are all black holes spinning?

As all known stars rotate and realistic collisions have non-zero angular momentum, it is expected that all black holes in nature are rotating black holes. ... A black hole in the Milky Way, GRS 1915+105, may rotate 1,150 times per second, approaching the theoretical upper limit.

Astronomers found gargantuan black hole 40 billion times bigger than the Sun — and it's still not the biggest black hole ever. A black hole 700 million light-years from Earth has a mass 40 billion times that of our Sun.

X-rays don't escape from _inside_ the black hole, but rather come from hot material right _next to_ the black hole. Once that hot material goes inside the black hole, no X-rays or anything else ever come out again. ... The X-rays are coming from the disk of material around the black hole.

When you do that search, Google listens and make the search results page do a barrel roll. ... The 'do a barrel roll' query, which causes the search page to spin, will remain in place for a while. This is the latest of several Google search easter eggs. You can search for “tilt” or “askew” and see another one.

Black holes don't suck. 1. Every star you see in the night sky is bigger and brighter than our sun. Of the 5,000 or so stars brighter than magnitude 6, only a handful of very faint stars are approximately the same size and brightness of our sun and the rest are all bigger and brighter.

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death. ... Black Holes 101 At the center of our galaxy, a supermassive black hole churns.

Will CERN generate a black hole? The LHC will not generate black holes in the cosmological sense. However, some theories suggest that the formation of tiny 'quantum' black holes may be possible.

No such micro black hole has been observed at CERN. In September 2010, a signal that is closely related to black hole Hawking radiation (see Analog models of gravity) was claimed to have been observed in a laboratory experiment involving optical light pulses. However, the results remain unverified and debatable.

No, not all stars are in a galaxy. They may have once belonged to a galaxy, but they are not a part of it any more. Some of these so-called "stellar outcasts" or "intergalactic stars" have actually been observed by NASA's Hubble Space Telescope. ... We can observe their motion, and the motion of any nearby galaxies.

They do not. They do not. There is an inverse correlation between a black hole's mass and its volume, so the more massive a black hole gets, the lower its average density becomes.

Black Holes Are 'Portals to Other Universes,' According to New Quantum Results. According to Albert Einstein's theory of general relativity, black holes are uninhabitable chasms of spacetime that end in a "singularity," or a mass of infinite density.

And because black holes form from the deaths of supermassive stars (i.e., normal, baryonic matter), the initial composition of a newly-formed black hole is always approximately 100% normal matter and 0% dark matter.

Supermassive Black Hole. As the name suggests, supermassive black holes contain between a million and a billion times more mass than a typical stellar black hole. ... From these observations, astronomers have inferred that a supermassive black hole of about 3 million solar masses lurks at the centre of our galaxy.

Neutron stars are city-size stellar objects with a mass about 1.4 times that of the sun. If the mass of the star collapsing is much more then it would form a black hole. ... Large black holes have a density less than that of a neutron star. So they do not need to contain a singularity (only e.g., neutron stars).

The only reason why a black hole does not work with the theory is that it's gravity is greater than the speed of visible light. Thus the speed of gamma waves must be faster than the speed of visible light. If you look at the electromagnet spectrum. Gamma waves are at a much higher frequency than visible light.

Black-holes count as ordinary matter (made from 16 particles of standard model). As you know, ordinary matter and energy can be converted to each other (they are actually the same thing) and they make about 4.9% of the known universe.

Does age really depends on gravity and time paradox? Precisely accurate. ... In Interstellar, when they visit Miller's planet, there is a time dilation due to the black hole. We know in GR, the space-time is curved and light requires longer paths.
