High-precision measurement of the W boson mass with the CDF II detector - PubMed (nih.gov)

"A sample of approximately 4 million W boson candidates is used to obtain [a mass W bosun], the precision of which exceeds that of all previous measurements combined....This measurement is in significant tension with the standard model expectation."

Down goes Frazier?

I love science, both the knowledge and the process of science. This paper, published with nearly 400 authors and in Science, likely the world's most respected peer-reviewed scientific journal, presents surprising results on the mass of W bosuns that lie way outside the value predicted by the standard model of physics. As such, it puts that model—which has guided physics research and understanding for decades—on the ropes.

But, the process of science won't let anyone jump to conclusions, not even four hundred authors writing in this journal. Nope, in a way, this paper really just kicks the process into the next gear. Testing and the oh-so-important work to verify the results come next. And, with this sort of work, that will take years.

So, is Frazier down?

Maybe, but in science and boxing, that doesn't mean the fight is over. This paper probably represents an early knockdown of the standard model (it's not the first). It took six for Foreman to be declared the winner over Frazier. So, now we wait. In the meantime, enjoy knowing that a revolution in our understanding of physics may be underway.

That doesn't mean the parlor games can't start now, though. And surely they have. Has Frazier fallen? We'll know someday, because...science.

‘Impossible’ Particle Discovery Adds Key Piece to the Strong Force Puzzle | Quanta Magazine (quantamagazine.org)

"Polyakov’s analysis suggested that the four quarks banded together for a glorious 12 sextillionths of a second before an energy fluctuation conjured up two extra quarks and the group disintegrated into three mesons."

The contrast between the precision of "12 sextillitionths of a second" and the vagueness of "an energy fluctuation" that "conjures up two extra quarks" is somewhat hilarious. This is fascinating otherwise.

The Latest Wrinkle in Crumple Theory (nytimes.com)

Interesting article about a recent Nature Communications paper on the math and physics of paper crumpling. I'll never looks at wastepaper basketball the same way again.

Engineers Have Proposed The First Model For a Physically Possible Warp Drive (sciencealert.com)

Turns out we don't need to break the speed of light barrier to become an interstellar species. We just need enormously powerful gravitational fields, like those provided by planets, to bend space time inside a warp drive.

Thinking about riding a warp drive around a planet makes me think of the song #Spacegrass# by Clutch:

Lay low, watch the universe expand.
Skyway, permanent Saturday.
Oh, by the way, Saturn is my rotary.
