Cosmos, in general, relates to the structure and nature of the universe, and the nature of “the universe” relates to human systems of seeing, our ways of thinking and perception, and what can be seen, literally and figuratively, by humans in general. It is not only about the cosmos, it is about who we are and where we are going as a species.
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 …

This is the last book of the famous popularizer of science, astronomer and astrophysicist Carl Sagan, which was published after his death. In it, the scientist considered the issues related to various pseudo-scientific theories and popular misconceptions among the commoners. The book consistently and vividly exposes myths about Atlantis and Lemuria, clarity and various manifestations …

The development of computer technology has helped bring the modelling of the evolution of our universe to a qualitatively new level. Scientists received new information about the influence of black holes on the distribution of dark matter, learned more about the formation and propagation of heavy elements in space, as well as about the origin …

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 …
Before we know Physics let’s take a quick overview of Science. Science Definition The Study of Nature is called Science Science, as currently defined, proposes critical knowledge and tries to describe reality and explain it by means of laws that are universal propositions that establish under what conditions certain events will occur, thus allowing the …

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 …
A law on energy conservation and, in exchange, a definite description of heat is the first law of thermodynamics. The amount of energy transferred to a system in the form of heat plus the amount of energy transferred in the form of work on the system must be equal to the increase in internal energy(U) …

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 …

In giant detectors that are capable of reconstructing what happened during collisions, and all this in a very high collision rate environment, the events (an event is a collision with all of its resulting particles) are studied. They can be compared to extremely large three-dimensional digital cameras that can take 40 million “sequences” per second …
