eli5: Why is it temperatures can go up to the trillions but only down to -273?
In: Physics
This is a weird question to answer because there really is no solid answer: “Why can most things in our daily life get A LOT hotter, but not a lot colder?” Well, that’s just the reality we exist in.
Technically, bonds that hold molecules together (and thus you and I together) can’t exist at very high temperatures. Therefore, anywhere there is life, things would have to be quite “cold” on the universal scale (much cooler than millions of degrees).
In general, most of space is “cold” (much closer to -273 than millions of degrees Celsius) and earth sits in the middle of empty space this earth is relatively “cold” to. So, since we humans were born on a planet much closer to -273 to millions of degrees, we acclimated to temperatures around that level and designed our systems that way. That’s about it.
