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.  

1. I have a degree in Theoretical Physics and I'm doing MSc in Nuclear Physics so please don't try and patronize me with the 'anyone can look it up in Wiki' nonsense.

2. You have coyly avoided my first response to your statements. That was certainly the most important one as far as I am concerned and I would prefer you to comment on that as a future doctorate of science.

3. Comment #2 (quoted above) wasn't made in any accusative way; I assume you took it that way due to my 1st Comment. Note, that first comment isn't directed at you, but at the statements you made. They are in no way unique or out of the ordinary.

4. For a Astrophysicist you seem to not now that (drumroll as quote from wikipedia gets copied and pasted) ''...From these figures, dark matter constitutes 83%, (23/(23+4.6)), of the matter in the universe, whereas ordinary matter makes up only 17%''  http://en.wikipedia.org/wiki/Dark_matter As everyone can see now you are quite far from the actual accepted fact above.

Q.''What are you trying to get at?''

A. Something very simple really; I observe more and more that the scientific world view is impregnating general society due to the average man being intimitated by complicated terms and guys with PhD's, not because that model that you have built up with your sketchy data is fail-safe.

This is an important topic for me since there are less and less intelligent people willing to stand up to the ego-fuelled Dawkins and co - therefore I must go down this route.

Here's a cosmology question for you (in all seriousness): How are the distances between stars measured?

EDIT: Because anyone following religion these days is considered a lesser mortal by above mentioned scientist and his many followers. So-called disciples of rational thought.
