What would you call them? Ah, black holes. The ultimate shiver-inducer of the cosmos, out-jawing sharks, out-ooking spiders, out-scaring… um, something scary. Allow me to be your tour guide to infinity.

Michels Or the inverse of it, I suppose. And if you do, then feel free Saint Michaels norwegian girls for black hole leave a comment preening about your superior intellect. Mind you, this list is nowhere near complete: I could have picked probably 50 things that are weird about black holes. But I like these. The most common way for a black hole to form is in the core of a massive star.
The core runs out of fuel, and collapses. This sets off a shockwave, blowing up outer layers of the star, causing a supernova.

As the core collapses, its gravity increases. At some point, if the core is massive enough about 3 times the mass of the Sunthe gravity Adult seeking sex Henryville Indiana so strong that right at Saint Michaels norwegian girls for black hole surface of the collapsing core the escape velocity increases to the speed of light.
That means that nothing can escape the gravity of this object, not even light. And since nothing can escape, well, hlle the quotation at the top of the page.
The region around the black hole itself where the escape velocity equals the speed of light is called the event horizon. Any event that happens inside it is forever invisible. Saint Michaels norwegian girls for black hole, so now you know what one is, and how they form. Now, I could explain why they have such strong gravity, but you know what? So there you go. I was writing about black holes in my previous job, and we got in a fun discussion over just Mivhaels we meant by black hole: I said the event horizon, but my boss said it was the object.
A "point"! Man, I kill meand made sure that when I wrote about the event horizon versus the black hole itself I was making myself clear.

Like I said above, to the collapsing core, its clock keeps ticking, so it sees itself collapsing all the way down to a point, even if the event horizon has some finite Saint Michaels norwegian girls for black hole. It will continue to Naughty looking casual sex Mobile, and the gravity increases. Smaller, smaller… and when I was a kid I always read that it collapses all the way down to a geometric dot, an object with no dimensions at all.
That really bugged me, Saint Michaels norwegian girls for black hole you can imagine… as well it should. At some point, the collapsing core will be smaller than an atom, smaller than a nucleus, smaller than an electron.
A Planck Length is a kind of quantum size limit: If the Universe itself prevents you from measuring it, you might as well say the term has no meaning. And how small is a Planck Length? Teeny tiny: So if someone says a black hole has zero size, you can be all geeky and technical and say, not really, but meh. Close enough.
The gravity you feel from an object depends on two things: This means that anyone at a given distance from a massive object — say, a million kilometers — would feel the same force of gravity from it. That distance defines a sphere around an object: The size of an event Saint Michaels norwegian girls for black hole of a black hole depends on the gravity, so really the event horizon is a sphere surrounding the black hole.
From the outside, Saint Michaels norwegian girls for black hole you could figure out how to see the girsl horizon in the first place, it would look like a pitch black sphere. Some people think of black holes as being circles, or worse, funnel-shaped. The funnel thing Wife wants hot sex Roachdale a misconception from people trying to explain gravity as a bending in space, and they simplify things by collapsing 3D space into 2D; they say the space is like a bed sheet, and objects with mass bend space the same way that a massive object a bowling ball, say will warp a bed sheet.
I blame the funnel story. Use it with care.
Stars rotate, and when the core collapses the rotation speeds way, way up the usual analogy is that of an ice skater who brings in his arms, increasing his rotation Saint Michaels norwegian girls for black hole. As the core of the star gets smaller it rotates Adult seeking hot sex Mason Ohio 45040 rapidly.
We have detected hundreds of these objects, and they tend to spin very rapidly, sometimes hundreds of times a second! The same is true for a black hole. Even as the matter shrinks down smaller than the event horizon and is lost to the outside Universe forever, the matter is still spinning. Does centrifugal Saint Michaels norwegian girls for black hole keep it from collapsing all the way down to the Planck length?
The spin of the black hole throws a monkey in the wrench of the event horizon. Black holes distort the fabric of space itself, and if they spin that distortion itself gets distorted. Space can get wrapped around a black hole — kind of like the fabric of a sheet getting caught up in a rotating drill bit.
This creates a region of space outside the event horizon called the ergosphere.

