About this ebook

Este pequeno livro não é um curso de astrofísica, tampouco um estudo acadêmico, mas apenas comentários complementares, em linguagem simples, sobre alguns temas já estudados pela astrofísica, trazendo novas interpretações com o objetivo de propiciar novas reflexões, acadêmicas ou não.
Discorre sobre a razão de as noites serem escuras, propõe ensaio para a verificação de característica eletromagnética da atração gravitacional (com contraposição ao conceito de deformação do tecido espaço-tempo), apresenta nova explicação do campo magnético terrestre (com contraposição ao conceito de movimentos do manto terrestre), afirmando que somente o movimento de elétrons é capaz de gerar campos magnéticos (movimento de prótons não pode gerá-lo – um desafio que seja comprovado, ou não), explica como se arranjam os campos magnéticos estelares, demonstra ser enganoso o conceito de BIG-BANG, eliminando a necessidade de energia escura, afirmando que o universo não está se expandindo e que, muito menos, o faz de modo acelerado.
Conclui que são excepcionalmente singulares as condições de vida no planeta Terra, sendo muitíssimo pouco provável que possa existir vida assemelhada em outros planetas. Sugere que o melhor que se tem a fazer é cuidar desse nosso planeta.

    Comments on Astrophysics - Pedro Paulo Prado

    THE NIGHTS ARE DARK

    Many people have already explained this phenomenon: astronomers, scientists, poets, and lay people. So, I feel comfortable in offering my comments.

    We all know that the night is dark. It’s dark because we don’t see the light of all the stars, but they are all in the firmament – the number of stars that die is tiny, and these deaths are, in some way, luminously compensated by the stars that are born.

    The light we see from the closest stars overshadows the minimized light from the most distant stars, just as, during the day, the light from the sun overshadows the light from all the stars, including the closest ones, and similarly, the full moon also it dims the light of the stelae around it. This is easily observed with the naked eye and the same phenomenon occurs when we observe the sky through telescopes.

    We also don’t see the light from all the stars because there is intergalactic cosmic dust that absorbs the light emanating from very distant stars, so that only the closest stars are visible. Dust has existed since all times, with much of it agglomerating to form stars and planets and they are added with the explosion of some stars. It is not possible for this dust to heat up to the point of re-radiating the light received, as the light received would not be enough to heat it and, once it reaches the infinitesimal grains of dust, the light
