The team then observed the very brief formation of the quark-gluon plasma, which turned out to be a nearly frictionless fluid with a temperature of 4 trillion degrees Celsius (7.2 trillion degrees Fahrenheit), a feat that has now been recognized by the folks at Guinness.
The hottest temperature ever recorded was 134 degrees (56.67 degrees Celsius) in July 1913 at Furnace Creek, said Randy Ceverny of the World Meteorological Organization, the body recognized as keeper of world records.
The hottest thing that we know of (and have seen) is actually a lot closer than you might think. It's right here on Earth at the Large Hadron Collider (LHC). When they smash gold particles together, for a split second, the temperature reaches 7.2 trillion degrees Fahrenheit.
A supernova is the hottest thing in the universe. The temperatures at the core during an explosion skyrocket up to 6000X the temperature of the sun's core.
Different parts of our body have different temperatures, with the rectum being the warmest (37℃), followed by the ears, urine and the mouth. The armpit (35.9℃) is the coldest part of our body that is usually measured.
A wet-bulb temperature of 35 °C, or around 95 °F, is pretty much the absolute limit of human tolerance, says Zach Schlader, a physiologist at Indiana University Bloomington. Above that, your body won't be able to lose heat to the environment efficiently enough to maintain its core temperature.
Temperature. The more massive a black hole, the colder it is. Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
The highest temperature ever recorded in Australia is 50.7 °C (123.3 °F), which was recorded on 2 January 1960 at Oodnadatta, South Australia, and 13 January 2022 at Onslow, Western Australia. The lowest temperature ever recorded in Australia is −23.0 °C (−9.4 °F), at Charlotte Pass, New South Wales, on 29 June 1994.
1. Marble Bar, Western Australia. Marble Bar claims to be the hottest town in Australia. It holds the record for the highest average monthly maximum temperature, which is 41.5°C in December.
Is Australia hotter than India? India is closer to the equator as compared to Australia, and is therefore expected to be hotter. The average temperature in most of the interior regions of India is 90–104 °F. Whereas in Australia the average temperature in summer is 86 °F.
Evidence of warming in Australia
Australia's climate has warmed since national records began in 1910. Australia's average temperature has increased on average by 1.44 ± 0.24 °C since national records began in 1910. Since 1950, every decade has been warmer than the decade before.
Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole. This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.
Given how many black holes we expect are out there and how long our Solar System has been around, that's only about a ~0.000000001% chance, or 1-in-100 billion, that any planet would encounter a black hole over the past 4.5 billion years.
Death by black hole
No material that falls inside a black hole could survive intact. Unfortunately, because nothing can escape a black hole's event horizon — not even information — we'll never know for certain what happens when matter falls past the point of no return.
It could be fatal. It is commonly held that the maximum temperature at which humans can survive is 108.14-degree Fahrenheit or 42.3-degree Celsius. A higher temperature may denature proteins and cause irreparable damage to brain.
A deep red fire is about 600–800° C (1112–1800° F). An orange-yellow fire is about 1100° C (2012° F). A white flame is hotter than both, having temperatures of 1300–1500° C (2400–2700° F). A dazzling white flame is the hottest flame of all, with a range of 1400–1650° C (2600–3000° F).
For many dogs, outdoor activity at temperatures above 82°F can be dangerous, and for some dogs even temperatures in the 70°-77° range can be too hot.
Since the Milky Way contains over 100 billion stats, our home galaxy must harbor some 100 million black holes. Though detecting black holes is a difficult task and estimates from NASA suggest there could be as many as 10 million to a billion stellar black holes in the Milky Way.
There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.
We might be the product of another, older universe. Call it our mother universe. The seed this mother universe forged inside a black hole may have had its big bounce 13.8 billion years ago, and even though our universe has been rapidly expanding ever since, we could still be hidden behind a black hole's event horizon.
It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.
Since nothing can escape from the gravitational force of a black hole, it was long thought that black holes are impossible to destroy. But we now know that black holes actually evaporate, slowly returning their energy to the Universe.
In pure general relativity, with no other modifications or considerations of other physics, they remain black for eternity. Once one forms, it will just hang out there, being a black hole, forever.
2100: Either uninhabitable or beginning to repair
Over the coming two decades, extreme weather is set to disrupt society with increasingly severe bushfires, drought and storms. The good news is by the end of the century, living on Earth could actually be more pleasant than it is today.
The mobile-friendly MyClimate 2050 tool shows almost all areas across Australia will experience longer and hotter summers, with temperatures increasing by an average of 2.32°C.
