A nonlinear study refers to an approach that does not follow a straight, sequential path in analyzing or modeling phenomena. Instead, it allows for complex relationships where changes in one variable do not directly correspond to changes in another, often leading to unpredictable outcomes. In the article, a Princeton scientist explored the nonlinear dynamics of boson stars, a type of black hole mimicker. His research revealed unique gravitational wave signals during mergers, distinct from those of traditional black holes, which could aid in identifying these mimickers in future gravitational wave observation
It’s impressive how much detail Juno was able to capture even on the night side. What I love about Io is how it’s instantly recognizable. Nothing even remotely resembles it in the solar system.
Evidence suggests that this feature is the projection of a shell on to the plane of the sky. Voids and string-like formations are common outcomes of large-scale structure. However, these structures have maximum sizes of 150 Mpc, which are an order of magnitude smaller than the observed GRB ring diameter. Evidence in support of the shell interpretation requires that temporal information of the transient GRBs be included in the analysis. This ring-shaped feature is large enough to contradict the CP. The physical mechanism responsible for causing it is unknown.
Weird reporting like this is “new” GRB ring out of Swift and Sloan SDSS data.
Sloan Great Wall, which is around 1.5 billion light-years in length
South Pole Wall, which stretches 1.4 billion light-years across.
Hercules-Corona Borealis Great Wall, which is about 10 billion light-years wide
Cue the flat-earthers who are going to jump on this while completely ignoring all other aspects including the gravity required to make this happen, and somehow claim this is scientific proof that they were right.
If I understood this correctly, they analyzed incredibly blurry images and concluded that there are clouds of gas around galaxies, then they extrapolated the found gas up to all or almost all galaxies and concluded that it can fulfill the calculated expectations.
What I understood is kind of the opposite–they already knew there were hidrogene clouds around galaxies but analyzed some almost imperceptibly blurry images and found they were bigger than currently thought. They're blurry because they were taken in some wavelength not observable until now that is scattered by the ionized gas.
Astronomers have generally thought that massive black holes at the centers of galaxies expel gas in jets of material only during their formative years, when the central black hole is gobbling up gas and stars and producing lots of radiation. This makes them stand out as what astronomers call active galactic nuclei (AGN), or quasars.
If, as the new study suggests, the ionized hydrogen halo around galaxies is more diffuse, but also more extensive, than thought, this implies that the central black holes may actually become active at other times in their lives.
I love how we keep finding more and more about the role that black holes play in our universe.
I’ve been studying the range of neutron stars for some time and I feel confident it won’t be too long until much of our evidence and observations will show that black holes, quasars, super massive black holes and the range of other black holes are very likely, more extreme neutron stars - if not quark-like stars or stellar quantum-like objects. For fun, I’ve been also been focusing on colloids, extreme condensates and their quantum/relativistic phases/states; very revealing interactions and emergent properties. Now if we could just better observe zero-point energy…
