About this book

Este pequeno livro nĂŁo Ă© um curso de astrofĂ­sica, tampouco um estudo acadĂȘmico, mas apenas comentĂĄrios complementares, em linguagem simples, sobre alguns temas jĂĄ estudados pela astrofĂ­sica, trazendo novas interpretaçÔes com o objetivo de propiciar novas reflexĂ”es, acadĂȘmicas ou nĂŁo. Discorre sobre a razĂŁo de as noites serem escuras, propĂ”e ensaio para a verificação de caracterĂ­stica eletromagnĂ©tica da atração gravitacional (com contraposição ao conceito de deformação do tecido espaço-tempo), apresenta nova explicação do campo magnĂ©tico terrestre (com contraposição ao conceito de movimentos do manto terrestre), afirmando que somente o movimento de elĂ©trons Ă© capaz de gerar campos magnĂ©ticos (movimento de prĂłtons nĂŁo pode gerĂĄ-lo – um desafio que seja comprovado, ou nĂŁo), explica como se arranjam os campos magnĂ©ticos estelares, demonstra ser enganoso o conceito de BIG-BANG, eliminando a necessidade de energia escura, afirmando que o universo nĂŁo estĂĄ se expandindo e que, muito menos, o faz de modo acelerado. Conclui que sĂŁo excepcionalmente singulares as condiçÔes de vida no planeta Terra, sendo muitĂ­ssimo pouco provĂĄvel que possa existir vida assemelhada em outros planetas. Sugere que o melhor que se tem a fazer Ă© cuidar desse nosso planeta. Pedro Paulo Prado
