Likely it has already happened and we are still waiting for the light to arrive.

That's when I stopped and moved on to a different video.

Same here. I hate AI narration. Don't know why they just can't find a good orator to read the words. Most times I skip the video as it's too annoying to hear all the mis-spoken words.

I was going to say swamp gas; you stole my thunder.

Ty lol

It is not the size of the galaxy that they measure, but the redshift which they assume to be due to doppler recession. In fact, if that were true some of the galaxies must be receding from the Earth at 3 to 14 times the speed of light. The failure of the galaxies to obey the laws of physics is due to the application of the Big Bang or Expanding Universe idea that doppler recession is the cause of the redshift. Literally this means that redshift is due to something else intrinsic to the galaxy that causes redshift not doppler recession. Variations in both atomic and magnetic flux density have been shown to cause redshifts like this as well. Sound also redshifts or blueshifts at that source due to wavelength being a function of the air density surrounding the source of vibration in the air.

@@JoeDeglman Gravity on light is also happening during the transmission across time. Many things are happening at the same time that we may or may not realize. Great discussion in your post.

@@gibblespascack1418 cosmological observation defy the idea of 'tired light' redshift and show that redshift has nothing to do with traveling through space or other media. Light always maintains its frequency after being emitted by the source but does attenuate over time. Studies of frequency from GPS clocks also shows that, contrary to the General Theory, gravity or light traveling into or out of the Earth's gravity well, maintains it frequency instead and does not gravitationally red shift or blue shift. I.E gravity has no effect on frequency once the light is emitted by an atomic clock. AKA once emitted whether from cosmological sources or moving into or out of 'gravity wells,' light maintains its frequency. Redshift has also been shown to be a function of magnetic flux density at the source where the atomic clock is located. I.E. wavelength of the light emitted is a function of magnetic flux density or altitude. But once emitted, the frequency of the light never changes regardless of the medium or density of the medium it travels thorough, including vacuum space. Sound does a similar thing. Wavelength of the emitted sound increase when the air density decreases, which redshifts the frequency of sound, but once emitted the frequency does not change, but does attenuate. Certain things can block certain frequencies of light such as dust around a cosmological body or the walls of your house, but the frequency does not change if it comes through a different medium.

Redshift is not due to losing frequency passing through other medium in space or 'gravity' of an object it passes by. from Seeing Red "Tired Light Over the years, many people have argued that photons lose energy on their long voyage through space. This is an entirely reasonable idea, since the distances are the largest we have experience with. But there are several observational arguments that persuade me that this is not an important part of cosmic redshifts: The first is that as we look to lower galactic latitudes in our own galaxy, we see objects through an increasing density of gas and dust until they are almost totally obscured. No increase of redshift has ever been demonstrated for objects seen through this increased amount of material. Secondly, we have seen that if we look through extragalactic space, the example of quasars linked to low-redshift galaxies demonstrates that two objects at the same distance with closely the same path length can have vastly different redshifts. Finally, if we say there are clouds of a redshifting medium around each individual object, then there should be gradients of redshift across resolved objects, which are not observed. Further, we should see silhouetting and discontinuity effects between adjacent objects, which also are not observed. Perhaps on some level, light can get tired, but it does not appear to be significant in the redshifts we are dealing with."

@@gibblespascack1418 atomic clocks in GPS also show that frequency emitted by the clocks does not redshift or blueshift with altitude. AKA gravity has no effect on light frequency. Once emitted light maintains frequency. However, the wavelength of the light emitted is a function of magnetic flux density at the altitude where the clock is located. Since wavelength is a function of the density around the clock, redshift is a density function. But just like with sound where wavelength is a function of the air density at the source, which changes the wavelength and redshifts the frequency, light wavelength is also a function of magnetic flux density at the source which can redshift the frequency.
