Many of us have somehow romanticized life in castles with all the feasts, beautiful outfits, lords, and ladies. But medieval life was as far from the glamorous picture in your head as possible! Narrow passageways, smoky fires, gloomy and dark rooms - that's what would have greeted you upon setting foot in a castle in medieval times. And that’s just the good part...

The Megalodon was the biggest shark to ever live and the largest predator in Earth's history. It could swallow a small car without it even touching its teeth - if cars had been around then. Scientists believe the Megalodon didn't look like a white shark: the ancestors of today's Great White existed at the same time as the Meg. Only around 80% of the ocean has been explored, so who knows what's lurking at the bottom? The Kraken, a colossal squid with powerful tentacles, could be hiding there along with the Meg.

What's the most isolated spot on Earth? Have you ever heard about Point Nemo? It's the most remote place on our planet. The name says it all — “Nemo” means “no one” in Latin. This loneliest of lonely spots is more than 1,600 miles from any coast. Below: tens of thousands of feet of oceanic depths. Above: endless skies. A place that occupies 10% of the world’s oceans. A place that’s called a “desert” because of the almost complete absence of life. So if you're tired of your problems and want to run away from all the nervous hassle, Point Nemo is exactly what you need! But don’t expect too much solitude because somebody’s already living there...

What animal has the most babies at one time? When it comes to biology, any species’ primary goal is to perpetuate itself. Our own species usually makes just 1 successor at a time, while a queen ant can make thousands a day. That’s far from the maximum, but let’s start small on roughly how many offspring this planet’s animals can have… For example, elephants, giraffes, camels, zebras, and humans typically have a single youngling at a time. African wild dog has a litter of two to 20 pups. Salamanders lay up about 300 eggs at a time. Piranha lays about 5,000 eggs in the nest. But there are creatures that lay up millions of eggs at once!

Let's take a fascinating linguistic journey back in time to discover the oldest languages known to humankind! Deep within the annals of history, we find languages like Sumerian, dating back to around 4,000 BCE, spoken in ancient Mesopotamia. Then there's Egyptian, with its mysterious hieroglyphs, originating around 3,200 BCE, captivating us with tales of pharaohs and pyramids. Traveling eastward, we encounter Tamil, a Dravidian language spoken in South India, boasting a rich history dating back over 2,200 years.

Picture in your mind, you’re camping with your buddies for the weekend in a nearby forest. Your tents are all set-up, you ate your dinner, and you went to sleep. Suddenly, the smell of smoke wakes you up. You go outside to see what’s going on, and there it is: you’re in the middle of a wildfire. This scenario might seem unreal for most people, but it’s more common than you’d expect. Wildfires are very fast; they can overtake the average person in just a few minutes. Their flames travel approximately 14 miles per hour, and they burn everything in their path if they find enough fuel to feed on. Knowing what’s going on and how to act in these situations is a true life-saver.

Would you like to spend an entire week digging in the ground, scanning for ruins, and taking photographs of the world's most surreal archeological sites? The Roman Emperor Nero ordered to build the magnificent Domus Aurea back in 64 BCE. In its glory days, it occupied an area three times the size of the Vatican City. After flying halfway across the world, you're deep in the Cambodian jungle admiring the beauty of the city of Angkor. If you like terracotta landscapes, you should visit the city of Petra, which was a commercial hub back in the 4th Century BCE.

Did you know that the music you're listening to at the moment affects your heartbeat?

What happens underwater during a hurricane? How do hurricanes affect sea life? Where do fish go? People normally snap to attention and take shelter as a storm approaches land, but the storms spend most of their time out at sea. So when a hurricane hits, what happens to sharks, dolphins, and other sea creatures? Well, some animals, such as sharks and other fast swimmers, are generally in the clear. Sharks even have organs that allow them to detect the changes in barometric pressure accompanying severe storms. Dolphins are another large aquatic species able to sense approaching storms. But what is it that has the kings of the ocean swimming scared?

Some lakes in the world seem peaceful and beautiful, but in fact, they're hiding some dangerous secrets. Lake Monoun in West Province, Cameroon, seems calm but is one of the few erupting lakes on the whole planet – similar to a volcano. Natron Lake in Tanzania may be beautiful to watch because of its unique reddish coloring, but it's definitely not a place you'd want to take a swim in. It has pH levels so high that they become corrosive, so if you dampen a piece of dyed material in this lake, it will soon be stripped of its color. Let's explore some other mysterious lakes on our planet that aren't what they really seem.

Scientists think it took 3.5 billion years for us to evolve from single-celled organisms into our present state. If true, this means we are still mutating and evolving today. And we could, potentially, evolve in any direction. Maybe we’ll develop flight? Or transparency! But what if some of our older genes re-emerged? Could we devolve into something closer to the ape-like form of every primate’s common ancestor?
