The temperature of an object actually measures the degree of agitation of the molecules that compose it. The more an object is hot, the more its molecules are agitated by rapid and erratic movements; this is called thermal agitation. It is said that an object is at a temperature of absolute zero when its particle …
For the first time, the idea that the Earth revolves around the Sun arose in the minds of ancient Greek scientists. The founding father of heliocentrism is considered to be Aristarchus of Samos, who was born around 310 BC. How well he managed to work out his hypothesis is not known for certain, all information …

Our natural satellite, the Moon, has been attracting people’s views for more than one millennium. It is the second brightest object in the sky after the Sun and in many ways has an impact on earthly life, for example, it is thanks to the Moon that there are ebb and flow. The distance to the …
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 …
What is a black hole like? How were they first discovered? How do astronomers know if they’re seeing one? Since the Hubble Space Telescope was launched in 1990, there have been many observations of what are believed to be black holes, including the photograph below of a suspected black hole in the heart of 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 …

There are certain aspects of science that simply cannot be denied, no matter how much some people might try to deny them. For example, there are some people today that deny the fact that the earth is round. Today, we’re going to take a look at the simplified version of the theory of relativity, a …
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 old 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 …
