Well, correct me if I'm wrong, but it seems like 'inverted light' is the reverse of 'converting mass to light'. So basically the blackhole would be absorbing light and converting it into mass. @5164 Nothing WITH MASS is faster than than light. I think theres one example (at least) where light exceeded its own speed limit. I'll try to get the exact details tomorrow (its in in article on my physics teacher's desk) As I said, correct me if I'm wrong. LazerFazer

@Pentcho Here is a contradiction in your argument. In your first post' date=' it states VELOCITY, and yet here you claim that its SPEED thats being discussed here. You are aware that when anything is accelerating, it's velocity is changing. Also, when said object is 'in orbit' or going in a circlular path, its velocity is definately changing, while the speed could be staying the same? @Atheist I also have not completed physics education in Germany, however, a friend of mine has heard this term during the mechanics section. Also, this term kan be found in the "Duden", so if you hesitate to believe, please take a look. Other than that I do agree with you so far, that it is mostly apparent from the context what is meant when a German says "Geschwindigkeit". Or, direction and speed are just referred to as seperate entities, if velocity is not to be used at all. Cheers, LazerFazer

I'm a little unclear on how not attacking Iraq portrayed the UN in that manner. Could you please clarify that? Thanks Thanks. I hope so too. And it seems like they are figuring it out, slowly but surely. LazerFazer

For two and three, just draw a free body diagram for each situation, and then do a sum of the forces in the x- and y-. It should be simple after that. LazerFazer

@ Pangloss

Interesting comparisons there. I too wonder about the relevance of both Jordan and Egypt being strong supporters of the United States. It does seem like US allies are being targeted, but as Tiger's Eye acknowledged, Jordanian youths are protesting against the attacks. Could this be the beginning of the end of AlQaeda? Also, this further prooves a statement that I made in a different thread about Islam not being a religion of intolerance and militarism. It IS a religion of peace, something that collectively we all want. Another thing... Not only is this a "logistical nightmare" in terms of the dead and injured, but also the long-term effects of these bombings. Living in Egypt, we see first-hand the economic effects of terrorist bombings, and I tell you they're not pleasent. Firstly Jordan has closed its land borders, so theres already a drop in trade with other nations. Then the tourism industry is going to suffer a major decline due to security fears. Much like the airline industry declined after September 11, so will the tourism industry in Jordan. It's a good thing Jordan has other means of foreign income, unlike Egypt which relies heavily on tourism income. Overall, I think this plan is initially going to get AlQaeda what they want (Foreigners leaving the region), but then it's going to turn back and haunt them. Who knows, maybe the world will finally realize that uniting is the only way to eradicate this foe. Now one thing that I noticed is that the policies of AlQaeda and that of the US government are similar ideologically. AlQaeda has basically declared a war against non-Muslims, while the US government has declared war on Muslims. If they work together, who knows, they might be able to destroy the entire world. Wonder who would be happy then. LazerFazer

Alright, people have repeatedly asked me to provide evidence for many of my claims, primarily the one that Islam is a religion of peace. Well, I have finally found concrete evidence that I hope will convince the many skeptics around here that Islam does not preach death, destruction, and terrorism. Just some proof, as I said, that Islam is a peacefull religion. The actual article is really long, so here is the link to it. Cheers, LazerFazer

@aommaster Not sure what the full title is... but its by Brian Greene. As for the falling apart of QM and GR, I was under the impression that it's when you use BOTH together that you get nonsense values. Such as infinite probabilities, and things like that. And yes, combining the two would be required in the case of a black hole, which is both massive (gravitationally) and miniscule (spatially). LF

I think the half-equations for the formation of NaCl would be: Na --> Na+ + e- Cl + e- --> Cl- And the same for the others. (I might be wrong tho... havent taken chem now for about half a year) cheers, LF

Well, you could evaluate whats in the limit for successively smaller values of x, thereby determining the limit. That's the brute-force method. There is another, more 'mathematical' method, which is basically multiplying the top and bottom by the conjugate of the top. So multiply the entire thing by [math] ((x+27)^{1/3}+3) [/math] on the top and bottom. Then factor out any common factors, and substitute 0 for x and solve. Cheers, LF

Have you ever heard of circular functions? They consist of many points, which have no dimension, therefore yes, it is possible.

