How does curved space look like?
This site discusses gravity as envisioned in Albert Einstein’s theory of general relativity, covering both aspects of photo-realistic optical effects and scientific visualizations of the gravitational field based on numerical simulations.
What happens if black holes collide?
Simply, they form another, bigger black hole. However, this resulting black hole is lighter than the sum of the masses of the two original black hole. The difference in mass is radiated away as ripples in spacetime that exhibit a complex pattern related to its stretching / pulling in various directions.
Can black holes be created out of pure vaccum?
Black holes have mass. Gravitational energy is pure vacuum, but has a mass equivalent. Thus, a high concentration of gravitational energy can form a black hole – with no matter involved at all. This finding actually violates Mach’s principle, even though it was originally fundamental to GRT.
How can we study black holes at home?
Often black holes are depicted like a solar eclipse, as something dark and round in front of a bright background. However, there is surprisinglyy simple way to reproduce the optical properties of a black hole, and this method is just using simple means that most people have at home: A glass of wine.
How do orbiting black holes create radiation that we can observe at Earth?
100 years after Einstein published his theory of general relativity which predicts gravitational waves, they have actually been observed on Earth using elaborated instrumental apparatus. The observational data allowed to identiy the exact astrophysical scenario which allowed to feed its parameters into a computer simulation.
