We understand new things by putting them against what we already know—the differences and similarities that emerge help us grasp details in ways that abstract definitions often can't.
So for this list, we've compiled a set of funny, bizarre, and even unsettling comparisons. From everyday objects to cool inventions and rare natural phenomena, each side-by-side photo offers a fresh way to look at the world around us.
There are so many curiosities out there, we just have to open our eyes!
