#2This result has 8.3-sigma confidence, so it's as good as it can get statistically. Even greater confidence than that of the Hubble tension itself.
The Hubble Tension is real. The expansion of universe is accelerating.

They confirmed[0] that the Hubble Tension[1] is a valid discrepancy between the two different ways of measuring the expansion of the universe.

#4This does not seem strange to me, since time does not flow the same everywhere - and phenomena occur at different subjective speeds.

#6Can someone more familiar with the science help me out?
- On the one hand, the universe can be expanding at different rates.
- On the other hand, is it possible our approach to measuring the expansion (e.g., using Cepheid variable stars) might be the problem?

I don’t understand what “time does not flow the same everywhere” means. Can you elaborate?

#8Confused, are they saying that different parts of the universe are expanding at different rates? Or are they saying two methods give different results for the same parts?
Re: James Webb Telescope Confirms That the Universe Is Expanding at Different Speeds
#9Interesting, 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?

#10So it means it isn’t expanding like a sphere but like an irregular explosion?
