You know guys, the planets is composed mainly of two types of rock material, Fe-material( siderolites) and the stony element (aerolites), these are heavy elements and available in the apace, which formed planets and stars within 1-2 billion years just because there were two Big Bangs, one exploded 15 billion years ago and final burst occurred 14 billion years ago. These explosions carried different potencies, the first one had some material of light type and the second and final explosion produced the heavy material and this is the reason the aerolites and siderolites which are both light and heavy elements are very much available in the universe. These aspects disqualify the single BB theory and support the Two Big Bang Theory under TOPU. Ibid pp.185 Two Big Bangs Created The Universe in Eternal Space: Dr. Raj Baldev The first generation of stars could be formed only between 1 and 2 billion years from the first and second explosions, which occurred 15 and 14 billion years ago with a margin of 50 million to 1 billion years.
