Black Hole Gamma Rays

[Rezgrats]

<p>Hello,</p><p>With regard to black holes, everytime I see an illustration of a black hole it has this beam shooting out of it.&nbsp; If I'm not mistaken, that beam is made of Gamma Rays.&nbsp; (if not, please let me know that too).&nbsp; Anyway, everytime you talk about black holes you hear the standard phrase "nothing can escape the power of a black hole..."&nbsp; Well, if that is the case, then how do the Gamma Rays escape?</p><p>&nbsp;Thanks,</p><p>Mark</p><p>&nbsp;</p>

As matter spirals in, it is deflected from getting close enough to the balck hole to be absorbed, and instead is shot out away from the object along the axis of rotation. Remember, a black hole has no more gravity than any other similar mass. Unless you get too close, all kind of mechanisms can transfer matter from the disk to a polar aligned jet. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
