The model may also account for dark matter and dark energy, resolving multiple problems at once. Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity. “The Big Bang singularity is the most serious problem of general relativity because the Read More ›
