Observable universe is 93 billion light-years in diameter and around 46.5 billion light-years from earth to the edge of the Observable universe in any direction.
To put that in a little more context, it would take 25,000 years to travel to the edge of the observable universe at light speed.
Should you want to make it from one end of the Observable universe to the other at a more reasonable speed of 65mph, the New York Times reckons it would take you a steady 480,000,000,000,000,000 years to get there.
