Quote:To put it rather bluntly (and make it sound far more trivial than it truly is), a lot of theoretical physics amounts to "this is our best guess until we get more data".
it's more like "these are the only explanations that fit the current data"
as for the big bang, well, we can recreate mini big bangs in particle accelerators and the models we have for the actual big bang allow us to predict the behavior of these laboratory big bangs. |

Tsadkiel, I thank you for your replies to my questions and truly respect your field. But I don't think that you are reading what I am typing. I surmise that you probably exalt the pursite of science in such a way that anyone who questions it ends up royally pissing you off.
That is not atypical behavior by any means, it is in actuality, fairly commonplace. So for the sake of the continuation of this thread, I shall now digress.

excuse me, but this is third time i will be posting this. scientific theories explain WHAT is happening and HOW it happens. we know EXACTLY HOW quantum tunneling works. you are looking at the evidence right now apparently! you have things like a memory stick! hell, i've been doing quantum tunneling calculations in my classes for over 4 years now!
WHY quantum tunneling exists. WHY electrons behave as both a particle and a wave are a different story. to my knowledge we don't know yet! |

I think we can agree that "only" is a bit of a stretch. It's a "best fit" model...but that's a big part of science. It's just important to understand that such theories rarely last more than a decade before some discovery turns them on end and forces quite a bit of recalculation. |

sure can! this equation comes from Special Relativity (not to be confused with General Relativity) and appears when you start trying to describe mechanics in reference frames moving at relativistic velocities (velocities approaching the speed of light). when you try to do this a factor known as Gamma appears...
Gamma = 1/sqrt(1-V^2/c^2)
where V is the velocity of the frame. for V < c, Gamma > 1. for V -> c, Gamma -> infinity, and for V > c, Gamma is imaginary (which is a whole other topic).
Gamma tells us how space and time change relative to your velocity. these effects are known as Lorentz contraction and time dilation . once we derive how space and time change in relativistic frames, we can derive how velocities will change (suppose you see a ship pass near the speed of light and a person on the ship tosses a ball around, what do you see. in this case, V is the velocity of the ship. the velocity of the ball is the quantity we needed to derive). once we have velocity we can derive momentum and energy!
when we derive the total energy of an object in the context of special relativity we get a trailing term of gamma*m*c^2. notice that when the velocity is zero this term will remain as just m*c^2! so this energy is around even when an object is at rest (the reason we never noticed this before is because energy is always conserved and this term would appear on both sides of any conservation equation we would usually encounter) and so we call it the Rest Energy. the most common interpretation of this is that this is the energy required for the object to exist as matter.
in an explosive nuclear reaction, the constituent particles that make of the fuel collide with each other at relativistic velocities and can be partially (sometimes completely) converted into energy. the amount of energy yielded in these collisions is proportional the m*c^2 for the particles in question. |

TRUE! only is a bit extremist of me. so long as we agree that "best guess" doesn't really do it justice XD
also, yes, love XKCD. have you read any of the Saturday Morning Breakfast Cereal comics?

Here are a few others.
1. I read somewhere that although our sun is a "very average main sequence star" recent observations seem to indicate that it's output is somewhat more regular then others like it. Any truth to this?
2. After the big bang, why was only hydrogen formed? I always figured that it would make sense if heavier elements were created do to the great energies and pressures involved. It was far more powerful then a super nova, so why did it not also create heavy elements like super nova do?
3. Cosmic background radiation, why is it only in microwave frequencies, and more importantly, what was it's original frequency before it was red shifted?
4. Has anyone detected wavelengths shorter then gamma waves involved in say... splitting protons into quarks as oppose to just splitting atoms?
Thx! |

Questions: 1) How much antimatter would it take to explode the Milky Way Galaxy? 2) How much would it take to explode just a tiny, tiny corner of it? Say, Wall Street, for example. 3) Is there a way to make an antimatter containment field, say a very tiny one, that is also soluble in water. Or maybe soluble in digestive system acids. And said container could be hidden in, say, an Altoid mint. Is that possible? 4) Where can I get some antimatter? |

