Are We Running Out of Space Above Earth?
Summary
This episode explores the growing threat of space debris and the potential for Kessler syndrome, a cascade of collisions that could render low Earth orbit unusable. It examines how orbital decay and tracking mitigate risks but highlights the dangers posed by untracked fragments and massive satellite constellations like Starlink. The discussion concludes with a lighthearted Q&A segment on Planck relics and their potential connection to dark matter.
