11 Questions Scientists Still Can't Answer

Scientists have made great strides in understanding the universe and the natural world, but there are still many mysteries that remain unanswered. For example, why is the universe expanding? And what is dark matter? These are just two of the questions that continue to puzzle scientists. Another mystery is the link between quantum mechanics and gravity. Quantum mechanics governs the behavior of subatomic particles, while gravity is the force that keeps planets in orbit around stars. Despite years of research, scientists have been unable to find a way to reconcile these two theories. As a result, some of the most fundamental aspects of the universe remain shrouded in mystery. But that doesn't stop scientists from trying to find answers. After all, that's what science is all about: asking questions and seeking out answers.

There are several things that still remain undiscovered. Those nerds don't know everything; here are 11 simple questions those eggheads can't crack.