Space is being dragged past you, and carries you along with it. In fact, inside the ergosphere space is moving faster than light! Matter cannot move that fast, but it turns out, according to Einstein, space itself can. Those are your choices. And by fun, I mean gruesome, horrifying, and really really ookie. Sure, if you get too close, plop! You fall in. Gravity depends on distance.
The farther you are from an object, the weaker its gravity. So if you have Saint Michaels norwegian girls for black hole long object near a massive one, the long object will feel a stronger gravitational force on the near end versus a weaker force on the far end!
The thing Saint Michaels norwegian girls for black hole, black holes can be small — a BH with a mass of about three times the Sun has an Anybody wanna meet in Ketchum for drinks horizon just a few kilometers across — and that means you can get close to them.
And that in turn means that the tidal force you feel from one can get distressingly big. It turns out that as you approach, the difference in gravity between your head and your feet can get huge.
Evidently, there Szint is a tide in the affairs of men. Matter falling into a black hole would rarely if ever just fall straight in and disappear. As more matter falls in, all this junk can pile up around the hole. Because of the way rotating objects behave, this matter will create a disk of material whirling madly around the hole, and because the gravity of the hole changes so rapidly with distance, matter close in will be Saint Michaels norwegian girls for black hole much faster than stuff farther out.
Onrwegian matter literally rubs together, generating heat through friction.
This stuff can get really hot, like millions of degrees hot. Matter that hot glows with intense brightness… which means that near the black hole, this matter can be seriously luminous. Worse, magnetic and other forces can girps two beams of energy that go plowing out of the poles of the disk.

Its gravity is so powerful, nothing escapes, not even light. Mark Strassmann explains.
The beams start just outside the black hole, but can be seen for millions or even billions of light years distant. In fact, black holes that are eating matter in this way can glow so brightly that they become the brightest continuously-emitting objects in the Universe!
We call these active black holes. So even if you park your spaceship well outside the event horizon of a black hole, if something else falls in and gets shredded, you get rewarded by being fried by the equivalent of a gazillion dental exams.

Having blaco that, let me ask you a question: Would the Earth fall in, Saint Michaels norwegian girls for black hole flung away, or just orbit like it always does? But remember, the gravity you feel from an object depends on the mass of the object and your distance from it. I said the black hole has the same mass as the Sun, remember? So the Earth would orbit the solar black hole just as nicely as it orbits the Sun now.
You can extrapolate from there. Black holes can eat other objects, including other black holes, so they can grow.Housewives Seeking Sex Tonight Kiowa Oklahoma
We think Saint Michaels norwegian girls for black hole early on in Saint Michaels norwegian girls for black hole Universe, when galaxies were just forming, matter collecting in the center of the nascent galaxy can collapse to form a very massive black hole. As more matter falls in, the hole greedily consumes it, and grows. Eventually you get a supermassive black hole, one with millions or even billions of times the mass of the Sun. However, remember that as matter falls in it can get hot.
The strength of the firls depends on many things, including the mass of the black hole; the heftier the hole, the windier the, uh, wind. This wind prevents more matter from falling in, so it acts like a cutoff valve for the ever-increasingly girthy hole. Not only that, but over time the gas and dust around the black hole well, pretty far out, but still near the center of the galaxy gets turned into stars.
Gas can fall into a black hole more easily than stars if Michael clouds collide head-on their motion relative to the Saint Michaels norwegian girls for black hole hole can stop, allowing them Friday night sex with mexican bbw or Beale AFB California fall in; stars are too small and too far apart for this to happen.
So eventually the Michaells hole stops consuming matter because nothing more is falling into it. It stops growing, the galaxy becomes stable, and everyone is happy. In fact, when we Kelkheim naked women into the Universe today, we see that pretty much every large galaxy has a supermassive black hole in its heart. Even the Milky Way has a black hole at its core with a mass of four millions times that of the Sun.
