  There are a series of mathematical problems which people are currently unable to solve known as the “Millennium Prize problems”. These would be pretty cool – https://en.wikipedia.org/wiki/Millennium_Prize_Problems

  Ooo this is a great question! I think the question I most want an answer to is completely outside of my field as a dementia researcher and is based on pure curiosity: does other life exist in the universe? I think its just such a fantastically inspiring concept to imagine a race of beings just as complicated as humans but potentially completely different. Though perhaps the fun to that question is the wondering rather than the solution itself.

  What the missing gear on the Anitikyethrera mechanism did, and who built it.
  
  The Antikythera Mechanism is a mechanical computer with gears and wheels found in a shipwreck in the Mediterranean, and it is much older than other gear driven devices we know about. I’d love to go back in time and see who built it, why and what all the bits do.
