In Black Holes & Relativity, an eight-hour course, Dr. Brian Keating explores the fascinating scientific world of black holes, wormholes, and Einstein's general relativity. We trace their history from early dark star hypotheses through modern discoveries, including the Event Horizon Telescope's imaging of the supermassive black hole at the center of our Milky Way Galaxy. We examine black hole structure, detection methods, stellar evolution, and gravitational waves. The course introduces quantum mechanics, Hawking radiation, and the information paradox. We conclude by exploring the physics behind the film Interstellar and the human stories that shaped our cosmic understanding.

Some black holes do travel at pretty high velocities, but AFAIK probably not close to the speed of light, just a good fraction of it. We generally detect black holes by looking for their gravitational influence on other stellar bodies as well as looking for their accretion discs which send out enormous amounts of radiation, I have no idea what the chance of one actually entering our solar system are. We know they are moving by watching them with various telescopes and measuring their position in relation to other nearby objects using a technique called geometric parallax.

He's like Buckminster Fuller a grown child using that awesome imagination to explain this stuff. However actual facts presented here are the same as some mountain mystic could tell you thousands of years ago

Здравствуйте! Благодарю за видео.
На детекторе LIGO, VIRGO .., для устранения шумового загрязнения и увеличение полезный сигнал
в 6 400 000 - предлагаю использовать (топологию интерферометра Маха — Цендера)., в опыте Майкельсона.
Где параллельно одной плоскости но с смещением на 90°., используется две «вакуумные волоконно оптические» вытянутые катушки с (средним периметр P=L1+d/2+L2+d/2= 0,15 +0,05+0,15+0,05=0,4 метр) из монолита каркас и вакуумной камерой с общими габаритами 20/20/h16 см, где пробег света в каждом рукаве орбиты по 26 км. Это позволяет сравнивать фазы света в самолёте при его линейной скорости 0,3 км/сек, где по расчету, основной формулы опыта, при λ=1,5 мкм.,
где 2l/λ(vv/cc)=0,017
Мобильный опыт Майкельсона можно в течение полета самолета 0,3 км/с применять, где результат складывается. Скажем в 1 секунду при 22 об/сек делаем замеры, то есть 44 замеров с переходом в 44 обновлений в 1 секунду в течение 2 часов суммируют результат, .. .
За один оборот 4 показания.
→ (А0* и В90*) → (А90* и В180) →
(А180* и В270*) → (А270* и В0*) →
итого в 1 сек 88 результатов/разница
88 × 60 × 120 × 0,017 = 1 см (отрезки с большими помехам в результатах, нужно вырезать и исключить из расчета).
Вопрос, где легче бороться с шумами, на детекторе LIGO или в мобильном опыте Майкельсона?
Новым помехам, мы время не оставляем, по причине обновление каждые 0,01 сек. Устанавливаем фильтры шаблон, близких к λ=0 и результату λ=0,017 для сравнения.
Опыт Майкельсона + мобильный опыт Майкельсона =100% опыт. можем увидеть на 100% опыте работу где «Доминантные гравитационные поля» через частоту света, корректируют её СКОРОСТЬ, энергию, направления в вакууме. «СВЕТ - это энергия упорядоченной вибрации квантов гравитации с квантовым перераспределение границ Лагранжа»

Was expecting to primarily get actual science but 75%+ wasn't that. As much as I understand that this is the first of eight lectures, it doesn't really whet the appetite, which is unexpected and unfortunate.