Alright, I don't have much time, so I'll try to be quick. Well, I don't think it should be ignored. While these comments may demonstrate immaturity on the parts of the leadrs, the same comments sometimes betray their intentions of the leader. Although in this case, I question the ability of Iran to invade, and hold control of, Israel. Also, Mr. Ahmadinejad's comments MIGHT be hinting at a possible nuclear strike, assuming they DO acquire at least one nuclear warhead. In any case, I doubt the Iranian president is so blind to the facts that he would even CONSIDER an attack on a staunch ally of the US. It would be suicide, in all senses of the word. @JohnB Cheers for the vote of approval @skye I don't quite get your point. How would the Palestinian Authority fit in to the equation with Iran and Israel? @Tiger's Eye Cheers also for the vote of approval. Hope there's many more threads like this that are 'worth reading' . You also made some excellent posts there and contributed to the discussion. I'm in agreement with all your points, except one... but I'll address that later. @bettina Thanks for bringing in that news article. See, you found your own evidence of so-called 'terrorist' nations actually condemning the comments made by Mr. Ahmadinejad. As for me not being a moderator, thats true, but I was just recommending that you do a bit of research on Islam before making certain comments that you HAVE made over the past few days. The only thing I can tell you is that the leader of Iran does not represent the views all Muslims around the world. Don't take the comments of one man as your base for judging all Muslims, because it just isn't true. LazerFazer

Heres how I understand it. String theory allows for these 'tears' in space-time, because it states that little strings would 'wrap' around the tears, at the time of forming, and thus prevent the entire universe from collapsing. The key is that without strings, tears would not be possible because the universe would collapse (or a string of catastrophic events would be set off, eventually destroying the universe). Also, when these tears and re-stitchings of space-time are applied to certain Calabi-Yau spaces (the descriptions for the 6 curled-up dimensions), they re-form into a different Calabi-Yau space with the exact same physical properties as the original. This also explains worm-holes within the context of string theory. Oh, and if I'm wrong, please correct me. I'm kinda new to string theory. Cheers, LazerFazer

@ecoli: Very valid points you've made there. I just need to clarify a few of my unclear points. I've mentioned 'you' quite a few times, especially with relation to the Israeli-Palestinian conflict. I didn't mean YOU personally, but rather I meant, for example, that the Israeli civilians haven't done anything to wrong the Palestinians, and as such they should not be made to suffer because of the actions of their governments. Well' date=' what I meant was at least he hasn't proposed that the world kill off every single Israeli or Jew. Now THAT would definitely be cause for concern. More so than just calling for the eradication of a state. And yes, I agree that they Israeli people will not be content living under a foreign power, but at least they'll still be alive. But overall, I do agree with most of your points. You're an interesting debate partner. Rational, open-minded, and at least you don't hold any prejudice towards Muslims, Arabs, etc. And yes, if there was a distinct, direct, and certain threat, then I would support the use of either force or economic sanctions to diffuse the situation. The thing with sanctions though is that the local population is also harmed in the process, so more focused economic sanctions are required, rather than the Oil embargo that was placed on Iraq, for example. @bettina Now you are proving to be a tough nut to crack. It seems that your hatred for terrorists has exploded into a blind hatred of all Muslims. You fail to realize that those people calling for the eradication of Israel and of the West are a very small minority within Islam. I wonder if they would even be considered Muslims, considering they are not exactly preaching the ideal form of Islam. You want evidence? Fine, I'll give it to you. Exhibit 1 If you want more evidence, check out my previous posts. Or you could read a translation of the Quraan (as I suggested earlier) so that you see first-hand what Islam really teaches. Once again, don't bring your unwarranted, misinformed, sophomoric prejudices where they are not welcome. First get a clue, and then make an INFORMED decision. And no, CNN and FOX news don't count. @Pangloss

