So the title of this video is "What would happen if the

temperature somewhere reached 142 Nonillion

degrees. Which for reference has this many zeros. (30)"

The answer is weird, but to prepare you for it,

we need to start with some weird things that start at much lower temperatures.

We can begin our journey at

-273.15 degrees Celsius

also known as absolute 0 or the

coldest possible temperature in the universe.

In 2003, scientists at MIT came very close

to achieving this temperature when they got just within a billionth of a degree

above the limit. That means that the coldest

temperature ever observed anywhere in the universe

was actually just right here on Earth in this laboratory.

And just barely above that at

-273 degrees is the lowest temperature ever survived

by a living thing. The cute but almost indestructible

tardigrade or water bear. Once we get a little warmer

to -216 degrees we arrive at the coldest

planet in the solar system, Uranus. Warmer still

at -184 degrees is the average surface temperature

on the dark side of the moon, and just one degree

higher is when oxygen starts to boil. Earth is

comparatively much warmer than most other planets

because the coldest temperature ever measured here naturally was

-89 degrees taken at the Vostok Station in Antarctica.

The lowest temperature

ever recorded in the US was -62 degrees in Alaska.

Which is even colder than the average surface temperature of Mars is

At negative 55 degrees

Finally at 0 degrees we reach the melting point of ice,

And just slightly higher at 13.7 degrees is the lowest body temperature

a living human has ever had.

The average human body temperature is 37 degrees,

and 46.5 degrees is highest recorded

body temperature that a person has survived.

57 degrees is the highest temperature

recorded in the US taken in Death Valley,

while 71 degrees is the highest surface temperature ever measured anywhere

On our planet, taken inside of Iran.

But there are places out there in the universe that are far hotter

than anywhere on Earth

Despite how cold the moon is on the dark side

The average temperature where the sun does shine

is a sweltering 101 degrees

despite these 2 opposite climates

the tardigrade i mentioned earlier can survive either of them

The highest temperature that one has survived was

an amazing 151 degrees

But the universe still gets way hotter

462 degrees is the average surface temperature

of the planet venus

the hottest planet in our solar system

raising the heat even more up to 1027 degrees

and we get to the maximum temperature of a flame burning from wood

lava freshly erupted from a volcano can hit 1200 degrees

but candles can burn even hotter

up to 1400 degrees

eventually we hit the boiling points of silver

iron and carbon

and at 5000 degrees we reach the temperature

inside the initial blast of a conventional chemical bomb

the temperature you would encounter at the surface of the sun

may seem very high at 5500 degrees

but the temperature inside of the Earth's core

is even hotter at 6000 degrees

but hotter than either of those is the temperature inside

the fireball of a nuclear explosion

which can be up to 10000 degrees or even more

But outside of the sun's surface the sun's upper atmosphere can reach an unbelievable

1 million degrees

Down at the sun's core the temperature can reach an even more insane

15 million degrees

but that's nothing compared to the heat generated from the blast of a supernova

When a star enters a supernova state

it heats the gas around it to a mind-boggling

55 million degrees

When smaller stars collapse into neutron starts though

the newly formed neutron core has a temperature approaching

100 billion degrees which is 6666

times the temperature found inside the sun's core

But the hottest temperature ever recorded anywhere in the universe

was right back here on Earth

created by scientists at CERN in Switzerland.

Using the large Hadron Collider, they created

extremely fast collisions of lead ions that briefly generated

a temperature of 5.5 trillion degrees

which sounds like a lot but it was limited

to a very tiny areas around where the ions collided

but the hottest temperature that might be possible in the universe

is completely unbelievable.

142 Nonillion degrees

is the temperature at which our conventional understanding

of physics begins to break down. In theory

the is no limit as to how much energy we could put into

heating something up, but there so far is no

scientific theory for how matter might

behave at this high of an energy level

We simply don't know what would happen if we managed to

heat something up this hot. But we can speculate a little.

This temperature is known as the Planck Temperature

because the radiation emitted from an object this hot

would have a wavelength equal to the Planck Length

A distance so unbelievably small that we don't know

how or if we can measure distances that are smaller

because you would be condensing so much

energy into such a small point, going beyond

the Planck Temperature could be enough to turn the area

or thing you were heating into a black hole

Creating a black hole with energy instead of mass like this is called

a Kugelblitz and it could pretty quickly become a bigger problem

than what ever damage the heat would have caused to you

Our math so far can't describe exactly what would

happen if we went beyond the Planck Temperature

it may create a black hole that would instantly radiate away or it could destroy the Earth.

Or it may do something else completely unexpected by anyone

The mathematical models that we've developed so far

are incapable of explaining it, but if you'd like to take your shot at it

and go down in history as a scientist celebrity

you'll need an understanding of things like Calculus

Quantum Mechanics and general relativity the numbers

and concepts that go into learning these things are hard and confusing

for a lot of people including myself, but taking the courses

over at Brilliant has helped me enough to feel confident

in making videos like this one. Rather then

telling you how to do Calculus by making you memorize things

they start by teaching you the intuitive ideas beyond

Calculus by playing through their puzzles you'll come

to understand how Calculus actually works

and Brilliant has tons of relevant courses to help you

learn more about how our universe really works

like Gravitational Physics, Quantum Objects, and Einstein's special

theory of relativity. All of which similarly guide you along as you

build your core knowledge. You can take as many of these

incredibly designed courses as you want
