The Dual Universe

This review article focuses on the history of astronomy and astrophysics from the Renaissance era to the present time, highlighting important developments such as the remarkable discovery of the expanding universe and the detection of gravitational waves. Gravitational wave detection relies on ultra-high precision interferometry, which enables the measurement of space-time fluctuations at incredibly small scales, down to sub-attometer levels. Laser interferometers equipped with stable high-power lasers are utilized to achieve this unprecedented level of measurement precision.
Following this discussion, my recent proposal of a hypothesized model for a "Dual Universe", is introduced. The model suggests the existence of a dual universe that could potentially address two intriguing problems in physics and astrophysics. The first problem pertains to the matter-antimatter asymmetry observed in our universe. The model proposes that our universe is predominantly composed of ordinary matter, while the dual counter- universe consists primarily of anti-matter. This asymmetry may explain why free anti-matter is scarce in our universe.
The second problem concerns the origin of dark energy that drives the observed accelerated expansion of our universe. The hypothesized dual universe model suggests that the repulsive anti-gravitational force exerted by the dual counter- universe, in combination with space-time expansion, may shed light on the nature and source of dark energy.
 The matter-antimatter asymmetry and the nature of dark energy remain active areas of research, and alternative models such as the one I propose contribute to the ongoing pursuit of understanding these phenome