@skye: Good point there. See, there is an alternative to war... DIALOGUE AND DIPLOMACY @ ecoli: Well, here goes... Perhaps miseducation' date=' but miseducation arising out of desperation. Once again, look at those economic figures I posted. We always hear about the level of poverty in Africa, but nobody stands up for the Palestinians. But still, miseducation nonetheless. Another reason why we should focus our efforts on things other than basic humanitarian relief. No, I didn't mean killing the innocents as the benefit. Obviously they think that killing the innocents will have some OTHER effect, which is what I was referring to with that. I definitely do not believe that the death of an innocent is something to celebrate about. "Go to heaven and party with Allah". Excuse me, but to borrow a term from Tiger's Eye, that’s a low blow. That is not the case, and do not try to degrade beliefs in a religion simply because you do not agree with them. Yes, dying in the service of your religion is rewarded with instant admission to Heaven, but killing women and children is NOT considered in the service of religion. They haven't done anything wrong to you, and as such they shouldn't have to suffer. And no, killing Israeli's and Westerners isn’t considered a holy act, otherwise all the Muslims in the Western world would be out killing their neighbours. It just shows that there are a few people (relative) who are misguided, and that the entire religion does not support them. Yes' date=' but there's still peace, even now, decades after the conflict. That's what I was hinting at... that Arab states CAN live with Israel. Do you think that if the Palestinians had left they would have had anywhere to go back to? Israel would have seized that land, claiming it's unused, and then where would we have been? I'd rather not think about that, but its a fact that cannot be ignored. Well' date=' I'm assuming they referred to the nation of Israel, not necessarily the people of Israel, so no crime against humanity there. Although I do believe that would be against the UN charter, not sure though. I adhere to the Geneva convention, so what that says is a crime against humanity so do I. Your point? And do we REALLY want to go into the numerous military conquests over the centuries? Again, my main point here was that even when Muslims do go to war, they don't attempt to eradicate the conquered people.

Yes, that actually is an identity [math] cos(2 \theta )=cos^{2} ( \theta ) - sin^{2} ( \theta ) =2cos^{2} ( \theta) - 1 = 1 - 2sin^{2} ( \theta ) [/math] LF

@ecoli: True' date=' but we know that’s never going to happen. But don't you think that if the Arab nations see that the needs of the Palestinians are being taken care of, they might be more willing to settle their own disputes peacefully? Look at Egypt. They have a peace treaty with Israel, and nothing bad has come out of it. True, the sentiment amongst the local populus isn't on the side of Israel, but again, can you blame them? They are subject to images of their brothers (in religion at least) under occupation and under oppression. How would that make you feel? Again, once the Palestinians needs are taken care of, the situation will diffuse greatly. And good point about Oklahoma bombings. Just goes to show that its not only 'Muslims' that are 'terrorists', but also other disgruntled people. @Pangloss: I don't see how that relates to Nazi Germany. They had NO right to attempt to commit crimes against humanity. Iran, as of yet, has no such intentions. They only intend to acquire the weapons, but perhaps it would be better not to let them have it. After all, you're right, we don't know what they plan on doing with it. The best bet would be to eliminate all weapons of mass destruction. But that's an idealist view on life. That’s never going to happen. @john5746 True, the Muslims did use force, but always as a last resort. In the first few years of Islam, the Muslims usually shied away from confrontation as much as possible, and only when they were faced with no other option did they use military force to overcome their enemies. But the point that I was making is that even when force was used, never was there a needless loss of life. Oh, and Islam actually preaches tolerance to all 'People of the book' i.e. Muslims, Jews, Christians. According to the Quraan, these three religions are continuations of each other, with Islam being the final 'product' so to speak. And yes, people have used the excuse of religion to further their own goals, but these people are most definitely not holy fighters (Mujahideen). Once again, Islam only says to use force if you are attacked. Basically, fight fire with fire. As far as I know (although I could well be wrong)' date=' no other religion actually provides a framework for a political system. Mainly because the areas where they were revealed into already had an established political system, as rudimentary as it was. Arabia was a desert with many different tribes, each vying for their own supremacy. Islam brought along with it a cause to unite all the tribes of the peninsula; a common factor: religion. It also brought along a political framework, its own set of laws, if you wish, that state how a nation should be governed. If you want more info, search Sharia' or Islamic Law on Google (with the end single-quote). You know, I actually agree with you and yet I disagree with you. First, I am warmed that you used the term 'Islamic people' instead of Muslims, although that might have just been a coincidence. As I stated earlier in this post, those who use Islam as a front for attacking innocents are misguided. Islam says to only attack if provoked, and to only attack those that have wronged you or your family/tribe/clan/country/religion/etc. Although it isn't my call to make, I wouldn’t consider these people Muslims unless they make a very strong case for the argument that they were wronged in some way by the people they killed. Just killing innocents to prove a point goes against my morals and against my religion. As I said, even when the Muslims conquered enemy cities, they allowed the occupants to remain there, to keep their religion, and even left the political and social structure in-tact. They most definitely did not promote any type of prejudice or any type of mass-killing. @bettina

