Without an accurate sense of how much mass our galaxy encompasses, astronomers can't fully understand how it interacts with neighboring galaxies or how its internal structures form and evolve over time, among other important cosmological questions.
|
|
Physicists have one ready-made explanation for this behavior, but it is a cure that many of them think is worse than the disease: a fudge factor invented by Einstein in 1917 called the cosmological constant.
|
|
In 1999, two teams of astronomers discovered that the universe was expanding faster and faster with time, not slowing down, under the influence of some "dark energy" that appeared to behave exactly like Einstein's cosmological constant.
|

I feel like each table is populated by random objects, like an incense burner, a feather, a book, some dice, a bottle of prescription pills, a statue of a cat, it's super granular, like a cosmological question.
|
|
But this indirect method hinges on the assumption that models of the cosmos are correct, so if it gives a different answer than direct measurements of the neutrino mass, this might indicate that cosmological theories are wrong.
|
|
In 1999, he and Dr. Bousso set out to see if string theory could supply enough different possible universes to ensure a reasonable chance of one having a cosmological constant as small as what had been measured.
|
|
The variation in strength of the cosmological correlations as a function of the different shapes and sizes is called the "correlation function," and it encodes rich information about the particle dynamics during the birth of the universe.
|
|
The allure of such a cosmological treasure trove has motivated teams to build observatories to search for the neutral hydrogen signal in the Northern Cape of South Africa, the mountains of Tibet, and Antarctica, among other sites.
|
|
" In the framework proposed by the new paper the cosmological constant isn't so constant; Λ changes in accordance with the aforementioned tiny energy leaks as "a record of the energy-momentum nonconservation during the history of the Universe.
|

Following the botanical section is the astronomical section, with pictures of the sun, moon, and stars; and then the cosmological section, with pictures of circular geometric designs; and the zodiac section, which features emblems of the zodiac signs.
|
|
Space serves as the transcendental horizon of what is both incommensurable and terrifying about human life; cosmological time as a structure becomes a metaphor for our own desire to outlive the Earth and, with it, our own history.
|
|
" On the face of it, the two experts disagree: Tyson sounds confident that today's science is mostly right about the universe, whereas Greene, when asked to estimate that the chance our current cosmological models will survive, replies: "Tiny.
|
|
The work on counting universes arose from an effort to understand a fudge factor known as the cosmological constant, an antigravitational force associated with empty space that Einstein invented in 1917 to explain why the universe was stable.
|
|
We don't see anything preventing these processes from occurring at the moment (a strike against this hypothesis), but Sandberg says scientists should be on the lookout for unusual zones in which these natural cosmological process have been dramatically diminished.
|
|
And in "LOCK" by Auriea Harvey and Michaël Samyn of Tale of Tales in Belgium, you can zoom in and out of a riondala-like machine universe based on the cosmological belief of the Earth being at the center.
|

"You don't get a lot of chances to measure a cosmological parameter that shaped the evolution of the universe in the laboratory," Diana Parno, an assistant research professor at Carnegie Mellon University who works on the experiment, told Gizmodo.
|
|
Farnes' theory has its roots in a small note Einstein made to himself in 1918 while struggling to explain the cosmological constant—which Einstein first used to describe the dynamics of the universe—in his equations for general relativity.
|
|
At this end-stage of their brief life cycle (these systems only last a few hundred thousand years—a blink of the eye in cosmological terms), stars within Wolf-Rayet systems spin rapidly, producing stellar winds that move at horrendous speeds.
|
|
Instead, the researchers argue that the existence of dark energy is only necessary because current cosmological models ignore the structure of the universe and use theories based on approximations where matter is assumed to have a uniform density throughout the cosmos.
|
|
To learn more about the large-scale distribution of cosmological matter, a team of astronomers from the United States, Austria, and Germany analyzed data being churned out by the Illustris project—the most accurate supercomputer simulation of the universe ever developed.
|
|
Just like Pauli proposed neutrinos as a "desperate remedy" to explain why experiments seemed to be violating one of the most fundamental laws of nature, the existence of dark matter particles is inferred because cosmological observations just don't add up.
|

