Remember that super-pulling space around a black hole—the one with the strongest pull in the universe? That super pull is the close-up gravitational power of a black hole. Here in this zone, the gravity is so intense that nothing can move fast enough to fly, launch, jump, or zoom away.
Around this extreme zone is a boundary called the event horizon. This boundary acts like a point of no return. Once past it, there's no going back. Only black holes have such extreme gravity zones, and only black holes have event horizons. This is what makes a black hole different from everything else.
According to context clues, which is the best definition of event horizon?
an area with not many events occurring near the horizon
an area with many events occurring near the horizon
a border surrounding very weak gravity found around a black hole
a border surrounding the zone of strong gravity near a black hole
1 answer
The best definition of "event horizon" based on the context clues provided in the excerpt is:
a border surrounding the zone of strong gravity near a black hole.
This is supported by the explanation of the event horizon as a boundary related to the extreme gravitational pull of a black hole.
