The universe is expanding faster than it should

A new study has highlighted the fact that there is still much we don't know about the expansion of the cosmos.
Back in 1929, Edwin Hubble - the man after which the Hubble Space Telescope is named - made a fundamental discovery by realizing that the universe is not static but is in fact constantly expanding.

Fast-forward 90 years and while modern science has come a long way towards calculating not only the speed of this expansion but also the rate at which it is accelerating, there remain discrepancies that continue to challenge what we think we know of the expansion process.

Perhaps the most perplexing of all is the discrepancy between the predicted and calculated rates of expansion. One of the most recent efforts to measure the rate of expansion found that it was 9% higher than it really ought to be based on prior predictions.

Now a new paper has put forward another such measurement - this time using extremely detailed observations made by the Hubble Space Telescope. As it turns out - the new figure seems to concur with the earlier finding that the expansion is 9% faster than it should be.

The likelihood of an error in these latest findings is a mere 1 in 100,000, meaning that new physics may be needed to explain the discrepancy.

"This is not just two experiments disagreeing," said study lead author Adam Riess.

"We are measuring something fundamentally different. One is a measurement of how fast the universe is expanding today, as we see it. The other is a prediction based on the physics of the early universe and on measurements of how fast it ought to be expanding."

"If these values don't agree, there becomes a very strong likelihood that we're missing something in the cosmological model that connects the two eras."

Sure. And maybe our universe is just a locker in a subway station in another universe. Harte

Saints be praised !* †thank you danydandan. † I always thought that must be the case...but it's good to hear you agree. †And Harte gave it a heart...so he must agree too, †:o)

I was going try give an example, but. All I could think of was this famous analogy to explain the expanding universe. Imagine the universe like a loaf of raisin bread dough. As the bread rises and expands, the raisins move farther away from each other, but they are still stuck in the dough. In the case of the universe, there may be raisins out there that we canít see any more because they have moved away so fast that their light has never reached Earth. Fortunately, gravity is in control of things at the local level and keeps our raisins together. Also NASA knows their **** too. https://map.gs... [More]

Well, I'm slow, † But appreciative. † :o) † †..if you asked 100 people on the street if the space in their†atoms was expanding...what would they say ? ††

So, space/time curve back on themselves....so, is a circle finite or infinite ? †Where is the beginning or end of a circle ? ...just a thought. †I like thoughts. :o)

Thanks a lot Harte, † I just read several pages from your link, had to stop for now because my head was getting sore from scratching it ! † I remember you showing me a MŲbius strip years ago in another somewhat similar thread... Interesting ,to†me, that it so closely resembles "our" ancient symbol for infinity! †(without†the obvious twist) Thanks to you too danydandan for the links...I read them.
