Made you laugh? Great!
Made you think? Even better!
Made you rage post? Get therapy.

Fillik: The pressure gauge is spiking. …and now it’s on fire?
Osha: On it!
Fillik: Wait. You need fuel, heat and oxygen for a fire. There’s not enough oxygen and heat in outer…
Osha: *interrupts with a wave of her hand*
Osha: This is not the high school physics you were taught.
Fillik: *stares blankly* This is not the high school physics I was taught.

Space is actually not "cold". If heat is added, it is very slow to escape. The void is technically not a low temperature, it's just the ultimate insulator.

So the heat will be essentially what it is inside the ship, because it would take hours for the gas to get any colder.

As for oxygen, the ship is full of it. We can tell this by the fact that the people inside of it are not suffocating.

So if a fuel line and an oxygen line rupture at the same time. you get fire. The fire wouldn't look exactly like that, due to microgravity, but there WOULD be fire.

People added context they thought you should know:

Heat is the measurement of the motion of particles.

Space is a vacuum, an area with no particles.

Space is, by definition, cold.

https://en.wikipedia.org/wiki/Temperature

https://en.wikipedia.org/wiki/Vacuum

https://en.wikipedia.org/wiki/Outer_space

If the particles aren't there, it doesn't make sense to describe them as having low movement.

Is Antarctica heavily opposed to Katy Perry? Well, we conducted a poll there, and nobody rated her as "good" or "very good". Therefore, Antarctica is heavily opposed to Katy Perry.

Readers added context they thought you should know:

If there are no particles in a space, the total motion of the particles is zero, which is, in fact, a low number.

https://en.wikipedia.org/wiki/Number

Motion is a vector. Absence of particles is not absence of heat. If I pump the air out of a room, we wouldn't say I've made the room colder, I've just reduced the total number of particles in it. In fact, by your reasoning, we would have to say that the inside of an oven when it is going at maximim power is COLDER than, say, 100 square KM of alaskan tundra. There are more particles overall, even if the heat per particle is lower, so there is more TOTAL thermal energy, right? Temperature only makes sense as a measurement of energy PER particle, otherwise large things are always going to be "hotter" than small things by virtue of the fact that they have more particles! Space actually does have SOME particles, it's not a total vacuum, and some of thsoe particles are moving at extremely high speed, emitted from stars. Your odds of hitting one are low, at least over a short distance, but they do exist and they do have energy. Energy PER PARTICLE is what counts, not total particle energy.

Readers added context they thought you should know:

The way that temperature is generally measured is average particle motion per area. The inside of an oven, if you took the average temperature of all of it, would be higher than the average temperature of Alaskan tundra.

If there is zero particle motion in a given area (i.e. Space), then even if you take into account the few stray particles, the average temperature will still be nearly zero.

Space is three-dimensional, why are we talking about "area"?

Secondly, the Average as mathematical concept exists SPECIFICALLY TO AVOID POPULATION BEING A FACTOR.

If there's one particle in the volume, but it has high energy, then the average energy of the particles in that volume is quite high!

Your definition again doesn'tr work, because if it did, denser objects would always count as being "hotter" than less-dense objects. A big, warm summer stormcloud in tropical weather, vs handheld lead sphere at room temperature.

Which is warmer? The stormcloud, but if you measure by area, you'll get more total energy from the lead ball, because it has more density.

The only sensible metric is average energy per particle. And by that metric, SPACE IS NOT COLD.

Readers added context they thought you should know:

Firstly, spacetime is four-dimensional.

Secondly, average energy per particle would not work as a metric, because if a hypothetical place existed with several thousand cold particles and one very, very warm particle, that would make the mean temperature higher than it should be.

https://en.wikipedia.org/wiki/Mode_(statistics)

that would make the mean temperature higher than it should be

For a very brief time, yes, that's how physics works! That particle would eventually, via collisions with other particles, diffuse it's energy. This is thermodynamics! You can't just ignore small amounts of high-energy matter, if you could, radiators wouldn't be able to heat up a room!

Readers added context they thought you should know:

If you were to pick a random point in all of space, that point would almost certainly not have a particle in it, and therefore have zero energy.

Thank you @community-notes-official and everyone who got me to 100 reblogs!

(Of all the things to hit this milestone! 😂)

100 posts!

Wow. Don’t know how to feel about this. Not that I could be posting too much. Not that don’t have an audience (I don’t. I post for me). …but that the post in question is a rant about being fully disappointed in a tv series I was looking forward to watching.

Whatever. :) I’m over it.
