Multiple times Elizabeth Hopkins says that she is an employee of "Lloyds of London" and that her "company insured" an item of jewelry. Contrary to popular misconception Lloyds of London is an underwriter, or market, of insurance policies but does not actually insure anything.
Larry Fleinhardt says he had a special interest in a star he calls M170. He says one time he looked for the star, it wasn't there anymore, having "died 2.2 million light-years ago". Unless he was using a powerful telescope (which he didn't mention), it's not possible to see an individual star 2.2 million light-years away. The most distant stars visible to the naked eye are less than 7000 light-years away.
Larry uses "light year" to describe a long period of time, when it is actually the DISTANCE light travels in one year, about six trillion miles. It has nothing to do with time, it would be like saying someone will be twenty miles old on his next birthday.
Larry talks to Charlie about a star that had been dead for 2.2 million light-years. A light-year is a unit of distance, not a unit of time. There is no way that an astrophysicist would make a mistake like this.
