What is the concept behind the Firestorm used by Professor Stein and Ronnie/Jax; i.e. how does the Firestorm work? And how do they merge with each other?

It would be helpful if someone could explain the concept deeply.

Thanks to those giving time to this question.

  • What do you mean by concept? Do you mean the in-universe explanation? If so, can you edit your question to something like how is the "merging" of Firestorm explained in-universe? Commented Mar 15, 2017 at 9:47
  • I mean that how it works

    It'll be quantum something....I just know it will.

    @SagarMishra - the answer is most likely technobabble, so the specifics usually are not terribly important or noteworthy. I know in the original comic series for Firestorm the same mechanic was used, and they seemed to understand it just as little then, to the point they had to work to figure out that a 3rd person was involved in the merging. That said, the question can hang out until someone else posts an answer, it just may not be immediately.

Paulie_D called it. Quantum Splicing.

As Caitlin explains it to Stein:

A quantum splicer, a fission device designed to bombard your atoms with as much energy as they experience inside the particle accelerator explosion. - Flash S1E13

This device basically can cause or reverse the results of the particle accelerator explosion which happened to Stein and Raymond, allowing them to merge and separate as needed.

We see many different abilities that people receive from the particle accelerator explosion, some of them are circumstantial or environmental (Weather Wizard gets power over weather because he was in a storm at the time). Presumably because Raymond was in the accelerator, his atoms got scattered, and then found a compatible host with Stein to create the entity Firestorm.

If you are asking for a scientific explanation, this is science fiction, please check your science at the door.

    Of course it was quantum. We all know quantum is basically magic, right?

  • So it's really a quantum leap?
