Numerical relativity is one of the branches of general relativity that uses numerical methods and algorithms to solve and analyze problems. To this end, supercomputers are often employed to study black holes, gravitational waves, neutron stars and many other phenomena described by Albert Einstein's theory of general relativity.
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe ...
In the year 2121, Earth faces a dire threat from black holes.A team of astronauts are sent on a mission to neutralize them. Their effort is successful until their spaceship, the Endera, is sucked into one of the black holes in the Lyra Constellation, crash-landing on an Entity: a mysterious object resembling a planet.
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
New observations of several distant giant black holes suggest the mysterious entities play a strong role in shaping their environment – even going as far as to "cook" their own cosmic meals ...
Computer simulations are often the only means to study stellar collisions, galaxy mergers, as well as galactic and black hole interactions. [5] [6] In recent years the field has made increasing use of parallel and high performance computers. [7]
Computer simulation of the black hole binary system GW150914 as seen by a nearby observer, during its final inspiral, merge, and ringdown. The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as space-time itself is distorted and dragged around by the rotating black holes.
