that's physics looking impossible but actually existing and turning out to be possible

It's gravity keeping these cloud puffs together without it flying into space or falling apart, so it hovers but is stuck in an oblate spheroid and never falls apart. low density also causes material to puff up instead of being crushed down by the core and it lets it float a bit more,, if not a lot, keeping It gravitationally bound but not crumpled.

great old physics looking impossible yet possible
