Is the universe infinite?
The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us.
What is the border of the universe called?
The observable Universe is bounded by a ‘cosmic horizon‘, much like the horizon at sea. Just as we know there’s more ocean over the horizon, we know there are more galaxies (possibly an infinite number) beyond the cosmic horizon. Their light simply hasn’t had time to reach us yet.
How far is the border of the universe?
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction.