And, spookily, it behaves very much like a fudge factor known as the cosmological constant, a cosmic repulsive force that Einstein inserted in his equations a century ago thinking it would keep the universe from collapsing under its own weight.
|
|
"It was clear from the early days of cosmological simulations that many of the baryons would be in a hot, diffuse form—not in galaxies," Ian McCarthy, an astrophysicist at Liverpool John Moores University, told Quanta, which first reported the discovery.
|
|
To find out the origin of ultrahigh-energy cosmic rays, Olinto and her colleagues need enough data to produce a map of where in the sky the particles come from—a map that can be compared with the locations of known cosmological objects.
|
|
A team led by Julien Wit, a postdoc at MIT's Department of Earth, Atmospheric and Planetary Sciences, says the planet isn't heavy enough, or close enough, to cause such a dramatic stellar pulsation on its own, creating something of a cosmological mystery.
|
|
If this possible solution does indeed dominate the wave function for minisuperspace, it becomes plausible to imagine that a far more detailed and exact version of the no-boundary wave function might serve as a viable cosmological model of the real universe.
|
|
Teasing out the cosmological triangles and other shapes—which have been named "non-Gaussianities" to contrast them with the Gaussian bell curve of randomly distributed pairs of structures—will require more precise observations of the cosmos than have been made to date.
|
|
Dr. Weinberg, who once referred to this discrepancy as "the bone in our throats," suggested in a paper in 1987 that the value of the cosmological constant was random and could be high or low depending on where you were in the cosmos.
|
|
He wrote about suburban alienation ("Subdivisions"), the cosmological significance of tidal pools ("Natural Science"), metaphorical struggles for equality between oaks and maples ("The Trees") and a futuristic dystopia in which fast cars are banned by something called "the motor law" ("Red Barchetta").

Results from BOSS, using the red-shifts of galaxies of two different ages (3.5bn years and 5.7bn years) and of quasars 23bn years old, so far suggest a rate of expansion in keeping, to within a percentage point or so, with the cosmological-constant hypothesis.

"Until now all the cosmological predictions and observations of distant spiral galaxies similar to the Milky Way indicate that this violent phase of merging between smaller structures was very frequent," said co-author Matteo Monelli, a researcher at the Instituto de Astrofísica de Canarias.
|
|
He insists that reincarnation is just an embedded doctrine in the ancient Pali culture—a metaphor like all the others we live with, a cosmological picture that works well, not unlike the metaphors of evolutionary fitness and cosmology that are embedded in our own culture.

"Ever since the discovery of the acceleration in the Universe's expansion, almost two decades ago, there has been a puzzlement about the strange value of the corresponding cosmological constant Λ , the simplest, and so far most successful, theoretical model that could account for the observed behavior," the authors note.
|
|
"These results are an important confirmation of our cosmological models, which predict that small dwarf galaxies in the universe should also be surrounded by a population of smaller fainter galaxy companions," said Laura Sales, study author and assistant professor of physics and astronomy, at the University of California, Riverside.
|
|
Like everyone else at the time, he thought the size of the cosmos was fixed, and the only way he could get the equations to work for a static universe was by introducing a mathematical fudge factor he dubbed the "cosmological constant," symbolized by the Greek letter lambda.
|
|
One of the most promising explanations is that Einstein was on the right track when he proposed a cosmological constant—except now, instead of keeping the universe static, it serves as a kind of counter force against gravity, driving the universe to expand at an ever-accelerating rate.
|
|
"Ritual sacrifice is, among other things, an instrument through which humans have often believed it possible to directly engage and exchange with cosmological powers and entities in order to reinforce favorable stability—an annual harvest, for example—or effect desirable change—such as stopping the floods," Sugiyama told Gizmodo.

