# Dark Energy Problem, Physics of Early Universe and Some New Approaches in Gravity

## Abstract

**:**

## 1. Introduction

## 2. Dark Energy as Dynamical Vacuum Energy

- (1)
- IR - limit: $t\to \infty $
- (2)
- UV - limit: $t\to {t}_{min}$.

## 3. Quantum Theory of Early Universe

- (1)
- obviously, it is small and dimensionless;
- (2)
- its variation is rapid at high energies and slow at low energies;
- (3)
- it has ambiguous physical meaning, on the one hand being an inverse entropy of the black hole with a corresponding radius up to a certain numerical factor, and on the other hand being a minimal area multiplied by the square of the corresponding curvature;
- (4)

## 4. New Approaches to Gravity and Possibility for Their High-Energy Generalization

## 5. Comments and Conclusion
