Where does outer space end?

Answer

Outer space could be said to have either multiple boundaries or none at all. The furthest objects that can be seen from Earth are approximately 13.8 billion light-years away.This marks the edge of the observable universe.

Over the 13.8 billion years that the light from distant objects has been traveling toward Earth, the universe has continued expanding. Those distant objects have reached a maximum distance of 46 billion light years.

By measuring the curvature of space, it is possible to get a sense of how much further space continues beyond that horizon. The measured curvature of space-time is nearly flat, suggesting a universe that extends outward for no less than 14 trillion light-years and possibly an infinite distance.
