Imagination has much flexibility, empiricism does not. If a galaxy looks like an eddie now, but later it will evolve into a cluster, is it still an eddie. Or was it a cluster all along. Just trying to give the man the benefit of the doubt.

Its the only theory that takes in the entire cosmos. TreBert

Atoms don't behave anything like planetary > systems and irregular galaxies. - SW ---------------------------------------------------------- Sam, I can show you atoms that behave very much like planetary systems, in fact the atomic physicists who study them call them "PLANETARY ATOMS". Ever heard of them? They are atoms in highly excited Rydberg states. They involve particle- like electron wavefunctions, planarity, and orbiting just like the Solar System. Here is a direct quotation from a Physical Review paper: "We predict the existence of a self-sustained one-electron wave packet moving on a circular orbit in the helium atom. The wave packet is localized in space, but does not spread in time. This is a realization within quantum theory of a classical object that has been called a "Rutherford atom," a localized planetary electron on an unquantized circular orbit under the influence of a massive charged core." "[W]e provide the first demonstration of the existence of what has been called [14] a "Rutherford atom," i.e., the wave function for a single electron moving on an unquantized stable and nonspreading planetary orbit about a massive charged core." ----------------------------------- I can also show you atoms and stars displaying unique and rigorous discrete self-similarity, including masses, shapes, physical behavior and frequency spectra that match up amazingly well. See: http://arxiv.org/ftp/astro-ph/papers/0510/0510147.pdf The problem is that you are still thinking in terms of mid-20th century atoms. We have learned alot about atoms since then.

If you want scientists to seriously consider your ideas, then you must offer them some nice elegant retrodictions, and hopefully one or two definitive predictions. There are so many new ideas floated out every day from arxiv.org and the web that one needs a way to sift the wheat from the chaff. Science does this via retrodictions and predictions/testing. Saying the uinverse is a 143-dimensional hyper-vuvuzela is dandy, but if it can't be tested empirically what good is the idea? So I would encourage you to work towards a few good retrodictions and predictions for your ideas. RLO www.amherst.edu/~rloldershaw

Spacetime can run foreward,and backwards equally,and so it does. This is the heart of my 5th field force theory TreBert |
