What are the key takeaways from this The Infinite Monkey Cage episode?

Key insights include: **Cosmic Isolation:** In 100 billion years, accelerating universal expansion will push distant galaxies beyond light speed visibility, leaving future astronomers unable to detect evidence of expansion or past galaxies.; **Asteroid Detection Limits:** Earth receives 100 tons of space debris daily, but asteroids traveling straight toward us remain nearly impossible to detect against dark space until impact occurs at extreme speeds.; **Energy Waste Calculation:** Scientists can estimate power station requirements for specific wasteful practices by calculating population per facility, energy needed per unit, and scaling nationally to reveal systemic inefficiency.