Wait, I thought work was a change in energy also? So would it be correct in saying: [math] W = \Delta E [/math] [math] \Delta E = mg \Delta h + \frac 12m \Delta v^{2} [/math] [math] W = mg \Delta h + \frac 12m \Delta v^{2} [/math] Also, isn't the runner applying a force onto the road, therefore HE/SHE is doing work ON the road. At the same time, the ROAD is doing work on HIM/HER? And since work is a scalar quantity, do they really cancel out, or do they just add to each other? LF

Or you could try here. Gives a pretty comprehensive list of equations. LF

Well, if a tree falls in a forest, is there still the sound wave? Yes,there is sound, but there is no NOISE, because noise is just our ear's interpretation of the sound waves. And yes, you can tell the difference between boiled and unboiled water, as has been stated here prior to my post. LF

Please, don't talk about things you have no clue about. Have you ever read the Quraan? Have you ever listened to what the 'weirdo clerics' say in the mosques? Have you ever even taken any PROPER courses in the nature of Islam or the ideals within Islam? Well then, I would say you are most definately not qualified to make any value judgements against Islam. Just take a look at the root of the word "ISLAM" (if you don't speak Arabic, then thats gonna be a bit of a problem). It comes from the word Salaam which means peace in Arabic. So, even the Name preaches peace. And the traditional Muslim greeting translates to "Peace be upon you". You want more evidence that Islam is a peace-loving religion? Of the many Muslim conquests in the past, one stands out the most mainly because both Muslims and Christians conquered this place. I'm talking of course about Jerusalem. When the Crusaders conqured it, what did they do? Slaughtered every single occupant of the city. Men, Women, Children. They 'cleansed' it completely. When the Muslims conquered, what did they do? They let people do what they wanted. Those who wanted to leave left, and those who wanted to stay stayed. Again, I tell you, Islam is NOT a religion of killing, war, lies or betrayal. Although I do agree that the future seems very bleak at the moment. LazerFazer

That sounds familiar!!! Personally, I disagree with the entire idea of eradicating any nation. It doesn't solve any problems, only creates more. And anyway, that would have to go through the Security Council, and the US will 100% veto any motion or resolution to eradicate Israel. @bettina There's no evidence that Iran is using their enrichment facilities for weapons grade material. As I'm assuming you know, even nuclear fuel for power stations requires enrichment, but not to the level that weapons-grade enrichment reaches. Do you really think that we should destroy Iran 'No matter what'? Even at the cost of millions of lives? Would that be worth it? Don't you think that diplomacy is a much better avenue than any military action, especially since the probability of mass loss of life is extremely low? I live in the Middle East, and I can tell you right now that the sentiment amongst the local population towards the US, UN, and UK (all have U's... wonder if thats significant??) isn't too friendly. I wonder why??? The three have repeatedly let the Arabs down since the end of WWII. And with no good reason. How can Arabs trust the US when they are not trusted themselves? If you really want Iran to cooperate and trust the UN, then they need to be shown some trust first. It's strange that way, but somebody needs to make the first move. And even when Iran was being frank and open with UN weapons inspectors, they still weren't trusted. Then they see what happened in Iraq, and guess what's going through their minds? "Gee.... I wonder if we'll be next??" Oh, and dont go calling a country uncivilised. It doesnt foster any productive debate, and only engages negative feelings. And as Tiger's Eye said: cheers, LazerFazer
