"second most common element in the known universe " How about here on Earth? Since it doesn't chemically bond to other elements, the gas form escapes the atmosphere and is blown away by solar wind, effectively lost forever. All that we have is the byproduct of nuclear fission that is prevented from reaching the atmosphere by stratigraphic trap. It has that reservoir characteristic in common with natural gas, but as we know Carbon is much more reactive and goes through the carbon cycle. We could run out of Helium in any practical sense.
