Re: If hydrogen wasn't the lightest element?

How could there be an element lighter than hydrogen? Elements are atoms -- nuclei of protons and neutrons orbited by electrons. A hydrogen nucleus is... one proton. Period. Since there are no free quarks, that's as light as a nucleus can possibly get. You might as well ask if it's possible to have a country with a population below one person. The only thing lower is zero.
