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 …
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 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 …

Quantum mechanics turns black holes from cold, eternal objects into hot shrinking thermodynamics. Physicists wondered: Is there a microscopic origin for black hole entropy? If the Four Laws of Black Hole Physics looked familiar, it’s because they sound just like the Four Laws of Thermodynamics, which are: Watch on Amazon- New Black Hole Image Revealed …
Fast Facts Approximate distance from the Earth to Sun = 93 million miles (149 million km) Distance from the centre of the Milky Way Galaxy = 30,000 light-years Main components = hydrogen and helium Period of rotation = 25.4 days Equatorial diameter = 1.4 million km or 865,000 miles Relative size to Earth = 109 …
What is Dark matter? Dark matter is a major component of Cosmology and Astrophysics. In the first case, the cosmological models of galactic evolution are based on this dark matter that does not emit or block light. Since it is assumed that it constitutes 85% of the total matter, the models are based on this …
