Setting the Universe on fire

Ye, I may miss few scientific details, but fire can't exist in the void of space.

I'm pretty sure such a feat would be 3-A, via destroying a universe, but I don't see any way to even calculate it, whether or not fiction ignore science.

Best way i can think of is increasing the heat of the entire universe into some high degree that is considered destructive in the comsic scale.
 
Most of the universe is empty space/dark matter and energy. Only 4.6% of the universe is matter. And then a large chunk of that is made of stars and neutron stars and black holes and things like that, things that you can't even set on fire, or are hotter than fire.

So even if this was calcable in any way, there's far less than 1% of the universe that can we can even say would be capable of burning. This probably wouldn't get past 4-B. Even if all trillions of stars went supernova, the total energy combined wouldn't even reach baseline 4-A.

I assumed something like this. Anyway I could calculate that? Or at least start the calc. Also note this isn’t destroying the universe.

Note that for something to be set on fire without an oxidizing agent, particularly oxygen. There's no presence of oxygen in outer space and there's nothing for said flames to burn, so realistically a fire cannot occur.

But if it did, then said fire would cover a universal-sized area of effect and it'd most likely be straight up universe level, if not higher because chances are, said fire would most likely disintegrate everything contained within said universe probably.

Wouldn't it have to be a lot hotter than regular fire? It'd have to burn neutron stars, quasars and the like, even if it were possible.

Probably, although the temperature of said fire is most likely indeterminable.

Solar flares can be seen as a jet/stream of fire protruding from the Sun in outer space though, so if a fire was said to engulf the entirety of the universe, said fire should at least be that hot.

Engulfing is one thing, being able to do anything to the universe as a whole is another.

And I'm not sure if those jets of plasma count but I'm no physicist.

Said jets of plasma do look like flames from a glance, so I'd thought I would just give it a mention.

The required energy for the entire fire to do anything to the universe would still be very likely beyond the minimum requirement for Universe level though, since it is practically impossible for an empty space of universal size that has no oxygen inside of it to even combust, much less continuously.