James Peebles of Princeton University was awarded the prize for cosmological discoveries, and Michel Mayor and Didier Queloz of Switzerland's University of Geneva were honored for the 210 discovery of the planet 51 Pegasi b, according to the announcement from the Royal Swedish Academy of Sciences in Stockholm.
|
|
If they can locate FRB beacons sitting at different cosmological distances, then according to Bing Zhang, an astrophysicist at the University of Nevada, Las Vegas, it should be possible to measure the amount of matter spread out in the vast emptiness of space between us and the sources of the flashes.
|
|
What the authors behind the current study suggest is that maybe the cosmological principle is bunk, and, if this is the case, then observations of distant supernovae take on a different meaning because we can no longer assume that the universe looks about the same for every observer in every location.
|
|
One of Morgan's remarkable achievements in this novel is to wind all the clocks at once: a mortal one, which stops too soon ("time is a horse you never have to whip"); a historical one, which stops when memory runs down; and a cosmological one, which never stops at all.
|
|
But "Part 8" of Twin Peaks: The Return proved not so easily digestible — surging with wordless, experimental imagery, intimations of cosmological enigmas, and a disturbing boldness, the then newest entry into David Lynch and Mark Frost's beloved series was immediately hailed for raising — or least deranging — TV's bar, the peakiest of all.
|
|
"The Hubble constant is the cosmological parameter that sets the absolute scale, size and age of the universe; it is one of the most direct ways we have of quantifying how the universe evolves," said Wendy Freedman, a study co-author and professor at the University of Chicago's department of astronomy and astrophysics.
|
|
And so cosmologists are off to the game that Lloyd Knox, an astrophysicist from the University of California, Davis, called "cosmological Whac-a-Mole" at the recent Chicago meeting: attempting to fix the model of the early universe, to make it expand a little faster without breaking what the model already does well.
|
|
We will never be able to see 'further' than this because the universe is expanding at a speed faster than the speed of light, so the light from objects beyond this cosmological horizon will never reach us and objects on the 'brink' of this horizon will eventually fade and disappear from our perspective.
|

I wanted to include this and other Nsibidi symbols then as an homage to this discovery, my Igbo heritage and ancestors and also to place LGBTQ Africans firmly within an African spiritual and cosmological framework as well, showing that we have never been "un-African" and definitely were not seen as such by our ancestors!
|

Creationists have tried to reconcile the bristlecones with a putative cosmological starting date of 4004 B.C. (Methuselah fits their chronology, but the older remnants have to be discarded.) The Long Now Foundation, a futuristic organization based in San Francisco, bought land in the area of Mount Washington, Nevada, in large part because it contained bristlecone pines.

In a derelict site that once housed the village's first grocery store, leading architectural photographer Yuri Palmin's newly commissioned series The Lower Site (2016) — which is how residents of the Special Astrophysical Observatory refer to their settlement — documents the coexistence and intimate relation between the physical reality of Soviet-era architecture, the imaginary of cosmological time, and everyday life in Nizhny Arkhyz.
|
|
A wide range of astrophysical and cosmological measurements have subsequently arrived at an intimidating composition of the cosmos: 5 percent atoms, 27 percent dark matter and 68 percent the even more mysterious dark energy that seems to be speeding up the expansion of the universe — all of which subverts any illusion that astronomers might actually know what is going on.

Wheeler illustrated the idea of spacetime foam using an analogy with the surface of the ocean, as retold by theoretical physicist Y. Jack Ng at the University of North Carolina, Chapel Hill, in an email: Professor Steven Carlip at University of California, Davis, published new research in September that builds on Wheeler's quantum foam theory to show that spacetime bubbles could "hide" the cosmological constant at a large scale.

From here we move rapidly back and forth between Egdod's world (for Egdod, the Land; for Sophia, Bitworld), and Sophia in her own world as she is locked in a power struggle with El. In Bitworld, the new souls take on humanoid bodies and create language and tools, while Egdod rules over them in a cosmological system that reads like a composite of Greek mythology, Norse mythology, and early Christianity.
