Event horizon - Wikipedia
Black hole event horizons are widely misunderstood. Common, although erroneous, is the notion that black holes "vacuum up" material in their neighborhood, where in fact they are no more capable of seeking out material to consume than any other gravitational attractor.

Event Horizon in Black Holes: Where There Really is No Going …
At its core, an event horizon is a theoretical boundary that encircles a black hole, a region from which nothing, not even light, can escape due to the immense gravitational pull exerted by the black hole. To grasp the concept more profoundly, let’s break it down into its key components.
Event horizons and beyond: The mysterious boundaries of black holes ...
Dec 5, 2024 · This article dives into our current understanding of the event horizon, its role in black hole physics, the tools scientists use to study it, and what would happen if you fell into one!
Why is it important to study black holes? What is there to be …
Properties of the hot gas surrounding and being pulled into the black hole beyond the event horizon are not fully known. But, understanding these properties is crucial for interpreting black hole images because it is this glowing plasma that …
