umm. well It's kind of a long story, but if you know of any can you tell me??
First, the title question: What is being depicted as a flat disc is not the black hole itself, but the accretion disc surrounding the black hole. And that's flat for the same reason that our solar system and our galaxy are more or less flatbecause collisions between particles revolving around the black hole eventually cancel out most of the motion that is not direct revolution. (In other words, up and down motion gets smoothed out.) Whenever I've seen emitted radiation being depicted in a picture of a black hole, it has been symmetric: There is no suck or spit side. Matter goes in at the black hole's equator, more or less, and radiation goes out at the poles. As I understand it, that's basically the way it goes, too. The depictions of black holes that are asymmetric in that way are the rubber sheet curvature-of-space-time mock-ups. These are somewhat misleading, in that what you actually see, when you roll one of those balls around the funnel representing the black hole, is not Einsteinian general relativity, but straightforward Newtonian mechanics. The dimples caused by ordinary masses represent potential energy wells; the funnels represent the bottomless pit of the black holes. Incidentally, you can characterize black holes with just three parameters: mass, angular momentum, and electric charge. Whenever the angular momentum is non-zero, the black hole is said to be rotating, and the simplest general relativity solution for such a situation is called the Kerr solution (as opposed to the Schwarzschild solution, for the non-rotating black hole). In such a solution, the singularity at the heart of the black hole is a ring, not a point. The accretion disc around such a black hole will then align with that ring.
Black holes are a infinitesimal fraction of a pinpoint as one person mentioned. the rationalization some human beings believe it somewhat is a black sphere is by using fact the gravity created by utilising a Blackfoot is so stable that no longer even gentle can escape. So wen we word on in a wavelength of light. Like X-Ray it somewhat is created as a famous guy or woman close to to a black hollow is being ripped aside (spaghettification is the extremely term). by using fact that gentle won't be able to escape it, this creates a extremely black sphere in area. I say black by using fact it is not in all probability something. This factor is the factor of no return for something getting close. the place in the journey that your previous this you'll in no way get out. This factor is termed the progression Horizon. the rationalization you notice a disk shape once you notice photographs, is given it somewhat is termed the Accretion Disk. The accretion disk is a flat plane of count being pulled from interior of sight stars while they get too close. it somewhat is in the previous the skill of spaghettification the place Einstein envisioned wisely that the speedier in direction of the fee of light in a vaccum (ie c) you pass the greater stretched out you will exchange into. additionally you will exchange into greater narrow with starting to be greater elongated.
Sorry kid but you'll have to do both but the Paramedic is just another cert. You will still fight fires but you will also run medical calls as a Paramedic even on the engines and ladders. There are a few major cities like NYC where the FFs only fightfires but the easiest way to get on there is to work as an EMT, then Paramedic with their EMS division and hopefully you can get promoted to be a firefighter.
