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 …

Kepler's Laws on the Movement of the Planets

Kepler’s Laws on the Movement of the Planets

Astronomy was of interest to Kepler from an early age, but smallpox transferred in childhood hit the future scientist’s eyes hard and seriously limited him in his ability to independently conduct observations. However, interest in science has not been lost. While studying at the university in Tübingen, Kepler got acquainted with the heliocentric system of …

BOINC: A Distributed Computing System

Processing scientific data requires enormous power, but the number of supercomputers available is very limited. However, a significant part of the calculations can be broken down into small tasks that a home computer can handle. The BOINC project is a complex of programs designed to organize distributed computing.It was originally created in 2002 for the …

wave particle duality of electrons

Wave Particle duality of electrons

Is Light Particle or Wave? Bohr considered electrons as particles and light as a wave in his development, Einstein’s concept of the existence of two theories of light (waves and particles) which had not been connected in a logical way had already been accepted. Then another renowned scientist appears Louis de Broglie, who suggested a …

What is the structure of the Universe?- spacetime geometry

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 …
