Of course it's possible...you just need to stop them bombing the crap out of each other and get them talking. It's the only way that will actually work.

There are a couple theories on how this could work.

There are some parties to the conflict who will accept nothing short of Israel's utter destruction. Israel finds this unacceptable, to put it mildly. Therefore, no one solution is going to satisfy everybody.

By the end of the conflict, Israel will either exist or it won't. The only way that the conflict can end is if one of the "impassioned" sides wins and the other loses. The vast majority of the Arab community is agreeable to some kind of settlement with Israel with a nebulous constellation of agreements. The sticking point is that small minority who will not stop so long as Israel exists no matter what the regional governments do.

For one side to lose, it has to be rendered incapable of geopolitical action. Since burying them all up to their necks in concrete is impactical, they need to be killed. This entails "bombing the crap out of them." It is a necessary step. No common ground exists for diplomacy.

As evidence of the Israelis engaging in "institutional anger" as opposed to "cultural hatred," it is fairly routine for an Israeli hospital to transplant a donated Israeli organ into a Palestinian patient. The reverse has happened as well.

You mean like Ahmed Ismail age 12, who was shot by Israeli soldiers? His organs were donated into 5 Israeli children and a 58 year old woman.

His parents did it in the hope of promoting peace. If only some of the posters here showed such courage and let go of their thirst for vengeance on the people of Lebanon.

Organ donation is generally an act of altruism (a word that gives Robert the heebie-jeebies). It happens both ways without regard to religious affiliation, demonstrating that at a deep level both sides realize that human life is human life, and that said human life is precious.

Now if the governments and subnational groups in the area would simply respect internationally recongnized borders, the "Arab-Israeli Conflict" would run out of steam pretty quickly. But because those fighting the conflict see it is as "Ismlamic homeland versus the outsiders" and illogically assign the Jews to the outsider group, international borders are seen as a British and French ploy to make the Muslims play by European rules of diplomacy.

There is no requirement for the majority-Islamic countries to be members of the UN or to sign treaties with other nations. Since shortly after World War II they've been recognized as independent nations that can make their own foerign policy decisions. These nations choose to be in the UN and choose to sell their oil to foreign nations. Making these choices obligates them to operate within accepted norms of behavior, but no one seems to be willing to press them on the point.

At least we know that individual Muslims believe that individual Jews are human and (at least functionally) equal. That shows that a peaceful settlement is possible in principle.

Chuck, Israel was shooting back at people who started shooting at them. In general, they don't have "intense hatred" of anybody except the ones the ones dooing their pathetic best to murder Israeli civilians. And even then, it's a rather situational hatred based on the fact that, as small as Israel is, all of their families are threatened by Hezballah missiles. When they have completed their orders to destroy the munitions aimed at Israel and kill the people responsible for firing them, they will gratefully return to stand-down life without a glance back.

Now we have to memorize "Dwarf Planets", of which there'll be more and more as time goes on?
I'd tell these astronomers to just make Pluto an _honorary_ planet, keep the Solar System at 9, and keep almost everyone happy.

Ceres was considered a planet when it was first discovered. Doesn't it get honorary status?

And 2003 UB313 is the first celestial body named after a TV character, so it needs an honorary title, too.

And by now you've caught on that I'm just being silly.

School kids will still learn about Pluto. It just won't be one of the Eight Planets.

Pluto was actually 'promoted' from number 9 to number 1 in it's category... ;)

"You're no longer a Junior Vice President of the company, but look at it this way... now you're a senior bottle-washer!" :-)

In all seriousness, this was the most logical decision since there are likely thousands of Pluto-like KBO's in the outer solar system. Had the IAU gone ahead with its original plan, within ten or twenty years little school kids would be trying to memorize "The Sun's Family of 72 Planets" or some-such nonsense. To simplify things they'd coin a term like "major planet" and end up with the same eight we have today.

It's called a Shuttle for a reason. It shuttles people and material between Earth and Earth orbit.

No one should expect any one vehicle to do all the things that the Shuttle program currently does... because the Shuttle program wasn't designed to do all those things and somewhat-specialized vehicles would do the job much better.



Agreed, 100%. Someplace along the line, we lost our vision, our drive.

It's like requiring a plane in a modern air force be capable of all air missions because that's what the British RAF's first effective plane, the Sopwith Camel, did. With that kind of thinking we'd never have mid-air refuelers, gigantic cargo planes, etc.

