Our Bodies Are Mostly Empty Space...;)

[ugne]

..nowadays cuantic physicists say, that our bodies acctually are 99.9% empty space? thats crazy... or that for example atom exists only when you look at it! which is even more crazy

[Neruo]

Anything new to add?

[ugne]

Anything new to add? [/b] go ahead")P anyway thats quite new for me

Well if they are counting "people" as molecular compounds then i guess it makes sense... Atoms are mostily empty space, i guess you can compair the neucleus to a baseball, in a football feild. --Or something.

[ben k]

there was a kids question thing on the back of a nesquick cereal box and that talked about our bodies being empty space. it also said if an atom was a pile or horse poo the electrons would be green flys flying a few miles from the poo

What about water molecules? Just like the universe. 3/4 black matter. Like between my ears.

It dosnt matter what molecue, even dense stuff like lead is made from atoms which are like 90% empty held together by fast moving electrons.

[Smileyguy597]

Atoms and their Atomic bonds are mostly empty space. They are also not exactly matter anyway... its the three parts that make up the atom which are energy that makes up a solid atom... The Baseball/football field analogy is a little off as far as size goes. If an atom were the size of a city about 5 miles in diameter then the neucleus would be the size of a baseball

Anyone know about resent discoveries that suggest atoms or not made of grouped orbs; but actually a cloud of different quantum materials. It's not resent but it's fairly new and people still think of the orb atoms when they think of atoms.

I read the same thing in a book, that atoms are hugely spaced. So much so that if it weren't for electrons charge repelling or attracting things, then we would all be part of everything, like mixed like soup. Like, if you hit a ball with a pool cue, the ball would pass straight through the other ball, the cue would pass through the ball, and your hands would go through the cue, and everything would be going through everything (except of course for the odd collision between hugely spaced electrons and nuclei). So ya. Imagine, if we were all space and there was no charge on electrons, then, like, my penis could be part of my brain......

Actually when you get down to quantum mechanics you know even less. I heard that there being 'revolting electrons around the atom's core' is is a theory, all you can know is a possibility of a particle (electron) being in a certain place in a certain time. Or something. The atom-model works fine however, only there is a lot to learn still.

[/b] Well, as I understand it (which isn't very well at all) how it works is something about a cat being in a box, and being alive and dead at the same time. Scientists can't tell where the electrons revolve or when, or how quickly, or how they move between the layers of electrons. It's like the electrons are all around the atom, everywhere, at the same time. Imagine a cat being in a black box, along with a vial of cyanide that will break if an atomic substance emits a nuclear particle. The half life isn't constant, so you don't know at which point a particle will be released, so you can't at any point tell if the cat is alive or dead (let's ignore it's squealing at this point) so you assume that the cat is both alive and dead at the same time. That's how the electron's revolve around atoms, somehow...

I think it's not that we assume that it's alive or dead. It is dead and alive at the same time, or so it says (unless I missread) on wikipedia. It's in quantum superposition, as long as you keep it seperate from the outside world. Quantum mechanics are funny, did you hear that they were making a quantum computer? There won't be bits, but qubits- it will be a 0, a 1 and both at the same time, if I understand correctly, meaning that the computers will be come "super charged W0osh!" using the laws of the "quantum world". This really is an interesting time to be living in, don't you think?

That's the one I meant! Thank you Quantum mechanics are funny, did you hear that they were making a quantum computer?

It's wicked cool! Although, if you think about it, it's been a pretty interesting time to be living in for the past 100 years, starting with the car, the plane, computers, cell phones, all sorts of cool gadgets have emerged, and it keeps getting better and better!

The Baseball/football field analogy is a little off as far as size goes. If an atom were the size of a city about 5 miles in diameter then the neucleus would be the size of a baseball [/b] The size comparison that I've been taught is that the nucleus of a hydrogen atom is about the size of a dime in the center of a football field, and the electron would be orbiting around the edge of the 100 yard markers. I read the same thing in a book, that atoms are hugely spaced. So much so that if it weren't for electrons charge repelling or attracting things, then we would all be part of everything, like mixed like soup. Like, if you hit a ball with a pool cue, the ball would pass straight through the other ball, the cue would pass through the ball, and your hands would go through the cue, and everything would be going through everything (except of course for the odd collision between hugely spaced electrons and nuclei). So ya. Imagine, if we were all space and there was no charge on electrons, then, like, my penis could be part of my brain...... [/b] That's impossible for me to comprehend. If electrons had no charge, then no matter would exist beyond subatomic particles. There would be no 'you'. Actually when you get down to quantum mechanics you know even less. I heard that there being 'revolting electrons around the atom's core' is is a theory, all you can know is a possibility of a particle (electron) being in a certain place in a certain time. Or something. The atom-model works fine however, only there is a lot to learn still. [/b] Electrons move at an increadible speed. If a scientist used an electromagnetic microscope to observe the electron, the charge from the microscope would move the electron itself. However, this really isn't a problem, as we don't need to know where an electron is at any given point, but rather how an electron acts.

[13redfan]

That's impossible for me to comprehend. If electrons had no charge, then no matter would exist beyond subatomic particles. There would be no 'you'. [/b] That's right, there would be no anything. Everything would be just one big seething mass of everythingness. And maybe there'd be a spark of consciousness in between at the odd occasion.

[Merlin38]

There would be no masses. If there were no electric charges, nothing would ever attract, and all protons would repel each other. How can sentience be formed from nothing?
