What defines the boundary of the universe?

The boundary of the observable universe is defined by the age of the universe: You cannot observe parts of the universe that are too far away for light to have reached you given the finite age of the universe.

What is outside outer space?

Does outer space have boundaries?

International law does not define the edge of space, or the limit of national airspace. The FAI defines the Kármán line as space beginning 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above Earth’s mean sea level.

Karman Line
The invisible boundary that separates Earth from space, called the Karman Line, stands around 62 miles (100 kilometers) above Earth’s surface. As innocuous as it sounds, this boundary isn’t like crossing the state line; it’s violent, fiery and downright harrowing for astronauts and spacecrafts alike.