It should still emit heat we could detect. There's no such thing as a perfect insulator.

Yes, I was wondering, an entire solar system and sun surrounded by one of these spheres might create a little too much heat inside wouldn't it? I don't suppose the astronomers would be pleased either if they couldn't view the universe.

Susan.

The astronomers could just take an elevator "down" to the outer surface and have all the space they could want to set up observatories that are always in "night."

The theoretical motivation to build a Dyson Sphere is to harness all of the star's output... presumably the civilization would have a use for all that energy and a means of getting rid of the waste heat. The waste heat would be the most obvious "leakage" that astronomers could look for, but there is no reason to expect it to be sent out uniformly in all directions.

Post:
I started this thread in Cafe Seti and have had a good response however some posts suggest it should be here in the science forum. Therefore, here are my ideas.

Current theories suggest that our universe came about as a result of an explosion of universal proportions, no pun intended of course. It would seem that an infinitely dense, infinitely small point of matter called a singularity exploded and through a process called inflation, created our universe.

It was thought that energy could not escape from a black hole, however that theory appears to be wrong since it is now known that energy does in fact escaped the event horizon of a black hole. It would appear that over N period of time sufficient energy escapes from a black hole thereby causing the black hole to collapse into an infinitely small and infinitely dense point of matter and then to explode.

I think a bit of your confusion comes from terminology. Black holes (according to General Realtivity theory) have a singularity in the middle and the edge of a black hole is called the event horizon. Any known form of matter or energy that finds itself inside the event horizon can never escape to outside the event horizon again. What goes on inside the black hole is actually a mystery to us, and most are uncomfortable with the predictions of General Relativity.

In short, a black hole and a singularity are not quite the same thing. All black holes are predicted to contain singularities, but it is possible for some kind of singularity to exist that doesn't involve a black hole.

If the Universe is "closed" (that is, expansion will halt one day and everything will fall back inward) then the Universe can be accurately described as a gigantic black hole with an event horizon radius somewhat beyond the maximum radius of the Universe. All future world lines lead back to the singularity (the "Big Crunch"), just as all future world lines within a typical black hole lead to the black hole's singularity.

If the Universe is "open" then the Universe started from a singularity but it is not a black hole.

The leakage and explosion you described is Hawking Radiation. I hope that you can find a good source about it because I'm still a bit fuzzy on the details. Briefly, Hawking described a virtual particle: a charged partical orbiting nothing in particular but with an orbital plane that had an X axis in normal space and a Y axis in line with time. We would see such a particle emerge from nowhere, move a short distance, fall back to the original location, and disappear again. That same particle would then travel along the other half of the circle going backward in time. We would see it as an antiparticle (antiparticle = opposite spin) appearing from the same origin as the normal particle, travelling a route of equal length but opposite direction, and disappearing at the same point as the normal particle.

With me so far? The origin point in endothermic: it leaches energy from the surroundings. The endpoint is exothermic: it radiates energy back to the surroundings. To an outside observer moving normally in time, the energy seemed to randomly organize itself in a particle-antiparticle pair that moved away from each other, captured each other by electrical attraction, and annihiliated one another (by the way, some posit that the entire physical Universe appeared as such a random organization, but that's not where I'm going here). To an outside observer who could see time as a fourth dimension much like the first three, it would appear to be a particle orbitting nothing in particular, happy to remain in a brief slice of time.

What has this got to do with black holes? When a happily circling virtual particle is run over by a black hole, it usually falls in. However, if the virtual particle is just "winged" by the edge of a black hole, one of the pair may get sucked in while the other barely escapes. The change in direction of the escaping particle (or antiparticle) leeches a tiny amount of angular momentum from the black hole, a tiny amount of energy (which is interchangeable with mass) leakage known as Hawking Radiation.

For a large black hole, only a small fraction of the virtual particles escape and the net effect is very minor. On a small black hole, the net effect gets more and more noticeable (the Hawking Radiation gets more intense) and eventually the event horizon radius (determined by the mass of the black hole) drops below a critical value and the mass is no longer a black hole. Now subjected to physical laws that we understand, a (small?) supernova is the most likely result.

The important bits for our discussion are that small black holes are inherently unstable, that large black holes do leak but at an incredibly slow rate, that from the inside of a black hole the outside world is completely inaccessible, ant that inside a black hole the total amount of energy visible to the observer could change (from infalling mass or outgoing Hawking Radiation).

