So, Newtonian (i´m not very keen on astrophisics) bhs CAN be seen? I mean, with a background of many galaxies that irradiate lots of light, would you see the bh itself? cause as far as I know you could only see how it´s gravity bends light arround it, and therefore, the resulting gravitational lensing<br /><br />also, I am well aware of the "shape" of a bh in a 3d space. pretty hard to imagine but it helps seing it in 2d, but it´s not the point anyways.<br /><br />Let me reformulate the question, the light that passes too close to a bh falls inside. The light that passes a little farther is trapped in orbit arround the bh. A little farther and light can escape, but it´s bended considerably. We can see this light being bended. So far so good.<br /><br />Now, again let´s get closer to the bh. A beam of light pointed at us so that it is lined up with the BH would be sucked in and we wouldn´t see it, but as the light propagates in all directions (this time not a beam) all we would be able to see is the light that passes far enough from the bh, magnified, if i´m not wrong by it.<br /><br />So the question would be whether or not there is a point (apart from the event horizon) where we wouldn´t see this light.<br /><br />(Btw, my english is not yet perfec or anithyng so maybe I don´t know how to express myself sometimes <img src="/images/icons/tongue.gif" />)
