Daniel and Kelly’s Extraordinary Universe Do we live in a super bubble?
16 snips
Mar 17, 2026 A tour of the space between stars and where our solar system sits within it. They describe particle densities from Earth’s air to interstellar and intergalactic voids. Origins and contents of the interstellar medium, including gas, dust, cosmic rays and pre-solar grains, get attention. They explain bubbles carved by stellar winds and supernovae and what the Local Bubble around us means for the heliosphere.

Episode notes
Kelly's Gallbladder Surgery Affected Her Laughter
- Kelly recounts recent gallbladder surgery after painful gallstones that led to gallbladder removal.
- She explains stitches make laughing painful and mentions adjusting her laugh during the episode.
Daniel's Little Toe Break Taught Him About Pain
- Daniel shares minor injuries: a broken wrist that didn't hurt much and a painfully stubbed little toe that felt severe.
- He humorously notes standard treatment is taping the toe to its neighbor rather than surgery.
Space Is Extremely Low Density Compared To Earth
- Interplanetary and interstellar space are far emptier than Earth's atmosphere but still contain millions of particles per cubic meter.
- Daniel contrasts Earth (~10^25 molecules/m^3), lab vacuums (~10^12–10^15), and solar wind (~10^7 protons/m^3) to show scale.
