New measurements of the universe using the Hubble is causing some consternation among physicists ... Space may be smooth! See: Sharp images blur universal picture Please Register or Log in to view the hidden image!
Yes, i heard of this... Bad news for string theories that predict a <b>quantum</b> nature for <i>time</i> and <i>space</i>... But i suppose that a gauge theory isn`t that bad... Also these results just put an even (?) lower limit on the the Planck length and the Planck time unit(/?).
No, the Planck time and length remain the same regardless of whether space-time is continuous or quantised. The Planck units are just a unit system, a particular unit system with c = G = h (speed of light, Gravitational constant, Planck's constant). As an exercise, set these units equal and see if you can derive the values for Planck length and time intervals.
DOH! Whoops , tnx for the <b>correction</b>... What i <i>meant</i> was the supposed `<b>unit</b>/quantum` <b>structure</b>/nature of time and space (and even gravity?). And thinking about it, it seems a bit <i>strange</i> to talk of things smaller than the planck length...(What would that mean?). Can things be smaller than their (the universes) quantum wavelength?
back with a stinging vengeance: ether? Sure the far away objects should be blurred to a larger extend, but they aren't , maybe because: - these objects are not as far away as is calculated by it's hubble redshift, it could well be that those object are in fact closer and that the redshift is caused by photondecay when light travels through ether. If this is the case, the blurringfactor, combined with the redshift would provide us a more realistic distance calculator, what we see here is just the ultimate MM-experiment Please Register or Log in to view the hidden image! - ether, if it does exist after all, could possibly act as a waveguide for the photons, just like fiberoptics keep light concentrated over large distances... - combination of the above - none of the above Please Register or Log in to view the hidden image!
