okay, m not entirely sure how to explain this, so bear with me.
atoms: building blocks of life.
question: is everything connected, or is it completely random?
all atoms are grouped together. there are small cracks between them. the cracks are filled up by more particles. the particles filling in the cracks have cracks btwn them. particles fill in the cracks of the particles that fill in the cracks of the particles we began with. where does it end?are there more particles?or more cracks?
btw: correct me if im wrong. i could easily be misinterpreting what ive read/heard/learned/understand/know/(and the list goes on)
so dont post if its going to be a waste of cyberspace. (i.e. “you dont know what youre tlking about”) i am aware. im here to learn.
There are not more particles between those cracks you said. At least not enough particles to make us say that those new small particles are the ones who connect the ones we said before!
Yes, there are particles that are smaller then the atoms. They are called Quarks, but they only exist in the atomic nucleous of each atom.
In the Universe, that are 4 major/natural forces know for Humankind until now! Are these forces that make the planets go around the Sun for example (gravitacional force in a macroscopic way). The same way there are some other forces exist and work in the microscopic things. Working in a microscopical size there are actually 3 forces. They are WEAK NUCLEAR FORCE (this force causes natural neutron decay (beta decay). As a result, the neutron for a short time becomes a proton), THE ELECTROMAGNETIC FORCE (that acts on electrically charged particles. It is the force that binds electrons to atomic nuclei) and finally the STRONG NUCLEAR FORCE (this force bonds quarks together. It works to stabilize neutrons, protons and atomic nuclei).
I think i understood right what you were asking. If not, please say it!
Those 4 overall descriptions are correct, as mentioned in A Brief History of Time… yet imagine this…
Our galaxy is an atom…the sun being the nucleus. the planets being electrons in shells. Our atom ties into another galaxy by ionic or covalent bond. Eh…makes since…
Photons (packets of light/electromagnetic radiation) interacting with electrically charged particles (such as electrons and protons).
The strong and weak nuclear force are interactions between other types of particles.
Gravity is still not completely understood, but is believed by most physicists to work by the same basic principles as the other forces (I don’t share that belief—but then I’m not a physicist, so you should probably rather listen to them )
To my knowledge the posts about atoms are essentially true with only a few minor quibbles.
You are getting to the edge of our understanding, but I thought that I would try to fill in some info on your question “how do we know for sure that it exists?â€
The nature of photons is that they behave both as particles and as waves. If you think of photons as waves, then they come in various wave lengths from short to long. This corresponds to their energy ranging from hi to low, respectively.
To answer your question about how do we know that they exist. We know this from how they react to other objects in our world. There is part of the spectrum of wavelengths that corresponds to the visible light which allows you to see the computer screen. Longer wavelengths allow you to feel heat, and shorter wavelengths allow for microwaves, and shorter yet can become gamma radiation. All of these things interact with the nature around us and give us a sense that they are real.
There is a well known poster that will tell you that we can not know these things for sure because then we would fall into the inductive fallacy and he is right. But, on the other hand, you could make a good living by placing bets with him that these events will happen.
Energy a an electromagnetic vibration that propagate itself in time and space! Now please notice that energy can be light for example. Having this in mind i think it gets more easy to see how can energy be based by an electromagnetic wave! It is nothing we can touch, because it has no mass, but we can feel it´s interactions between some charged particles!
celox-- Gravity actually is very know, in some things, but you also right because on other things we still dont really understand how it works!
Basicaly, gravity is just an extension at a larger point of view of the 3 otherbasic forces, but it is also something more! that´s where we start to have some doubts about it! That´s why there are 2 types of gravity at the moment! The macro one and also the micro one!
Also, and this is only my theory (which i intent to develop more), the dark matter/energy should not be forgot here! It acts exacly like gravity, but in the oposite way so in my opinion it should be considered the 5fh basical force of nature!
If you look closely, you can’t tell where your fingers end, and the keyboard begins. But you’ll also see seemingly random quantum particles. So in response to your question… both
Kezman, sense knowledge is just the beginning of knowledge. We abstract beyond that and it is true (meaning what we conceptualize in our minds compliments objective reality) as applied science demonstrates.
