Light From Chemistry

September 24, 2025  •  EPISODE 279

What is chemiluminescence? It’s the process of producing light through chemistry—no electricity required. In this episode of Science LIVE, Dr. Roger Billings explains how chemical reactions can generate light, from fireflies and glowing oceans to everyday glow sticks. Explore the science behind these luminous phenomena and discover how nature and technology both harness the power of chemiluminescence.

    Is it the same chemical in all the creatures that produce bioluminescence? Or are they all different chemicals in each of the creatures?

    Is the hydrogen rift a fault line and do we have to worry about it breaking apart?

    There is enough hydrogen seeping up from the Earth to supply the world with energy for many years, however, scientists are trying to find better ways to actually access this hydrogen.

    We have lightening bugs at our house but not many. My mom said she use to catch them and put them in jars for a while then she would turn them loose when my nannie made them come inside.

Your video about fireflies brought back memories of summer nights spent outside my house with my family, enjoying the simple beauty of life—just like the glow of a firefly.

    I liked Dr. John’s lesson on the phenomenon ‘fairy circles’ and what they exactly are. I’ve never heard of these ‘fairy circles’ but I’m glad I have now! It’s amazing that researchers have found that the circles are created from hydrogen seeping through the soil and that there is a bigger source of reoccurring hydrogen in a similar way from the circles in the Mid-Continental Rift that almost split the continent in two! It’s so interesting that the earth can create all the necessary gasses and provide enough resources for both life and the planet itself to sustain changes. My theory is going to be similar to the ones mentioned, I believe that the hydrogen is being created down inside the earth from friction and is rising through the crack of the rift. I loved Mr. Billings lesson on the insight of Acellus from public schools, Algae that creates light, where Pajet is from, and Elon Musk’s satellites. I really enjoyed the lesson on the one-cell algae that uses chemical reactions to create light to fend off predators. I especially loved when you were able to create the actual light using hydrogen peroxide and a ‘magic chemical’, that was so incredible! I can’t believe you were able to simulate it! I also enjoyed the lesson on Fireflies and how their biology for their lights is similar to the algae. It is amazing to hear that R-51 has found where Pajet comes from, maybe he can attempt to make contact on the planet and see if there are any more Pajet’s there? I do have a question, since you mentioned Elon Musk’s satellites he put up a few years ago, do you think that Elon could ever create the technology for flying cars?

    Question on the Fireflies:

    Question for the “Fairies”:
    These Hydrogen spots that were talked about, Do you think these could pontentialy lead to fuel for rockets?

    I’m very curious on rocket science, and would love to hear about the principles of propulsion, thrust, and aerodynamics. Thanks!
