If true, would that mean that the observable universe is smaller than we thought? And that the distances to distant galaxies might be off as well?
- irjustin 7y agoWow great question, I'm just as confused. I imagine because the absolute distance is still the same, but how quickly it got to that position is what's unknown. The confusion I have is how much is redshift used to determine the distance of the galaxy vs using standard candle extrapolation?
- zahrc 7y agoFrom what I understand it’s size is the same as estimated before. Basically it just took less time, to reach its current size.
- thedaemon 7y agoIt's just relative.
