It helps (me) to put "things" in relation. :)Sean Jeatinghttps://www.blogger.com/profile/08978285783271305489noreply@blogger.comtag:blogger.com,1999:blog-5507673653895812509.post-22773220760096109092008-02-18T23:46:00.000+01:002008-02-18T23:46:00.000+01:00Anon,as for the first part of your question(s):Usi...Anon,<BR/>as for the first part of your question(s):<BR/>Using a 50 cm reflector telescope at the periphery of a town (with all its light) it’s just impossible. <BR/>To my knowledge currently no visual telescope would be able to identify the phenomena you mention, i.e. the effects of a <A HREF="http://en.wikipedia.org/wiki/Black_hole" REL="nofollow">black hole</A>.<BR/>Up til now one would know about what happens “behind” the <A HREF="http://en.wikipedia.org/wiki/Event_horizon" REL="nofollow">event horizon</A> as much as one knows about <A HREF="http://en.wikipedia.org/wiki/Schr%C3%B6dinger's_cat" REL="nofollow">Schrödinger’s cat</A> unless one would open the box.<BR/>What (sometimes) can be observed are , f.e. <A HREF="http://en.wikipedia.org/wiki/Black_hole" REL="nofollow">jets</A>, “rocketing” out of the <A HREF="http://en.wikipedia.org/wiki/Accretion_disk" REL="nofollow">accretion disc</A>. <BR/>Due to that the jets after their “departure” would constantly travel (almost) with light-speed for millions of years, requires an enormous and constant energy source. And this would be taken as a fairly strong evidence for the existence of a black hole. <BR/><BR/>As for the second part of your question:<BR/>Yes, as to be seen from the object details.
