black holes are thought to have a large gravitational pull because

• There is no mass inside of it

• it has large magnets inside of it

• not even light can escape from it

• There is a concentration of mass inside of it

The black hole appears black because

• It only has an attractive force on black objects

• the event horizon turns everything black

• It reflects only black light

• Nothing can escape its gravitational pull, not even light

The gravitational field lines for a black hole or any other mass

• Are uniform close to the mass and further away.

• Are further apart close to the mass and get close going away from it.

• Go away from the mass and then come back to it.

• Are closer near to the mass and get further apart going away from the mass.
