I didn't understand this part of the article. We can measure the mass difference because, according to the theory, that is what we are measuring when we see a redshift. Should we not be able to measure the redshift in a laboratory, given equipment of high sensitivity and a large enough time delta for the change to register?
Edit: Looks like Le_SDT beat me to it :)
- Zikes 13y agoI would imagine so, that part confused me as well. It's possible that the level sensitivity required is just too extreme, and would be subject to too much local interference. There's one such test [1] that I find interesting that suffers from similar problems. It tries to detect gravitational waves traveling through the universe by pointing a laser at a mirror at the end of a 4km tunnel and measuring any changes in the total distance.
