Universal translator. The holy grail of simultaneous interspecies translation directly
matched brain-wave frequencies
with similar meanings across galaxies and cultures, providing
Star Trek characters
(and the viewers at home, who
evidently had universal translators as well) the ability to “hear” English spoken by aliens.
