How do you make a black hole explode?
The concept of black hole explosions is hypothetical at best and sensationally overrated. The introduction of black hole explosion, promoted by Stephen Hawking and John Wheeler, is basically the calculated event of a dramatic increase in the rate of Hawking emissions upon the onset of black hole death. It would be like a pressure build up in a boiler, except the container is initially able to withstand the bursting event. The notion of black hole death is that eventually the dramatic increase in the rate of Hawking radiation emission reduced the mass of the black hole, and the black hole's energy would evaporate. However, the calculated evaporation time for this type of black hole death is much longer than the current age of the universe at 13.73 ± 0.12 x 109 years.
Can a black hole destroy matter?
Yes - The dense nature of a black hole rearranges and transforms matter into energy. In fact, even before matter crosses the threshold of the black hole's event horizon, the accretion disk of a black hole provides for a formidal barrier. Despite its invisible interior, the presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as light. Matter falling onto a black hole can form an accretion disk heated by friction, forming some of the brightest objects in the universe.
What does a black hole do with what it suck in?
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
Can any black hole turn into a neutron star?
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
Sentence for black hole?
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
Presence of black hole can be by the emission of ------- rays?
The extreme energies associated with matter falling into a black hole often excite it enough to produce characteristic x-ray emissions.
Is a black hole so bright that we cant see it?
Quite on the contrary - it's so dim that we can't see it: no light escapes from the hole. The only emission indicating presence of a black hole may come from accreting matter surrounding a hole. Although Hawking's radiation is associated with event horizon, it is undetectable at such distances.
Was the black hole discovered 400 years ago?
No. The idea of a black hole was first proposed in 1783, 230 years ago. The first observations believed to indicate the presence of a black hole were in 1964.
What happens if a black hole gets destroyed?
There is no way you can *quickly* destroy a *large* black hole. However, it is believed that black holes will gradually evaporate, via the emission of Hawking radiation. The radiation, in this case, will simply go out into space.
What is the closest black hole to Pluto?
It is actually difficult to determine the distance to black holes, but a nearby object believed to be a black hole from observations of strong X-ray emission is Cygnus X-1, located about 8000 light years away. Cyg X-1 is an ordinary star that is believed to be orbiting a black hole.
What band of radiation is best for studying black holes?
X-rays are the best band for studying black holes as the radiations emitted by the black hole is X-rays so we can expect the presence of a black hole anywhere in the Universe.
Why can't we see black holes what would it look like?
We cannot see black holes because no light comes from them1. They are so gravitationally massive that even light cannot escape from a black hole, thus the name black hole.1 While there is an emission of matter and energy, called Hawking radiation, that theoretically radiates from the perimiter of a black hole, no energy of any kind (including Hawking radiation) escapes from inside the black hole.
How can astronomers tell if a black hole exists?
Since black holes allow nothing including light to escape, astronomic detection needs to be indirect. Common methods to detect black holes include the observation of the effects of their gravity upon nearby objects; such a technique was used to interpret compelling evidence of the presence of the supermassive black hole at the Milky Way's center, and included measurements of the orbital period and distance from the source of gravitational pull. In this case the calculated mass was so great, and the orbit of the nearest star so close, that nothing described by physics could be as compact or massive except a black hole. Another method is the detection of a characteristic signature of radiation emitted by matter falling into the black hole. Their presence can also be inferred from the radiation created by the accretion disk and the polar relativistic jets in some circumstances. Gravitational lensing may also indicate the presence of a black hole although other possible causes would need to be eliminated, such as the presence of intervening dark matter. Gamma ray bursts may also indicate the birth of a black hole, and also searches are underway for energy emissions possibly associated with their death. Often the gathering of a scientific consensus regarding the presence of a black hole can only be achieved with prolonged observation.

A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a black hole.
Can your car pass emission inspection with a hole in the muffler in new york?
no.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.
