What happens is that the equations break down ( a la Hooke's Law), so a "singularity" cannot form. Something else happens; we have to figure out what, rather than waste our time assuming that the impossible happens and basing everything else on that.

If you're saying that you don't believe in singularities, that's fair enough. That's entirely different from not believing in black holes at all. The idea of a black hole is not in the region where equations break down, their behaviour is well defined and predictable in the regions where we can observe them (e.g. gravity, behaviour of material falling into them, Hawking radiation).

You really should look up more sensible formulae, like the functional Schrodinger equation.
This backs up the (far more sensible) idea that the density required to form a black hole can never be reached -- again, Hooke's law applies.
Everythinghas an "elastic limit"; it just so happens that the completely idiotic idea of it being possible for matter to collapse as far as a black hole was too much of a wet dream for too many people, so they did everything they could to make it real.
Bear in mind that no black hole has ever been found, but evidence of other things has been bent to make it look as if there are black holes all over the place, to satisfy the too-childish desires of black-hole aficionados (in pretty much the same way that "inhabitable planets" are being found every three minutes, these days).

Okay so what do you think is at the centre of the galaxy? Or if there isn't a very massive invisible thing there, why do the orbits act as if there is? Your explanation has to also fit the evidence and be more plausible then the consensus one ...

A thing or things that cause a lot of gravity to be exerted, the same as there is in the spiral arms, and the same as there is in the centre and arms of all observable galaxies.
Black holes are really not needed as part of the equation. There's just matter, taking up not too much more room (from our observation point) than a black hole would take up.

Well there is strong evidence that there is at least one bloody big one at the centre of our galaxy.
Mark_Wallace wrote: then the total mass of the universe shoots up to infinite,
Well the one that is postulated has a mass of something like 6,000,000 solar masses - not quite infinite?

I'm not saying you're wrong - but what evidence do you have to support that - or what is your refutation of the significant evidence thus far?

Um, the scientific method is to provide evidence to support claims about what exists, not to provide non-existent evidence to prove that something does not exist.
Try providing evidence that that the Invisible Pink Unicorn, et al[^], do not exist.

I can understand why they only play that "game" once a year.

The original game in the UK was pretty much like that (which must be why they call it "calcio storico")

Pshht! 'Basic stuff' is used by those Java guys for everything that's forbidden by their religion. Ask them to do 'basic stuff', like managing memory themselves, and you risk starting a holy war.

How do you know you want to do it in Java? Java Swing in particular is a horrible mess and if you're starting a UI application from scratch and have no other reason to use Java I strongly recommend you do it in C# (though I'm not going to start the WinForms/WPF holy war just here).
For databases you want to research JDBC which is the Java connector to ODBC, and possibly an entity mapping framework like Hibernate.
I'm afraid I don't have any book recommendations for you as (i) I'm not really a Java guy and (ii) I just use Google and the Internet to find things these days.

For new members it's hard to get a display name that's your actual name. Almost impossible. However, we have tons of members who really don't care if their name is the same as someone else's name.
I was thinking that it could be interesting to open up Display Names so that you can choose whatever name you want, even if it's been taken by someone else, with a small cavet: If you haven't contributed a message or article, question or answer, your display name is plain text and it will be displayed in gray.
Each time you contribute, or each time you change your name, your name is checked against the list and if you're account is the only account with that name that has made a contribution then your name is yours and is unlocked to accept HTML, and will (by default) be displayed in a dark font.
Thoughts?

I'd be inclined to restrict all display names to plain text. Are there any good examples of HTML display names?
Letting users choose and use display names which are already in use could easily cause confusion. Imagine how many spam posts we'll get from "Chris Maunder"! Even without the radioactive Bob icon on the post, we might still fall for it.
You could try adding a counter or member ID after the name, but after a couple of pages of arguments between "Chris Maunder 3276412" and "Chris Maunder 3267412", would anyone be able to keep track?
