The Wave Structure of Matter explains Gottfried Leibniz's Monadology
where 'each created Monad represents the whole Universe'.

Reality cannot be found except in One single source, because of the interconnection of all things with one another.
I do not conceive of any reality at all as without genuine unity. (Gottfried Leibniz, 1670)

There are also two kinds of truths: truth of reasoning and truths of fact. Truths of reasoning are necessary and their opposite is impossible; those of fact are contingent and their opposite is possible. When a truth is necessary, the reason for it can be found by analysis, that is, by resolving it into simpler ideas and truths until the primary ones are reached. .... I hold that the mark of a genuine idea is that its possibility can be proved, either a priori by conceiving its cause or reason, or a posteriori when experience teaches us that it is in fact in nature. ... It is a good thing to proceed in order and to establish propositions. This is the way to gain ground and to progress with certainty. (Gottfried Leibniz, 1670)

I agree with you that it is important to examine our presuppositions, thoroughly and once for all, in order to establish something solid. For I hold that it is only when we can prove all that we bring forward that we perfectly understand the thing under consideration. I know that the common herd takes little pleasure in these researches, but I know also that the common herd take little pains thoroughly to understand things. (Gottfried Leibniz, 1670)

...a distinction must be made between true and false ideas, and that too much rein must not be given to a man's imagination under pretext of its being a clear and distinct intellection. ... Indeed in general I hold that there is nothing truer than happiness, and nothing happier and sweeter than truth. (Gottfried Leibniz, 1670)

Gottfried Leibniz and Metaphysics

For thousands of years philosophers have gazed at the stars and known that One thing must exist that is common to and connects the Many things within the Universe. As Leibniz profoundly says;

Reality cannot be found except in One single source, because of the interconnection of all things with one another. (Leibniz, 1670)

Thus as matter interacts with all other matter in the universe, to ask 'What is matter?' is no different than asking, 'What is the universe?', or more completely 'What exists, what is Reality?'. The solution is found in One Principle which describes the One Substance which exists (Space) and its Properties (Wave-Medium) such that we can then explain the necessary connection between the many things which exist. From this One Principle we can deduce the following Properties of Space and General Laws.

All Truth ultimately comes from Reality. Thus the past errors and ultimate failure to correctly describe Reality (which is now believed to be impossible) have left modern Metaphysics and Truth with an understandably bad reputation. With help from Aristotle and Leibniz, we can now correct these errors in the following simple way. As Aristotle confirms;

The first philosophy (Metaphysics) is universal and is exclusively concerned with primary substance. & It is the principles and causes of the things that are that we are seeking, and clearly it is their principles and causes just as things that are. & And here we will have the science to study that which is just as that which is, both in its essence and in the properties which, just as a thing that is, it has. (Aristotle, 340BC)

Thus at the heart of Metaphysics is Substance and its Properties, which exists and causes all things, and is therefore the necessary foundation for all human knowledge. Most importantly, Aristotle and Leibniz were correct to realize that One Substance must have Properties that account for matter's interconnection and Motion.

The entire preoccupation of the physicist is with things that contain within themselves a principle of movement and rest. And to seek for this is to seek for the second kind of principle, that from which comes the beginning of the change. & There must then be a principle of such a kind that its substance is activity. (Aristotle, 340BC)

I maintain also that substances, whether material or immaterial, cannot be conceived in their bare essence without any activity, activity being of the essence of substance in general. (Leibniz, 1670)

The solution is to realize that Space exists as a wave-medium and contains spherical wave-motions that cause matter and its interconnected activity/change (i. e. Time, Forces).

Gottfried Leibniz’s Monadology

Thus the Metaphysics of Space and Motion agrees with Leibniz's comment,

I do not conceive of any reality at all as without genuine unity. (Leibniz, 1670)

We then realise that Leibniz's Monadology (Monas is a Greek word which signifies unity or that which is one) is largely correct, Matter and Universe are One. But we can now better understand his Monad as a Spherical Wave Motion of Space that determines the size of our finite spherical Universe within an Infinite Space, and thus interacts with ALL other matter within our Universe. As Leibniz writes;

It follows from what we have just said, that the natural changes of monads come from an internal principle, and that …change is continual in each one . … Now this connection of all created things with each, and of each with all the rest, means that each simple substance has relations which express all the others,… each created monad represents the whole universe. (Leibniz, 1670)
