Anyone who has taken chemistry in high school knows that the elements that make up water are two hydrogen atoms and one oxygen atom. With a little electricity, we can split up the atoms, and voila!

The question of where atoms come from requires a lot of physics to be answered completely – and even then, physicists only have good guesses to explain how some atoms are formed.

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

It’s really simple… until it isn’t. Ahh, hydrogen—the simplest and most abundant element in the universe. Nearly three-quarters of the mass in the entire observable universe is believed to ...

H2O may be a renewable energy source, but the current hydrogen used to power hydrogen fuel cell vehicles is a nonrenewable natural gas that actually creates enormous CO2 emissions. It's a catch 22 ...
