tabsey says:

Understanding these universe-grade events is a great step forward in astrophysics - for one thing, The BL Lacertae blazar is a particle accelerator that makes the LHC look like an asthmatic child throwing pebbles.

The most famous property of black holes is the event horizon, the
"point of no return" beyond which you cannot escape.  But even before
this final barrier you're still close to a gigantic gravitational well
built out of most of an Active Galactic Nucleus (AGN) - if not a point
of no return, it's still a "point of incredibly difficult to escape
from".  We observe vast, super-energetic near-light speed particle
streams from the poles of some such systems - what gives them the power?</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/EFE2C86D-18B1-49A7-8F3D-7CB07870581F/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
