No, but it can exist as that form at the same time in a relatively short area and time!
I'll defer to the physics and chemistry experts as to that. In any case, if true, it only exists as a possible analogy, rather than proof of the existence of a trinity, or even of a higher power.
I think the whole thing was settled by the guys with the biggest swords a long time ago, but that's just my skeptical atheist nature coming out.
