 * 1) <span style="color: #0f990f; font-family: Tahoma,Geneva,sans-serif;">75% of the universe's elemental mass is hydrogen
 * 2) <span style="color: #0f990f; font-family: Tahoma,Geneva,sans-serif;">Uncombined Hydrogen gas is so light it can actually escape the atmosphere (into outer space!!)
 * 3) <span style="color: #0f990f; font-family: Tahoma,Geneva,sans-serif;">Hydrogen gas is extremely flammable
