Cosmology is a discipline that conducts scientific research on the origin, structure, evolution, and ultimate fate of the universe. It seeks to understand how the universe was formed on the largest scales, how it has changed, and what might happen in the future.The Origin of the Universe: The Big Bang TheoryThe most widely accepted theory about the origin of the universe today is the Big Bang Theory. According to this theory, the universe began to expand about 13.8 billion years ago from an extr

Hubble's Law is a cosmological relation stating a linear relationship between the recession velocities of galaxies and their distances from the observer. This relationship was established in 1929 by Edwin Hubble through the comparison of distance measurements of galaxies with spectroscopic redshift observations. Hubble's work demonstrated that the redshift observed in the light of distant galaxies increases systematically, revealing that galaxies are moving away from each other. These observatio

Have you ever wondered, “What if I had chosen the other path that day?” What if you had accepted that job offer, missed that train, or never met that person…?In our reality, these questions remain mere “what ifs.” But according to one of modern physics’ most daring and controversial ideas—the Multiverse Theory—these alternatives may all be real, unfolding somewhere else.For centuries, we assumed the universe was a single, all-encompassing entity made up of the stars, galaxies, and ourselves. But

The Big Bang Theory is the most widely accepted scientific model and theory that forms the foundation of cosmology and describes the origin and evolution of the universe.According to this theory universe, the universe began expanding approximately 13.8 billion years ago from an extremely dense, hot state known as a "singularity." The Big Bang model provides a scientific framework for understanding the initial conditions of the universe and its subsequent changes over time.Historical Development

The Big Bang Theory, or theorem, is the most widely accepted scientific model and theory regarding the origin and evolution of the universe, forming the foundation of modern cosmology.According to this theory, the universe began expanding approximately 13.8 billion years ago from a hot, dense point referred to as a “singularity.” The Big Bang model provides a scientific framework for understanding the initial conditions of the universe and the changes it has undergone over time.Historical Develo

ESO 325-G004 Galaxy is a massive elliptical galaxy located approximately 450 million light-years from Earth in the constellation Centaurus. It was first classified during observations conducted by the European Southern Observatory (ESO). The galaxy is particularly notable for serving as an example of gravitational lensing phenomena. This feature has led to its use as a model system in various studies aimed at understanding the distribution of dark matter and the matter density in the universe.Ph

Tengrism or the Belief in the Sky God is a term denoting the religious system of the ancient Turkic and Mongolic peoples. Its origins are believed to extend as far back as the Neolithic period, based on rock carvings. Information about this system is also found in written sources of ancient civilizations such as the Sumerians, Chinese, and Eastern Roman Empire.The core of this belief system is faith in a single supreme being, the Sky God (Tengri), who created and governs the universe.
