Indeed, arbitary. Just like the fall of Barad Dur upon the destruction of the One Ring was arbitrary and nonsen...oh wait.
Yep. Sci-fi and fantasy are totally the same thing.
Magic! In space!
For things like this we have the
Mohs Scale of Sci-fi Hardness. It ranges from 1 to 6, where 1 is "space magic" and 6 is real-life science.
The Crucible as described in the Codex entry is a giant directed energy weapon. It converts a vast amount of helium-3 into energy and then proceeds to fire it through the Mass Relay system. How it manages to hit a Reaper without just killing everything in its path isn't explained.
My theory for Control is based off of the "rewrite the heritics" option from Legion's LM. The Crucible uses the massive fusion reaction that powers it to transmit an updated control signal to the Reaper fleet across the Relay network. Shepard becomes the new guiding intelligence of the Reapers. He's still Shepard, but he has the ability to see the universe from their perspective. Think a mix of ascended Daniel Jackson and JC Denton in
Deus Ex: Invisible War. With Synthesis I sort of work off of the assumption that the Reapers are largely nanotech-based. Indoctrination, the Husk creation process, and the Reaper reproduction process are based around converting organic material into synthetic components. Synthesis would involve the Reapers being given the command to dissassemble themselves down to the nanites that they are constructed from.
From there the Crucible is configured to fire an EM pulse that allows the nanites to be sent across the Relay network they then proceed to integrate themselves into organic lifeforms. The end result is similar to Deus Ex's concept of
Nanotech Augmentation. As for the whole "rewriting DNA" thing,
nano-scale machines made out of DNA exist in the real world, right now they're really simple mechanisims but more sophisticated machines could be possible in the future. It might be possible to introduce genetic sequences that allow the body to assemble DNA-based nanomachines on it's own (e.g. "A new DNA") but I highly doubt that's what Mac and Casey were getting at.
