Freeze-ray. It's good that it didn't work.
Stopping time isn't all it's cracked up to be. You stop time. That stops everything. Nothing moves; nothing breathes; nothing thinks; no lights shine; no heat eminates; no masses attract; nothing happens.
Sure, you could make it so only you, yourself, don't stop in time, but have fun suffocating and being crushed to death in the cold dark, as you could no longer move in the atmosphere that has now effectively turned solid at what would act like 0 degrees Kelvin, flash-freezing your body, and not to mention that your mass would continue to try to move forward for that one instant when time stopped the world rotating, which would shatter your body instantly in a confined space with only the oxygen left in your lungs to allow the pieces to fly about in 0-G for the instant before it is also frozen. Either that or the effective mass of the entire universe would become 0 and the absolute vaccuum would instantly rip you (and every atom of you) apart regardess of the flash-freeze.
As for the rest of us, would we just see someone die, instantly atomized, and our own time continue onward or would all of existence end? The idea of stopping time means stopping time relative to a time that continues on, which contradicts the concept of stopping time. So… you can't really stop time without stopping all existence.
Now what about stopping time for one object relative to real time? We're back into the "0-degrees Kelvin, not moving with the rest of the Universe" problem. It would be like a slow-motion nuclear explosion as the 0-degrees mass is forcibly driven into the ground or nearby object, shattering everything that passes by it, or flash-freeze everything nearby (including atmosphere), dragging everything with it, as it appears to be launched into space. Either that, or it would reduce the effective mass to 0, and the object would appear to simply blink out of our own existence with an enourmous thunder-clap as the air instantly collapses into the previously-occupied space with a force felt never before on this planet.
Bad idea. Really bad idea.
Or did I think way too much on this and should have left it with "he threw a car at my head"?
