"Atmospera" is a two-for-one deal. First, it's the science-y thing that keeps us from floating into space. But more importantly, it's the *vibe*. When your friend's house is awkward during a family fight, "ang bigat ng atmospera." When you're at a concert and everyone's singing along, "ang ganda ng atmospera." It's the invisible feeling in a room that tells you whether to have fun or to slowly back away.
