Well, I have had a debate with some guys on a facebook group about whether there are many suns in the Universe. I think we have only one sun. That is "The sun". The star which is the closest to the Earth. However,all of them are saying that the name of the sun is "sol" and there are many suns in the universe. It's a general term for stars. I don't think this is true. The Cambridge Advanced learners dictionary 3 defines sun as:the star that the Earth moves around, which provides light and heat for the Earth, or the light or heat that the Earth receives from this star . The wikipedia defined sun as the star at the center of the Solar System. So who is right? Me or them?
