Is it HIS Tomb?

I don't know how many people in this class have looked into the so called discovery of Jesus Tomb, but I'm not sure about it. I mean they said their selves that the names Jesus, Mary, Joesph and so on were very popular names back then, so in a way the tomb could belong to anyone. Also I haven't studied the Bible like I should or looked into the Resurrection of Jesus Christ but, I don't recall hearing anything about what happened to his physical body after the three days. I mean did it just "disappeared" "vanish"?
