Gravitational wave frequency depends on black hole mass and orbit. LIGO detects signals from 10 Hz to kHz, which is within the audible range, so black hole mergers can be 'heard' by converting data into sound, even though they're not actually sound waves

Black Hole Can Ring Like a Bell A Black Hole can vibrate after it is disturbed. Instead of settling instantly, its horizon releases gravitational waves in fading tones called quasinormal modes. This is commonly known as Ringdown. Each tone carries information about the black hole’s final mass and spin, which is why physicists call this Black-Hole Spectroscopy. In a way, when Spacetime strikes a Black Hole, the Black Hole answers with its own gravitational sound. #BlackHole #GeneralRelativity #GravitationalWaves #Spacetime #Einstein #Astrophysics #Physics #Mathematics #Cosmology

What happens if you fall into a black hole? NASA's Discover supercomputer created a visualization simulating an observer's approach to the event horizon of a supermassive black hole. Astrophysicists generated approximately 10 terabytes of data over five days, which would take over ten years on a conventional computer. The model depicts a black hole with a mass equivalent to 4.3 million solar masses, comparable to the central black hole in the Milky Way. The simulated black hole has an event horizon extending 25 million kilometers. The video demonstrates the approach to the black hole from a distance of 640 million kilometers to its complete collapse. You can see how the space around the black hole appears and is distorted, as well as the accretion disk and photon ring.

One of Stephen Hawking’s scientifically most influential works was confirmed last week by a strong gravitational wave signal. The signal was detected in January this year by the LIGO/Virgo/Karga collaboration that combines 4 gravitational wave interferometers in the USA, Italy, and Japan. The analysis revealed that the event was a merger of two black holes of roughly 30 solar masses each, and also that of the final black hole. Hawking’s prediction (known as the “black hole area theorem”) was that since the surface area of black holes (which is proportional to the square of the mass) determines their entropy, the total surface area can only increase in a merger. The new observation confirms this beautifully. (Animation: Deborah Ferguson, Derek Davis, Rob Coyne (URI)/University of Rhode Island )

What happens if a star gets too close to a black hole? The black hole can rip it apart -- but how? It's not the high gravitational attraction itself that's the problem -- it's the difference in gravitational pull across the star that creates the destruction. In the featured animated video illustrating this disintegration, you first see a star approaching the black hole. Increasing in orbital speed, the star's outer atmosphere is ripped away during closest approach. Much of the star's atmosphere disperses into deep space, but some continues to orbit the black hole and forms an accretion disk. The animation then takes you into the accretion disk while looking toward the black hole. Including the strange visual effects of gravitational lensing, you can even see the far side of the disk. Finally, you look along one of the jets being expelled along the spin axis. Theoretical models indicate that these jets not only expel energetic gas, but also create energetic neutrinos -- one of which may have been seen recently on Earth.

SOUND, FREQUENCIES, ENERGY AND VIRBRATION The divine essence within creation. "Alpha waves in the human brain are between 6 and 8 hertz. The wave frequency of the human cavity resonates between 6 and 8 hertz. All biological systems operate in the same frequency range. The human brain's alpha waves function in this range and the electrical resonance of the earth is between 6 and 8 hertz. Thus, our entire biological system - the brain and the earth itself - work on the same frequencies. If we can control that resonate system electronically, we can directly control the entire mental system of humankind." - Nikola Tesla

Einstein's Theory Confirmed: Star's Orbit Around Milky Way's Black Hole Using ESO's Very Large Telescope (VLT), astronomers have, for the first time, observed a star orbiting the supermassive black hole at the center of the Milky Way in a manner precisely predicted by Einstein's **general theory of relativity**. Instead of following a closed elliptical orbit, as described by **Newtonian gravity**, the star traces a path shaped like a **rosette**. This phenomenon, known as **Schwarzschild precession**, had never been measured before for a star near a supermassive black hole. A visual representation exaggerates the effect to help demonstrate this relativistic behavior. **What is Schwarzschild Precession?** This is a relativistic effect in which the orbit of an object in the gravitational field of another does not close upon itself, unlike the neat ellipses of Newtonian predictions. Instead, the orbit shifts or "precesses" within its plane, advancing in the direction of motion. This observation adds further evidence supporting Einstein’s groundbreaking theories and offers new insights into the behavior of stars in extreme gravitational environments.

