The show mentions that the artifact is pointing to a specific star but this cannot be as the earth rotates and the artifact never points at the same location in the sky.
The artifact is described as being encoded in Binary in some episodes but contradictorily describes it as hexadecimal in other episodes (hexadecimal for the word white 77 68 69 74 65, the binary for word white is 01110111 01101000 01101001 01110100 01100101)
Dark matter is not visible, so it would not look like dark clouds.
In exterior shots of the ship, it is incorrectly depicted making the droning sound of a jet or rocket lumbering by. In the vacuum of space, the ship would pass by silently. This is an error in virtually every space flick ever made with the exception of 2001: A Space Odyssey.
