We're answering some cool and interesting questions you sent us in this episode. We answer questions about cats, numbers, and planets! Discover why cats have whiskers and tails, how ancient humans counted before numbers existed, and why numbers never end. We'll also explore why planets are round, whether Earth will last forever, and what might happen if you fell through a hole to the other side of the planet.
