Light from the accretion disk around a supermassive black hole is scattered off the surrounding broad line region, causing a delayed echo at redder wavelengths. Reverberation mapping (or Echo mapping ) is an astrophysical technique for measuring the structure of the broad-line region (BLR) around a supermassive black hole at the center of an ...
It is a concentration of heat, light or radiation so intense that its energy forms an event horizon and becomes self-trapped. In other words, if enough radiation is aimed into a region of space, the concentration of energy can warp spacetime so much that it creates a black hole.
The event horizons bounding the black hole and white hole interior regions are also a pair of straight lines at 45 degrees, reflecting the fact that a light ray emitted at the horizon in a radial direction (aimed outward in the case of the black hole, inward in the case of the white hole) would remain on the horizon forever.

Black holes don’t gulp up everything at once, but one star’s last light is still gleaming three years later, puzzling astrophysicists.
A view of M87* black hole in polarised light Sagittarius A*, black hole in the center of the Milky Way. The Event Horizon Telescope (EHT) is an active program that directly observes the immediate environment of black holes' event horizons, such as the black hole at the centre of the Milky Way. In April 2017, EHT began observing the black hole ...
Like black holes, white holes have properties such as mass, charge, and angular momentum.They attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole's event horizon (though in the case of the maximally extended Schwarzschild solution, discussed below, the white hole event horizon in the past becomes a black hole event horizon in ...