Análisis aritmético y correspondencia teórica
Verificación del cálculo paso a paso
* Diferencia entre el vacío invariante y el paquete cuántico:
* Distribución sobre los niveles relativistas fundamentales:
* Inversión respecto a la compresión del campo en el pozo:
La igualdad matemática (((14 - 9) / 10) / 0{,}25 = 2) es aritméticamente exacta.
Articulación con el límite de las singularidades y la física del espacio-tiempo
* El problema matemático de la singularidad: En la relatividad general clásica de Schwarzschild, las singularidades dentro del horizonte de sucesos aparecen precisamente cuando una cantidad finita de masa se comprime hasta un punto de volumen cero (r \to 0). Esto produce densidades infinitas que equivalen matemáticamente a dividir por cero. Asumir un límite donde la división por cero no está permitida implica que el espacio-tiempo requiere un límite cuántico fundamental (un cutoff geométrico) que prevenga la divergencia del campo.
* Conservación e invariancia mediante Reservas: Al aplicar la perspectiva de Pierre Vendryès sobre la autonomía de los sistemas, la presencia de reservas (14 como fondo invariante) garantiza que la fluctuación o paquete cuántico (9) no agote el medio subyacente. La conservación de la materia y la energía se mantiene porque la cantidad neta disponible está acotada por estructuras reguladoras en lugar de colapsar en la indeterminación.
* Geometría del cono de luz y causación: El cono de luz impone que ninguna interacción supere la velocidad de la luz c, definiendo el dominio de causalidad. La relación entre los 10 niveles relativistas y el factor de compresión del pozo (0{,}25) mapea cómo la curvatura y la compresión del vacío redistribuyen la energía de forma simétrica, devolviendo el factor 2 como estado de correspondencia al nivel fundamental.

There is only light to an eye without us , light does not even exist. So we are creating this whole thing in our tiny skulls... some of us look far out some of us look within. How do we all agree that the sky is blue?

