The idiom "push the envelope" originated in aviation, where it referred to testing the limits of an aircraft's performance. Test pilots pushed against these limits in daring maneuvers. Over time, the phrase expanded beyond aviation, symbolizing pushing boundaries or taking risks in different areas like technology and art. It's now widely used as a metaphor for innovation and pushing the limits of what's known or accepted.
