Fire is not anti-gravity, but it can appear that way in certain situations because of how it behaves.
Why fire seems to rise (but isn’t anti-gravity):
When something burns, it heats the surrounding air.
Hot air is less dense than cold air, so it rises due to buoyancy—just like a hot air balloon.
As the hot air rises, it pulls the flame upward with it, giving the illusion that fire is “defying gravity.”
This rising motion is not because fire resists gravity, but because of how hot gases interact with gravity.
In zero gravity (like on the space station):
Flames look round and blue because there’s no "up" for hot air to rise.
Without gravity to move hot air upward, convection stops, and fire behaves very differently.
So, fire relies on gravity for its familiar shape—it’s not anti-gravity at all.
