Comments on Astrophysics
in a simple language, bringing challenges and new interpretations about gravitational attraction, planetary magnetic fields, big bang, and othersBy Pedro Paulo Prado

About this audiobook
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.
