Cosmology and the Origin of Life
Starting the Thermal Countdown: From the weird to the semi-understandable:
At very early times:
At this time Gravity and the Strong Force have the same magnitude. That is:
At this time Gravity and the Strong force now have separated but the Weak force and the Electrostatic Force still have the same magnitude.
When these forces are decoupled the Universe is said to go through a phase transition. The symmetry is broken in a specific manner so that the forces have now separated and are defined by a characteristic ratio of their strengths. This defines the physics of our Universe.
