Why Is Space Cold If There Are So Many Stars?
Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning...

Why Is It Called "Dead" Sea? Why Does Everyone Float In This Sea?
Lying on the lowest point on the Earth, the hypersaline Dead Sea is one of the most fascinating places on this planet. People float effortlessly here and that is the major attraction of the Dead Sea. But besides this natural buoyancy,...

Why Do Tightrope Walkers Carry Long Poles when Walking on A Rope?
Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...

Why Do Space Photos Look Like There Are No Stars?
Although stars are visible in space, pictures of celestial bodies taken from satellites by astronauts do not show any stars in the background. This is because the stars are very far away and, therefore, appear incredibly dim in contrast...

Why Do Humans Have Fingernails And Toenails?
Human fingernails are actually flattened versions of claws. All primates, including ancient ancestors of humans, had claws that supported their broad fingertips. The broad fingertips helped primates maintain a strong grip around objects,...

Why Do Babies (Toddlers) Hand You Things?
Toddlers like handing people things as part of developing schemas, patterns of repeated actions that build cognitive skills. Giving objects helps toddlers learn the transportation schema, which involves moving items from one place to...

Why Are Fingers Different Lengths?
Humans do not have equal finger lengths due to the evolutionary advantage it provided our ancestors in gripping and manipulating tools. Around 3 million years ago, our ancestors started using stone tools, which became more refined over...

What Would Happen If You Traveled At The Speed of Light?
If you travel at the speed of light, your mass will increase exponentially. The speed of light is 300,000 kilometers per second (186,000 miles per second). When you move at this speed, your mass will become infinite. Therefore, infinite...

What is the Heisenberg Uncertainty Principle: Explained in Simple Words
Heisenbergs uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...

Archimedes Principle: Explained in Really Simple Words
Archimedes principle states that if an object is submerged in a fluid, then the buoyant force acting on it is equal to the weight of the fluid displaced by that object. Buoyant force exists because pressure increases as an object goes...
