Have you ever study the concepts of solenoid and their uses? A solenoid is an instrument, which contains a coil of wire, acts as magnet when current passes through the coil. Then the final result is an automatic switch that is ususally used in automotive starting system.
I just want to know if black holes have the same concept. Are things always going through the black holes? Do black holes ever stop vacuuming or is it automatic like a solenoid? For example, A tunnel must have two doors in order for it to work, right? One at the entrance and one at the exit. If there is only one entrance, how can it vacuum thing into it? There are no fluidity if only a one entrance. This is applied into the h20 question--well kind of.
