Did You Know?


When the universal translators malfunction and cause everyone to start speaking different languages Burnham calls Saru to the bridge, when he arrives Captain Pike says "welcome to the Tower of Babel Mr. Saru". Pike is referring to a story from the Bible about human's first attempt to congregate in one place and build a large city with a huge tower, contrary to God's commandment that humans spread out, multiply and fill the Earth. When the humans living in Babel failed to heed the warnings and continued to build the tower legend has it that God caused them all to speak different languages, with their ability to understand each other gone the tower went unfinished and the people spread out into groups that spoke the same language.

When the Universal Translator goes offline, the crew are speaking in different languages. You can see their mouths moving properly with the language they are speaking. Everyone's lips should have been moving to their native language as we hear a different language. This is an error that has occurred throughout Star Trek shows and movies except Star Trek: Beyond where the alien that directed the Enterprise to the planet spoke in her native language but the translator in her collar translated for her.

Captain Christopher Pike: That damn holographic comm system. Tell Louvier to rip out the entire system. From now on, we'll communicate using good old-fashioned view screens. Truth is, I never liked the holograms. They look too much like ghosts.
Number One: [amused] Hm.
Captain Christopher Pike: He told you I'd say that.
Number One: No. I told him.
