Right, at that scale, For a galaxy to move a fraction of a centimeter will take a thousand years. So not much will be missed in a gap of 6 months.

- queuebert 2y agoThis is nonsensical. Do you mean a tiny movement in the field of view, which should be measured in angular distance? Or do you mean actual motion through the universe, in which case the galaxies are moving at hundreds of kms per second, which means they would move billions of kms in 6 mos.
- nashashmi 2y agoYes, field of view. I am considering 1 cm to mean 2-3 light years.
