单词 gravitational collapse
例句 gravitational collapse

As the gravitational collapse continued, the primordial galaxies spun increasingly faster, because of the conservation of angular momentum. Cosmos 1980-01-01T00:00:00Z
In other words, the singularities produced by gravitational collapse occur only in places, like black holes, where they are decently hidden from outside view by an event horizon. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z
The existence of radiation from black holes seems to imply that gravitational collapse is not as final and irreversible as we once thought. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z
According to this scenario, some 4.5 billion years ago, the original body grew massive enough that the heat from its gravitational collapse and radioactive elements partially melted the rocks, which separated into layers. NASA launches spacecraft to a mysterious metal-rich asteroid 2023-10-13T04:00:00Z
This could mean that the parallel fields from less dense regions feed material into denser ones, where fields are strong enough to limit gravitational collapse despite the additional star-forming material, the researchers say. How Magnetic Fields Control Galactic Growth 2023-04-29T04:00:00Z
The pressure of the hot, ionized gas surrounding these stars compresses the material in the nearby edge of the molecular cloud and initiates the gravitational collapse that will lead to the formation of more stars. Astronomy 2016-10-13T00:00:00Z
In this theory, scientists hypothesize that a planet like Jupiter forms when part of a circumstellar disk becomes dense and cool enough to be vulnerable to gravitational collapse. Hubble discovers a Jupiter-like planet forming in a very strange way 2022-04-04T04:00:00Z
The smallest, like 'the Unicorn,' are so-called stellar mass black holes formed by the gravitational collapse of a single star. A black hole dubbed 'the Unicorn' may be galaxy's smallest one 2021-04-22T04:00:00Z
Sun-like stars fuse hydrogen into helium in their cores, producing copious amounts of energy that they use to support themselves against gravitational collapse. Planet discovered transiting a dead star 2020-09-15T04:00:00Z

These showed that generic gravitational collapse would lead to singularities — infinities that signal the need for new physics. Stephen Hawking (1942–2018) 2018-03-13T04:00:00Z
Theoretical predictions suggest an almost instantaneous gravitational collapse into a black hole is most likely. New frontier for science as astronomers witness neutron stars colliding 2017-10-16T04:00:00Z
In some of these theories, black holes never form, because gravitational collapse stops before the stellar remnants cross the point of no return. How to hunt for a black hole with a telescope the size of Earth 2017-03-21T04:00:00Z
What mechanism can oppose this gravitational collapse for a star? Astronomy 2016-10-13T00:00:00Z

When a black hole is created by gravitational collapse, it rapidly settles down to a stationary state, which is characterized by only three parameters: the mass, the angular momentum, and the electric charge. Stephen Hawking’s Reith lecture: Annotated transcript - BBC News 2016-01-26T05:00:00Z
Schwarzschild’s 1916 paper assumed a fluid sphere which, upon gravitational collapse, would halt contraction before complete collapse as it is understood by astrophysicists today. Hawking's Views On Black Holes Continue To Evolve 2014-01-25T19:24:00Z
