Hubble data: Universe "weirdly" expanding faster than expected.

With any luck, those of us who bet the universe will asymptote to a non-zero positive temperature value at maximum entropy and no further work being possible will be able to cash in on our "what is the ultimate fate of the universe?" wager.
The universe is destined to being a diffuse particle cloud. Deal with it. I'm talking to you, "Big Crunch" enthusiasts.

According to NASA, the data provided by the Hubble Space Telescope shows that the rate of expansion has become much quicker in comparison to the expected rate. But NASA was not able to provide a concrete reason behind the discrepancy and went on to call it “something weird”.
“You are getting the most precise measure of the expansion rate for the universe from the gold standard of telescopes and cosmic mile markers,” said Adam Riess of the Space Telescope Science Institute (STScI) and the Johns Hopkins University in Baltimore, Maryland, in a statement.
quote:
Riess is currently leading a team of scientists who have published a paper regarding the data collected from the Hubble Space Telescope and it was seen that other galaxies are moving away quite fast from ours – showing a clear increase in the rate at which the universe is expanding.
The Hubble telescope has been gathering data for the last 30 years and it shows that although it was predicted that the rate of expansion will be 67.5 kilometers per second per megaparsec with a margin of error of 0.5, the current rate of expansion is somewhere around 73.

Not necessarily. Earth isn't expanding. The solar system isn't expanding. The Milky Way isn't expanding. On the other end, atoms aren't expanding.
Intergalactic space is different from space affected by gravitational wells.

In other words...
"We still have no idea what the frick actually happens in the universe."

A pithy summary from Wikipedia,
quote:
Another universe could possibly be created by random quantum fluctuations or quantum tunnelling in roughly 10^10^10^56 years.[18] It is suggested that, over vast periods of time, a spontaneous entropy decrease would eventually occur via the Poincaré recurrence theorem,[19] thermal fluctuations,[20][21][22] and fluctuation theorem.[23][24] Such a scenario, however, has been described as "highly speculative, probably wrong, [and] completely untestable".[25] Sean M. Carroll, originally an advocate of this idea, no longer supports it.[26][27]

I’m coming up with thirty-two point three three uh, repeating of course, percentage, of survival.

If the cosmological constant in the Einstein Field Equations is sufficiently large, the expansion could eventually overcome the gravity and the strong/weak nuclear forces...literally tearing matter apart.

I think this is literally them realizing what they had calculated before was wrong, and calling it “weird” to save face

Dude, we got a baby formula shortage! Ain’t nobody got time for this!

They couldn't wait for james webb to send some pics back before publishing this?

I calculate 3^50 years.

Im pretty high right now and I thought this would be a cool thread to read, but you people are going to make my head explode with this shite.

Isn't our understanding of gravity that it is a curve in space itself? How do you know how gravity will behave as space continues to expand? What happens when the space inside an atom today becomes as large as the milky way? Will matter "work"? Does this even make sense?

they should just give up on the whole “expanding universe” nonsense. Cosmic bodies might be moving but the what do they think the universe is expanding into?
