I've looked on wikipedia and google, and all I'm getting is techno-babble. Maybe you smart people can answer my questions instead? 1: How many different types of stars are there, and what are their features/names? 2: What is the maximum speed achievable in space at this time? 3: What kind of power does a supernova have? Could it destroy a solar system, a variety of solar systems, a sizable portion of the galaxy etc 4: What kind of power does a regular nova have?
