Does the universe have an end?

The universe has existed for 13.6 billion years, and since the Big Bang the universe has been expanding rapidly, forming galaxies and stars in the universe, and constructing our present universe, and now that the universe is still expanding, scientists have suggested that the universe may not have an edge.

Because the universe as we know it now has always existed in an expanding state, there is no concept of the definition of the edge of the universe, and our exploration of the universe is still unable to understand.
