The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

phys.org - Analysis webb universe expansion hubble

But new measurements from the powerful James Webb Space Telescope seem to suggest that there may not be a conflict, also known as the "Hubble tension," after all.

...

One major approach involves studying the remnant light from the aftermath of the Big Bang, known as the cosmic microwave background. The current best estimate of the Hubble constant with this method, which is very precise, is 67.4 kilometers per second per megaparsec

...

In the past, measurements with this method [measure the expansion of galaxies in our local cosmic neighborhood directly, using stars whose brightnesses are known] returned a higher number for the Hubble constant—closer to 74 kilometers per second per megaparsec.

This difference is large enough that some scientists speculate that something significant might be missing from our standard model of the universe's evolution.
