In modern science, cosmology is divided into two branches.Observational cosmologystudies the universe using telescopes and other equipment to examine the direct evidence of the universe’s development and struc
Recently the interplay between astrophysics-cosmology and particle-nuclear physics became more essential for the development of research in both fields. In this paper we review recent important interplays between these fields, in particular, we discuss supernova explosion in more detail....
Cosmology is a science that studies the cosmos as one entity, instead of breaking it down into different sections such as the stars, black holes and galaxies. Its main questions are concerned with where the universe came from, the history of stars, and the nature of galaxies. In essence, i...
Cosmology started by branching off from early (1900s) theoretical physics, which used a static model (as opposed to an expanding model) of the universe. The static model of the universe is an approach based on Einstein's theory of relativity....
Why is there a 'crisis' in cosmology? What happened before the Big Bang? How many galaxies are there? Edwin Hubblecalculated the distance to afuzzy nebulous objectin the sky and determined that it lay outside of the Milky Way, proving our galaxy to be a small drop in theenormous universe...

In physics, viscosity is often expressed using Isaac Newton's equation for fluids, which is similar to Newton'ssecond lawof motion. This law states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will...
What is cosmology? What is the geometry of the space-time concept? What is Coriolis force? What is simultaneity in regression? What does flat space-time mean? What is lordosis? What is accelerated divergence in evolution? What is S-shaped scoliosis?
Velocity is defined as a vector measurement of the rate and direction of motion or the rate and direction of the change in the position of an object.
Early Universe Particle PhysicsPhase Transitions in the Early UniverseWe explore the nature of a certain type of supercooled phase transition, where the supercooling is guaranteed to end due to the curvature of the finite-temperature effective potential at the origin experiencing a sign flip at some...
