What if the theoretical concept of a Black Hole is just a divide-by-zero error in Newton’s Law of Universal Gravitation? Could this mathematical artifact be masking a deeper truth about the universe? Let’s rethink the foundations.
Gravity is the weakest of all the known forces of nature. It’s also infinite in range.
Go figure.

Purely coincidentally, I just started reading The End of Everything (Astrophysically Speaking), by Katie Mack, known elsewhere as @AstroKate. She talks about the 5 different scenarios currently deemed possible, if not likely, for how the universe and everything in it will end, by theoretical physicists. Our choices are: Big Crunch; Heat Death; Big Rip; Vacuum Decay (which could happen at any moment); and the Bounce. A “…surprisingly upbeat ride…”. #bookstodon #theoreticalPhysics #science
(Re) Introducing myself after moving from emacs.ch: I am an academic interested in #math and #theoreticalphysics
I am at this instance because I contribute to some #Emacs projects (details to come in a follow up) and I am posting this using mastodon.el the Emacs client for fediverse.
Other than that I am interested in #fiction and #urdu #poetry. I am here to mostly read rather than write and it has shame that there is not much Urdu content here (I hope I am just missing some niche).
Welcome, welcome, welcome!
It's great to see that you're here! I'm a fan. I love ALL your writing and shows.
I wish you to have a great time, here.

if the universe is indeed infinite then there’s an alternate world out there where one of the bonus tracks on Taylor’s new album is a cover of “A Mouthful of Sores” from Mr. Show
But, when scientists attempt to use these theories to describe what happens in the interior of a #BlackHole, the implications are, as another astrophysicist put it, “a disaster.” Or, as Broderick put it, the theories “give very different answers.”
By Rivka Galchen
To look “into” a #BlackHole—from which no photon or wave or ray ever returns—requires considerable #creativity. The interior of a black hole can only be deduced from changes exterior to it. Active #BlackHoles are encircled by intense brightness & billion-degree heat, given off by matter falling toward them—think of the fire of an incoming asteroid—while the black hole itself is unthinkably cold, a tiny fraction of a degree above absolute zero.
Imagine the mass of Earth condensed to the volume of a marble; imagine a million suns condensed to the volume of a single sun—that’ll give you an idea of a #BlackHole. Some #BlackHoles are formed by stars that have collapsed in on themselves. Other black holes are thought to have been formed by the inward collapse of enormous clouds of gas. (There are other theories, too.)
As he explained it, a #BlackHole has a mass, an electrical charge, & an angular momentum (meaning it can spin). “And that’s pretty much it,” he said. “Their behavior is extreme, but the apparatus is something we think we understand.” Another “simple” way to think of a black hole is as an extraordinary amt of mass in a relatively small space. It exerts a gravitational pull so strong that not even light can escape it.
To me, a #SupermassiveBlackHole sounds sublime; to a #scientist, it can also be a test of wild hypotheses. “#Astrophysics is an exercise in incredible experiments not runnable on Earth,” Avery Broderick, a theoretical physicist at uWaterloo & at the Perimeter Inst, told me. “And #BlackHoles are an ideal laboratory.”
Broderick says that he studies black holes because they are very simple, theoretically & mathematically.
In Jan, #astronomers announced that the #JamesWebbSpaceTelescope had observed the oldest black hole yet—one present when the universe was a mere 400M yrs old.…Recently, 2 #SupermassiveBlackHoles, w/a combined mass of 28B suns, were measured & shown to have been rotating tightly around each other, but not colliding, for the past 3B years. And those are just the examples that are easiest for the public to make some sense of.
#BlackHoles Are Even Weirder Than You Imagined
It’s now thought that they could illuminate fundamental questions in #physics, settle questions about #Einstein’s theories, & even help explain the #universe.
…In recent yrs, the amt of data that scientists have discovered about black holes has grown exponentially.

We've had relativity, the physics of time, genius, the speed of light, the Grand Unified Theory, photons, black holes, quantum physics - but this is the first time Melvyn Bragg and his experts have considered Albert Einstein himself.
About time, you might say.
In Our Time, on BBC Sounds.
Of the four fundamental forces in nature only three – the electromagnetic force and the strong and weak nuclear forces – are explained by the #StandardModel of #ParticlePhysics.
The model can't explain the fourth fundamental force, #gravity, or #DarkMatter – a strange and mysterious substance thought to make up about 27% of the universe.
