Gravitational collapse is the condensing of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of mass. Gravitational collapse is a fundamental mechanism for structure formation in the universe. Over time an initial relatively smooth distribution of matter will collapse to form pockets of higher density, typically creating a hierarchy of condensed structures such as clusters of galaxies, stellar groups, stars and planets.
A star is born through the gradual gravitational collapse of a cloud of interstellar matter. The compression caused by the collapse raises the temperature until thermonuclear fusion occurs at the center of the star, at which point the collapse gradually comes to a halt as the outward thermal pressure balances the gravitational forces. The star then exists in a state of dynamic equilibrium. Once all its energy sources are exhausted, a star will again collapse until it reaches a new equilibrium state.
"Gravitational collapse" is the inward fall of an astronomical object due to the influence of its own gravity which tends to draw the object toward its center of mass. Gravitational collapse is at the heart of structure formation in the universe. An initial smooth distribution of matter will eventually collapse and cause a hierarchy of structures, such as clusters of galaxies, stellar groups, stars and planets. A star is born through the gradual gravitational collapse of a cloud of interstellar matter. The compression caused by the collapse raises the temperature until nuclear fuel ignites in the center of the star and the collapse comes to a halt due to the outward thermal pressure balances the gravitational forces and the star is in dynamic equilibrium. And, when all its energy sou...
Different SPH systems are collapsed under their own gravity and collided with each other to emulate simple planetary formations and collisions (think gas collapsing and condensing to form planets and then those planets collide). The coloring is kept basic to make it easy to see which particles came from what body. This is from a currently entirely non optimized brute force C++ AMP WindowsRT component in a windows 8 store app, which I am working on, in my spare time, as a generalized SPH experimentation application. I suggest subscribing for further updates, if you think that sounds interesting. The main focus of this video is the different behavior when systems have opposing orbit and spin momentum and when they do not. It shows how the total angular momentum is less with opposing spi...

A basic SPH system collapsing under its own gravity to emulate simple planetary formation (think gas collapsing and condensing and forming a ball) Coloring is a basic "hot" colormap based on density. This is from a currently entirely non optimized brute force C++ AMP WindowsRT component in a windows 8 store app, which I am working on, in my spare time, as a generalized SPH experimentation application. I suggest subscribing for further updates, if you think that sounds interesting. The main focus of this video is the role of viscosity in stabilizing such a system and dampen out relative velocity. This, in the end, leads to rigid body rotation, even though the early system was very chaotic.
Collapse with excision: horizons.
Having stunned critics and fans alike with their acclaimed 2012 Prosthetic debut "Empyrean" — described as "a harrowing descent into the bleakest that black metal has to offer" (About.com) — MUTILATION RITES are ready to release their long-awaited follow-up. Once again recorded with Kevin Bernsten (TRIAC, Magrudergrind) at Developing Nations in Baltimore, the new album, "Harbinger," will be the band's first full-length to feature Ryan Jones (ex-Today is the Day) on bass and vocals. Pitchfork.com accurately describes MUTILATION RITES in the following manner, “Think of late-period Darkthrone vomiting the youthful version of themselves onto the crowd at a filthy DIY space. It's stately and epic, but booze-soaked, filthy, and feral.” http://store.prostheticrecords.com/bands/mutilation-rites
