Oh yes, along with the Pillars Of creation, it's a magnificent image to look at. Well for the time being, I don't have any normal questions regarding space matters. The majority of them, I had them answered for the past 7 years (or more). That is, unless you can give me a clear explanation, and description, of what the Bozon Higgs is. An accurate one if you please, since most sources did not have a clarifying anwer to that piece of information. Edit: after searching the chaotic twists and turns of my mind, I remembered that the hottest questions of a normal human, or in my case, every single space project that I could find information for, I had them answered from the very age of 8 (Yes people, yes. Admire the undodgable fact that I am a space nerd for nearly my whole life, up until now) Edited by labouka, Jul 2 2011, 05:40 PM.

The Higgs Boson is an elementary particle which occurs as a result of something called the Higgs Mechanism, which essentially is what gives matter mass. In particle reactions, let say an electron colliding with another electron, a variety of symmetries must hold, though they aren't similar to everyday symmetry. These include things like time (If we were to run the reaction backwards in time, we should get back to the initial status), conservation of charge, conservation of momentum, stuff like that. Now, a few decades ago, certain reactions were found which don't follow some of the conservations, called spontaneous symmetry breaking. All particle reactions are mediated (carried out) by other particles called bosons. In the electron-electron case above, the first electron whizzes toward the other one, then, since they have the same charge, just like with magnets, they are both pushed away from each other. The first electron has it's direction reversed, and the second one is pushed in the initial direction of the first. This change is supplied by a boson, which is created by the electromagnetic interference between the two electrons. Goldstone bosons are bosons that appear in reactions that undergo spontaneous symmetry breaking. The Higgs mechanism is the process by which normal bosons "eat" these goldstone bosons, and hence become real, acquire mass, and allow the reaction to continue as it should. This mechanism may leave behind another elementary particle called the Higgs boson, which, if detected, would prove this mechanism. A lot of this particle's attributes have been theorised, so we know what we're looking for, we just need 2290 square kilometres of French-and-Swiss land to build a massive particle accelerator to be able experimentally prove it's existence, and hence, prove the Higgs mechanism. I don't know how clear that was, feel free to complain if I didn't elaborate on anything. |

Well at least we have the CERN project going around. I read somewhere that the sole purpose of the CERN project is to detect the Higgs Bozon. This article also caled the Bozon "The Atom Of God", though I can't imagine what someone would be thinking about this bozon to give it such a pompous title. |

It's not the sole purpose, though it is it's primary purpose for now. And just to clarify, it's spelt boson, and they call it the God particle because as I mentioned, it is essentially what gives all other particles mass, which is kinda necessary for a lot of things. Sorry, I'm a massive pedant about things. Edited by Phimi, Jul 3 2011, 04:22 PM.

Ah I don't mind at all. I know what you mean. You have no idea how much of a pedant I can become about some things. Ever watched Monk (the detective)? Well, you can also say that I could be his very son when it comes to those things (and this is Monk we are talking about, no less). :P :P :P |

GENERIC CASTLEVANIA OPENING. *cough* Ahem. Or at least that's how it opened in the one Castlevania game I played. And you better be able to guess which one it is, too. *points to the sleeping character that is her avatar* Anyway. My question is: What do you think of Pluto? Just give me your thoughts on it. |

I smell a huge Castlevania LOS fan in here... :o :o :o :o :o HEY GUYS WE'VE GOT TROUBLE IN HERE. A non-Golden Sun fan has sliped through our numbers. Secure the Golden Sun and make sure he won't leave this place alive. Anyway, to you Phantom. My thought on Pluto? Not much I'm afraid: It's a Dwarf Planet. Kicked out of our Solar System because of this. However, Pluto is the second largest Dwarf Planet (the biggest is Other than that, there is not much of interest about Pluto's existence (but the other Pluto surely has a bigger story to tell...ten cookies if you figure out what I mean by that ;) ). |

I thought I read somewhere that Eris was actually smaller than Pluto when they could measure it semi-accurately. I could be wrong, but I might as well put that out. And I have a question: In science class half a year ago, we were in the space unit, and our teacher showed us a video where there were galaxies shown in space, and they were like seeing stars in a night sky on Earth. So, my question is, is it possible for there to be another me somewhere in the universe, given the amount of galaxies (and thus solar systems)? |

Hey... I can't be a Golden Sun fan and a LoS fan? Since when have Golden Sun and Castlevania hated each other? Anyway... When I was younger, I considered Pluto to be one of my favorite "planets", simply because I liked the name so much. When I learned it was no longer part of the solar system, it was kinda saddening. Though I've never really looked much into anything Astronomy-related since fifth grade where I studied Black Holes for an English project. To be honest, I don't find Astronomy as interesting as I did back in my elementary school days, simply because other subjects really began to appeal more to me starting Freshman year. I think plenty of you know what subject that is. :P Another question. Have you ever seen one of those space documentaries that ponders about the possibility of life on other planets or solar systems? Has it made you want to throw the nearest thing you could get your hands on? :P I remember back in my Freshman (I think, could've been Sophomore) when Suzu, me, and two other club members watched this documentary on Mars. I don't remember much about it other than the narrator pondering the chance of life on Mars and frozen water. So yeah, just tell me what you think of those kinds of theories - theories about life in other parts of space. Edit: Blue, you ninjaed me. D: (this is what happens when the computer some registers me pressing Crtl+Z instead of Shift+A. >_> ) Edited by Phantom, Jul 16 2011, 07:05 PM.

