The first elements to form at the beginning of the universe were 92% hydrogen and 8% helium, with the exception of a very small amount of lithium. The remaining elements were formed by stellar nucleosynthesis. That is, by the fusion of the stellar core, or by the heat of an explosion at the star’s death….
The ground rose up to form large bubbles. They have been called the “trembling tundra” because they jiggle when stepped upon. It turns out that these bubbles have formed because methane gasses are rising into the empty spaces created by melting permafrost. Like a ticking time bomb, the pressure is building up inside these bubbles…

You put some zinc into the hydrochloric acid in a test tube. The formation of hydrogen gas can be seen. That’s the chemistry you know. Zn + HCl → ZnCl2 + H2 In 1766, Henry Cavendish identified this element and named it hydrogen, which means water. The question of whether hydrogen began cooking in the…
