If the big bang happened 13.8 billion years ago, and the universe is 93 billion light years in diameter, how did the universe expand faster than light?

Answer 1

13.8 being the radius of a circle. Times 2 for the diameter. Times 3.14 for the circumference. Equals 86.66. Pretty close for simple math. Seems legit.
