Explosões de raios gama podem ter dizimado civilizações extraterrestres, diz astrônomo

Um cientista revelou uma possível razão pela qual os humanos ainda não foram contatados por alienígenas: suas civilizações podem ter sido destruídas por explosões de raios gama (GRBs).

GRBs são eventos imensamente poderosos observados em galáxias distantes, ocorrendo durante a formação de buracos negros, quando o núcleo de uma estrela massiva entra em colapso sob sua própria gravidade, desencadeando um enorme jato de radiação.

“É um feixe de energia bastante concentrado”, afirmou o professor de astronomia Dr. Frederick Walter em entrevista ao jornal britânico Daily Mail.

“E, se for direcionado através do plano da galáxia, poderia basicamente aniquilar cerca de 10 por cento dos planetas. Porém, é apenas uma das diversas explicações plausíveis. Um pouco mórbido, creio”, admitiu o especialista.

A NASA descreve os GRBs como “a classe mais poderosa de explosões no universo”.

Embora tais fenômenos possam ser apocalípticos, o Dr. Walter esclareceu que qualquer ameaça potencial à humanidade “não merece preocupações” excessivas.

“Eles são raros e são direcionados, o que os torna muito menos propensos a atingir a Terra. E não é algo para o qual você possa se preparar”, explicou o astrônomo.
