7 Places on Earth That Don't Seem Scientifically Possible

The world is filled with amazing places to visit, but some of them are actually quite odd. Yet other places are so strange that they seem to defy all reason. 

Here we highlight 7 of these very peculiar locations and offer the most recent explanations for their weirdness.

Which is the strangest place in the world?

There are many interesting, and strange places around the world. Many of them seem to defy logic, but for some reason or other, they exist nonetheless.

According to sites like Lonely Planet, here are some of the strangest places around the world that might be worth a visit: 

• Crooked Forest in Poland
• Salt flats of Uyuni in Bolivia
• Eye of the Sahara in Mauritania
• Snake Island in Brazil
• Stonehenge in England
• Bermuda Triangle
• Cave of the Crystals in Mexico
• Nazca lines in Peru

What are some examples of places that seem to be scientifically impossible?

So, without further ado, here are 7 of the world's oddest places that seem to defy science. Trust us when we say this list is far from exhaustive and is in no particular order.

1. This volcano's lava is actually blue!

Kawah Ljen, is an interesting seemingly science-defying volcano in Indonesia that produces a weird blue colored lava from time to time. This phenomenon is so unexpected that it really needs to be seen to be believed.

But the lava isn't really lava, it's actually sulfur. Sulfuric gases heat up inside the volcano, burst out of it and ignite -- sometimes up to 5 meters into the air!

These hot, burning gases eventually cool and condense into liquid sulfur which spill down the volcano's slopes forming the iconic neon-blue "lava" flows. 

2. This double tree isn't something you see every day

This doubletree in Casorzo, Piemonte, Italy is another interesting place that doesn't seem possible. Called the "Doubletree of Casorzo", it consists of a perfectly healthy-looking cherry tree that can be found growing out of an older mulberry tree!

This kind of event is not unprecedented, however. Parasitic trees have been observed before but these are normally stunted, small trees that don't tend to live for very long. 

What is incredible about this example is that it consists of two fully-formed healthy trees. It is not known for sure how this happened, but locals believe a bird dropped a cherry seed on top of the mulberry tree at some point. 

The seed's roots were then able to push through the mulberry tree's hollow trunk to eventually find purchase in the soil below. 

3. This well turns things into stone

A well in Knaresborough in North Yorkshire, England, is another interesting place that seems to defy science. Here, water trickles down a cliffside forming what looks like a skeleton's grinning face!

What's more, anything that is placed under the water will eventually be turned to stone. The petrifying process usually takes between three and five months and is an interesting way to create some novelty keepsakes.

Visitors have left many different things there to be turned to stone including teddy bears and bicycles. The well was believed to be cursed by a witch for many centuries in the past. 

Today, however, it has been determined that the waters have a higher than normal mineral content. Because of this, anything that contacts the water is slowly coated in a hard mineral shell over time.

This is exactly the same process that forms stalactites and stalagmites in caves. 

4. Movile Cave is a very strange place indeed

Movile Cave in south-eastern Romania is one of the world's strangest places. The cave has been sealed from the rest of the world for somewhere in the order of 5.5 million years.

Not only that, but its atmosphere is like nowhere that can be seen anywhere else on the planet. Thanks to a lake of sulphuric water that stinks of eggs, the air in the cave is filled with hydrogen sulfide and carbon dioxide around 100 times the concentration of the Earth's atmosphere.

Despite the air being incredibly toxic to most living things on the surface, the cave is far from devoid of life. Incredibly a highly-specialized ecosystem has not only survived down there but is thriving.

To date, around 33 different species have been identified in the cave that does not exist anywhere else on the planet. These critters have adapted to survive in the sulphuric atmosphere with the food chain based on a floating mat of extremophile bacteria.

5. Have you heard about the amazing lightning storms in Venezuela?

"The Beacon of Maracaibo" is another place on Earth that appears to be scientifically impossible. Located in Western Venezuela over the Catatumbo River, you can actually find a lighting storm that seemingly never ends.

Each storm starts around 7 pm every evening and lasts for about 10 hours a night. This amazing lightning show can be seen every night for around 260 days of the year.

The storms are most prominent during the wet season in October and tend to ease off in January and February of each year.

Nobody can really explain why this happens, but theories in the past believed it might have something to do with the uranium-rich bedrock of the region. 

"Today, the leading theory is a complicated one. It posits that the shape of the mountains causes warm trade winds to collide with cold air from the Andes. That collision is then fueled by the rapidly evaporating water below and methane from a nearby oil field." - listverse.com. 

6. This glacier looks like its bleeding

"Blood Falls" in Antarctica is yet another strange place on Earth that appears to defy science. The blood-red waterfall is around five-stories tall and pours out of the Taylor Glacier in Antarctica's McMurdo Dry Valleys.

The falls were first found in 1911 by a team of geologists who initially thought the color might be derived from a  form of algae. 

But the reality is far more incredible. Around 2 million years ago, the glacier sealed beneath it a small body of water. 

Isolated from the rest of the world, microbes in the water evolved independently increasing the salinity and iron content of the sealed-off water. More recently a fissure opened up in the glacial cap, allowing the subglacial lake to flow out forming the characteristic falls we see today. 

7. This boiling river doesn't seem possible

Located deep within the Amazon is a river called Shanay-Timpishka. The river is about four miles long (6.4 km) is like no other river on Earth.

The river is incredibly hot and nothing can survive entering its waters without being boiled alive. Temperatures of the river have been recorded to be as much as 91 degrees Celsius. 

Interestingly, scientists are not entirely sure why this lake is so hot. Ordinarily water this hot tends to be fed by a volcano but the nearest one is around 700 km away.

There are some theories that the waters come from deep within the Earth's crust but no-one knows for sure.
