Episode notes
Ocean Floor Holes
- In 2022, NOAA discovered strange, rectangular holes on the Atlantic ocean floor.
- Similar holes were found in 2004, and fossilized rock, suggesting they aren't man-made.
Concrete Durability
- Roman concrete structures, some submerged in saltwater for millennia, remain standing.
- Modern concrete, however, has a shelf life of 50-150 years, posing environmental concerns due to its carbon footprint.
The Wow! Signal
- The "Wow!" signal, a strong, narrow-band radio signal detected in 1977, remains unexplained.
- Its frequency matches hydrogen's emission, leading some to speculate about extraterrestrial origins.
