All i remember is learning thangs about electrons being able to be in 2 places at once...so that means we could be in two places at once (parallel universes)
Is it possible all of this (the universe) is just what the inside of an electron is made of?

I spend a lot of time pondering the same things trying to piece together the theory of everything.
I remember learning the same thing about the electrons of an atom, I know where your coming from with this.
This is the stuff that fascinates me.

man I could read books about this stuff for decades. From Carl Sagan blowing my mind putting everything into perspective, to Quantum Physics twisting my reality like a drunk driver around a metal pole.. to Hawking and other experts talking about string theory.
So epic. IWasaclown and anyone else I would HIGHLY suggest going to your local library RIGHT NOW and getting Pale Blue Dot by Mr. Sagan.
Best book i have ever read. Sparked my interest in reading like no other..

its not so much that they are in two places at once, it that each space throughout the field has a particular "probability-density" that the electron will be there at that point in time. It was first interpreted to mean that they are nowhere in between point A and B, but was then realized in can equally mean they are everywhere inbetween point A and B. They take all possible paths and by adding up through a process known as "sum over histories" you get the probability density very near 1 that an electron will take a specific path more closely recognizable by the Newtonian laws of motion.

The mysterious quantum world... I try to read about some of the laws and stuff, but it
is tough reading. All I really remember was that standard Newtonian psychics, along
with general relativity could explain/predict our world as we see it through the
classical laws. The laws that govern the quantum world of sub-atomic particles/waves
also apply the the "macro world". Because everything in our world is made up of atoms
and molecules that are made up of sub atomic particles. It is very interesting though.
I seems very likely that quantum science will be on the forefront of innovation in the
coming century. Understanding things like dark matter and energy, and being able to
predict (mathematically) how they will act under different circumstances will give us
a much greater understanding of the universe. Science is on like a hyper drive of
innovation right now. Consider just the past hundred years. Einstein, Tesla, and all
of the engineering advances. Each field of study pulls and feeds another. With each
advancement in electrical engineering/mechanics giving new tools to another field
its almost as if the advances are becoming compound or even exponential. It is a
very exciting time to be alive! With the Large Hadron Collider searching for particles
like higgs-boson, to give us a greater understanding of the details involved in creating
the universe. If found this will be a huge advance in quantum science, and helping
to further quantum science on the path of developing the TOE Theory Of Everything.
Answering ALL of the questions that humans have pondered since we had the ability.
Questions like why am I here, what is the purpose of my existence, i don't want to
dive deep into philosophy, but these are huge questions that have been a part of the
human condition since there was a human condition. 
If im wrong about something in the preceding paragraph feel free to message me with racial slurs, riddled with references to homosexuality.

Ive been reading very heavily into Quantum physics, and man it is some HARD SHIT. Common sense has absolutely no place here.. but it is all so interesting. I plan on taking at least some classes that tie into this but I was wondering if anyone here has done this before?
how hard was it?
I got my degree in physics, took lots of quantum both in undergrad and in grad school. Its great stuff, fun and trippy. All science is interesting, but quantum and relativity make physics the most interesting IMO. There are a few of us with some quantum knowledge in the science forum if you have any questions or thoughts.
edit - You are wondering how hard it is to get a physics degree? Its hard work, but most anybody can do it with enough drive and sacrifice. Undergraduate quantum can be fairly easy, not all programs go into it that deep in undergrad. Or it can be really hard, and over the top. It varies alot depending on your school and teacher.

Read some bad reviews on The Elegant Universe.. supposedly there are alot of people spreading String Theory and passing off speculation as fact. Think I might hold off on that book for a while

The best parts, I think, are where he describes quantum and relativity. Most pop-physics books follow a similar recipe, attempt to describe quantum and relativity as well as you can for 2/3 of the book and then spend the last third on whatever crazy notion the author is writing about.

Dark Energy is tearing the universe apart.... We don't really know why the electron follows
it's path around the nucleus. We can predict where it will be 90% of the time.
We know how many there are in 118 elements, and then to think about the
nucleus and all the sub-atomic particles and the work of quantum mechanics. 
For all we know, the grater polarity of our planet, or even some greater force that
we don't truly understand is one big fucking proton. And the nuclear (neutron) forces from
the sun hold us in our orbital path. Like the neutron in a nucleus of an atom.
We do not know what Dark Energy is. It is a force,
maybe its one big proton without any neutrons to bind it to anything. Dark Matter
constitutes 75% of all mass energy in the universe, and we have no idea where any of this
energy comes from. All we know is that its a force that is stretching the universe
apart. Then we have Dark Matter holding galaxies together. That's all we really know.
Oh and that Dark Matter constitutes 83% of all matter in the universe. Man we really
have no fucking idea whats going on at the sub-atomic level or on the macrocosmic
level. Its so exciting. The electrons in an atom bind to other atoms together to make
complex molecules. The energy released creates the bond. For all we know Dark
Matter is the neutron, and Dark Energy is the proton, and the planet earth is just
one big electron.
This was just stoned babble that was running through my head the other night. I figured i would post it here hoping that someone with a greater understanding about the laws of psychics would be able to tear this all part with facts. I am aware of Einstein's space time fabric explanation of gravity. And I can think of one area in my writing that could be destroyed by the application. I know that quantum science is investigating what the space time fabric consists of. I just don't know where they are yet?

I did not think that quantum theory could be applied to general relativity? I guess I missed something. Which is highly probable as I am only able to dip a toe or two into the subatomic universe before I melt.

you can't. I believe its because you can't quantize the field for gravity without getting infinity somewhere in the answer. This is where string play supposedly comes in, giving the gravatron more mass than zero and a length larger than the plank length therefor in would weed out the infinity.

DeadHearts said: Something that blows my fucking mind is the apparent fact that matter reacts differently when its being observed.

thats a common misconception.. see, in order to observe sub-atomic particles you can't just use a super microscope with an enormous lens or something. quantum physics papers use the term "observe" so loosely and usually fail to explain that in order to observe what the particles are doing, they need to use a detector that necessarily interacts with the particle in some way, most likely being hit by a laser or something. its definitely not just watching that changes the result. the "watching" in this case, involves touching the waves/particles with a detection instrument.
I think he's talking more about nonlocality, which is truly freaky. Check out Bell's Theorem and the related experiments. Basically, a particle can decay into, say, an electron and a positron. Both fly off in different directions. Each have a wavefunction that is a mixture of two states, spin up and spin down. When one of the particles is observed, the wavefunction collapses into a definite spin state. AT THE SAME TIME, the other particle's wavefunction collapses to conserve angular momentum. This means that somehow information has traveled faster than light. What changed the wavefunction of the unobserved particle? Was it the observation of the observed particle? It looks that way.
