8 Simple Questions About Our World We STILL Can't Answer In this intriguing YouTube video titled "8 Simple Questions About Our World We STILL Can't Answer," the host dives into some of the many mysteries our planet still holds despite extensive scientific progress. Here’s a detailed breakdown of the eight questions explored in the video.
1. Unexplored Caves
The video opens by highlighting that over
95% of our oceans remain unexplored, and it turns out thousands of caves on land also await discovery. National Geographic estimates that as much as
90% of caves worldwide remain untouched, even in well-explored areas like the United States.
2. Unknown Minerals
There are about
5,000 known minerals on Earth, but estimates suggest there may be over
1,500 unknown minerals that haven't been documented due to limited exploration and access to various terrains. This figure could increase substantially if we consider minerals that aren't easily obtainable.
3. What Lies Beneath
Despite some geological theories, we understand very little about what lies beneath Earth's crust. The
Kola Superdeep Borehole—only
7.5 miles deep—gives us some insight, but many questions remain about the
Earth's core and the possibility of unknown oceans existing deep within.
4. Undiscovered Civilizations
The video posits that countless ancient civilizations may still be hidden beneath vegetation or underwater. Advancements in methods like
ground-penetrating radar have led scientists to discover new ancient structures, suggesting that we are only scratching the surface of our historical knowledge.
5. Known Species
With millions of species on Earth, we've only accounted for about
1.2 to 1.3 million of them, leaving an estimated
90% still unknown. A striking example is the
30-year study of a garden in England, which unearthed over
8,000 species, including previously unseen types.
6. The Nature of Gravity
Gravity remains one of science's biggest enigmas. While it governs movement within the universe, we still don’t fully understand what it is or how it operates on a fundamental level, sparking debates and theories that challenge conventional viewpoints.
7. Slippery Ice
The reason ice is slippery is still not completely understood. Although it’s acknowledged that a thin layer of water forms on ice surfaces, the mechanisms behind this phenomenon, including pressure and friction theories, remain speculative.
8. The Creation of the Moon
Several theories exist concerning how the Moon was formed, ranging from collisions with Earth to being spun off from our planet, yet no consensus has been reached within the scientific community.
Conclusion
This video refreshingly reminds us that, despite advances in technology and science, many questions about our world remain unanswered. This sense of mystery can be invigorating and encourages curiosity about our surroundings. Feel free to share your thoughts and any related experiences in the comments!
