text: A black hole is an object with gravity so strong that it warps the spacetime around it.
text: The edge of the dark circle at the centre is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull, not even light can escape.
text: A black hole is an object with such powerful gravity that nothing can escape from it, including light. ...
text: A black hole is an object  typically a collapsed star  whose gravity is so strong that its escape velocity exceeds the speed of light.
text: A black hole is an object so massive that its extreme gravity makes everything, even light, fall inward,” Monreal says.
text: A black hole is just an object so massive and dense that it curves space-time to the limit.
text: The simplest black holes are objects with a singularity in the centre and that are surrounded by an ‘event horizon’,’ explains Cigdem Issever of Oxford University’s Department of Physics.
text: Black holes are objects in the universe with so much mass trapped inside their boundaries that they have incredibly strong gravitational fields.
text: Black holes are objects so dense, and with so much mass, that even light cannot escape their gravity.
text: Black holes are objects with an intense gravitational pull so strong that not even beams of light, the fastest things in the universe, can escape.
text: Before Hawking’s discovery, black holes were typically thought to be objects into which things go in but never come out (the thinking actually stems in part from Hawking’s work describing singularities within black holes.)
