motion or spinning and there is not a visible reason for this motion and the invisible reason has an effect that appears to be caused by an object with a mass greater than three solar masses (too big to be a neutron star), then it is possible that a black hole is causing the motion...
It goes like this: the gravitational force between two objects is equal to the mass of one times the mass of the other, multiplied by a very small number called the gravitational constant, and divided by the distan...
Neutron MonitorRandom CoincidenceNeutron MultiplicitySecondary NeutronEvent multiplicities are studied using a unique high-speed detecting system for neutron monitors. It is shown that small and large multiplicities are produced by different physical processes....
Neutron Star Crash Stellar black holes are also created when two neutron stars, which are small, dense stars made of the core of dead stars, crash into each other, like bumper cars in space. The collision sends out a giant burst of radiation called a gamma-ray, as a new stellar black ...
Such objects include brown dwarfs, exceedingly dim white dwarfs, neutron stars and even black holes. MACHOs probably contribute somewhat to the dark matter mystery, but there are simply not enough of them to account for all of the dark matter in a single galaxy or cluster of galaxies. ...
supernovae, they blast their elements to space. The best example of a supernova is the Crab Nebula, in Taurus. The core of the original star is left behind as the rest of its material is blasted to space. Eventually, the core could compress to become a neutron star or a black hole....
if a visible star or disk of gas has a "wobbling" motion or spinning and there is not a visible reason for this motion and the invisible reason has an effect that appears to be caused by an object with a mass greater than three solar masses (too big to be a neutron star), then it...
Some will get a lot heavier and become strange quarks. Our familiar iron atom will be long gone. We will have squished it into an equal mix of up, down and strange quarks -- in other words, into a strangelet. A strangelet is a small piece of strange matter. Physicists found it ...
Next, free neutrons must be introduced into the supercritical mass to start the fission. Neutrons are introduced by making aneutron generator. This generator is a small pellet of polonium and beryllium, separated by foil within the fissionable fuel core. In this generator: ...
Recent aspects regarding quantum properties of very small black holes (which are not subject of our article but are important to get a complete picture of the envisaged properties of back holes) are given in e.g. [19, 20, 49, 142, 168, 261]. The same mathematical formalism allows us to...
