As a follow on to my previous post, surprisingly strong energy outbursts are consistent with what would be expected if a dimension with the same attributes as the other three is added to Minkowski space. Consistent with the thinking of how quasicrystals formed in red trinitite 50 meters from ground zero at the Trinity nuclear test, 3D space may be opening up into 4D space. This expansion is normal to 3D space. Phenomena we know is generally restricted to 3D space, however tunneling occurs normal to the path of light. Assuming gravity tunnels, more gravity would exist in 4D space. As time is a function of gravity time runs slower in 4D space. Equalizing events discharges energy. This should be in play from the size of the Universe to the Planck scale. The illusion of dark energy may be how 3D space opens up into 4D space. The should be fairly easy to mathematically validate by a mathematician with the right chops.

Recently, they made a breakthrough discovery while investigating these irregularities.   2. New Insights into Stellar Evolution:  The findings shed light on the complex processes occurring within Betelgeuse as it nears the end of its life cycle. This dying supergiant star has been closely studied for its potential to go supernova, offering a unique opportunity to understand the final stages of massive star evolution.   3. Spectral Analysis Reveals Surprising Data: Through detailed spectroscopic analysis, astronomers have uncovered intriguing details about the composition and behavior of Betelgeuse's outer layers. These revelations challenge existing models of stellar dynamics and may necessitate revisions to our understanding of stellar evolution.   4. Implications for Galactic Dynamics: The discovery has broader implications for our understanding of the dynamics of the Milky Way galaxy. Betelgeuse's evolution and potential demise could have significant consequences for nearby celestial bodies and the overall structure of our galactic neighborhood.   5. Future Observational Campaigns:  Armed with this newfound knowledge, astronomers are planning further observational campaigns to monitor Betelgeuse's behavior and unravel more mysteries surrounding this enigmatic star. These efforts could provide crucial insights into the fate of massive stars and the cosmic processes shaping our universe.

Here is some information about black holes ¹ ² ³: - A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. - The Milky Way could contain over 100 million black holes, though detecting these is very difficult. - At the heart of the Milky Way lies a supermassive black hole, Sagittarius A*. The colossal structure is about 4 million times the mass of the sun and lies approximately 26,000 light-years away from Earth. - The first image of a black hole was captured in 2019 by the Event Horizon Telescope (EHT) collaboration. The striking photo of the black hole at the center of the M87 galaxy 55 million light-years from Earth thrilled scientists around the world. - Black holes are expected to form via two distinct channels. According to the first pathway, they are stellar corpses, so they form when massive stars die. - Black holes do not die per se, but they are theoretically predicted to eventually slowly evaporate over extremely long time scales. - Black holes grow by the accretion of matter nearby that is pulled in by their immense gravity. - Hawking predicted that black holes could also radiate away energy and shrink very slowly. - Quantum theory suggests that there exist virtual particles popping in and out of existence all the time. When this happens, a particle and its companion anti-particle appear. However, they can also recombine and disappear again. When this process occurs near the event horizon of a black hole, strange things can happen. Instead of the particle antiparticle pair existing for a moment and then annihilating each other, one of them can get by gravity and fall into the black hole, while the other particle can fly off into space. Over very long timescales, the theory states that this trickle of escaping particles will cause the black hole to slowly evaporate.

The New Model applied to various astrophysical and quantum physical phenomena using rigorous mathematical derivations and analyses with focus on the mathematical structure and predictive power of The New Model. Model's equation is: Ui(a)=∑a−i∈AN(μ,σ2)[P(Ii∣a−i)P(a−i)P(Ii)(ui(a,a−i)+εi(a,a−i))+λSi(a)] Astrophysics: Galaxy Rotation Curves In this context: Ui(v) represents the expected velocity of a star i at a radial distance r from the galactic center. v−i represents the velocities of all other matter (visible and dark) in the galaxy. N(μ,σ2) represents the distribution of velocities due to inherent uncertainties. The Newtonian velocity prediction for a star in a circular orbit is: ui(r,v−i)=√GMvisible(r)r where G is the gravitational constant, and Mvisible(r) is the visible mass enclosed within radius r. However, observed rotation curves are flat, indicating: vobserved(r)≈constant≫√GMvisible(r)r for large r To account for this, we introduce: εi(r,v−i)=√GMdark(r)r+βvR2 where Mdark(r) is the dark matter mass within r, and the second term represents MOND (Modified Newtonian Dynamics) corrections with parameters β and R. λSi(r) represents tidal interactions: λSi(r)=∑jGMj(r−rj)3cosθ where Mj is the mass of neighboring galaxy j, rj its distance, and θ the angle between r and rj. Substituting: Ui(r)=∑v−i∈VN(μ,σ2)[P(Ii∣v−i)P(v−i)P(Ii)(√GMvisible(r)r+√GMdark(r)r+βrR2)+λ∑jGMj(r−rj)3cosθ] This formulation can better fit observed rotation curves by adjusting Mdark(r), β, and λ, offering a more accurate description than pure Newtonian or pure dark matter models.

With a new calibration technique, LOFAR can produce even sharper images at low frequencies.

Our own galaxy, the Milky Way, is home to anywhere from 100 to 400 billion stars, and at least as many planets. At the center of the galaxy is an intense radio source known as Sagittarius A*, a supermassive black hole that has incredible, incomprehensible mass and power. Scientists have revealed new imagery of the black hole looming at the center of the Milky Way. Seen through polarization, we see an incredible image that looks computer generated. But indeed, it’s the powerful magnetic fields spiraling outward from the center. Two new research papers document how these amazing images were captured, and give us a bit more of a glimpse into the awesome power of these astronomical forces. https://lnkd.in/eArG2XRk #SMBH #blackhole #astronomy

If you need a content creator, here's an example of content we produce: an #astronomy article about the discovery of a compact object within the globular cluster cataloged as NGC 1851 whose nature is uncertain because mass estimates place it on the border between a neutron star and a black hole. #SpaceMission #MeerKAT #NeutronStars #BlackHoles https://lnkd.in/di6ZNSGi
