The standard model assumes that the life spans of stars run mutually exclusive of objects similar to Earth, Jupiter, Venus, Neptune, etc. In the standard model it is impossible for the Sun to be a baby planet.

In the standard model a star keeps its mass forever, even though it radiates in very, very large amounts over hundreds of millions of years, thus meaning the standard model contradicts the mass-energy equivalence principle. In the standard model stars are big and heavy and planets are small and lightweight.
