I. What is the Void? The Void is a term used in cosmology to describe vast regions of space that appear to contain very few galaxies or other visible matter. These regions are characterized by extremely low densities of matter, making them appear empty or void of any significant structures. The Void is thought to … Read more
I. What is Galaxy Formation? Galaxies are vast systems of stars, gas, dust, and dark matter that are held together by gravity. They come in various shapes and sizes, ranging from small dwarf galaxies to massive spiral and elliptical galaxies. Galaxy formation refers to the process by which these structures come into existence, evolve, and … Read more
I. What are Boltzmann Codes? Boltzmann codes are computational tools used in cosmology to simulate the evolution of the universe from the early stages to the present day. Named after the famous physicist Ludwig Boltzmann, these codes are based on the Boltzmann equation, which describes the behavior of particles in a gas. In the context … Read more
I. What are neutrinos? Neutrinos are elusive subatomic particles that are incredibly abundant in the universe but interact very weakly with matter. They are often referred to as the “ghost particles” of the cosmos due to their ability to pass through ordinary matter without any interaction. Neutrinos are produced in various astrophysical processes, such as … Read more
I. What is Dark Energy? Dark energy is a mysterious force that makes up about 70% of the universe. It is believed to be responsible for the accelerated expansion of the universe, a phenomenon that was discovered in the late 1990s. Unlike normal matter and dark matter, dark energy does not clump together in galaxies … Read more
I. What is WMAP (Wilkinson Microwave Anisotropy Probe)? The Wilkinson Microwave Anisotropy Probe, or WMAP, was a NASA spacecraft launched in 2001 with the primary goal of studying the cosmic microwave background radiation (CMB). The CMB is the residual radiation left over from the Big Bang, which occurred approximately 13.8 billion years ago. By studying … Read more
I. What are Baryon Acoustic Oscillations (BAO) Peaks? Baryon Acoustic Oscillations (BAO) peaks are a unique feature in the large-scale structure of the universe that provide valuable information about its evolution and composition. These peaks are essentially sound waves that traveled through the early universe, leaving a distinct imprint on the distribution of matter we … Read more
