Exploring the depths of the oceans is a challenging task due to their treacherous nature. Thankfully, advancements in technology, such as probes, SONAR, and hydrophones, have made it easier to study the deep sea. Hydrophones are particularly useful as they can convert underwater noises into electrical activity.

In 1997, hydrophones located in the Pacific Ocean picked up a highly unusual sound. This sound, known as the Bloop, is distinct and eerie, unlike any typical ocean noise. The National Ocean Service provides a recording of the Bloop, highlighting its strange and otherworldly quality. The origin of the sound was traced back to the ocean near Chile, but its extremely low frequency and mysterious nature left scientists baffled.

Contrary to popular belief, the Bloop was not caused by mythical creatures like the kraken or Godzilla, or even a fictional car backfire in Atlantis. Instead, researchers discovered a shocking but plausible explanation for this enigmatic disturbance.
