If the observable universe's length is over 92,000,000,000 lightyears, and the universe itself is about 13,800,000,000 years, it means the universe is expanding greater than the speed of light. How is it possible? Nothing can travel faster than the speed of light!
Answers
A key feature of this expansion is how uniform it is. Imagine a bunch of folks standing around the edges of a stretchy piece of fabric, tugging at it. Let us assume they're choreographed well and are able to walk backward and pull at the same rate. You, standing in the middle, would correctly observe that your "universe" is expanding: any objects placed on that fabric would slowly move away from you.
