Expansions refer to the process of increasing in size, volume, or scope. This can occur in various contexts, such as in business, where a company may expand its operations to new markets or increase its product offerings. In science, expansions can describe the growth of the universe or the physical expansion of materials when heated. In economics, expansions often relate to periods of growth in the economy, characterized by rising employment and increased consumer spending. During these times, businesses may invest more in resources and infrastructure to meet higher demand. Understanding expansions helps individuals and organizations plan for future opportunities and challenges.
