These articles cover five major scientific topics: astronomy, astrophysics, physics, ecology, and evolution of life. Each field is explored through in-depth studies, theoretical concepts, and practical examples illustrating their impact on our understanding of the universe and life.
"It is absolutely possible that beyond what our senses perceive, hide unsuspected worlds. " Albert Einstein (1879-1955).
Behind this quotation from Einstein, we perceive the great scientific revolutions to come. New concepts will eventually come closer to observable facts and then be replaced by other concepts.
