In the Dust of This Planet: Horror of Philosophy

Gregory says, 'Near to the Sun, the temperature was very high, so minerals and metals formed. And on the edge of the disc, far away from the heat of the Sun, less volatile solids like ice and ammonia formed. Approximately 4.5 billion years ago a dark cloud of gas and dust began to collapse. As it shrank, the cloud flattened into a swirling disk known as a solar nebula, according to NASA Science.

The Exploit: A Theory of Networks, co-authored with Alexander R. Galloway. University of Minnesota Press, 2007. ISBN 978-0816650446.Moons of solid Solar System bodies have been created by both collisions and capture. Mars's two small moons, Deimos and Phobos, are thought to be captured asteroids. [90] If the reader is already vaguely familiar with horror literature and the history of philosophy, then this book shouldn’t pose too much of a challenge. If, however, one is completely uninterested in the connections between philosophy, horror, and mystical theology, then this book will probably not engage your interest at all. Yet, even if you are incredibly engaged and interested in this topic, you might still be disappointed by the repetitiveness of his analysis in this volume. The Solar System is chaotic over million- and billion-year timescales, [99] with the orbits of the planets open to long-term variations. One notable example of this chaos is the Neptune–Pluto system, which lies in a 3:2 orbital resonance. Although the resonance itself will remain stable, it becomes impossible to predict the position of Pluto with any degree of accuracy more than 10–20million years (the Lyapunov time) into the future. [100] Another example is Earth's axial tilt, which, due to friction raised within Earth's mantle by tidal interactions with the Moon ( see below), is incomputable from some point between 1.5 and 4.5 billion years from now. [101] Moons have come to exist around most planets and many other Solar System bodies. These natural satellites originated by one of three possible mechanisms:

But that restrictive definition helped isolate what should and should not be considered a planet — a problem that arose as astronomers discovered more and more planet-like objects in the solar system. Pluto was among the bodies that didn't make the cut and was re-classified as a dwarf planet.

Neptune is approximately the same size as Uranus and is known for its supersonic strong winds. The planet is more than 30 times as far from the sun as Earth. Around 5.4billion years from now, the core of the Sun will become hot enough to trigger hydrogen fusion in its surrounding shell. [115] This will cause the outer layers of the star to expand greatly, and the star will enter a phase of its life in which it is called a red giant. [118] [119] Within 7.5billion years, the Sun will have expanded to a radius of 1.2AU (180 × 10

Gravitational collapse

The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud, [9] most likely at the edge of a Wolf-Rayet bubble. [10] The cloud was about 20 parsecs (65 light years) across, [9] while the fragments were roughly 1parsec (three and a quarter light-years) across. [11] The further collapse of the fragments led to the formation of dense cores 0.01–0.1parsec (2,000–20,000 AU) in size. [a] [9] [12] One of these collapsing fragments (known as the presolar nebula) formed what became the Solar System. [13] The composition of this region with a mass just over that of the Sun ( M ☉) was about the same as that of the Sun today, with hydrogen, along with helium and trace amounts of lithium produced by Big Bang nucleosynthesis, forming about 98% of its mass. The remaining 2% of the mass consisted of heavier elements that were created by nucleosynthesis in earlier generations of stars. [14] Late in the life of these stars, they ejected heavier elements into the interstellar medium. [15] Some scientists have given the name Coatlicue to a hypothetical star that went supernova and created the presolar nebula.

Formation of the Solar System after gas and dust accretion to a protoplanetary disk. The vast majority of this material was created from the primal supernova The evolution of moon systems is driven by tidal forces. A moon will raise a tidal bulge in the object it orbits (the primary) due to the differential gravitational force across diameter of the primary. If a moon is revolving in the same direction as the planet's rotation and the planet is rotating faster than the orbital period of the moon, the bulge will constantly be pulled ahead of the moon. In this situation, angular momentum is transferred from the rotation of the primary to the revolution of the satellite. The moon gains energy and gradually spirals outward, while the primary rotates more slowly over time. And on the cool edges, the gas and ice giants were born: Saturn, Jupiter, Neptune, and Uranus. The asteroid belt Gravitational disruption from the outer planets' migration would have sent large numbers of asteroids into the inner Solar System, severely depleting the original belt until it reached today's extremely low mass. [56] This event may have triggered the Late Heavy Bombardment that is hypothesised to have occurred approximately 4billion years ago, 500–600million years after the formation of the Solar System. [2] [75] However, a recent re-appraisal of the cosmo-chemical constraints indicates that there was likely no late spike (“terminal cataclysm”) in the bombardment rate. [76] Pessimism, Futility, and Extinction" Theory, Culture & Society interview with Thomas Dekeyser (17 March 2020).The Solar System has evolved considerably since its initial formation. Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later to have been captured by their planets. Still others, such as Earth's Moon, may be the result of giant collisions. Collisions between bodies have occurred continually up to the present day and have been central to the evolution of the Solar System. Beyond Neptune, many sub-planet sized objects formed. Several thousand trans-Neptunian objects have been observed. Unlike the planets, these trans-Neptunian objects mostly move on eccentric orbits, inclined to the plane of the planets. The positions of the planets might have shifted due to gravitational interactions. [2] Planetary migration may have been responsible for much of the Solar System's early evolution.