Did you know it’s against “the rules” to even post a video humming inside this so called “antechamber?” Why wouldn’t they want people to hear the incredible acoustics that emanate from it? Could it be because we’re not supposed to know that this mini-chamber was an acoustical filter? As Christopher Dunn states in his book ‘The Giza Power Plant’ “After building the resonators and installing them inside the Grand Gallery, the ancient Egyptians would have wanted to focus a sound of specific frequency, that is, a pure or harmonic chord, into the King's Chamber. They would be assured of doing so if they installed an acoustic filter between the Grand Gallery and the King's Chamber. By installing baffles inside the Antechamber, sound waves traveling from the Grand Gallery through the passageway into the King's Chamber would be filtered as they passed through, allowing only a single frequency or harmonic of that frequency to enter the resonant chamber. Those sound waves with a wavelength that did not coincide with the dimensions between the baffles would be filtered out, thereby ensuring that no interference sound waves could enter the resonant King's Chamber to reduce the output of the system”

Seeing a woman's hair move from the music inside a car is a pretty striking demonstration of physics in action. When a sound system produces powerful low-frequency waves, it's not just your ears that notice, the vibrations can be strong enough to shake objects, rattle panels, and even make hair visibly move. What I find fascinating is that music is really energy traveling through the air. The louder and more powerful the sound waves, the greater their effect on the environment around them. Moments like this make it easy to see that sound isn't just something we hear. it's something we can sometimes physically feel.

In the Sanskrit tradition, this primal sound is called "Anahata Nada," the "Unstruck Sound." Literally, this means "the sound that is not made by two things striking together." Thus, sound that is not made of two things striking together is a sound with no physical qualities, the "sound" of energy, the sound of the universe itself. Joseph Campbell likens this unstruck vibration to the humming of an electrical transformer, or the—to our ears—unheard hummings of atoms and molecules. Ancient Vedic traditions teach that the audible sound which most resembles and evokes in us the unstruck sound is the vocal syllable OM. This ancient mantra is composed of four elements: a sequence of three vowels: A, U, and M, and the silence which begins and ends the sequence, the silence which surrounds it. It might be said that the ultimate aim of Yoga is to enter this third dreamless realm while awake. Yoga means "yoke" or "join." Through yoga we "join" our waking consciousness to its "source" in the world of pure, qualitiless unconsciousness Studies have shown that Om chanting can induce changes in brain wave activity, particularly in the alpha and theta frequency bands. Alpha waves are associated with relaxation and meditation, while theta waves are associated with deep relaxation and sleep. In Hindu texts (Mandukya Upanishads), AUM is regarded as the sound of the universe, from which everything originated. It represents the sound of Pranava and the vibration of the four states of the Supreme Being. BENEFITS Chanting "Aum" can reduce cortisol levels, a hormone released during stress. This can lead to a decrease in anxiety and stress Improved concentration Improved lung capacity Calming effect on the brain Better cardiovascular health improves blood circulation

What Would Happen if You Fell into a Black Hole? ✍️ Falling into a black hole is a journey into the extremes of physics, where the laws of nature as we know them are pushed to their limits. Here's what you might experience: Approaching the Event Horizon: As you draw near, the gravitational pull intensifies dramatically. The side of your body closer to the black hole experiences a stronger force than the side farther away, leading to a stretching effect commonly referred to as spaghettification. This term vividly describes how objects are stretched into long, thin shapes in a strong gravitational field. Crossing the Event Horizon: The event horizon is the boundary beyond which nothing can escape the black hole's gravitational grip. Interestingly, if you were to cross this threshold, you might not notice an immediate change; however, from an outside observer's perspective, time appears to slow down for you, and you'd seem to freeze at the horizon. This phenomenon is due to the extreme warping of spacetime predicted by Einstein's theory of general relativity. Inside the Black Hole: Once past the event horizon, all paths lead inexorably to the singularity—the core where density becomes infinite and the known laws of physics cease to function. Here, the concepts of space and time become indistinguishable, and the gravitational forces are so overwhelming that escape is impossible. The journey to the singularity would be swift, and the tidal forces would ultimately lead to your disintegration. Note : It's important to note that these descriptions are based on our current understanding of physics, particularly general relativity. The true nature of black holes remains one of the most intriguing mysteries in astrophysics, with ongoing research striving to unravel their secrets. 📹 Credit NASA

