WebApr 8, 2024 · In a black hole, most of what we know about reality simply falls apart. A planet or star has a radius, a size. A black hole doesn’t have a size. There is no size, no matter how small, that it could be because gravity would always crush it even smaller. Black holes are often called singularities for this reason. WebWell yes, and the best proof I can think of are the stars orbiting our galaxy's galactic center black hole, which is a supermassive black hole in the center of the Milky Way in the Sagittarius A* region: Inferred orbits of 6 stars around supermassive black hole candidate Sagittarius A* at the Milky Way galactic centre.

Thousands of Earthlike ‘blanets’ might circle the Milky Way’s …
WebThe basic idea is tidal forces. Given a body orbiting any mass, including a black hole, the nearer part will be attracted more strongly than the farther part. In Newtonian gravity (close enough for outside very large black holes), this amounts to a differential acceleration of G M d r 3, where M is the mass of the primary, d is the distance ... WebA stellar black hole (or stellar-mass black hole) is a black hole formed by the gravitational collapse of a star. [1] They have masses ranging from about 5 to several tens of solar masses. [2] The process is observed as a hypernova explosion [3] or as a gamma ray burst. [3] These black holes are also referred to as collapsars . open a free hushmail account

WebHello all. This question would break astrophysics because I know that a black hole feeds off of stars and no star can have these conditions. My question is assuming a star was either so big that it was equal mass and density to a black hole that an equilibrium is created or that somehow the star was made to where it was resistant to any of its own mass being … WebApr 7, 2024 · Just as a third star can displace one member of a binary system, when two black holes orbit each other the arrival of a third can slingshot the lightest of the three out of the system. The other ... WebFeb 4, 2024 · Surprisingly, the answer is a tentative yes, researchers say, although there are plenty of reasons why life could never take hold in such a place. If it did, living on such a planet would be truly surreal, with the black hole filling nearly half the sky and concentrating leftover photons from the big bang into a pseudosun. open a fortune cookie
