Yes singularities do exist within black holes for shure. Outside them is another matter. These are refered to as naked singularities and their existance is still debated so maybe thats whay was being refered too? Cheers, Ryan Jones

Yea a tire may be better in this case Don't take my word for this though, I'm not an expert - maybe one of the physics experts can confirm or oppose it:) I'm not really shure how this would work but I don;t think space would just bond together in a hole, it would probably bounce back and retain its old shape... list like if you take the relativity view of spacetime, if you remove a heavy object from the "sheet" you get waves sent out as the sheet bounces back to its original "flatness", maybe the same thing happens here with the hole - you try to push it together and it just refuses to join Cheers, Ryan Jones

Yup, I think most (If not all) calculators do at some point. I know you guys have gone through everything in the link but maybe you cna find something there you missed to mull over http://mathforum.org/dr.math/faq/faq.0.9999.html Cheers, Ryan Jones

ea I agree with you 100%. They can't have evolved before that (Unless they could reproduce on their own or by infecting other viruses which would not make them a virus) because they could not have reproduced. But the simplicity of the virus also tells us that they must have evolved a long time ago and due to their effectiveness have never evolved. Maybe they evolved after the first single cell organisms? Cheers, Ryan Jones

Red shift is the key killer in this theory. Measring redshift accuratly as can be done today, allows us to show how long the light from some very distant objects (Billions of lightyears away) took to get where by the ammount ot has been shifted to the red spectrum as it moves away from us. I also agree with Cap'n Refsmmat - The Fabric of the Cosmos would help you a lot here (Your creationist friend should try reading this too ) also, Brain's other book The Elegant Universe also covers things along these lines too The two books are well worth the money and the reading, he really does a good job at explaining complex concepts with an easy language style and covers a lot of topics too Cheers, Ryan Jones

If you try this you'll find that the hole is not closed by compression. The hole remains although its shape has been changed. Is space folded in on its self I'm not shure what would happen. It would be wierd I'd give you that. In a sence the gravitons could escape from one side to the other and not allow gravity to escape causing a greater gravity maybe? Cheers, Ryan Jones

You should write a book - you explain it better than my book does I understand it much better now and with some practice (And some more help from my teacher too ) I should be able to get this right Maybe I'll try those excercises in the book too... Does this get easier with practice? Thanks for your help (I'll read this a few more times so I'm shure I understand what you wrote). Ryan Jones

You'd probably get a bang - Oxygen has a way of doing that to just about anyhting! You mix oxygen and fine powdered anything, add a spark and then you get an explosion - how nice! Cheers, Ryan Jones

Hi there all you physics fans! I have recently wondered about this question after watching a program on String Theory (It was great too ). How could string theory be used to explain a black hole? Would it be something like a large collection of closed strings forming lots of gravitons in one place? I also have another question. Why is the graviton massless? Is there a reason for this? Thanks for your help on these questions Ryan Jones

Yea - funny I read something along those lines just a few kinutes ago (From one of the books you reccomended!) Do you happen to know how you write these? Like how do you know how namy S fileds there are in an atom etc.? Cheers, Ryan Jones

Yea I know - we should be learning about it sometime in the next two weeks - I just like to learn ahead Cheers, Ryan Jones

Hi there everyone! I've been reading up on electron configuration and I just don't understand it at all. I know there are 4 shell types (s, p, d, f, and a hypothetical g). But I just don't undestand how to use these. Can someone explain this to me in a simple way? e.g. I know that Hygrogen has the configuration of: 1S1, Helium: 1S2but I don't understand how you'd do these as needed in say an exam. I'm much appreciate it if someone could explain how you are supposed to work these out as needed - How am I supposed to know the configuration based on the proton number (Or the electron number because they are both the same unless its an ion...)? Thanks for the help, a demonstration of the answer would also help a lot Cheers, Ryan Jones

Thats good to know - thanks for the infromation Cheers, Ryan Jones

I'm not shure but I think its the same for Silicon but as its in the metalloids group then it may be able to form ionic bonds. Cheers, Ryan Jones

Because these religions change their views to support the facts proven by science. An example being evolution to start with. Conclusion: Religions are wrong. I'm surprised they noticed... if science had not have said so then they'd still say it was flat. No... it is fact! Look at fossils you see a clear evolution and hange in species over time! Ned I say more to say why the religions point of view should not ever be taught in schools? keep science and religion apart and keep schools and religion appart, you can go to church or whatever to learn about religious nonsence. Cheers, Ryan Jones

I think jdurg just said that Cheers, Ryan Jones

I agree with that - without host cells a virus is useless (they can't reproduce) though they are very primative but very good at what they do - they must have formed as early as the earliest cells I think. the reason they have not evolved to something more modern is they have never needed too - they are still very dangerous things. As for weather a virus is alive - it could be eather and I agre this is still under debate. They can't reproduce on their own and my understanding of the definition for things lliving or not says that they are not technically alive.... Cheers, Ryan Jones

Probably those are the files that are required by windows to run - there would be no way to disable these apart form writng a program to do it yourself. Cheers, Ryan Jones

So true... in the end these techniques will be used as they can save lives - the only thing immoral here is having the knowledge and not using it. Anyone agree with that? Cheers, Ryan Jones

For the exam I m doing I am allowed to use these programs provided they have proof that I wrote them, include informaiton about the calculator and a copy of the code I used. It still only helps a little because I still have to show full workings - something my calculator can't do so its uses are very limited. It can't for example ballance equations (Though it can ballance the charges in each compound to make shure the charges of the reactants match that of the products.) Cheers, Ryan Jones

I understand. Thanks you both - your information was very useful to my research Cheers, Ryan Jones

Thorium is radioactive right? Are you shure you want to run the risk of some of it evaporating and spreading radioactive stuff over your area because that could possible happen.... Cheers, Ryan Jones
