EdEarl Posted February 21, 2016 Posted February 21, 2016 A photon travels a Planck length (lP) in a Planck time (tP). If the wavelength of the photon is lP/2, then two wave fronts would pass across lP in one tP. That seems like moving information (2 wave fronts) faster than the speed of light. Perhaps one must make a distinction between carrier and modulated waves; although, how one might modulate a single photon is beyond me; meaning the two wave fronts are only one bit of information. I haven't seen this idea discussed; thus, this my thought must be bogus. Why?
imatfaal Posted February 21, 2016 Posted February 21, 2016 That logic works just as well (ie I think not at all) for all wavelengths. If the wavelength is 1 cm and the gap is 30cm - that is 30 peaks and troughs per second. But to send any information - even if you could modulate the rising part of the 1st trough the "changed bit - the message" would still take about a nanosecond to get from transmitter to receiver
swansont Posted February 21, 2016 Posted February 21, 2016 How is it that two wave fronts comprise information?
EdEarl Posted February 22, 2016 Author Posted February 22, 2016 Sometimes I just need a reality check. My reading takes me to many places. Is the Universe a hologram or the computer simulation of a god.
