Penetrate.

"Our only remaining hope and salvation,” Bacon wrote, “is to begin the whole labor of the mind again, not leaving it to itself but directing it perpetually from the very first.” A century later, William Herschel agreed. Herschel, the first man to understand that telescopes penetrate time as well as space, spent the long daylight hours polishing his lenses, listening to his sister read from Don Quixote and the Thousand and One Nights. When darkness fell, his lenses clear, he discovered a heretofore unknown planet.
