Special Relativity Einstein's special theory of relativity

Special theory of relativity

The Special theory of Relativity (shortly, Special or Restricted Relativity, RE), first published by Albert Einstein in 1905, describes the physics of motion in the absence of gravitational fields. Before it, most physicists believed that Isaac Newton’s classical mechanics, based on the so-called relativity of Galileo (origin of the mathematical equations known as Galileo transformations), …

What is the structure of the Universe? Geometry of spacetime

The Einstein equation predicts several possible ways for the Universe to evolve in time and space. What are these predictions, and how do they equate themselves to observation? The starting point of a theoretical exploration of cosmology is the Einstein equation with a metric of the form It is possible to divide the spacetime modelled by this equation conveniently …

How Old is the Universe?

How Old is the Universe? (All Calculations so far)

A Bible-based assumption of a few thousand years was made by Isaac Newton. Einstein believed in a World that was steady-state, ageless. Since then, somewhere in the centre, data obtained from the Universe places the probable response. First Ingredient: Quantum mechanics    In the early 20th century, it was realized that the stability of atomic …

Classical Physics vs Quantum Physics- The major Difference

What is the difference between classical physics and quantum physics? Physics that studies and explains the phenomena that occur in the domain of atoms, their nuclei, and elementary particles are called quantum; and the basic mathematical theory that explains the movements and relationships in this field is called quantum mechanics. However, it should not be …
