So I’m reading an article in New Scientist about problems nailing down the #HubbleConstant and I thought, if the universe is expanding, as in adding new space where there already is some, why isn’t everything expanding with it? All I can think of is, it’s gravity doing it, keeping localized bits of matter together, from subatomic particles to galaxies in size, essentially fighting an epic, mythic battle against The Expansion. Which side are dark energy & dark matter on?

Do ongoing tensions leave room for new physics?
One century after Edwin Hubble revealed his astonishing discovery of a cosmos beyond the Milky Way, the most precise measurements still can’t agree on how fast galaxies are moving.

Turning the #Hubble tension into a crisis: New measurement confirms #universe is expanding too fast for current models
The universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of #physics.
They arrived at a value for the #HubbleConstant of 76.5 kilometers per second per megaparsec which matches existing measurements, but not as our current understanding of physics predicts it.
