perhaps we may one day see stages of stars turning into "dark stars", perhaps large stars getting fainter quickly is this process? the density of this central "star" is hard for us to imagine, so scientist describe it as a singularity, a "dot" ? we just do not know. so if you had a crush proof ship, and allowed your ship to get pulled in, past the "event horizon", you would most likely see the bright star and at the center. Imagine a star getting bigger and bigger, pulling in more mass, eventually it would be so massive, it would start pulling back into itself emitted solar flares, then eventually all of its emissions would be pulled back into itself, even light! at that stage, an outside observer would see the "star" disappear except for external matter being pulled into it, orbiting it, etc. it is not a 2 dimensional disc like hole. The label "black hole" is a bit of a misnomer, misleading name. What Gravitational Waves Have Taught Us about Black Holes.How Did Astronomers Image a Black Hole?.Scientists Unveil First Black Hole Image.This Q&A is adapted from the February 2017 infographic “Anatomy of a Black Hole.” Further Reading So your image would redden and dim with time, until it faded entirely. But in practice you would disappear: the photons lose energy as it becomes harder for them to climb out of the black hole’s gravitational well nearer the event horizon, and their wavelength would increase until it grew past the observer’s detection capabilities - making the image invisible. Theoretically, at the event horizon your image would freeze. What would someone watching see as you fell in?Īs you approached the event horizon, a second person far, far away would watch your image slow down and redden. But as you drew closer to the singularity, gravity should stretch and squeeze you as if you were dough in a bread machine. Passing the event horizon, you wouldn’t notice much ( except some fun light effects and several extra g’s of gravity). So let’s travel into a supermassive black hole. The tidal forces become too strong too fast for you to survive to the event horizon, resulting in your spaghettification (yes, that’s the technical term). That’s because, if you think of a black hole as a pit, a stellar-mass black hole has steeper sides than a supermassive black hole. If it were a stellar-mass black hole, you’d be dead before you passed the event horizon. What would happen if you fell into a black hole? But those conditions almost certainly would never exist in the real universe. Wormholes are theoretically possible, given the right conditions. It could be that, in real black holes, singularities don’t even exist. Others say that the singularity is actually a whole surface inside the event horizon. But that mathematical situation won’t exist in reality. In a very specific mathematical case, the singularity in a spinning black hole becomes a ring, not a point. Some people talk about it as a point of infinite density at the center of the black hole, but that’s probably wrong - true, it’s what classical physics tells us is there, but the singularity is also where classical physics breaks down, so we shouldn’t trust what it says here. A singularity is what all the matter in a black hole gets crushed into. One thing’s for sure, though: the tidal forces would kill you (see below).Īccording to theory, within a black hole there’s something called a singularity. It might be turbulent, twisted, or any other number of things. Calculations suggest that what the fabric of spacetime looks like inside a black hole depends on that particular black hole’s history. Inside the event horizon is where physics goes crazy. The event horizon is where the escape speed exceeds the speed of light: you’d have to be going faster than light (which is impossible for any bit of matter) to escape the black hole’s gravity. We understand what happens outside the black hole as you approach its event horizon, that infamous point of no return. The short answer is, physicists don’t know.Ī somewhat longer answer is, it depends on whom you ask. Artist's illustration of the silhouette of a black hole surrounded by stars.
