Newton: Every action has an equal and opposite reaction.
Black holes: gravity is so powerful that sucks suck everything up like a giant. That's all, even light.
It came because of the laws of Newton. For every action there is an equal and opposite reaction. The action is being discharged into the water from the pipe under high pressure. The reaction of water into the tube by having the same force. The same concept can be used to explain how they propel a spacecraft.
On the black hole, I think it is because of the curvature of 3D space by gravity. This explains why a star's light bends when it comes between the sun and Earth. Not sure if this is the answer you want.
A hose back, because every action has an equal and opposite reaction. Action in the example of the pipe, the pressure that pushes the water hose outside. This measure leads to a backlash that pressure on the pipe in the opposite direction of the water is.
