This app belongs to our series of educational apps focused on showing the Universe and its wonders. Black Holes includes five spatial scenes and scenarios related to the various types of black holes we have observed until now, from regular to supermassive ones (as the black hole located at the core of the Milky Way galaxy). Imagine you are travelling in a fast spaceship that has reached this 'dark' star, now directly observing its accretion disk and the orbiting bodies. The Virtual Reality mode helps you make this interstellar journey more realistic, an experience beyond imagination. This app is designed for tablets and modern phones (landscape orientation, Android 5 or newer). We are hoping that Black Holes will help you understand these strange cosmic bodies, their complex dynamics and even the newly discovered phenomenon - the emission of gravitational waves.
Here is the description of the five scenes above:
1. The first scene shows a simple, ordinary black hole of stellar mass and its rotating accretion disk (very likely to exist around this type of stars).
2. Now you can see a Quasar, a supermassive black hole (millions to billions of times the mass of the Sun) that is surrounded by a gaseous accretion disk. Two luminous, powerful plasma jets are emitted from the two poles of the star. Moreover, an ordinary star (whose orbit is very close) may be consumed in this process.
3. Two small black holes and their colliding process are the subject of this scene. The merger takes about 15 second, while these stars orbit closer and closer at increasingly speeds. In the end, the two black holes meet and merge, resulting a single, but bigger star.
4. Sagittarius A* is the location of a supermassive black hole at the center of the Milky Way. There are six stars orbiting near this black hole, and all their trajectories may be viewed in this scene (artist conception).
5. Imagine a binary star system in which the two stars (black holes, neutron stars) are revolving each other on gradually shrinking orbits. Each body emits gravitationally waves until the merger moment, and this type of radiation can be seen while propagating away from the star.
