Nowhere do we find the complete sequence." Q&A: This episode's question is a bit of a spoiler, so if you haven't seen the movie "Prometheus" and you don't want to know anything about it, even though this is covered in the trailer, skip forward about two minutes.The question comes from Coffee who asked me to weigh in on some discussion he had read about some of the astronomy in the movie "Prometheus." Among the points raised was: "Can you really tell where a unique star system is based on five dots in a cave painting?

Download the Episode Recap: An overview discussion of craters and how they are used to date surfaces in the solar system as well as some of the caveats, complications, and limitations that go with the method.
Puzzler: If a 1-km-diameter comet hits the moon, and a 1-km-diameter asteroid hits the moon, is the crater created by the asteroid likely to be larger, the same size, or smaller than the one created by the comet. Solution to Episode 39's Puzzler: The answer is pretty much a "Yes." There are a few areas on Earth where we have some very complete geologic columns, going from present time back to the precambrian or older.
This is contrary to what many creationists claim, such as the quote from Morris and Parker (1987), "Now, the geologic column is an idea, not an actual series of rock layers.
If I say that Earth is approximately 4.54 billion years old, even though I put that "approximately" in there, that's an absolute age.
A relative age is when we don't have a number assigned, but we know that something is older or younger than something else.
For example, my brother was born after I, so I'm older than he is.
The first is that you can designate any random pattern of five points and then find innumerable matches in stars in the sky, especially if you go to stars not visible to the unaided eye.
So uniquely specifying a system based on this is wrong. You can't get any depth information out of it which makes the number of matches go up even more.