Physicist Who Worked at CERN Responds to the Black Hole Conspiracy “These conspiracies are never as cool as they make it sound. They’re just colliding particles, right? You want to send things in at higher and higher energy so they get close enough, and then you can start to see the structure of a thing. They’re not trying to create a black hole. I wish it were that fun. I wish it were that risky. I’d love to be building wormholes, but they’re not going to be transferring anything.”

The United States of America’s military’s thesaurus defines voice to skull V2K devices as follows. Nonlethal weapons which includes 1. A Neuro electromagnetic device which uses microwave transmission of sound into the skull of persons or animals by way of pulse modulated microwave radiation; and 2. A silent sound device which can transmit sound into the skull of persons or animals. Neural electromagnetic devices and V2K are used to send transmissions of sound into the skull through pulse modulated radiation frequency control applications. Different components of V2K can be transmitted by using microwave auditory effects. There are over 100 different ways that have been identified that are used to transmit these frequencies. Through phones, headsets, satellites, and towers, they are almost capable of running through any electronic device that has Bluetooth, radio frequency signals, GPS, etc. There are 100s. A.I. has now completely changed the game and has made the impossible possible. A.I. runs "scripts" using neural networks. The neural networks destroy the neurons in the brain and can not be regrown, causing early alzheimer's disease, memory loss, concussions, seizures, and even permanent brain damage. This is only the tip of the iceberg, and people need to understand what this tech is actually capable of doing and realize it is being used on American citizens and others around the world. This is the ultimate game changer to complete control. Now think what is capable with 1000s of "cell phone" towers being built all across the U.S. and 1000s of satellites being put into orbit. It's all happening right in front of your face, and nobody has a clue. You've been warned.

Black Holes Don’t Simply Suck Things In. They Sort Motion by Geometry. A particle falling toward a black hole is not automatically doomed. Its path depends on how it approaches, the distance, the angle, and the momentum it carries. Some paths cross the horizon. Some skim the edge and whirl around before falling or escaping. Others get sharply deflected and fly back out into space.

Chinese scientists learn to 'read' black holes with world's first spectral index map The team has mapped how radiation from the M87 black hole changes as you move away from its center—like reading its "fingerprint" in space 🔸 Near the black hole, radiation behaves differently than further out—like how light changes when moving away from a fire 🔸 The shift happens at a specific distance, matching the bright ring we see in images 🔸 This proves the famous "ring" is directly linked to the plasma swirling around the black hole 🔸 By combining data from multiple telescopes, they decoded physical properties, not just shapes This moves black hole astronomy from simple photography to true physical analysis—helping understand how these giants pull in matter and shoot out powerful beams across space.

Faraday wave. Visualization of a standing wave. And secrets to some of Nikola Tesla’s work. The water surface is responding to controlled vibration. As the container oscillates at a fixed frequency, energy transfers uniformly into the liquid. Instead of random ripples, waves interfere with each other and form stable standing-wave patterns-repeating circular and hexagonal shapes appearing at specific frequencies where the system reaches resonance. This phenomenon is Faraday wave formation, where small disturbances organize into ordered structures due to periodic forcing. It demonstrates how simple physical inputs produce complex, predictable patterns through constructive and destructive interference. The key mechanism: when oscillation frequency matches the natural frequency of the liquid system, resonance amplifies specific wavelengths while suppressing others. The geometry depends on container shape, fluid properties, and driving frequency. At lower frequencies, you see simple radial patterns. Higher frequencies generate intricate hexagonal and square lattices. These aren't random-they're determined by the wave equation and boundary conditions. The patterns remain stable as long as forcing continues at resonant frequency. Change the frequency slightly, and the pattern transforms or disappears entirely. Faraday waves appear in nature-from vibrating sand to quantum fluids. They reveal fundamental principles: periodic forcing plus wave interference equals spontaneous pattern formation. Simple cause, beautiful complexity.
