Despite being established 100 years ago, quantum mechanics continues to challenge our understanding of reality, shaking the foundations of classical physics and introducing concepts so strange they still baffle scientists and enthusiasts alike.

Now in celebration of this anniversary, Nature asked over 1,000 physicists for their thoughts on some of the field's most hotly debated questions.Perhaps the most striking takeaway was just how divisive these big questions remain - with experts disagreeing on nearly every major issue.

Adding to the complexity, many of the responses were characterized by uncertainty, reflecting the ongoing mysteries at the heart of quantum theory.

That said, most (86%) agreed that an intuitive, physical interpretation of math in quantum mechanics is valuable, while 72% agreed that quantum theory will eventually be replaced by a more complete theory.

Ultimately, this lack of consensus not only underscores the enigmatic nature of quantum mechanics itself but also highlights just how much there still is to discover in our quest to understand the universe.
