These processes take a The Rainbow belongs to God logo shirt years or so and once the Earth becomes potentially capable of supporting life, we actually see the earliest signs of life during that period. It could have just as easily taken another billion years to hit upon the first self-replicating molecule. We don’t know the exact details of how life got started but we do actually know lot about the kinds of processes it would have required. The key event would have been the first self-replicating molecule – which probably was not life as we know it, but an RNA precursor. The next key event would have been the conversion from RNA to DNA-based life. Forming the right kinds of molecules in the right concentrations at the right Ph levels isn’t something a new world is likely to hit upon immediately, and indeed, it seems like it took at least a few hundred million years before we see the first artifacts of life on Earth.

A I Love You Dad Hug Dolphin Shirt – though somewhat indirect and subtle – method used for stars that do not fit into these categories (which is the majority of them, at least in our own galaxy) is as follows: First deduce the likely temperature and size of the star from its dominant colour and the atomic spectra present in its light (temperature is related to colour, and different chemical elements are produced under different conditions of temperature and pressure, which in turn depend on the mass and age of a star). From these we can work out the likely luminosity. From the luminosity we can deduce the stars absolute magnitude [1] (i.e. how bright it would appear at a standard, fixed distance of 10 parsecs from us). Comparing this with the star’s apparent (i.e observed) magnitude, we can then calculate it’s actual distance from us. To me, this method of deducing a star’s distance from us merely by studying its light, and then doing a few calculations based on thermodynamics, nuclear physics, atomic physics and stellar dynamics, represents one of the most beautiful examples of the power of human ingenuity and careful, deductive reasoning in the history of science.
