Is there anything you think humans will ever be able to figure out? I think there will be a lot of things that will give us a hard time figuring out, but maybe we could at some point. I think about these questions:
What is the purpose of dreaming? What is the size of the whole universe? Will we ever seriously become an interplanetary species without any consequences? Are parallel universes real? How can the world achieve peace and become borderless? I'm curious to know what's on your list?

A "licking machine" designed by Purdue engineering students averaged 341 licks to the center. A similar experiment at the University of Michigan landed on 411 as the magic number. Students at Bellarmine University in Louisville used human subjects and looked at additional factors such as gender and candy color to get to a final number; they found that an orange Tootsie Pop takes an average of 148 licks to consume, while a grape pop averages 198 licks.
