How high can temperatures naturally rise? I was watching a documentary about UFOs, and they were discussing fragments of a ship that had allegedly crashed in Roswell. The narrater noted that there was evidence that the fragments had been subjected to temperatures that far exceeded our own Sun. Whether you believe any of that story is irrelevant - what I'm asking is: what's hotter than the Sun/stars? What is the temperature of, for example, the center of a Black Hole? that would have worked if you hadn't stopped me |

from Lightning wiki
So yes, whether it was an extraterrestrial craft, experimental aircraft or project mogul balloon, it may indeed have experienced temperatures many times that of the surface of the sun. (from a lightning strike) ..As to black holes... well i dunno :D "Living by the wisdom of computer science doesn't sound so bad after all.

Back in the sixties (or whenever we blew up our last- or one of our later- hydrogen bomb(s)) Life Magazine said ..Five Times Hotter Than the Center of the Sun" and said that the temperature of (the center?) of that fireball was about 100,000,000 degrees Fahrenheit (about 55,555,555C). So the center of the Sun is much hotter than its surface. I even recently read (in the past decade or so) the the center of the Earth might be hotter than the surface of the Sun. |

what's hotter than the Sun/stars? What is the temperature of, for example, the center of a Black Hole? The "hottest temperature" (Planck Temperature) that our known universe has experienced, in theory, is about 10^32 Kelvin at the onset of the BB. What the temp was at singularity is unknown since singularity only exists to us as a mathematical construct where all our known laws break down. |

Long time no post for me but here's my thoughts on this... It seems wonderfully strange that we have determined Absolute Zero to be 0 K (–273.15 °C or -459.67 °F), which does not seem all that much colder than the ideal conditions for life when compared to the highest observed temperatures in the universe. Remembering as well that the range of temperatures is so large. One might say that the conditions required for life are cold, the conditions required for human life are only very, very, very slightly warmer.

Do you recall where you read this? I read within the past 1-2 months an article in Discover magazine about different theories about the core of the Earth (and layers above it, as well), but I do not think there was any suggestion of the core being much hotter than the surface of the Sun ... ? Capitalize on this good fortune, one word can bring you round ... changes. |

I read that the center of the Earth is about 12,000 degrees Fahrenheit several years ago, but don't know from what source. Possibly it was from "Sky and Telescope". Chances are it was from just one article- and other articles might give different temperatures. My memory is poor but that core might be mostly iron, and maybe solid. Extreme pressure (but not extreme on an astronomical basis) probably changes the properties of superheated metals a whole lot. I would guess that the pressure at the center of Earth might be half the weight of an inch-square column of Earth the radius long, since gravity decreases to zero at the center. But it would be even less than that because the core is denser than the average (5.5 g/cm^3). If it would be 1/3 the weight, I would get 1/3 * 5.5 * 62.3/1728 * 3950 * 63360 or about 16.5 million psi. |

Estimates of the temperature of the earth's core are between 5000C and 7000C. http://www.newton.dep.anl.gov/askasci/env99/env281.htm The temperature of the photosphere of the sun is about 6000C. http://www.solarviews.com/eng/sun.htm The two temperatures are roughly the same. https://youtu.be/iY57ErBkFFE #Texit Don't blame me, I voted for Johnson(L) in 2016.