good ones! yay!
1) so, some background for those who may not be familiar with it. the Main Sequence is a long, continuous band that is formed when you make a plot of a stars color vs how bright the star is (spectral class VS absolute intensity or luminosity) for many many stars. the "average" stars we have observed live somewhere on this band and during the course of their life, travel along it to other parts of the diagram.
now, the short answer to your question is i don't know. if it is, i haven't heard of it, but that doesn't mean it isn't the case. because the plot is only one of color vs intensity, the time behavior of a stars emissions is not taken into account. if we were to quantify and measure the regularity of stars on the main sequence we would probably see something like a normal distribution or bell curve. it may very well be that the sun is on the "more regular" side of this curve. i will do some reading and try to get back to you when i find anything.
2) i made a post about the big bang earlier in the thread if you haven't read it yet =D basically, the key thing to remember is that we start with just energy, and as the universe expands this energy condenses into elementary particles like quarks and leptons. now, the leptons are the electron, the muon, and the tau, but only the electron is stable, so eventually the muons and taus should decay away.
as for quarks, we have observed that they only form particles in specific numbers: 2 quarks, 3 quarks, and we think 5 quarks. (there are other higher groupings but we haven't seen 5 yet). two quark particles are called Mesons and all mesons i know of have a very short lifetime (the pi+- meson, one of the most common mesons, has a lifetime on the order of 1E-8 seconds). 5 quark particles are simply called Pentaquarks (literally, 5 quarks). we have yet to observe a pentaquark in any of our experiments and the conclusion is that they are either can't form for some reason, or have an incredibly short lifetime. so this leaves 3 quark particles, which are called Baryons. of all the baryons, the proton and the neutron are the most stable. the neutron has a lifetime of about 885.7 seconds when it isn't in the nucleus of an atom or clustered with other neutrons, so they would decay. the most stable baryon we know of is the proton. IF it has a lifetime, we haven't observed its decay yet. current calculations put the lifetime of the proton beyond the current age of the universe.
so what does this leave? protons, electrons, and very few neutrons; 1 proton + 1 electron = 1 hydrogen! (there's probably some stray helium in there too from the old neutrons, but i don't think there would be very much. i haven't made any calculations).
3) the frequency of the Cosmic Microwave Background has to do with the the temperature of the universe at the time it was formed. when an object is heated, it emits a continuous radiation spectrum (so the amount to radiation you measure as a function of wavelength forms a smooth curve). this kind of radiation is called Black Body radiation and it has very specific characteristics that allow us to link the radiation we see to the temperature of the object that emitted it. the cosmic microwave background corresponds to a black body temperature of 2.7K +- .00057K (yes, we can make the measurement that precisely) and the peak of its frequency distribution lies in the microwave range (hence the name). if we take our current measurements for the expansion of the universe and project backwards, this corresponds to a temperature of 3000K ! (water boils at a temperature of 373K).
4) Gamma radiation is what we call any radiation beyond X-rays. the gamma ray spectrum starts at a wavelength around 1E-12 meters. so yes, we have seen some pretty intense stuff coming from subatomic collisions, but we just call them gamma rays heheh. |

1) oh man, i have no idea. if you wanted to Annihilate the milky way (convert it into pure energy) you would need 1:1 matter to antimatter
2) well, a single gram of antimatter would release 9E13 joules of energy (1E-3 * 9E16) which corresponds to an explosive yield of 21.4 kilotons (21,000 tons of TNT). the bomb that destroyed Nagasaki had an estimated explosive yield between 20 and 22 kilotons. will this do?
3) not at the moment. the issue with making an antimatter container is that, if you make if of matter, the antimatter annihilates and you esplode. if you make it out of antimatter, well, then you can't touch it or you will esplode. the current method for antimatter containment is acceleration rings, where streams of atoms of antimatter are suspended electromagnetically and kept moving around a large ring (with diameters usually measured in units like the mile or the kilometer).
4) Geneva Switzerland. they make it there one nucleon at a time. good luck lol |

No one is going to take you seriously if you can't do something simple and pop science-y like that!
I wonder if it would make more sense to use it all at the middle of the galaxy and watch the blast spread out over millenia until the galaxy is obliterate, or throw some in each star and see what happens. i'm betting the latter, even if it would be far less spectacular.

Quote:Random semi-related thought question: What happens if we throw antimatter into a black hole? (I'm pretty sure I know the answer)
this is actually the basis for the emission of Hawking radiation and the evaporation of black holes. current theories suggest that the black hole would be reduced in mass by the mass of the antimatter added to it. because the conversion is into energy, another good question would be what happens to the total energy and entropy of the black hole. we briefly touched on entropy calculations for black holes in thermodynamics and it's actually pretty interesting! the long story short of it is that the entropy of a black hole is directly related to its surface area. changes is mass will cause changes in surface area, and also changes in things like temperatrue, angular momentum, charge, and a whole mess of other quantities. this means we can pull all of this information about the black hole just by measuring its surface area.
now, HOW to go about measuring the surface area of a black hole... well... that's a whole different problem lol |

Referring to one of the OP's earlier posts about the fate of the universe where heat death occurs. Assuming over time large parts of the universe cool to absolute zero creating a Bose-Einstein Condensate on a large scale, what could be the result? Scientists who have created such matter in a lab with just a handful of atoms have reported strange things; matter acting as a single entity or in soome cases imploding (Bosenova). Might this point to a cyclical nature of the universe, like a really cold Big Crunch? |

I guess I'm a noob when it comes to science.... Though, I've read almost every post up to now and first started when it was at page 3. Then every time I read a page, there was another, I actually went to bed an hour later last night reading all these posts, lol.
If space is a vacuum, how exactly does heat travel from the sun to earth and keep us warm? Is it as simple as traveling with the light? As you mentioned earlier light can travel through a vacuum.
Also, given unlimited resources (Money, man power etc) and our current technology, exactly how fast of a ship could we potentially build at this moment in time? |
