Stardust, Supernovae and the Molecules of Life: Might We All Be Aliens?

The place have been the amino acids, the molecules of lifestyles, created: possibly in a lightning hurricane within the early Earth, or even somewhere else within the cosmos? This ebook argues that no less than a few of them should have been produced within the cosmos, and that the truth that the Earthly amino acids have a particular handedness offers an enormous clue for that clarification. The ebook discusses a number of versions that purport to give an explanation for the handedness, finally presenting a brand new clarification that contains cosmic processing of the amino acids produced in area. The e-book presents a journey for laypersons that features a definition of lifestyles, the large Bang, stellar nucleosynthesis, the electromagnetic spectrum, molecules, and supernovae and the debris they produce.
