Our Universe is expanding faster than science can explain, sending physics into "crisis" mode

Observations suggest that galaxies are moving apart at a higher rate than scientists have long expected. Many now wonder if the standard model of cosmology can fully explain what’s going on.

Dan Scolnic is an associate professor of physics at Duke University. He and his team led a new study, published in the Astrophysical Journal Letters, that strengthens the case for a mismatch between data and predictions.

Century of tracking

Another daily physics crisis. Threatening to upset our understanding of the universe. Textbooks will have to be rewritten. DeGrasse says it’s all a simulation anyway. What me worry?
I would think the next convocation of physicists should have as its main topics, the following: What physical parameters are always true all the time? What physics models have no objections? Where, in time, does our ability to observe an event stop?
Is it true that the key to the past is the present?

What if things are still in the acceleration phase? How would we even know?

[SunkenCiv]

Yeah, 'crisis', good one. :^) Thanks martin_fierro. Graphic apropos as always!

Each time I hear the world’s top physicists change their minds about how fast the universe is expanding, or how much it’s curved, or where, when and how the Big Bang originated - whether there even was a big bang - I chuckle to myself and think - jeez.. these guys don’t know what the f they are talking about.

[Strict9]

I agree. Their ideas change every now and again. I found a chemistry book from a garage sale from the 1940’s and in it, they said a neutron was a collapsed electron or some such. It would tire of spinning around and slam into a proton, and then their charges would cancel out. That is what was taught in schools.

If only the scientists understood the gravity of the situation, they would redouble their efforts to solve this problem. E=mcc2

The answer has been known for years......42

[aimhigh]

I read once from an astronomer that there was a theory that the speed of light has slowed down since the formation of the universe.

My first thought also.

Sheldon?

I guess we have to go beyond “dark matter” and invent “mysterious matter”

[Bratch]

[A_perfect_lady]

How can the universe have any boundary at all, let alone an expanding one?

I figure the black nothingness goes on forever, and the "edge" of the universe is just where you start seeing stars and matter and stuff. Like, imagine you're standing on a black surface that goes on in every direction for as far as the eye can see. Now imagine you throw a handful of salt on it. The universe is that handful of salt. Once you get beyond where the last few grains of salt are, there's nothing.

[Strict9]

yeah, the dark matter and dark energy nonsense is great for a disney movie but not so much in real life. What nonsense. We are literally one step from saying crow laid an egg in the river of life like the indians. We just make ours sound fancier (and some math)

[GOPJ]

Is this anothr one of those “problems” that will be solved if we give money to nutty liberal ‘elites’?

"Our Universe is expanding faster than science can explain"

I recall something from physics about the speed of light changing with the media it travels in.

[Nateman]

Ever notice how bright the light is on a microscope slide but how dark the object looks under the microscope? It is because you are only getting a small bit of that light in the magnified view. This is how I explain the expansion of the Universe issue. If you look at an object 13 billion light years away you are seeing it on a sphere 13 billion light years in radius. The Universe back then was probably smaller than that sphere . The result is dimming and magnification of the object. You could easily be fooled into thinking the rate of expansion of the universe is accelerated.