Let us assume, for the moment, this idea is true. We might then consider that if one singularity created our universe then other singularity's must also have created other universes which I call the multiverse.

If we are on the inside of a truly massive black hole, the energy for the mysterious inflationary acceleration could be derived from infalling material from a "containing" Universe. Conversely, it brings up the interesting point of what is actually going on inside of stellar mass and galactic mass black holes. Probably not entire Universes (there isn't enough mass), but something more active than a point-mass.
It is reasonable to assume therefore, that the multiverse consists of practically an infinite number of universes that have been created through the collapse and explosion of black holes.

It might be interesting to speculate on the physical laws that might exist in the multiverse. Would the physical laws in another universe be the same as those in this universe?

These mini-Universes might be modelable (is that a word?) by physicists putting the initial Big Bang mass on the order of magnitude of a stellar black hole and a galactic mass black hole. Would they "explode" at all? What sorts of physical laws would dominate? Would Universal "constants" be different? Could a human in a space-ship survive a trip into such a mini-Universe (even though we are reasonably certain he could never return)?
It would seem that a lot of people on this planet believe there is some kind of an omnipotent being who looks over us and is a father figure if you will. It might be interesting to consider, if such a creature does or did exist, then what would such an omnipotent being be like in another universe or would there even be one.

Most monotheistic faiths would posit that there is one God ruling over everything. Presumably, this God would appear in ways consistent with the physical laws of each Universe (just as the same beam of light travels straight in a vacuum, deflects in a liquid, and splits into a rainbow in a prism) but would at the very least understand that there is "more than one way to do things" and act with knowledge unavailable to an observer within any given Universe.

Looks like you have your wish Octagon. Israel has been allowed it's bunker-bustersIsrael to get bunker buster bombs. Looks like business as usual, although Israel seems to be going through a little soul searching today on the success or not of their invasion of Lebanon.

That story was dated a month ago, and I'm not sure if they ever arrived in time to make a difference.

In Israel there is a tradition that partisan sniping during a conflict is unheard-of. Now that the conflict is over, Olmert is being assailed from the right and the left. Seems to be variations on "if you started it you should have been willing to finish it."

And these really "eeeevil people" are the good guys. They work for you and me. In the case that I linked to, the cluster bombs were from the US. The UK has facilitated the delivering of weapons to Israel.

Cluster munitions are used to deliver a number of small explosives in an area where the attacker wants to make sure the people in the area are neutralized (that would be the santized word for "killed or wounded badly enough that they stop fighting"). The US used to sell such munitions to Israel without question because, although in the wrong hands they can be used as "terror weapons" (imagine one going off in a market), there was never any indication that Israel would use them as such. Lately, Western nations in general have gotten phobic about civilian casualties, and the US has been hesitant to sell cluster munitions to Israel precisely because Israel's enemies tend to hide among civilians.

I don't quite follow the logic in this case... let's make Israel's job harder, and that will lead to a reduction in terror attacks??? The US State Department is still chock full of functionaries from the previous administration, and they have their own agendas that often diverge from the President who is supposed to be their boss.

The one munition that Israel either does not or cannot acquire is ground-penetrating ("bunker-buster") bombs. Because merely posessing such weapons would make Israel a threat to Syria, someone made the decision that Israel would not have bunker-buster munitions (either a dovish Israel government or a squemish US government). Hezbollah knew this and built their entire war strategy around it.

I hope that ground-penetrating munitions are either already in Israel or on their way. This would make the inevitable follow-on conflict a lot shorter and a lot less bloody.

2.) Officially diagnosed at age 5 with ADD, re-diagnosed/confirmed
ADD Diagnosis: Fall of 1993, Spring of 1994, and again: November 2004.

3.) Diagnosed with PTSD: November 2004.

4.) Short fused temperment, seeking Anger Managment assistance: August 2006.

5.) Strong possibility of Bipolar Disorder... Currently under investigation.


hhhmmm... Sane??? I think NOT!!!! (Rational, and Logical... HIGHLY!!! Definitely knows right from wrong. Good sense of humor, and has been defined by peers as "TYPE-A" Personality... "Type A's": HIGHLY STRUCTURED, organized, and efficient. Logical, most of the time... But again, SANE???)

;-D

Do I win any prizes, yet??? Do I fit in here???



"Sane" is a legal term meaning that you (assuming you are of legal age) can bind yourself in a contract using your own signature without having to get the approval of a guardian.

"Neurotypical" is the word you're looking for.
