Black holes are very cold. In effect the new formula counts the holes of a black hole and the spacetime that surrounds it (yes, even black holes have holes in them). Taking a black hole’s temperature is a seemingly impossible task. Naively you'd expect that a black hole would be at absolute zero. The Hawking temperature (Hawking, 1974) is the black body temperature at which a black hole emits radiation due to quantum effects close to the event horizon. « Reply #13 on: 10/04/2012 16:25:49 » I think some Idea of temperature could be obtained by applying the consevation of energy rule assuming the the originol star that collapsed had a mass of 10^32 Kg a density of 1 and and average tempurature of 10,000 °K when compressed to QGP density the temperature would go up in proprtion. Re: What is the temperature inside a Black Hole? The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero. The more massive it is, the lower its temperature, although it’s still not zero. Temperature is in degrees Kelvin. In 2015, researchers discovered a black hole named CID-947 that grew much more quickly than its host galaxy.

The Hawking temperature (Hawking, 1974) is the black body temperature at which a black hole emits radiation due to quantum effects close to the event horizon. By the Stephen Hawking it should be very near to the absolute zero. A black hole about the mass of the Moon would have a temperature around 2.7 kelvin.

Jul 12 '18 at 23:19 But now, physicists report the next best thing. A black hole behaves as though its horizon has a temperature and that temperature is inversely proportional to the hole's mass: T = (6 x 10^-8)M. Here M is in units of solar mass (2 x 1033 grams). So yeah, the black hole will appear cooler to an observer further away from the black hole. The black hole at the galaxy’s center is nearly 7 billion times the mass of our Sun, placing it among the most massive black holes discovered. That’s low. Taking a black hole’s temperature is a seemingly impossible task. In mid-May, a supernova black hole at the center of our Milky Way galaxy became 75 times brighter within a span of two hours, and scientists have yet to … A black hole has a temperature. In this video we are discussing what is the temperature inside the Event Horizon of a Black Hole. The closer you are at the black hole the greater the temperature of the black hole you measure while if you are at infinity, you measure the Hawking temperature. Let’s try another way to think about this. This means you could take some hot mass and collapse it into a black hole… Temperature is inversely proportional to mass When a black hole reaches zero mass, it is thought to explode in a blaze of gamma rays Some LHC scientists hope they can produce some tiny black holes, and this temperature could then be measured to confirm the theory Thermodynamic black holes have not … Physicists created a sonic black hole in the lab and then took its temperature — and the measurement seems to confirm a prediction made by Stephen Hawking. The most massive black holes in the Universe, the supermassive black holes with millions of times the math of the Sun will have a temperature of 1.4 x 10 -14 Kelvin.
