Blackholes actually exist, where as wormholes not so much as I can tell. As an astrophysicist, I spent half a year studying the mechanics, temperature profiles and evolution of blackholes. They are fascinating things and I think is reassuring to know that we have one gigantic black hole at the center of our galaxy.

Sorry to ask, but, why is it reassuring?


ha it isn't really but hey the blackhole is what is keeping the galaxy together so I suppose you could say that is reasuring to know.  Although a lot of people don't know what a black hole really is. It is the remnants of collapsed star that has a frozen event horizon. If ye guys are interested I could explain what would happen if someone theoretcially entered a black hole but I understand if ye think it is boring.

Question: How can you say that with such certainty if you have no idea what the interaction of the so-called dark-matter is with our galaxy? Even stranger is dark energy - which (the learned tell us) tend to push space apart.

I'm really flumoxed by how cosmologists and astrophycisists can speak in factual terms when there is much more they don't know than they do know...

What are you trying to get at? 

Do not put down what you do not understand. It is very easy to look up wikipedia and to find general information about cosmology to sound smart. So you trying to sound intelligent to undermine a physicist does not bode well with me.  I am sorry, I deal with your type of people at my university the whole time.

I have studied the mathematics and mechanics of black holes, and I have seen the effect black holes have within other galaxies. Dark matter has little to no interaction with galaxies. It only makes up 1% of the universe mass. Dark energy is an unknown quanity but we do know that it makes up 90 % percent of the universe. Physicist do not claim to know information about dark energy, an experiment was sent up to the ISS last month which should hopefully shed some light on this problem.
