![]() Light Attenuation Redshift Frequency Introduction When redshift is properly understood, it can tell us how far light travels before it drops beneath the visible spectrum. This study explains the true nature of redshift and provides a formula for estimating the rate at which light attenuates over extreme distances. This is the fundamental cosmological error that creates the fatal flaw in these misconceived hypotheses: big bang theory, expansion theory, Hubble’s law, dark matter, and dark energy. Unfortunately, for over 100 years redshift has been misinterpreted as a Doppler effect. We observe this phenomenon as a redshift, the tendency of visible light to drop toward the red end of the spectrum. Absorption and re-emission processes are also not the same thing, that is the light disappearing from the universe followed by new light being created some, usually extremely imperceptibly, short time later - they are not a change of wavelength of light that is in flight.As light travels extreme distances through space, its frequency slowly diminishes (attenuates). But these are not redshift/blueshift because those terms refer specifically and exclusively to a physical change in the observed wavelength of light - which must be from one of the three sources above. quirks of the brain's normal operation, the imbibing of mind-altering drugs, pathologies, etc. But perception is a whole different animal that belongs to neuroscience, rather than physics and thus many other things can affect it, e.g. In all cases it is due to a change in the wavelength. Were the Universe undergoing a hypothetical contraction toward a Big Crunch singularity, a cosmological blue shift would be seen instead for the same reason - the contracting spacetime would cause the wavelengths to shrink. ![]() As the Universe expands, so too does the wavelength of photons which are embedded within the space-time (you can think of it as like scaling up a bitmap), and this causes them to acquire a red shift. The cosmological shift - this is due to the changing scale factor of the Universe. This is a red shift Likewise if a photon is falling down a well to an observer residing within it, the photon will pick up energy and its wavelength will shift. One can also think of it as being due to the gravitational time dilation - in particular if one imagines an antenna at the bottom of a deep gravitational well, a person standing outside will see the alternating current in the antenna reversing its direction of flow at a slower frequency, and thus the EM wave it is transmitting will have to be suitably reduced in frequency so as for the two to match as they must by the laws of electromagnetism. The fastest macroscopic 1 objects that people accelerate go a few tens of kilometers per second. ![]() The speed of light is 300,000 kilometers per second. The thing to note is that redshift from relative motion is proportional to the relative velocity divided by the speed of light. The short answer to the (original) title question of "Does redshifts/blueshifts occur on Earth?" is yes, of course it does. I know this is dodgy, but if you decide to answer, please cater for a layman with relevant information, because I get the feeling that mis-interpretation runs deep in our quest for truth as a race. ![]() At lower intensities, the red/green axis dominates.Ĭan these occurrences, namely Bezold–Brücke shift, also be coined as redshift/blueshift given that the waves emitted by the subject being observed are at varied lengths after absorption and reflection and understanding that the main light source being the sun, can be at variable distances emitting wavelengths (varied after modification by atmosphere) when in contrast to the subject being observed and the observer?Ĭan the term(s) "redshift/blueshift" be used to explain the various changing spectral phases of our "individually perceived" world at any given moment? As intensity increases, spectral colors shift more towards blue (if below 500 nm) or yellow (if above 500 nm). The Bezold–Brücke shift is a change in hue perception as intensity changes. If so, my puzzlement now falls upon the seeming similarities in other theories which are used on earth in regard to colour perception, light intensity and the composite structure of photographs. I gather the basis of the principle as being - an increase in wavelength = a shift to red in the spectrum where alternatively a decrease = a shift to blue (blueshift). I understand the premise of the Doppler effect being attributed to redshift as well as the effects of space expansion and gravitational influence on light when speaking of redshift in astrophysics. In physics (especially astrophysics), redshift happens when light seen coming from an object that is moving away is proportionally increased in wavelength, or shifted to the red end of the spectrum.
