The Cosmos is a rebellion against gravity. Gravity is a self-reinforcing force that can reduce all matter into a space less than an atom. Gravity is a self-imploding force that gets stronger as the size gets smaller. At an atomic level, Pauli’s exclusion principle precludes atoms from getting too close. When stellar furnaces go quiet, and gravitation overtakes the centripetal forces, the exclusion principle barriers further gravitational collapse.
The mass governs the hard stop.
The gravitational force happens to be the off shoot of the mass.
When larger stars run out of fuel and go supernova, the residual mass exceeds the repulsive forces of Pauli’s exclusion principle at the electron level. Atoms draw down their last defense at neutron level and settle into hugely potent, and incredibly dense neutron stars.
Still larger stars, at the end of their lifecycle, submit to gravitation, where Pauli’s exclusion principle is humbled at the neutron level. The neutrons can’t repel neutrons. Instead, they succumb to mutual obliteration and agree to exist only as a matter-less gravitational point, aka Black Hole.
Black Holes anchor galaxies and swing stars around them. So much for seeking enlightenment, when sheer darkness swings around distant points of light.
Our medium-sized star, our Sun, takes a leisurely 250 million years to make an orbit around the Black Hole that anchors our Milky Way. The Dinosaurs are still aboard the last ride.
The fission that lights the stars eventually exhausts its fires. The centrifugal forces, after a stubborn resistance to yield, fall prey to the almighty gravity. A White dwarf, a neutron star, or a Black Hole, Gravity claims them all.
The elephant in the room still begs an answer, why did Big Bang have to reverse the gravitational powers and re-engineer the Cosmos.
We are glad that the question exists, and we exist with it.
Yet, the immense, inexhaustible power of gravity that keeps satellites afloat, lunar orbit in a predictable trajectory, planets predictably around the Sun and Sun around the anchoring Black Hole taunt us as a source of energy all around us, and we not able to solve the riddle. The turbines around Earth’s orbit will never experience dearth of water for their rotational force.
Forget about Mars.
Let’s capitalize the Earth.
