the.com/apogee

the moment something stops climbing and the only direction left is down.

means The highest or most distant point of something — literally the point in an orbit farthest from Earth, and figuratively the peak of achievement or intensity.

from From Greek 'apogaion,' a blend of 'apo' (away from) and 'gaia' (Earth) — literally 'away from the Earth.' Greek astronomers used it for the point in the Moon's orbit where it swings farthest from us. It traveled through Latin into English as a stargazer's term in the late 1500s, and from there drifted skyward into metaphor: the farthest, highest reach of anything.