To Blue: The amount of galaxies and solar systems has nothing to do with how many 'you' exist in the universe. I believe that you must be referring to the alternate dimensions theory, where there are several 'other' dimensions that have one 'you' each, albeit with a different personality and way of thinking from the original. Those alternate realities co-exist with the parent dimension but they are not even remotely the same. An example: Even if a certain grain of sand is placed differently, in the alternate reality, than the one in the original reality, then this reality is automatically treated as an alternate reality, simply because, while the whole universe works normally as in the 'parent' one, it is not entirirelly the same: something, even a small one, differs. To Phantom: Well, I didn't say that they hated each other. I just tried to make a Golden Sun joke and give a religious tone to it (sort of like what happens in The Temple Of Kraden :P :P :P ). Apart from this, to your question: There are not many theories on the 'life on other planets' subject. Just one: H2O (Water) and C (Carbon) create life. I haven't heard of any other theory about how life can exist anywhere in the universe. And besides, I have yet to hear an alternate method of creating life (unless Frankestein escaped Earth and continues his usual whatnot rubbish in other planets, that is :P :P :P .) Why do you thing everybody is making such a fuss about the frozen water in Mars, hmm? Mars's atmosphere is dramatically loaded with Carbon. If the planet's frozen water was to melt, then all the proper conditions, required for the existence of life are in place. Is just a matter of time before that happens. And that's the reason why all searches about 'Earth clones' are based on three things: 1.Finding water on the planet. Somewhere. Anywhere. 2.Locate the Carbon and measure it's amounts on the planet's atmosphere. 3.The planet must be close to a star so that the created life has energy to preserve itself. And that's basically it... |

Well, it's wrong to say Mars' atmosphere is loaded with carbon. While it's atmosphhere is primarily carbon dioxide, the pressure is roughly what would be considered a "good" artificial vacuum here on earth, corresponding to being about 120,000 feet above sea level. Also, the majority of Mars' ice is dry ice (solid carbon dioxide), though there is again so little of it, it wouldn't raise surface temperatures that much. Even if it did raise the temperature, the water ice would vapourise immediately due to the incredibly low pressure. Also, since Mars has virtually no magnetic field, any surface life would be destroyed be the still-powerful ultraviolet radiation, though this can be limited somewhat if Mars had an atmosphere similar to Earth's (which many people believe it once did, as there are obvious signs of running water on the surface, but due to Mars' low gravity, it all kinda blew away into space). Life on Mars isn't going to start naturally, so we'll have to give it a kick-start most likely, once we've fully realised how badly we're r*ping Earth, though the process will be slow, taking almost two hundred years to being able to support microbial life to increase the percentage of oxygen, which on earth took a few million years, though again, we could help it along a bit, by somehow directing comets onto Mars to increase the amount of water it holds, and by extension, the amount of oxygen it holds. Or we could just go Spaceballs-esque. see how many of you get that. My thoughts on Pluto? Personally, I think it was a giant member on the Oort Cloud, until whatever causes comets to leave it, affected Pluto and sent it into the Solar System proper, thus explaining why Pluto has an orbit more reminiscient of a comet rather than a planetary body. Though a similar result can be found from Pluto (and Charon) being moons of Neptune, and whatever caused Neptunes crazy axial tilt, magnetic field anomalies, and for it's moon Triton to suffer from a elliptical, retrograde orbit, also knocked Pluto out of orbit, until it settled down how it is today. |

Oh how right you are on these ones Phimi. But considering the way of thinking, our Earth r*pists have, I think that, going Spaceballs is their best option. :P :P :P (turns out I got the Spaceball part, hmm?) |

I've heard of space balls but that time when we were on the road trip, space balls was voted down T.T anyways. How would you calculate the distance of a galaxy if you knew its redshift, as a difference in nm I think... |

Hmmmm...that is a tough one suzu since I'm not much into extreme calculative matters, that can be met in space subjects. But I'll do my best. Now, to calculate the distance of a galaxy, (if it's the galaxy's own distance or the distance between the galaxy and the observer you did not specify so I will go with both of them) the redshift can abbriviate to several types: the Relativistic Doppler, the Cosmological redshift and the Gravitational redshift. The most likely type of redshift that can be used for such calculation is the Relativistic Doppler, because the redshift depends on how the objects moves in accordance to the observers location: if it's moving away from him the redshift occurs but if it's moving towards him then a blueshift occurs. Redshifts and Blueshifts happen when light seen coming from an object, is proportionally increased in wavelength, shifted to the red or blue ends of the optical spectrum. It's this theory that the telescopes used for space observation use in order to make accurate calculations about a space object they are observing. How? Have you ever seen pictures like this one: Posted Image These pictures are taken from such telescopes which use red light or blue light to identify these space objects. By that method it's relatively easy to calculate such types of distances but I'm not so sure about the difference in nm you spoke of. In the cosmic levels of space it might seem a bit strange to calculate nm and such. To conclude, observation of space objects, can be done easily by the right manipulation of light and everything that is subsequent to it's use. I don't know if that's the answer you were looking for or if it's even remotely close to that but I remind you that calculations of that scale are extremely difficult for me at the time. We can at least hope that Phimi will be more into that thing and maybe give you something more than I did :P . |
