Scientists and engineers are studying ways to make artificial muscles out of carbon nanotubes. these muscles are lightweight and can handle very high temperatures. they could be used in robots, but not in humans. what is the most likely way these muscles could lead to additional scientific progress? they could biologists understand how human muscles work. they could allow engineers to build robots that could make cars faster. they could allow scientists to explore remote places, like other planets, in new ways. they could chemists understand how to make new biomaterials for artificial human muscles.
