How Much time if any elapsed between Genesis 1 v1 and Genesis 1 v3?

See: The Gap Theory This theory holds that the gap in time between God's initial creation in Genesis 1:1 and His subsequent re-creation (The Seven Days of Creation) is when Satan rebelled against God. Notice 1:1 says God created the heavens and the earth. 1:2 says" the earth was void and darkness ruled over the face of the deep" showing something chaotic happened. The time frame here could be billions of years, which can account for the old age of the earth and universe. The book "Earth's Earliest Ages" By G.H. Pember details this theory and the time gap between Genesis 1:1 and 1:3 very well.
