Why So Dense?
If you were on Jeopardy! and the question was: “the densest object in the universe,” would you guess correctly? Some might think it’s some type of metal, but that isn’t the case at all.
Black holes are the densest objects in the universe! That’s pretty hard to imagine, but it certainly is the truth. Scientists haven’t discovered anything out there that could dethrone the dense king. For better understanding, the density is similar to squeezing Earth inside a sphere with a nine-millimeter diameter.
