![]() Its diameter is estimated to be around 23.6 billion miles (38 billion kilometers) across! You Are Breakfast, Lunch, Brunch and/or Dinner: Previous estimates suggested it was between 3.5 billion and 7.22 billion solar masses, but it's actually closer to 6.5 billion solar masses (one solar mass is the mass of the Sun, 1.989 × 10 30 kg) - meaning this black hole is huge by black hole standards. In addition to behaving in the way Einstein predicted, the Event Horizon Telescope team was able to measure the behemoth black hole in the core of M87. Thanks to the discovery, and subsequent imaging, of a black hole located in M87, about 55 million light-years from Earth, in 2019, science has once again shown that Einstein's theory was on the right track. Friction happens within the disk, which generates large amounts of light radiation that can be seen and measured by astronomers. Sometimes, more matter collects around the event horizon than the black hole can take in at once, so it all gathers in orbit around the black hole and forms an accretion disk. The theory of general relativity also gave rise to the prediction of black holes: Infinitely dense points in space, surrounded by event horizons, where nothing - not even light - can escape. Rendering that shows the warping around Earth that demonstrates gravity Source: NASA/MSFC/Stanford University artist's concept The larger and more dense the object, the stronger the gravitational pull. This warping leads to our most basic understanding of gravity - it is the result of the warping of spacetime. Much of what Einstein proposed in the theory has since been confirmed by experiments, such as one that showed the fabric of spacetime is warped by objects with extreme gravitational fields (which was originally done by observing the bending of light during a solar eclipse). A result of a black hole’s gravity having a substantially stronger pull on its victim’s feet versus their head.Although Einsteing himself argued against the existence of black holes, their existence was originally derived from Einstein's formulation of what is now known as the theory of general relativity, which is one of the most important theories in the history of physics. A phenomenon that astrophysicists refer to as spaghettification because of the way it stretches the body. ![]() ![]() Roussel’s translated narration notes after that point, it’d be a matter of milliseconds before the object’s gravity tore us apart. Once we cross the black hole’s point of no return-its “event horizon”-things grow gruesome very quickly. (An analogy for the effect is when rain falls straight down on a car, but ends up leaving traces at an angle on its side windows.)Īs we continue on toward the black hole at about 4% the speed of light, it ultimately only takes up 15% of our field of view again, a consequence of light abberation. This is because we’re moving toward the black hole, and peripheral light stretches out in front of us. In other words, we as the observer receive light coming from the plasma around the black hole “squashed toward the front” of our field of view. ![]() This is intentional, as it represents the phenomenon of light abberation. ScienceClic EnglishĪs Roussel notes in an explanation on YouTube, at no point does it look like we’re ever actually entering the black hole. the place where the black hole’s mass compresses matter down to an infinitely tiny point. The video shows the fall from approximately 15 times the black hole’s radius all the way down to its singularity. Using “true” general relativity calculations as the basis for the visualization. In the video Roussel treats us to a first-person look at what it’s like to fall into a black hole haloed by bright plasma. ![]()
