5 places science can't explain

There are still some places in the world that defy explanation, logic and experiments, and while we're not saying these are proof that aliens exist, we're still fascinated by them.

1. The Fairy Circles Of Namibia

What you're looking at in the image above is a field of grass frequently interrupted by circular patches where nothing will grow.

The circles range between 10 to 65 feet in diameter and go on for over a thousand miles. Scientists have remained stumped as to what causes it. Not only can they not explain what makes the circles, they can't even crack the most basic questions, like why they're more or less evenly spaced, why they're always circular, why they never overlap, or like, what even is a circle, man?

2. The Taos Hum

For residents of Taos, New Mexico, humming is a constant thing. Since the 1990s, residents of Taos have reported a constant, ceaseless humming noise that permeates the entire town and drives them close to barely distinguishable madness.

Investigators have been attempting to locate the source of the maddening sound for over 20 years, with no success.

3. The Devil's Kettle In Minnesota

At some point along the Brule River, the river flow splits along a rock outcrop. Half of it continues flowing on to Lake Superior, and the other half falls down a hole to nowhere.

The assumption has always been that it flows through a system of underground caves until it pops out again somewhere near the lake because it has to wind up somewhere. But scientists have never figured out where that is.

4. The Hessdalen Lights

Locals of the Hessdalen Valley in Norway have been witnessing streaks of light night after night. Strange lights appear in the sky, dance around in patterns, and even flash in different colours. Science confirms the Hessdalen Lights are a real thing, and they don't know what causes them.
