Is it theoretically possible to have a gas that's lighter than hydrogen?
Is it possible to create a material as light or lighter than hydrogen?
How is the element hydrogen created? Why is hydrogen so combustible? What would be the benefits if we discovered an element lighter than helium but it exists as a solid in room temperature? Any possible uses? How Hydrogen is used as a fuel? Can you make water by combining hydrogen and oxygen? How do they make a hydrogen bomb? If I built a laser using antihydrogen as the lasing medium, would I get the same wavelengths of light as if I'd used hydrogen? Why is Hydrogen combustible? What is 'metallic hydrogen'? What are light made of? What is light made of? Why can't we make water with hydrogen and oxygen? What is the industrial application of hydrogenation used for? How is light produced? How are hydrogen bombs made? How do you make liquid water from Hydrogen and Oxygen? Can I do it myself? Can I create a Hydrogen fuel cell without Platinum catalyst? What is light made out of? What exactly is light made of? Is hydrogen an element or an atom? Can we create some mass from energy? How can hydrogen be used as a fuel for automobiles? What is the product of burning hydrogen gas? What is light made up of? What obtains the element hydrogen? Hypothetically, what would be the ideal element or compound to convert into energy? Light is made of what? Water is made from hydrogen and oxygen, why doesn't it burn? Is reduction potential of hydrogen zero? Can dark matter form "atoms" in the classical sense, such as dark hydrogen or dark helium?
