garrett morgan changed the world by inventing the stop light and saving people's lives bye doing so.
Thomas Edison faced difficulties inventing the light bulb due to the complexity of finding the right material for the filament, developing a reliable vacuum for the bulb, and creating a cost-effective design. He conducted numerous experiments and tested thousands of materials before finding a working solution.
