Question

In movies, there are explosions in space with fire and smoke but there is no oxygen in space. What is wrong? What would really happen ?

Answer 1

For an explosion with fire to occur, there must be a combustion of oxygen, and there is no oxygen in space, so that would be the mistake.

So it is NOT possible to say that in space there can be explosions. And what really happened would be the non-existence of this phenomenon in that place.
