Answer:

Humans have made a staggering amount of scientific and technological progress over the past century. We’ve created technology that has transformed our society; scientific advances have helped us answer fundamental questions about who we are and the world that we inhabit. And, yet, mysteries persist.

Why are we compelled to sleep every night? Why are we still not able to “see” dark matter? And where the heck are all the aliens?

People have debated questions like these for decades — sometimes centuries. Fortunately, our unfaltering will to uncover the world’s mysteries has brought us closer to some answers than ever before. Here are six mysteries that still keep scientists up at night, and how close they are to solving them.

Why Do We Need Sleep?

Why do we need sleep? This may seem like a straightforward question, but the answer is far more complex than you might think. There have been countless attempts to find a definitive reason as to why humans need to sleep every night, but scientists are still unable to offer a single, definitive answer.

Findings in sleep science have shed some light on the intricacies of sleep stages and brain activity, but ultimately, they have merely offered pieces to an ever-growing, incomplete puzzle. It doesn’t help that we don’t have much to compare ourselves to — as sleeping patterns and brain activity in other animals often deviate significantly from those of humans, further mystifying our understanding of sleep
