Hello, I am trying to draw an analogy, which just came with a flash in my mind. Please clarify me, if it is wrong. Kindly note that it is an analogy only. An event horizon -- Where the light emitting is not strong enough to go inside the black hole also it cannot go outside the zone and keeps on hovering around. If I open a tap water and the water gushing down the basin creates a spherical form. The water neither can flow inside the basin, nor it can go outside. Is it this which can be thought of a black hole event horizon? Please correct me if I am wrong. Thanks.
