  1. Scientists detect fingerprints of black hole event horizon for first time

    Researchers have identified the first signatures of a black hole's event horizon. The discovery resulted from studying gravitational waves produced by the collision of two black holes. This event revealed a spacetime whirlpool and evidence of frame dragging.

    What's confirmed:

    • Scientists detected the "fingerprints" of a black hole's event horizon, the boundary from which nothing can escape, for the first time.
    • The discovery was made by analyzing gravitational waves created when two black holes collided.
    • The research was published on Wednesday.
    • The detection involved a spacetime whirlpool and frame dragging around merging black holes.
    • The event is associated with GW250114.
