Debunking Myth: Do bananas and humans share 60% of their genes?
Yes, humans and bananas share about “60% of their basic DNA building blocks.
How many more Pluto-like dwarf planets are in our solar system?
Our solar system likely contains hundreds of Pluto-like worlds—and possibly hundreds of thousands more far beyond Pluto itself.
Does time travel exist?
Physics allows time to bend forward, but all observations so far show that causality is preserved.
Does my gravity pull on the Sun?
Gravity is universal: every mass influences every other mass, no matter how small.

What is the farthest object in space?
The farthest thing we can observe isn’t an object at all, but the universe’s oldest light. The Cosmic Microwave Background.
Can you explain quantum tunneling simply?
Quantum tunneling happens when a particle is found beyond an energy barrier it should not cross under classical physics.
What is the classic double‐slit experiment?
The double-slit experiment shows why quantum mechanics is so strange: tiny things land like particles, but their overall pattern can form like waves.
