Nerd Glasses Moment #1: Aurelion Sol is hottest grill.

Welcome to the first ever edition of Nerd Glasses Moment, a segment in Memes and Games where I will over-analyze and make scientific sense out of trivial things and answer reader's questions in the most drawn out ways (with humor of course, this is M&G after all.)

This episode is brought to you by:

1. Face The Sun, for making the I Think We Can All Agree Post.
2. MavenSong for getting into a lengthy talk with me in said post about who is the "hottest grill", sparking this idea.
3. ZT Xperimentor who, asked about , specifically his heat generating potential. Here is his request...

> Probably his ability to create stars, [sic]. Plenty of heat is involved with extreme compression or excessive mass.

So that is what we will be covering today. How hot is Aurelion Sol?

Good Question.

Well first we have to consider what he is, a Celestial Being, specifically a Celestial Dragon. Capable of creating stars at will, he is said to have populated the vast cosmos with stars and is basically the equivalent of a Runeterran God. Which means that we will not be trying to decipher his physiology and how he can create stars and live and what he eats and such.

We will only be focusing on how hot he can get, defined in this post as the temperatures that he can create in his stars and by extension withstand.

So let's begin with the question, "What is heat?"

According to Dictionary.com:

> [Heat is] Internal energy that is transferred to a physical system from outside the system because of a difference in temperature and does not result in work done by the system on its surroundings. Absorption of energy by a system as heat takes the form of increased kinetic energy of its molecules, thus resulting in an increase in temperature of the system. Heat is transferred from one system to another in the direction of higher to lower temperature.

This is not to be confused with Temperature, which is defined as:

> the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

Basically, "heat" is the word used for the internal energy inside an object that vibrates the atoms of the object at a certain speed. The energy is transferred from one thing to another depending on the difference of their internal atom vibrations with the intent of reaching a balance.

"Temperature" is the word we use when we put heat on a scale and measure it in degrees, otherwise the concept of "heat" besides the physics of it are subjective. For example a 70 degree F day outside would be hot to someone who grew up in Alaska, but cool to somebody who was raised in Arizona. This is why we use a temperature system, because "hot" and "cold" mean different things to different people.

Now that we got the definitions out of the way, back to the "Star" of the show.

According to skyandtelescope.com, a star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity.

A star's life begins as part of massive gas clouds floating throughout space.

Now these clouds aren't very hot. They are about 10 Kelvin, which is a temperature scale designed to cover both the highest and lowest temperatures possible in the universe. So yeah, not looking too hot there Sol.

Now some kind of gravitic disturbance has to happen in the victinity, like say a shockwave from a supernova some distance away.

The gas clumps inward, and as it expands it pulls more and more gas into it due to gravity. The gravity from a clump large enough mass-wise to have any is small indeed, but in the middle of space you don't have much competition so the ball of gas gets larger and larger, and in the process pulls surrounding gas in faster and faster.

Now while all this is happening the very center of the gas cloud is being pressed tighter and tighter from all the gas on the outside squeezing in on it. So it starts to heat up and rotate slowly. Eventually the center is collapsed tight enough, and the heat generated is high enough that the material starts to rotate faster and faster. The bright disc in the center of the gas cloud (flattened into a disc by the now very fast rotation) pulls in material faster and faster, and the material generates a ton of heat as it is pulled into the disc, going around the edges before getting pulled to the very center.

Eventually the material falling into the disc gathers into a white-hot dense core, called a protostar. This protostar now sits at the center of the disc, gobbling up the material fed to it by the disc greedily.

Once this protostar reaches 7 million Kelvin, (To compare, 90 Degrees F is about 305 Kelvin) Hydrogen begins to fuse to create Helium, and the massive energy created makes the protostar start to shine brighter and expand. However this isn't enough for the star to become a fully fledged star, as it isn't big enough. Material will continue to fall into the star for a few million years until the proto star reaches at least a tenth of the size of our sun and the temperature is high enough for sustained fusion. In the star's constant internal battle of inwards gravity vs outwards expansion from fission, gravity is the current victor.

Then it makes it's one and only shot at being a star. A massive jet of gas shoots out from the protostar at this point, and if the mass already gathered isn't enough, the star will burn out in an anticlimactic fizzle, and become a brown dwarf, a glorified planet.

Here is a size comparison of the matter needed to form a star in comparison to just a large planet.

But if the mass is large enough, then the jet of gas will only clear away dust and leftover material that hasn't yet been sucked into the star, and it will be a stable main sequence star. The battle of gravity vs fission will be completely balanced at this point, with the star remaining stable in size and energy creation for billions of years.

The temperatures of stars range from 2500 Kelvin to about 50,000 Kelvin on the outside. Why so small you ask? Because different elements are being fused at different parts of the star based on their density and therefore their proximity to the center. But don't worry, it's still plenty hot at the compressed core, in fact the core is hotter than the protostar at around 15 million Kelvin, and this is just the sun I'm using as an example, and it's only a medium sized star.

So considering the intense amount of temperatures one would need to create stars, one can assume that Aurelion Sol is pretty hot.

Let's not forget of course, that he can crush stars. Since stars are usually super compressed already, this would lead to insane temperatures, since pressure generates heat.

In conclusion, whenever somebody asks you who the hottest LoL character is, you can say with absolute certainty, that it is Aurelion Sol. And if somebody asks you why, or calls you dumb for thinking that, you can hit them over the head with the facts.

This concludes this first episode, I plan on doing one every two weeks depending on my school schedule. If you have a League Question you'd like me to cover, drop it in the comments.

Thanks to MavenSong, FaceTheSun, and ZT Xperimentor for making this possible, thanks to HowStuffWorks for additional information, and thanks to RiotGames for making such an awesome champion.

See you next time.
