Existence is present.

The present is the only world of existence. If we live in the present, this can be sufficiently rich and harmonious. This truth is the basis of life and science. The past is memory, the future is projection, and the present is truth. The true world exists as the eternal present. This is where our perception is completely coordinated. The past and the future appear real in our minds, but they are structures created by our consciousness. Philosophers say that the concept of 'time' itself is a construct we have created. A life focused on the present moment meets reality in it and becomes existence itself. Everything is in the present, and everything is accomplished in the present.

This can be expressed as 'Universal dynamics'.

Udynamics general equation

$$L = \frac{1}{2} g_{ij}(r) \dot{r}^i \dot{r}^j - V(r)$$

* $g_{ij}(\mathbf{r}) \cdot g_{ij}(\mathbf{r}) \cdot g_{ij}(\mathbf{r})$is a spatial geometric metric tensor,
* $\sum_{i,j} \dot{r}^i \dot{r}^j \dot{r}^i \dot{r}^j$is the rate of change of position (velocity),
* $V(r) V(\mathbf{r}) V(r) = V(r)^3$is potential energy, which varies depending on the position.

The present is the substance of truth and the clear expression of existence. This can be the fundamental philosophy of “Udynamics” and the beginning of a new science. In addition, we present the ‘Universal Hamiltonian: UH’, which is the philosophical foundation of Udynamics. The “UH equation” includes the basic premise that time has no physical entity. Therefore, this theory explains the structure and dynamics of the universe by considering only purely spatial elements according to natural principles. It does not treat time as an independent dimension, but separates it. This means that it is consistent with truth and fact and has the fundamental efficiency of nature. The UH equation is inspired by the ADM formulation of general relativity, but it presents a new approach that emphasizes the dynamics of space alone by excluding the time dimension..

$UH = g(R - \frac{1}{2} K_{ij} K^{ij})$, that is
$\mathcal{H}_{\text{U}} = \sqrt{g} \left( \mathcal{R} - \frac{1}{2} K_{ij} K^{ij} \right)$

* UH is the general Hamiltonian density.
* g is the determinant of the metric tensor of spatial geometry.
* $R = g^{ij} R_{ij}$represents the Ricci curvature (curvature of space).
* $K = g^{ij} K_{ij}$represents the external curvature (geometric shape) of space.
