Deep in the ocean’s twilight zone, scientists have discovered a strange, low-frequency hum—and no one knows exactly what’s causing it. 🌊🐠 This mysterious sound pulses through the water, and it happens every day, right around sunrise and sunset. Some experts think it might be millions of tiny sea creatures moving up and down in the water, like a giant underwater migration. Others believe it could be linked to ocean currents or even unknown marine life communicating in ways we don’t yet understand. Whatever the cause, this eerie hum is unlike anything we’ve ever heard before! Maybe solving this mystery will unlock secrets about the deep sea that we never imagined. 🌊🔍 Credit: diel migration: By NASA, https://commons.wikimedia.org/w/index.php?curid=95495286 Planet Earth III / BBC Studios OBS deployment: By John Whitehead – Ocean Instruments, https://commons.wikimedia.org/w/index.php?curid=15663716 Utah Rainbow Arch: By BoNoMoJo, CC BY-SA 3.0 https://creativecommons.org/licenses/by-sa/3.0/, https://commons.wikimedia.org/w/index.php?curid=63124 Hydrophone: By Dave Mellinger/Oregon State University – https://flic.kr/p/6p1CyK, CC BY-SA 2.0 https://creativecommons.org/licenses/by-sa/2.0, https://commons.wikimedia.org/w/index.php?curid=48583320 Underwater-microphone hg: By Hannes Grobe/Alfred Wegener Institute for Polar and Marine Research, CC BY-SA 2.5 https://creativecommons.org/licenses/by-sa/2.5, https://commons.wikimedia.org/w/index.php?curid=2284981 Animation is created by Bright Side. —————————————————————————————- Music from TheSoul Sound: https://thesoul-sound.com/ Check our Bright Side podcast on Spotify and leave a positive review! https://open.spotify.com/show/0hUkPxD34jRLrMrJux4VxV Subscribe to Bright Side: https://goo.gl/rQTJZz —————————————————————————————- Our Social Media: Facebook: https://www.facebook.com/brightside Instagram: https://www.instagram.com/brightside.official TikTok: https://www.tiktok.com/@brightside.official?lang=en Telegram: https://t.me/bright_side_official Stock materials (photos, footages and other): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru —————————————————————————————- For more videos and articles visit: http://www.brightside.me —————————————————————————————- This video is made for entertainment purposes.
