Is also "seem to be like a time machine" a correct expression? How's it difference from "seems like a time machine"?

While "seems to be like a time machine" does work technically, it sounds a bit awkward due to the "to be like" part. The speaker has made a general guess about the machine, so "to be like" is unnecessary here. Some more natural ways of expressing this would be "seems like some kind of/type of time machine," or "seems like a time machine" as stated in the video.
