The big bang theory states that all the matter that makes the universe was, at the beginning, I in a single infinitesimally small and infinitesimally dense point. Then, the point explodes given birth to the universe that we know. One of the major foundations that the universe was originated in that explosion called the big bang was made by Hubble when he proved that the universe is expanding; therefore, generally speaking galaxies are moving away from earth. The occurrence that contradicts the big bang theory is: A “Over time, distant galaxies move progressively closer to Earth
Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.
