  1. Vast ‘Structures’ In #Space Reveal the Universe Isn't What We Thought
    #Physicists discovered that #darkmatter structures that scaffold universe—known as “cosmic web”
    There is variation in distribution of matter on small scales, such as millions of light years, these distinctions should smooth out into a uniform pattern on the scale of #cosmicweb, network of large-scale structures made of dark matter, gas, and galaxies that stretches across universe

  2. Running, a pet, and an over engineered monitoring system.

    What’s not to like?

    (I am completely unsurprised that it was a physicist who found he really needed to measure what his pet was doing all night.)

    *‘Mollie has become something of a star in the running world after de Buck, a Dutch physicist, rigged a system to track the critter's movements on the running app Strava.*

    *"I trained for a marathon for like half a year and gave a good effort, I thought. I got, like, maybe 40 'kudos,' which is like the 'likes' on Strava. But Mollie's getting about a thousand for each run each night," de Buck told As It Happens guest host Rebecca Zandbergen. "It's not fair."’*

  3. To understand #blackholes, #physicists turn to a mathematical ‘Rosetta stone’
    A link between particle #physics and #gravity applies to #HawkingRadiation
    Black holes aren’t entirely black. They emit mist of particles called Hawking radiation. But Hawking radiation is so faint it’s not possible to observe directly.
    Several teams are taking advantage of mathematical connection between two seemingly distinct types of physics — link known as double copy

  4. RE: mastodon.cloud/@slashdot/11681

    those 350 engineers should join line workers and unionize with the United Auto Workers #UAW

    like #baseball players and #Hollywood actors, #engineers #architects #physicists #scientists are the working class and deserve to be represented and defended by a #labor union

  5. We still don't have a more precise value for "#BigG"
    #Gravitationalconstant, affectionally known as “Big G,” is one of the most fundamental constants of our universe. Its value describes the strength of the gravitational force acting on two masses separated by a given distance—or if you want to be relativistic about it, the amount a given mass curves space-time. #Physicists have a solid ballpark figure for the value of Big G, but values vary by roughly one part in 10,000.

  6. #Physicists think they’ve solved the #muon mystery
    Results dash hopes for a fifth force but provide very precise proof of the #StandardModel of #particlephysics and quantum field theory. According to a paper published in the journal Nature, the discrepancy is due to a calculation fluke, not exciting new #physics, so the Standard Model of particle physics is still holding strong.

  7. #Physicists think they've resolved the #proton size puzzle
    There has been considerable debate among physicists over the last 15 years about conflicting measurements of the charge radius of a hydrogen atom’s proton—some confirming the predictions of our strongest theoretical models, others suggesting it was smaller than expected. The evidence has tilted in favor of a smaller proton radius and against new #physics.

  8. #Physicists find evidence that the universe isn't perfectly uniform — potentially unraveling a 100-year-old model of #cosmology
    The universe may not be perfectly uniform after all. The analyses revealed mild-but-intriguing deviations from the predictions of the #standardmodel. "We saw a surprising violation of an FLRW curvature consistency test, hinting at new #physics beyond the standard model," study co-author Asta Heinesen reports.

  9. 🔬✨ Ah, the noble #physicists, dusting off relics of the '90s to play clockmaker, like hipsters with a #time #machine. Meanwhile, their website performs a stunning magic trick: turning every curious click into a "400 #Bad Request" 🙃—an avant-garde #digital installation, perhaps? 🖥️🚫

  10. Hey #physicists. Could there be a kind of quark matter (maybe with top quarks) that was so dense a lump of it could fit inside its own Schwartzschild radius?

    If so, from outside the event horizon, how would that even in principle be distinguishable from a black hole with a singularity inside?

  11. How Plausible Is ‘#ProjectHailMary’? #Astrophysicists Have Thoughts
    Based on hard #sciencefiction, a genre that prioritizes scientific accuracy, the blockbuster gets a lot right but misses a few things, experts say.
    Armchair #physicists and even some actual physicists have powered countless online threads with questions around interstellar travel, alien life and why Grace, who has a doctorate in microbiology, can’t seem to balance a centrifuge.

  12. #physicists #engineers, #electricians and #roofers

    I've got a wooden house. A new roof has gone on. After the removing of solar hotwater pipes, there is no longer any path to ground from the corrugated steel roof.
    (How do I know? One of the screws cut into a cable and electrified the whole thing. No RCD tripped. Golly.)

    Would you strap it to earth? To a sacrificial anode? Neither? What reasoning please? We live on top of a hill and have lovely thunderstorms.

  13. #Physicists dream up ‘spacetime #quasicrystals’ that could underpin universe
    Orderly structures that never repeat can exist in melded space and time of Einstein’s relativity
    Instead of existing in two or three spatial dimensions, these quasicrystals’ structures would bridge space and time. Although theoretical, the researchers suggest that such spacetime quasicrystals may appear in nature, perhaps even underlying the structure of the universe.

  14. 1/n Notes on #UAP Discussions : This particular exploration is a milestone. If we map what they eventually wind up talking about to vexing questions in current #Physics we have a direct confrontation with #GeneralRelativity, #QuantumMechanics, and the applied mass- energy firewall problem that lies at at the heart of several open problems in #Cosmology and the SM. It should be noted that the intuition of #Engineers in this case is capable of beating #Physicists to the punch.
    There is a bit…

  15. #Fusion #Physicists Found a Way Around a Long-Standing Density Limit
    For a long time, the #GreenwaldLimit was accepted as a given and incorporated into fusion reactor engineering. The new work shows that precise control over how the #plasma is created and interacts with the reactor walls can push it beyond this limit into what physicists call a 'density-free' regime.
