But when they look at the stars, they turn emotional and believe that if aliens exist, they must be friendly and kind.I think it should be the opposite: Let’s turn the kindness we show toward the stars to mankind and build up trust and understanding between different peoples and ...
Without stars, we would simply not exist. These cosmic behemoths use nuclear fusion to produce the elements that planetary systems and living beings are made of (carbon, oxygen, iron, etc.). The next sections will describe this process by outlining the different stages in the life cycles of...
