hydrogen turned gas into stars far enough away to escape the black holes» gravitational pull.
Even though many of the planets orbit their stars very closely and have high temperatures, which in
turn causes their
hydrogen - rich atmospheres to expand and a fraction of the
gases to escape the planet over time, it's unlikely that the planets will lose enough of their atmosphere to become rocky bodies like Earth, the researchers report online today in the Monthly Notices of the Royal Astronomical Society.
Immense heat, pressure and magnetic fields ionise and contain the
gas,
turning it into a plasma in which
hydrogen nuclei fuse to form helium nuclei, releasing energy.

hydrogen gas which in
turn is used in the refining process for crude oil.
Presumably it has something to do with the fact that Jupiter is not really a «

hydrogen sulfide, the team cut off thin strips of the penis tissue and added a chemical that
turns into the
gas.
Under those conditions, reactions between the water and the rock would have liberated
hydrogen gas, which in
turn would have reacted with carbon dioxide, carbon monoxide, carbon grains or other carbonaceous material — producing methane.
Although atmospheric oxygen soon recovered again as photosynthesis and weathering reached a new balance, at about 10 per cent of present - day levels, the oxidative weathering of sulphides on land filled the oceans with sulphate which created abundant food for a group of bacteria that filled the oceans with sewer
gas (
hydrogen sulphide) toxic to oxygen - loving lifeforms (delaying the development of eukaryotic plants and animals) and
turned them «into stinking, stagnant waters almost entirely devoid of oxygen.»
Planets that are smaller (i.e. 1.5 Earth radii or less) or have less
hydrogen and helium early in their lives
turn into dense, rocky planets with solid surfaces, while larger planets or those with more
gas turn into Neptune - like planets with no discernable solid surface and thick atmospheres.
These shock waves, in

turning into extinction engines for fish and marine life, fresh water poisoning due to toxic algae blooms, oceans emitting increasing volumes of poisonous
hydrogen sulfide
gas into the air.
So unless there is a permanent, drastic, progressive and one - way alteration in the chemical makeup of the oceans over geological epochs (which would entail the massive evolution of
hydrogen gas and the production of oxygen, chlorine or
hydrogen peroxide) or a similarly huge increase in its potential energy (levitating it off the ocean floor), the energy involved will still have to be dissipated as heat (there's nowhere else for it to go, unless you get all science - fictiony and assume it vanishes into hyperspace or
turns into neutrinos or something).
