Actually no, you are incorrigibly ignorant of Quantum Mechanics making outrageous statements.
I'm reminded for some reasons of pots and kettles and the color black.
In Quantum Mechanics at the 'Quanta level' scale, it has been objectively observed that the Quantum world that underlies our three-dimensional time/space universe does not have three dimensions and continuous time like our maco scale universe
Speaking of outrageous statements, the above certainly qualifies. Firstly, we can't "objectively observe" or "observe" in any other way any physical state, property, process, etc., as being "continuous", whether classical or quantum.
The reason for this is quite simple (or at least one reason for this is). All measurements we can ever hope to make using any measuring devices whatsoever are necessarily limited. They are not only necessarily course grained, they also must be finite and therefore contain (and record/display) at most finite information about what they are used to measure.
Thus, even if a meauring device can be so perfect that it can be made arbitrarily precise (i.e., given a measurable property of some physical system, the device can be calibrated so that the difference between the "true value" of the property and the measured value can be made arbitrarily close to zero), the device will still record/store/display at best only rational numbers.
But given any continuously distributed parameter, or indeed any interval in the continuum, one finds that the entire set of rational numbers is negligible (its measure is 0). In other words, almost all numbers are irrational.
But we cannot ever measure irrational numbers, because a single such number requires infinite information.
Second, in quantum mechanics this nonsense of the "'quanta level' scale" not having three dimensions or continuous time is balderdash. Systems in QM evolve continuously in time. As for the dimensions of the space such systems "live" in, it is not really different from classical systems. QM is usually formulated via the Hamiltonian formalism (the path integral approach is based on the Lagrangian, but the differences here don't matter) whether in the Heisenberg or Schrödinger pictures (or the interaction picture). The spaces of such systems, classical or quantum, can have arbitrarily many spatial dimensions and a single time dimension. But they must reduce or relate to our physical 3D world. QM differs from classical physics in a number of ways- in the way systems are represented formally and even more so when one brings in the observables of the theory and their mathematical properties.
But none of this means QM implies, or that our observations entail, a discrete spacetime. Relativistic QM turned out to be a nightmare that was only "resolved" by reinterpreting basic aspects of the theory only to run into formal difficulties that were themselves resolved only by reinterpreting what it means to be a physical theory as well as allowing for mathematical nonsense. But that's largely irrelevant here.
What is relevant is that QM uses the same physical space of non-relativistic classical mechanics, and the same relativistic structure as well (Galilean). It relies on continous time. It does not contain a theory of space or spacetime such that statements about the "quanta level scale" have any meaning.
Time only exists as a momentary time of discontinuous events of the basic particles of matter. as observed in cyclotrons.
More nonsense. Time in QM is continous and dynamics are (in principel) entirely reverible, just as in classical mechanics. Both theories have the same group structure as well (and even in QFT, quantum theory inherits the group structure it has from classical electromagnetism, i.e. that of U(1) gauge group).
