i've yet to see anything in the UI that shows the "ladder" so to speak. i know of about 3 people that have reached level 3 and if you choose me as the right answer, i'll be closer :-) at this time, i don't think there's anyone at 4 or 5 given the daily limits.
How can I find a list of the top-rated people on Yahoo! Answers?

King Arthur really existed, but when you read the story, you will see it's a legend, so some parts changed. The point is he really existed.
Did King Arthur really exsist?

The source of Gamma Ray bursts is currently unknown. They are a surprising phenomenon because gamma rays are so powerful that very few events could cause them. They have also only been recently discovered by projects like the Compton Gamma Ray Observatory, and appear to be coming from all directions, not just in the galactic plane.
This would indicate a phenomenon that has extra-galactic origins... for example, activity inside of an active galactic nuclei, or quasars.
Because they happen at random intervals, abd are ephemeral (often just a few seconds), and the "scopes" used to capture them are not tightly directional, we don't have any instruments currently that can figure out exactly what they are. For now that means, the best we can do is hypothesize based on what cosmic events we believe are of the appropriate magnitude to tigger gamma rays.
what are gamma ray bursts?
