WebThe Sun has been shining for 4.6 billion years. Considerable hydrogen has been converted to helium in the core, where the burning is most rapid. The helium remains there, where it absorbs radiation more readily than hydrogen. This raises the central temperature and increases the brightness. Model calculations conclude that the Sun becomes 10 percent … WebThe mean time between major impacts is estimated to be at least 100 million years. During the last 540 million years, simulations demonstrated that such an impact rate is sufficient to cause five or six mass extinctions and 20 to 30 lower severity events. This matches the geologic record of significant extinctions during the Phanerozoic Eon.
