a time machine that only points backward, catching light older than your entire species.
means An optical instrument that gathers and magnifies distant light, letting you see faraway objects—stars, planets, ships—as if they were close.
from From Greek 'tele-' (far) and 'skopein' (to look at, to watch), so literally 'far-seer.' The word took shape in early 17th-century Italy, when the new far-seeing tubes appeared; it's often credited to a Greek scholar at the court who coined the elegant compound for Galileo's device. 'Skopein' is the same root hiding inside microscope, periscope, and that nosy word 'scope' itself.
