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...

Travis Taylor: "Our Universe lives inside a Black Hole" 😱 “The math keeps pointing to the same place. A black hole between 5 and 10 solar masses, with the best fit right around 7.2.” He arrived at the model by starting with something unexpected: the way video game world maps handle boundaries. That led him to event horizons, then to a Hawking radiation analogy that locked the numbers in place. The paper and the calculations line up on a stellar mass black hole as the container for everything we observe. If the model holds, the edge of our observable universe is not just a light-travel limit. It is the event horizon of a black hole whose mass sits in that narrow 5 to 10 solar mass window, peaking near 7.2. The same mathematics that describe the interior geometry of such a black hole also reproduce the expansion history and the cosmic horizon we measure. It is a clean, testable claim built from the paper’s equations rather than speculation. The numbers either fit or they do not. So far they do.

In April 2019, the Event Horizon Space Telescope managed to take a picture of the black hole M87* in the galaxy M87. The dimensions of the object are impressive: its mass is about 6.5 billion solar masses, and its event horizon radius (the radius beyond which LIGHT cannot escape) is +-120 astronomical units. 1 AU is the distance from the Earth to the Sun.

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

NASA WANTS YOU TO SEE WHAT DYING IN A BLACK HOLE LOOKS LIKE They just dropped a trippy, mind-bending simulation of what it would actually look like to fall into a black hole. Once you pass the event horizon, light can’t escape, time stretches, and space twists until physics gives up. Source: Galaxies

Hubble Records Wandering Black Hole That Swallowed a Star NASA astronomers have recorded a rare event using the Hubble Space Telescope and other observatories — a tidal disruption event (TDE) involving a wandering black hole. It occurred 600 million light years from Earth and provided new insights into the behavior of black holes. The object was spotted due to gravitational lensing — the distortion of light from distant bodies under the influence of gravity. As it approached the star, the black hole tore it apart, creating a bright accretion disk that radiated in ultraviolet and visible light. Unlike typical black holes in the centers of galaxies, this one was located 2,600 light years from the core, where a supermassive black hole was already located. Despite their relative proximity, the two holes do not yet form a single system, but they may merge in the future.

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.

As some of you correctly pointed out, the claim that TON 618 is the largest object in the Universe is now outdated. Recent discoveries have identified Phoenix A, a supermassive black hole with an estimated mass of around 100 billion suns—or possibly even more, as its exact mass has not yet been measured using orbital methods. Phoenix A resides at the center of the Phoenix Cluster of galaxies and boasts some truly mind-boggling features: - Mass: 24,100 times greater than Sagittarius A*, the black hole at the center of the Milky Way. - Scale: Twice the mass of the entire Triangulum Galaxy, including its dark matter halo. - Event Horizon: A Schwarzschild diameter of 590.5 billion kilometers (3,900 AU), roughly 100 times the distance from the Sun to Pluto. - Circumference: Traveling around its event horizon at the speed of light would take 71 days and 14 hours. - Growth: Gains about 60 times the mass of the Sun every year. Given its immense size, Phoenix A might belong to a proposed class of stupendously large black holes —primordial black holes with masses potentially exceeding 100 billion solar masses. Such objects push the boundaries of what we understand about the formation and evolution of black holes, far surpassing the theoretical mass limits of luminous, accreting black holes in spiral galaxies.

NASA used a supercomputer to build a mind-bending simulation of falling into a black hole. Once you cross the point of no return, you have 12.8 seconds left to exist. To visualize these final seconds, NASA scientists ran the math of general relativity on a supercomputer, generating 10 terabytes of data in 5 days. The simulation shows a camera plunging into a supermassive black hole where light warps and space flows inward. The actual descent takes 3 hours, but to a distant observer, your image would freeze at the edge forever. A century of Einstein's equations, finally playing as video.

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

The fastest star in the Galaxy is S4714, which accelerates to approximately 24,000 km/s at its peak, or about 8% the speed of light. It orbits the supermassive black hole Sagittarius A* at the center of our Milky Way, moving in an extremely eccentric orbit. At its closest approach, it comes to a distance of approximately 1.8 billion km from the black hole—comparable to the distance from the Sun to Saturn. From this distance, the angular size of the "shadow" of Sagittarius A* is four times larger than the angular size of the Sun in Earth's sky! Observations of S4714, conducted with the European Southern Observatory, are helping to test the effects of general relativity in the extreme gravity of the Galactic center.
