Re: The universe.
according to physics we can't do crap
according to: "if you just believe, we can achieve anything", we might be able to put it back together...
according to: "m4n ez g0d" we definitely can put it back together...
(i know you meant the information part, but i was just trying to open up new area of discussion
)

@Hege: yea, don't worry about it, your style of presenting things is just different from my typical stereotype of what a geek is, and your style doesn't suit my own impression of what "scientific" stereotypically is,
so you saying you belong to both "science" and "geek" completely messed up my mind as to what that actually is

Re: The universe.
Matter is indistinguishable on an atomic level.
Hmm, guess I didn't know it then.

Re: The universe.
on a macroscopic level suddenly all sorts of intra-molecular synergy effects spring to mind, dividing us up

Re: The universe.
Why do all of the stars show up yellow? I thought most stars glowed with a white light, with the exception of some. Is it because of the contrast of the rest of the picture, or did the lens adjust so they could capture it better?

Re: The universe.
the other person is correct that stars do indeed each have their own unique mixture of energy (which comes from the elements the stars are made of), much like DNA or a fingerprint. if this wasn't the case science wouldn't be able to have all this knowledge of stars and space and other advanced super physics of the universe.
we do have technology, that does let us see other forms of energy and even to "color" those types of energy.
the most familiar such technology that let's us see another form of energy besides "visible light" is night vision goggles. the night vision goggles allows us to see infra red energy ("heat"). this allows us to "see" in the dark. the goggles show cold things (absence of infra red energy or "heat") as "green", and things that have/give off infra red energy or "heat" as "white".
we also have technology that can see radio wave energy that stars give off. usually the radio waves are "colored" as "blue" and the star looks very different when we are looking at it's radio wave energy (with technology's help) compare to looking at it's "visiable light" energy (naturally with our own eyes).
there's more such examples.

stars give of a mixture/collection of different forms of energy (radiation) like radiowaves, micro waves, infra red ("heat"), "visible light" (this is the ONLY form of energy we can see. this is why stars all apear "yelow" or "white" from far away. though we also use orange and red colors to depict their temperatures. and for stuff with lots of energy and really hot like quasars we depict them as blue. think a candle flame. white, yelow, orange, red, blue. these are the differing temperatures of the ONLY type of energy we can see known as "visable light"), UV rays, x rays, gamma rays, "background radiation". these types of energy (radiation) i listed is called the electromagnetic spectrum. these are all the types of energy (we generally know of existing. there's probably a few more, but they are for the scientists to know about, not the general public knowledge. it's like the public knows about proton, neutron, electron particles. but many people of the public don't realize there is many more particles like gluons, mesons, neutrinos, etc.. we don't really need to know about gluons only scientists. the same is probably true for other types of energy. we jsut need to know about the electromagnetic spectrum for the public use).

Go stove a jumbuck in your tuckerbag, Mr. Neutron.
It's the origin, not the view.

Re: The universe.
What is meant by that quote is that every element heavier than...Helium I think?...was forged in the nuclear furnace of a star. So we are literally made of stuff from stars.

Re: The universe.
everything comes from hydrogen. stars fuse 2 hydrogen into hellium. depending on some factors, the star can fuse hellium to carbon (not sure there's a stage/element before carbon) (and possibly this is when super nova happen and leave the carbon core?), than can use carbon and fuse heavier elements like iron (not sure there's a stage/element before iron) (and possibly this is when super nova happen, that leaves the iron core). then if the core is to dense..it can ultimately become a black hole. (i'm just going off memory, i can't remember exactly about super nova, for example)
as to where hydrogen came from, it some how was made after the big bang and inflation. the now 4 forces caused/allowed/pulled/held protons, neutrons, electrons to join together to make hydrogen atom. as to where or how proton, neutrons, electrons were made or if they already existed, i do NOT know.

Re: The universe.
Everything you see ... all that you are ... is made of star stuff.
Right on Tarnok :thumbup: The universe was already over 10 billion years old before our puny little planet formed around a mediocre G-type star in the spiral arm of the Milky Way Galaxy. The explosions of uncounted supernovas formed the gases and dust which condensed and accreted to form our planets and the sun.
Everything you see ... all that you are ... is made of star stuff.

Re: The universe.
I know what it meant, but it's a vacuous statement because there is no way to distinguish an atom that has come from a supernova from any other. What that means is that atoms do not have an origin. You can't track it from the supernova to its present location, for example. They are just interacting probability fields.

so what does that mean for us exactly?

Re: The universe.
For the star detective: You'll never be able to trace if you are made up of stardust from this or that supernova, since they are all alike. Atoms have no 'fingerprints' making them unique. They just consist of quarks, leptons, bosons and forces, and as far as we can see, these are identical. What we interpret as differences is, as you said, built up on a more macroscopic level, at least compared to the size of atoms.
But for most people it doesn't really matter which star you came from. And we all know women are from Venus and men from Mars anyway.
edit: @below: Hm, turns out my writing is worse than I thought.
In practice: Nothing at all.
