I HAVE refered you to sources, Josep. Try buying a copy of the latest "Astronomy" magazine off of any well-stocked magazine stand. Or "Scientific American." Or "Science News," a weekly magazine. Do an internet search for any one or all of these magazines and read some sample articles.

RECENT sources, Josep. Ten years is a fairly long time in a fast developing field in which new information is coming in every day.

You want ME to spend MY time cutting-and-pasting articles for you to read? Educate yourself and try to keep up!

Do your own damned homework, Josep!
