See examples of BLACK HOLE used in a sentence. A black hole’s gravity, or attractive force, is so strong that it pulls in anything that gets too close. It can even swallow entire stars. Nothing can move fast enough to escape a black hole’s gravity. This includes light, the fastest thing in the universe. That’s why we can’t see black holes in space—they've gobbled up all the light. A null route or black hole route is a network route ( routing table entry) that goes nowhere. Matching packets are dropped (ignored) rather than forwarded, acting as a kind of very limited firewall. The act of using null routes is often called blackhole filtering.
