A surprisingly good question.
Multiple good ones, in fact, including:
- what does it contain?
- what is is that we see?
- how much does fire vary based on what it contains?
- why can the thing we see be so big?
- Is a lot of fuel being propelled while oxidation is relatively slow?
- is there energy exciting electrons and causing sort-of-secondary light?
- Is plasma involved or not?
