No human could survive the gravitational pressures, Martin Barstow, astronomer at England's Leicester University, was quoted as saying.
5.
Heating due to radioactivity, impact, and gravitational pressure melted parts of protoplanets as they grew toward being planets.

Again, gravitational pressure takes over and compresses the central core, increasing its density and temperature until the oxygen-burning process can start.

This increases the gravitational pressure on the core which is resisted by a gradual increase in the rate at which fusion occurs.

At the very center of the galaxy, the gas will condense so much under gravitational pressure that a supermassive black hole will form.
10.
All main sequence stars are in hydrostatic equilibrium, where outward thermal pressure from the hot core is balanced by the inward gravitational pressure from the overlying layers.
