38 Places Where Nature Looks Straight Out of a Sci-Fi Movie

23. The Underwater Waterfall of Mauritius – A Mind-Bending Illusion

An underwater waterfall sounds impossible, right? Well, the island of Mauritius in the Indian Ocean is home to an optical illusion that makes it look like water is cascading down into the abyss. This jaw-dropping phenomenon is caused by sand and silt being pulled by ocean currents, creating an illusion that the seafloor is plunging into a deep, underwater void. From aerial views, it looks exactly like a giant waterfall sinking into the depths of the ocean, creating an effect that feels straight out of an intergalactic space-time rift. A place where gravity itself seems to bend and break? Definitely sci-fi-worthy.
