Hawking radiation is the theoretical thermal black-body radiation released outside a black hole's event horizon. This is counterintuitive because once ordinary electromagnetic radiation is inside the event horizon, it cannot escape.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.Eventually, in theory, black holes will evaporate through Hawking radiation. But it would take much longer than the entire age of the universe for most black holes we know about to significantly evaporate. Black holes, even the ones around a few times the mass of the Sun, will be around for a really, really long time!
What is a grey hole : 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 if we nuke a black hole : Black holes only care about gravity. Which only depends on the total mass energy of an object. And the mass of a particle is the same as its corresponding anti-particle.
At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. It turns out that this is only true for a few of them: most have the wrong colours to be expained by this. 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.
Are we 100% sure black holes exist
There is consensus that supermassive black holes exist in the centres of most galaxies. The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light.The fate of anyone falling into a black hole would be a painful “spaghettification,” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules.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. Black holes seem to be the stuff of science fiction (and, in fact, have starred in many sci-fi books and movies), so it's not uncommon for people to wonder, are black holes real As it turns out, the answer is yes, though for a long time most scientists were convinced that black holes were purely theoretical objects.
Is black hole scary : Black holes are some of the most mystifying and terrifying objects in the universe. They have a gravitational pull that is so strong that nothing – not even light, the fastest object – can escape it.
Is a black hole painful : Your body stretches out, not uncomfortably at first, but over time, the stretching will become more severe. Astronomers call this spaghettification because the intense gravitational field pulls you into a long, thin piece of spaghetti. When you start feeling pain depends on the size of the black hole.
Are we inside a black hole
Earth is not just tucked into a planet-size black hole or even one the size of the solar system. If that were the case, scientists would have noticed, Field told Live Science. There would be observable signatures of the black hole's spinning. When matter falls into or comes closer than the event horizon of a black hole, it becomes isolated from the rest of space-time. It can never leave that region. For all practical purposes the matter has disappeared from the universe.Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely Earth would fall into a black hole because, at a distance, their gravitational pull is no more compelling than a star of the same mass.
Does time exist in a black hole : From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole. Inside a black hole is where the real mystery lies. According to Einstein's theory, time and space, in a way, trade places inside the hole.
