Frequently Asked Questions
Why is the universe mostly empty space?
The universe is primarily composed of vast expanses of empty space due to the low density of matter. Most of the universe's mass is concentrated in stars, galaxies, and dark matter, leaving large voids in between.
What percentage of our DNA is identical to that of a banana?
Humans share about 60% of their DNA with bananas, highlighting the fundamental similarities in the genetic makeup of all living organisms.
How much of our brain do we actually use?
The myth that we only use 10% of our brain is false. Neuroimaging studies show that we use virtually every part of our brain, and most of it is active almost all the time.
What is the paradox of time travel?
The paradox of time travel involves scenarios like the grandfather paradox, where a time traveler could potentially prevent their own existence by altering past events, raising questions about causality and the nature of time.
