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 …
The great challenges of today’s science require infrastructures and monstrous investments, among which are the Large Hadron Collider (LHC) – the particle accelerator that started on 10 Sept 2008, the most powerful in the world -, the Pierre Auger Observatory – the largest cosmic ray detector of the moment-, the Cassini Huygens probe – the …
Introduction to Cosmology Cosmology is the study of the origin, evolution, and structure of the universe. This science grew out of simple observations and evolved along with mathematical theories, technological advances and space exploration. Below is an attempt to describe the universe by one Arthur Dent (i.e., someone certified scientifically declined in space matters). Okay…the …

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?

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 …

Everything in this universe is manifested to our eyes and instruments in two well-known forms: matter and energy. This simple fact, which is true to how far we have come to observe – and at this point, we have come to observe very far – has given rise to numerous scientific, philosophical and even theological …
This baryonic matter that is so well known to us, at its most basic scale, is composed of quarks and usually accompanied by leptons. Leptons (such as electrons or neutrino) are subatomic particles that are subject to electromagnetism, gravity, and weak interaction, but not strong interaction (which is the strongest force in the universe, laying …
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 …

The General Theory of Relativity was published by Albert Einstein in 1915. The General Theory of Relativity is the accepted name published by Albert Einstein in 1915 for the theory of gravity. The force of gravity is a representation of the local geometry of space-time, according to the General Theory of Relativity. While the modern …

If different string theories are related, then maybe they represent different limits of a bigger, more fundamental theory. To understand the presence of objects in string theory that are not strings, but higher dimensional objects, or even points, it helps to know the formulation of Maxwell’s equations in the language of differential forms, because this …
