Comment on James Webb Telescope Confirms That the Universe Is Expanding at Different Speeds

Comments

Interesting, could a physical system exploit differences in the rate of expansion?

What happens to an object as it moves from a high rate-of-expansion region to a low rate-of-expansion region?

the current thought is that these are measurement errors not actual differences in expansion rate but even if they were actual different expansion rates, they are separated by time not space.
