There are several synonyms used to describe this phenomenon, including tipping point, saturation point, threshold, breaking point, and boiling point. These terms describe the level at which a change becomes inevitable, and any small addition or subtraction could cause a significant shift in the system. Understanding the concept of critical mass is essential in decision-making, whether related to marketing campaigns, social movements or environmental policies. The synonym we choose to use can depend on context, audience or personal preference.
