Unbelievable Facts about World History that will surprise you

Human history and the natural world are filled with mysteries, marvels, and strange truths that challenge our understanding of the past, present, and even the structure of time itself. History is often seen as a series of well-recorded events, but behind the textbooks lie astonishing facts, bizarre mysteries, and mind-blowing stories that challenge what we think we know about the world. From ancient technologies to forgotten civilizations, the world’s past is filled with surprises that continue to puzzle historians, amaze scientists, and ignite curiosity in all of us.

1 Marine fossils are found at the top of the Everest

Everest's peak was once part of the Tethys Sea. Tectonic plate collision pushed ocean floor rocks, along with marine fossils, to Earth's highest point.

• Everest was once underwater. The peak of Mount Everest was part of the Tethys Sea millions of years ago, before the Himalayan mountains were formed. The summit of Mount Everest is made up of marine limestone, which means the highest point of Earth was once under water.

• The rocks that make up Mount Everest were formerly at the bottom of an ancient ocean known as the Tethys Sea, and marine fossils can be found at the top of the mountain. The ocean floor was forced upwards by a collision between the Indian and Eurasian tectonic plates millions of years ago.Shells and other marine fossils were carried to the highest peak of the Himalayas by this enormous collision.

2 Nuclear weapon technology was used before in ancient times

Ancient texts like the Mahabharata describe weapons with immense power, often compared to nuclear blasts. While intriguing, mainstream archaeology does not support these claims.

• Mythological references: Ancient Indian texts like the Mahabharata and Bhagavad Gita describe weapons (like the Brahmastra) with destructive powers that some interpret as resembling nuclear explosions.

• Mohenjo-Daro theory: Some fringe theorists claim high radiation levels and mysterious destruction at Mohenjo-Daro point to a nuclear blast, but archaeologists deny this.

3 Tartaria: The Lost Empire and the Mud Flood Conspiracy

Tartaria, shown in old maps, is believed by some to be a lost advanced civilization erased by global powers. The mud flood conspiracy suggests history may have been altered to hide its legacy.

• Tartaria (or Tartary) appeared on many ancient and medieval European maps, especially from the 16th to 19th centuries. A series of mudslides, commonly known as "mud floods," are said to have destroyed the majority of the empire. History was rewritten to make buildings appear younger and more contemporary, and the empire was purposefully erased, according to the conspiracy.

• Some online theorists believe Tartaria was a highly advanced global civilization that was intentionally erased from history. It is said that the Tartareans possessed free energy, advanced architecture, and an energy source that was so powerful it threatened modern structures; hence, all evidence of it was destroyed.

4 A Temple That Has No Shadow at Noon

The Brihadeeswarar Temple in India is a marvel of solar alignment; despite its massive size, it casts no shadow at noon, showcasing ancient architectural brilliance.

• The Brihadeeswarar Temple in Tamil Nadu was built over 1,000 years ago.

• Despite its height (66 meters), it casts no shadow at noon due to architectural brilliance and solar alignment.

5 There is a “Door to Hell” That has Been Burning for 50+ Years

In Turkmenistan, a gas crater ignited in 1971 continues to burn today. Known as the Darvaza Gas Crater, it is a fiery reminder of human interaction with nature gone unpredictably wrong.

• In Turkmenistan, a gas drilling mishap in 1971 led to the collapse of an underground cavern. To prevent methane leaks, scientists ignited it, expecting it to burn out in a few days.

• It is still burning today, now known as the Darvaza Gas Crater.

6 The one region of the Great Wall of China was built towards Tartaria

The Great Wall of China’s northern orientation, once guarding against Central Asian invasions, has led some to tie it to Tartaria. While the name Tartaria is controversial, the direction of the wall reflects real historical threats.

• The one region of the Great Wall of China was strategically built towards the north (Tartaria region) to defend against powerful nomadic tribes from Central Asia, not because of Tartaria itself, but the people and threats that came from that direction. The Wall has been rebuilt many times in so many years, but even today, the oldest part of the wall faces not the Chinese road but the Tartaria road. This indicates that this wall was built to protect Tartaria.

A restaurant where you are never served with the right order

Located in Japan, this restaurant employs people with dementia. Guests may receive the wrong meal, but that’s part of the experience, highlighting empathy, patience, and social acceptance.

• There is a restaurant in Japan called The Restaurant of Mistaken Orders. Customers may not always get what they ordered here because the servers suffer from dementia. The idea is to raise awareness and understanding of dementia in a respectful, light-hearted way. Mistakes are part of the experience, encouraging empathy and acceptance. It is not just about food, but about kindness and accepting flaws.

8 There is a Calendar of 13 Months

Proposed in 1902, the International Fixed Calendar aimed to bring consistency to timekeeping. With 13 equal months of 28 days and extra "off-calendar" days, it never gained wide adoption but remains a fascinating concept.

• The International Fixed Calendar divides the year into 13 months, each having exactly 28 days (4 weeks). The extra month is called "Sol" and is usually inserted between June and July.

• This makes a year 364 days, with 1 or 2 extra days (year-end holidays) not part of any week or month to match the solar year (365 or 366 days).

These stories, whether rooted in science, conspiracy, or compassion, reflect the diversity of human thought and experience. Some, like marine fossils on Everest, have strong scientific backing. Others, like Tartaria or ancient nuclear warfare, live in the realm of mystery and alternative theory. What unites them all is the curiosity they inspire, reminding us to question, explore, and remain open to the wonder of our world.

Whether you're fascinated by forgotten civilizations, natural anomalies, or acts of human kindness, these facts show that reality is often stranger and more beautiful than fiction.
