The two most common things in the universe are hydrogen and stupidity. (Religion & Universe & Hydrogen & Stupidity) Robert G Ingersoll
His [Cavendish] discovery in 1766 of one of the most important elements in the universe ... Cavendish had discovered hydrogen. Genius of Britain II: A Roomful of Brilliant Minds, Channel 4 2010
A few minutes were all Gamov needed. In that time all the hydrogen and almost all the helium was made. That’s about 98% of all the atoms in the universe today. Or as Gamov put it, our universe was cooked in less time than it takes to cook a dish of duck and roast potatoes. Professor Jim Al-Khalili, Atom: The Key to the Cosmos, BBC 2010
Hydrogen is the most abundant element in the universe. Order and Disorder with Jim Al-Khalili I: Energy, BBC 2012
The same nuclear reactions that take place in a hydrogen bomb – converting hydrogen into helium – produces the energy that causes stars to shine. Universe: Stars
Sun: A colossal nuclear reactor comprised of three-quarters hydrogen – the rest mostly helium with traces of heavier elements ... This process called Fusion gives off radiant energy. The Universe s5e8: Dark Future of Our Sun, History 2010
When a star runs out of hydrogen it begins to die. But it doesn’t go quietly. Rather than cooling, the star becomes much hotter until there is a sudden flash, then the star starts to expand ... As it cools it takes on the characteristics of a dying star. It becomes a Red Giant. Brian Cox, Wonders of the Universe 2/4: Stardust, BBC 2011
The core will start to collapse very rapidly leaving a shell, leaving hydrogen and helium behind ... The creation process of Carbon and Oxygen is over in the blink of an eye. ibid.
The fusion of hydrogen into helium is the foundation of all the sun’s power. Brian Cox: Wonders of the Solar System, BBC 2010
A helium atom weighs a little bit less than four hydrogen atoms. And if you use Einstein’s good old formula E = MC² that means you get a whole lot of energy for just that little bit of mass. (Sun & Hydrogen & Helium & Energy & Nuclear) Professor Harold Zirin
The Sun shines by nuclear fusion: the fusion of four hydrogens into one helium. First one hydrogen fuses to another, then another, then a fourth. Helium weighs less than the four hydrogens that went into making it. What you get out is less than what you put in. That mass difference is energy that powers the Sun. Ken Lang, author
Eddington suggested that the sun shines by combining hydrogen into helium, releasing the missing mass as energy. Horizon: Can We Make a Star on Earth? BBC 2009
It will run out of hydrogen fuel in its core. ibid.
A red giant is a star that has exhausted its primary reservoir of hydrogen fuel at its core. ibid.
Hydrogen is a much tougher alternative fuel than any other alternative fuel we’ve ever pursued. Joseph J Romm, author The Hype About Hydrogen
About five billion years from now it will come to the end of its hydrogen fuel ... An expanding vermilion Sun. A red giant of hot gasses pushing out into space. Solar Empire: A Star is Born, Discovery 1999
About 90% of all the atoms in the universe are hydrogen. Nova: Hunting the Elements II, PBS 2012
There is more stupidity than hydrogen in the universe, and it has a longer shelf life. Frank Zappa
The environmental benefits of hydrogen are also outstanding. When used as an energy source, hydrogen produces no emissions besides water. Zero polluting emissions, an amazing advance over the current sources of energy that we use. Dan Lipinski
If we had a hydrogen economy worldwide, every nation on earth could create its own energy source to support its economy, and the threat of war over diminishing resources would just evaporate. Dennis Weaver
But in the heavens we discover by their light, and by their light alone, stars so distant from each other that no material thing can ever have passed from one to another; and yet this light, which is to us the sole evidence of the existence of these distant worlds, tells us also that each of them is built up of molecules of the same kinds as those which we find on earth. A molecule of hydrogen, for example, whether in Sirius or in Arcturus, executes its vibrations in precisely the same time. Each molecule, therefore, throughout the universe, bears impressed on it the stamp of a metric system as distinctly as does the metre of the Archives at Paris, or the double royal cubit of the Temple of Karnac ... The exact quantity of each molecule to all others of same kind gives it, as Sir John Herschel has well said, the essential character of a manufactured article and precludes the idea of its being external and self-existent. James Clerk Maxwell
It has been recognized that hydrogen bonds restrain protein molecules to their native configurations, and I believe that as the methods of structural chemistry are further applied to physiological problems it will be found that the significance of the hydrogen bond for physiology is greater than that of any other single structural feature. Linus Pauling, Nature of the Chemical Bond and the Structure of Molecules and Crystals 1939
