piece) of spacetime and Em-field to a system. This system I call "space" and look, if it works as harmonic oscillator. The Em-field is functioning as clock.

There is no such stuff as "spacetime", that isn't rooted in something smaller and more fundamental. Something that isn't infinitely differentiable. > The Em-field is functioning as clock. Invert this. The meter is defined by time and EM. Light is the "bulldozer" that creates space *from* time. David A. Smith > Dear Thomas Heger: > [quoted text clipped - 26 lines] > > David A. Smith Hallo David A. Smith my idea for a cosmological model goes like this: spacetime consists of events, has four dimensions of type lightyear. The topology is roughly a hypersphere. A small piece of space is called a system. It "moves" through spacetime in the way, that it expands spacetime on the outside. The laws of this expansations are given by the wavefunctions of the EM-field (the wavefunction provides a "clock".) This clock is local, it exists in any piece of space(-time), since space and EM-field are regarded as two aspects of the same thing. The surface of this hypersphere is called "now" and moving outside in the way that it creates events and the wavefunction devides these events in space and time. The surface has the topology of a curved hyperarea and has three dimensions of type lenght. Thomas Heger > Hallo NG > [quoted text clipped - 4 lines] > before the Photon arives. Or in other terms, EM-field is a property of > space. EM field is a property of the quantum "vacuum". Our space is a part of the quantum "vacuum". Here is part of the whole picture, Volovik says it like it is very well in his book "The Universe in a Helium Droplet" page 461 sect. 33 Conclusion; "According to the modern view the elementary particles (electrons, neutrinos, quarks, etc.) are excitations of some more fundamental medium called the quantum vacuum. This is the new ether of the 21st century. The electromagnetic and gravitational fields, as well as the fields transferring the weak and the strong interactions, all represent different types of collective motion of the quantum vacuum." Now, how do you make this scenario work so the quantum "vacuum" is a relativistic medium?

Something to observe I prefere to call a system. Anything you look at is a system, and it gets a system by the definition of the observer. If I look at a small portion of a static field, this is a system, independent from that space is otherwise empty or not. Basic methods of quantum physics are the uncertainty principle, the Planck-constant, the phathintegrals. They belong to the behavior of the fields and particles, but I see no reason to apply them to space. Thomas Heger |
