Temporarily Blah said:"Matter is anything with density."
Why is that so hard to understand, unless I'm missing something?
Tisthammerw said:. A similar thing happens when we try to define energy. What is energy? The classic definition is, "the capacity to do work." But wait, what is work? "The energy exerted in applying a force over a distance." Hmm, that too creates some circularity problems.

I would submit that no collision takes place, at least not in the physical sense. What azneternity may be trying to get across is that matter is composed of nothing at all, that on the fundamental level all constituents are no more than geometrical embodiments (conceptual entities).Lifter0569 said:But a certain older experiment tells me otherwise, with the gold foil and shooting alpha particles at the thin gold foil. The alpha particles would "bounce" off only when hitting the dense nucleus of the atom. And I strongly disbelieve they were opposite charges. I think in that experiment there was actual collision. But if not, correct me.
One might just as well say that the breaking apart is the result of close proximity (still no collision).Also, what about particle acceleraters? They send particles without opposite charges hurling at near the speed of light and collide and they precisely measure what occurs and how they "break apart" into their smaller constituents. That does not seem like repulsion to me.
On the contrary we have no proof of solid constituency unless you are prepared to show solid constituents on the fundamental level, and last I heard no such animal exist. This leaves the possibility of non-physical open for discussion.The whole idea of everything in the universe not having any kind of solid constituent kind of strikes me as illogical.
Empty space to me is as busy as any other location in the universe. Matter to me is the location of the foci of fundamental geometric entities, space is merely the extension of those foci.I do realize a major percentage of all the universe is actual empty space
Mass - The kind that is no more than a geometric embodiment of nothing at all, does not displace anything. This is because all of nothing is shared. If the universe is descibe as a non-physical entity, one must throw displacement out the window in favor of conceptual understandings. In other words - If the universe is not a physical entity....Physics cannot be used to explain it.The amount of matter or mass of an entity would then just turn into the volume that an entity displaces, but how is an entity to displace nothing if they are composed of nothing.
There obviously is matter. Consider the definition that first pops up on dictionary.com:azneternity said:There is no matter, nothing is solid.
So the concept of matter is not crucially dependent on the concept of solidity, and matter does indeed exist.1. a. Something that occupies space and can be perceived by one or more senses; a physical body, a physical substance, or the universe as a whole.
b. Physics. Something that has mass and exists as a solid, liquid, gas, or plasma.
From Einstein, we know that matter can be defined in words as "energy divided by speed of light squared" (M = E / c^2). This seems like a very direct and useful definition of matter. From this we see that matter must in fact exist, otherwise neither would energy exist, for we cannot have energy that is not matter moving very fast indeed.vague said:Why is matter so hard to define.

One of the main reasons why matter is difficult to define is because it exists in many different forms and states, such as solid, liquid, gas, and plasma. This makes it challenging to come up with a single definition that encompasses all the different properties and behaviors of matter.
Matter can be defined as anything that has mass and occupies space. This includes all physical substances that can be seen, touched, or measured in some way.
The concept of matter is constantly evolving because our understanding of the universe and the particles that make up matter is constantly improving. As technology advances and new discoveries are made, our definition of matter may change to encompass these new findings.
No, it is not possible to accurately define all forms of matter. This is because matter can exist in many different states and can also be transformed from one state to another. Additionally, there may be forms of matter that have not yet been discovered or understood.
Currently, scientists define matter as anything that has mass and takes up space. They also classify matter into different categories based on its physical and chemical properties, such as its composition, density, and behavior under different conditions.
