Red shift shows that an object is moving away because the wavelength of the light is increasing. The wavelength DOES increase as it travels long distances. Red shift indicates that an object in space is moving away from you because the distance the light must travel to reach you is increasing, and this is apparent in the relative shift of the wavelength. So red shift actually has a lot to do with the distance traveled, but you're right in that you only talk about red and blue shift in terms to relative distance changes.After some thought, it makes a little more sense to me for the "slowing down" of the GDO signal to be due to time distortion.Since the light appears to be accelerating as it crosses gradients of time distortion, there would be an increase in time(distance) between the reception of each individual photon. This would result in an apparent "slowing down" of the entire signal, although in fact nothing would have actually been slowed down, just stretched. It would be kind of like if a bunch of people were running across five treadmills, each one continuous with the last, and all running at different speeds.   See 13 other replies

The idea of a black hole "slowing down" light is a matter of RELATIVE perspective. It is slowed form a perspective not within the gravity well.Light is only "red shifted" if the light source is moving away from an object, or as you said in a gravity well. The distance light travels is irrelevant to "red shifting".   See 13 other replies

Okay, a black hole cannot actually slow down light. A black hole's gravitational field creates a "well" that attracts matter and can appear to bend light, but it can't actually slow that light down. Now, what it might do instead of that is cause the light to have to pass through a much greater distance before entering the stargate. If that were true, the light would be attenuated, in the same way as light that travels very long distances to reach earth appears "red shifted." This is because of the Doppler effect.So when the light gets to the SGC's receivers, there is a possibility that the signal might be attenuated, or in other words degraded, to the point where the computer can't recognize the signal. What Sam ended up doing was just manually 'cleaning up' the signal so that it could be recognized.   See 13 other replies
