    Hydrogen is the most abundant element in the universe, making up 75% of normal matter by mass and over 90% by number of atoms.[6] This element is found in great abundance in stars and gas giant planets. Molecular clouds of H2 are associated with star formation. Hydrogen plays a vital role in powering stars through proton-proton reaction nuclear fusion.

    Throughout the universe, hydrogen is mostly found in the atomic and plasma states whose properties are quite different from molecular hydrogen. As a plasma, hydrogen's electron and proton are not bound together, resulting in very high electrical conductivity and high emissivity (producing the light from the sun and other stars). The charged particles are highly influenced by magnetic and electric fields. For example, in the solar wind they interact with the Earth's magnetosphere giving rise to Birkeland currents and the aurora. Hydrogen is found in the neutral atomic state in the Interstellar medium. The large amount of neutral hydrogen found in the damped Lyman-alpha systems is thought to dominate the cosmological baryonic density of the Universe up to redshift z=4.[7]

    Under ordinary conditions on Earth, elemental hydrogen exists as the diatomic gas, H2 (for data see table). However, hydrogen gas is very rare in the Earth's atmosphere (1 ppm by volume) because of its light weight, which enables it to escape from Earth's gravity more easily than heavier gases. Although H atoms and H2 molecules are abundant in interstellar space, they are difficult to generate, concentrate, and purify on Earth. Still, hydrogen is the third most abundant element on the Earth's surface.[8] Most of the Earth's hydrogen is in the form of chemical compounds such as hydrocarbons and water.[9] Hydrogen gas is produced by some bacteria and algae and is a natural component of flatus. Methane is a hydrogen source of increasing importance.

    This universe consists of mostly hydrogen. There's more hydrogen in this universe than any other form of matter combined. This is because this is the most likely element to form in the conditions after the big bang.

    We rarely find hydrogen on earth because it's very light, and very reactive. However, the sun (and most other stars) are consisted mostly of hydrogen.

    So to answer your equation, Stars of hydrogen in it.

    Because it is highly reactive hydrogen in nature is always combined with other elements. There are two atoms of hydrogen and one atom of oxygen in a molecule of water. hydrogen combines non metals to form acids like hydrochloric, and oxides of non metals to form other acids like sulfuric. It is a basic component of all organic matter, crude oil, etc. As others have said it is the most abundant element in the universe.

    Actually, after awhile, this can do more harm than good. Granted, using a toothpaste or whitening strip with hydrogen peroxide in it can work wonders because it is a small concentration of the compound and deeply cleans the teeth rather than bleaching the surface. However, gargling with straight peroxide will eventually dry out your teeth because of how powerful the chemical's cleansing is. It can lead to a condition known as decalcification which is basically the appearance of rather unattractive pale, creamy areas on the teeth. I wouldn't recommend using straight peroxide on a regular basis. Just once in awhile while you brush daily with a peroxide-based whitening toothpaste.
