According to what we can verify and experience among the various questions of modern physics, can we somehow affirm that everything on the planet is made up of energy or matter? Can it somehow be partially affirmed, always aiming at the explanations of modern physics studied until then?

You should use more explicit titles. Hopefully a mentor will fix that. [Title fixed by the Mentors]

Kind of depends on what you mean by everything. I mean a shadow is neither. Maybe you mean that every physical phenomena can be explained with matter and energy flows? Sure.

Worth noting that the answer to this is "no", as a matter of principle. @pines-demon puts it well: all phenomena we are familiar with are explicable in a model where the Earth is made of matter, of which energy is one property. That doesn't necessarily mean it's true, but given the high precision and wide range of modern experiment, it does mean that the gaps where anything else could hide are very, very small.
 
Matter and energy are in entirely different categories. Matter is present naturally. Energy is a property of matter. It's also a property many other things.

You may be thinking that mass and matter are synonymous, they are not. It was thought at one time that mass is a measure of the quantity of matter, but Einstein's mass-energy equivalence implies that is not.

Interpreting this as a request fore "edge cases", something that we think could exist that might not fall into one of these two categories, consider the cosmological constant in General Relativity. We postulate it's existence because observations suggest the universe is expanding at an accelerated rate.

Would one consider this to be a form of "energy"? It has been called "dark energy", so perhaps the answer is yes, but it's not like we can point to some particle that produces it. "Dark Matter" has some similar issues. We think dark matter exists because of the galactic rotation curves, something that neither Newtonian theory or General relativity can explain based on observed matter. These are the two things I think of right off the top of my head - I'm not so familiar with "edge cases" in other fields.

Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As the object becomes heavier, the speed of matter falling on it for an observer on Earth will first increase, and then slow down, due to the effect of time dilation. And then it will stop altogether. As a result, we will not get a black hole, since the critical mass will not be reached. Although the object will continue to attract matter, it will not be a...
