Today on PTIB Jimmy DeYoung has a conversation with Dr Don DeYoung, head of the Science Department at Grace College in  Winona Lake, Indiana, and also an author who has written and lectured on Astronomy, the science that studies the "stars". Jimmy and Don will discuss the British Space Agency project of "mapping" our "Milky Way"; we'll find out how many stars, and galaxies, there are in outer space; and Don believes that there will be stars in the Tribulation Period that will fall on the Earth, Revelation 6 and go dark during that period of time, Revelation 8.