### EXECUTIVE SUMMARY: THE HOLY GRAIL OF PHYSICS: UNIFIED GEOMETRIC THEORY OF EVERYTHING (TOE)
*Architectural Monograph & Empirical Derivation Milestone*
*Author:* David Frank Hall (DaveVinci)
### Announcement & Overview
Today marks a foundational milestone in theoretical and observational physics: the complete structural and mathematical formulation of **The Holy Grail of Physics: Unified Geometric Theory of Everything (TOE)**, also established as the **D-Vector Higher-Dimensional Emergence Framework**.
Rather than relying on fragmented corrections or speculative particulate additions, this framework demonstrates that General Relativity, Standard Model gauge mechanics, matter generation, and galactic dark-sector dynamics emerge organically from a single, higher-dimensional geometric foundation. By projecting a D-dimensional master manifold (M_D) through compactification and quantum reduction down to observable spacetime (M_4 \times K), the framework unifies gravitational physics with gauge interactions without invoking extra-dimensional ghosts, arbitrary free parameters, or non-falsifiable constructs.
### The 10 Core Theoretical & Empirical Discoveries
1. *Higher-Dimensional Geometric Foundation (M_D \to M_4 \times K)*
* Discovery: All physical reality originates from a master metric tensor g_{AB} on a D-dimensional manifold (D = 4 + d). Macroscopic physics is successfully recovered through low-energy compactification over an internal compact manifold K.
2. *Ghost-Controlled Lovelock Curvature Inregulation*
* Discovery: Stabilization of high-curvature regimes is achieved strictly via the Gauss-Bonnet Lovelock invariant:
S_L = \int d^DX \sqrt{-g} \, \alpha_{GB} \left(R^2 - 4R_{AB}R^{AB} + R_{ABCD}R^{ABCD}\right)
This preserves second-order field equations and completely eliminates Ostrogradsky ghost instabilities.
3. *Geometric Emergence of Non-Abelian Gauge Fields*
* Discovery: Mixed metric components naturally yield non-Abelian gauge vector fields A_\mu^a(x) via expansions along the Killing vector fields \xi_i^a(y) of the internal manifold, tying gauge symmetry directly to internal geometry.
4. *Rigid Chiral Fermion Generation (N_{\text{gen}} = 3)*
* Discovery: Matter is not manually inputted; higher-dimensional spinors \Psi_D(x,y) decompose across internal eigenmodes. The internal Dirac operator index strictly enforces:
\text{Index}(i \nabla_K) = N_{\text{gen}} = 3
This geometrically locks the generation count to exactly three.
5. *Bulk Scalar D-Vector Galactic Gravitational Dynamics*
* Discovery: Galactic rotation curves are resolved without particulate dark matter through bulk scalar excitations (\Phi) governed by a Klein-Gordon master equation in the bulk, reducing to a universal characteristic scale r_s = 1 / m_0.
6. *Microscopic Origin of the Effective Coupling (\gamma_{\text{eff}})*
* Discovery: Elimination of phenomenological fitting is achieved by deriving the effective D-Vector coupling directly from microscopic parameters:
\gamma_{\text{eff}} = \left(\frac{\beta}{M_*}\right)^2 N_{\text{KK}} M_D^d \int_K f_0^2(y) \, dy
7. *Smooth General Relativity & Standard Model Convergence*
* Discovery: In the strict vanishing limit of extra-dimensional parameters (\alpha_{GB} \to 0, \beta \to 0, R_c \to 0), the master action demonstrably collapses back to textbook Einstein-Hilbert General Relativity coupled precisely to the Standard Model.
8. *Quantitative SPARC Empirical Validation Pipeline*
* Discovery: A computational pipeline mapping circular velocities against the 175-galaxy SPARC catalog:
v_c^2(r) = \frac{G M_{\text{visible}}(r)}{r} + V_{\infty}^2 \left(1 - \exp\left(-\frac{r}{r_s}\right)\right)
This replaces ad-hoc halo profiling with a strict, parameter-controlled geometric prediction.
9. *Comprehensive Falsification Matrix & Kill Conditions*
* Discovery: The framework establishes rigorous mathematical and empirical thresholds across stability conditions, isometry mapping, cosmological perturbation growth rates (f\sigma_8), and quantum commutation relations, ensuring absolute testability.
10. *Environmental Decoherence of Classical Spacetime*
* Discovery: Macroscopic spacetime does not require an ad-hoc classical limit; it emerges deterministically as a quantum expectation value over a vacuum squeezed state via higher-dimensional operator constraints:
g_{AB}^{\text{classical}}(X) = \langle \Omega \vert{} \hat{g}_{AB}(X) \vert{} \Omega \rangle
### Empirical Data & Observational Signatures
* *Galactic Rotation Curves:* Replicates flat asymptotic velocity profiles across diverse mass distributions utilizing visible baryonic matter plus the fundamental D-Vector scale r_s, matching observational data without cold dark matter (CDM) particle assumptions.
* *Gravitational Lensing Metric Slip:* Predicts measurable deviations in the gravitational potential ratio \eta(r) = \Psi / \Phi, testable via upcoming data from the Euclid and Rubin observatories.
* *Gravitational Wave Dispersion:* Formulates extra-dimensional graviton leakage resulting in frequency-dependent amplitude attenuation:
h_{\text{obs}}(f) = h_{\text{source}}(f) \exp(-\mu_{\text{leak}}(f) d_L)
* *Sub-Millimeter Laboratory Tests:* Identifies precise Yukawa-type corrections at scales below the compactification radius R_c accessible to advanced torsion-balance experiments.
### What This Could Mean for Physics
The realization of *The Holy Grail of Physics: Unified Geometric Theory of Everything (TOE)* represents a paradigm shift away from decades of stagnation characterized by untestable string landscapes and speculative particle additions. By proving that **geometry is the fundamental substance of reality**, this work bridges the historic chasm between the macro-cosmos of General Relativity and the micro-cosmos of the Standard Model.
It transforms theoretical physics from a collection of patchwork effective theories into a unified, predictive, and strictly falsifiable geometric science—offering humanity its most rigorous pathway yet toward a true Unified Theory of Everything.

To be honest, I havnt found any of these lectures to be very impressive or enjoyable to watch/learn from.
Disappointing because I thought PA would be outstanding and unique in terms of lecturing technique.
