# can something actually be so small that it doesnt exist?

like when saop touches water and it gets smaller ........... can it get so small that it doesnt exist ........ because size is infinity isnt it? like the galaxy compared to a cell in our body

No. No matter how small it is it exists.

By calling it "something", you're implying it exists, even if it's a microscopic amount.

In the soap and water example you gave, the soap hasn't disappeared in the scientific sense, since if the water were tested, the soap would show up in it.

Matter doesn't just "disappear". It may turn into something else, but it's still present, only in a different form. For example, you can have a piece of ice, which is considered a solid. When it melts, it hasn't disappeared or "become nothing", it's just changed from a solid to a liquid. If you leave it in the heat, it seems to "disappear", but in reality, it's turned into a gas (from evaporating). It never ceased to exist. However, the ice cube itself ceased to exist, as did the puddle of water, but the water itself never did.

Scientists are able to break open what they thought for years was the smallest particle possible (the atom). Now they know that the atom can be made up of a LOT of different things. How do we know that in 25 or 50 years, we wouldn't have found out the things that make up the atom have their own parts?

Proof that size is infinately large and infinately small, but infinately small means that it's so small we can't comprehend it, but it's still there.

To exist is to have properties, whether it be mass, spin, charge, frequency, phase, etc. Size is another such property, but even if something had no size at all, it still could have other attributes, such as phase, which is a pretty abstract thing but nonetheless can have a real presence.

Ordinary matter that we're familiar with does have a lower bound, called Planck Scale (see wiki article) which is considered by many physicists as the boundary between ordinary matter, and something currently beyond physical understanding. String theorists believe that vibrating strings reside in compactified dimensions in the order of Planck Length, or about 10^-35 m, but other theories being proposed probe even smaller features. And they are very exotic. Nevertheless, however exotic "existence" may be at those tiny dimensions, even as "ordinary properties" are squeezed out at this scale, it does not rule out the possibility of other realms of physical existence at those "so small that it can't possibly exist" scales. It's just not like anything you and I would be familiar with. For example, ordered time may even cease to exist at those scales.

Technically, anything that has mass and takes up space is matter, and if both of these criteria are fulfilled, the thing must exist. Any amount of matter, no matter how small (like a neutron in the nucleus of an atom) still exists even though even the most sensitive measuring instruments can't measure it. We don't have instruments sensitive enough to measure matter past a certain point; even electron microscopes have their limits. Think of it like this: a piece of dust may seem nonexistent when compared to the size of the universe, but it still exists--you can see it, touch it, smell it, taste it, and weigh it. Even though it seems infinitesimal compared to the universe, the piece of dust is still very real.

exactly.

the bar of soap can cease to exist because the parts that are required to form a bar of soap can disentegrate to the point where there is no bar of soap anymore. Its common sense. The tricky part there is only defining what configuartion of matter then constitutes a bar of soap and once it falls outside that tollerance of definition it ceases to exist.

matter appears everywhere around you but is not definable as existing without meeting criteria in certain configurations.

yes the particles will always be there. The chemicals may break down or take on different parts to become some other chemical. but the very basic particles in the tiniest structures will always exist.

The tiniest prtion can become tinier and tinier. Of any matter. Like something that gets bigger and bigger, the exact opposite takes place.

When you think about all ther microscopic organisms in our world, that only special advanced instruments can detect. There is always the probability that the object, at some point , would discontinue shrinking, when all atoms are compressed, and the object is left as only an atom. At which point it would get larger from there as it add on by joining other atoms positive or negative nuclei.

No. Even something as small as a single cell exists.
