Well, a vacuum cleaner sucks things up and a black hole sucks up and destroys things, so you could call it a cosmic vacuum cleaner. However, a black hole cannot be seen and is invisible. However, I learnt that when a star is going from very bright to not so very bright, a black hole is ripping apart the gas from the star. If you ever see a star going less bright from when it is very bright, a black hole is sucking the gas from it.
Somewhat but not exactly, a black hole does not use the same physics as a vacuum cleaner, a black hole is the warping of space/time caused by the mass that it contains, the attraction of matter towards a black hole is only based on how much mass and warping of space time the black hole causes. In a vacuum cleaner you always know where all the trash is going to end up, in a black hole we do not know exactly what happens inside. If a black hole does not receive matter it will eventually get rid of that matter in the form of radiation called hawking radiation, and when it radiates more energy than it consumes then it eventually evaporates.
NO. Black holes are really NOT cosmic vacuum cleaners. ...Black holes: What are they? Black holes are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun. If a star that massive or larger undergoes a supernova explosion, it may leave behind a fairly massive burned-out stellar remnant. With no outward forces to oppose gravitational forces, the remnant will collapse in on itself. The star eventually collapses to the point of zero volume and infinite density, creating what is known as a singularity. Around the singularity is a region where the force of gravity is so strong that not even light can escape. Thus, no information can reach us from this region. It is therefore called a black hole, and its surface is called the event horizon. But contrary to popular myth, a black hole is not a cosmic vacuum cleaner. If our Sun was suddenly replaced with a black hole of the same mass, Earth's orbit around the Sun would be unchanged. Of course, Earth's temperature would change, and there would be no solar wind or solar magnetic storms affecting us. To be sucked into a black hole, one has to cross inside the Schwarzschild radius. At this radius, the escape speed is equal to the speed of light, and once light passes through, even it cannot escape. The Schwarzschild radius can be calculated using the equation for escape speed: vesc = (2GM/R)1/2 For photons, or objects with no mass, we can substitute c (the speed of light) for Vesc and find the Schwarzschild radius, R, to be R = 2GM/c2 If the Sun was replaced with a black hole that had the same mass as the Sun, the Schwarzschild radius would be 3 km (compared to the Sun's radius of nearly 700,000 km). Hence the Earth would have to get very close to get sucked into a black hole at the center of our Solar System. If we can't see them, how do we know they are there?... imagine.gsfc.nasa /docs/scienc...
haha, exciting analogy! i'm happy you secure the actuality in regards to the form horizon, maximum human beings think of a black hollow can save on 'sucking' stuff in. of direction, a vacuum purifier does not %. each and every little thing into an infinite density on the singularity (that would improve your electrical energy invoice!), and black holes do no longer could be plugged in, use a bag, or be human-powered. So no longer precisely, yet your on the superb song for documents how they artwork. i wish that enables!
No for two reasons 1) Vacuum cleaners do not work in a vacuum. 2) There are no 13A sockets in space
