Classically, black holes are perfect absorbers but do not emit anything; their physical temperature is absolute zero. However, in quantum theory black holes emit Hawking radiation with a perfect thermal spectrum.Because of the fuzziness of quantum particles, energy cannot be completely bound by a black hole's event horizon. Sometimes energy can escape its gravitational prison through a process known as Hawking radiation. The amount of energy that escapes is tiny, but it means that black holes have a (very cold) temperature.The sound produced by a black hole collision, if it were able to travel through a medium like air, would be deafening. The frequency of the gravitational waves generated by a black hole collision is so low that it falls outside the range of human hearing.
Do black holes emit light : Black holes don't emit or reflect light, making them effectively invisible to telescopes. Scientists primarily detect and study them based on how they affect their surroundings: Black holes can be surrounded by rings of gas and dust, called accretion disks, that emit light across many wavelengths, including X-rays.
Do white holes exist
White holes are the opposite of black holes, in that they spit out light and matter, rather than trapping it. So far, white holes are purely hypothetical objects, but astronomers are contemplating how they could form in reality.
What is hotter black hole or sun : Hence, yes, the black hole will be hotter than the Sun if you are hovering sufficiently close to it. Furthermore, there is no limit on the black hole's mass: this will be true for a black hole of any size, as long as you are close enough. Notice an important point: the temperature depends on the observer measuring it.
White holes are the opposite of black holes, in that they spit out light and matter, rather than trapping it. So far, white holes are purely hypothetical objects, but astronomers are contemplating how they could form in reality. The hottest spot in the universe may well be near the edges of a supermassive black hole. While the sun is the most scorching object in our solar system, its temperatures pale in comparison to several other cosmic bodies.
Can black holes hurt us
We are in absolutely no danger from black holes. They're a bit like tigers – it's a bad idea to stick your head in their mouth, but you're probably not going to meet one on your way to the shops. Unlike tigers, black holes don't hunt. They're not roaming around space eating stars and planets.Converting the energy of 1,100 decibels to mass yields 1.113×1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila! No more universe.A supermassive black hole heats gas falling onto it to temperatures of millions of degrees, making it glow brightly enough in X-rays and other types of radiation to be seen across the universe. Very common. A Q-star, also known as a grey hole, is a hypothetical type of a compact, heavy neutron star with an exotic state of matter. Such a star can be smaller than the progenitor star's Schwarzschild radius and have a gravitational pull so strong that some light, but not all photons, can escape.
Is red hole real : Researchers have discovered an extremely red supermassive black hole thanks to the help of some gravitational lensing. Researchers used the James Webb Space Telescope to detect an extremely red, gravitationally lensed supermassive black-hole in the early Universe.
What’s the hottest thing in space : The hottest objects in the universe are believed to be the cores of stars, particularly during their final stages of life. The core of a massive star during its supernova phase can reach temperatures of around 100 billion Kelvin (100 billion degrees Celsius, or 180 billion degrees Fahrenheit).

For a black hole observer, one hour is equivalent to 100,000,000 years on Earth. In contrast to time distant from a black hole, time moves more slowly as you approach closer to one.In general, the noise produced by a nuclear bomb can reach levels of up to 240 decibels at its epicenter. This is equivalent to standing next to a rocket launch or a powerful jet engine. The sound is so intense that it can rupture eardrums, cause permanent hearing loss, and even lead to death in extreme cases.
Why is 194 dB the loudest sound possible : Once you get to a certain level (194 decibels, to be precise), there comes a point where the low-pressure regions are completely empty – there are no molecules in there at all. The sound can't get 'louder' than that, technically.
