Title Journey around and within a black hole… and in a planetarium
Abstract Most relativistic effects, whether due to special relativity (aberration, Doppler effect) or general relativity (distortion of light) have been extensively documented for decades. On the other hand, the works on visualization of these and the attempts to render them as realistically as possible are less common. Given the fact that they occur with an intensity that is sometimes highly variable depending on the direction of observation, their simulation is particularly suitable for a hemispherical projection such as that offered by a digital planetarium. In addition, some effects still remain poorly documented, such as the visual translation of extreme tidal effects within a black hole, or the crossing of a wormhole. Taking advantage of the immersive environment offered by the planetarium of the Cité des Sciences, I will present in this seminar a set of relativistic effects of increasing complexity as they would be perceived by an observer located close to, or even inside various types of black holes.
