Manager’s Pro Answer: Yes, scientists should build many more radio telescopes. They work very well. Scientists can use them day or night. Cloudy skies do not affect them. Scientists can better understand outer space with these telescopes. If there are more radio telescopes, scientists can make more discoveries.
Manager’s Con Answer: No, scientists do not need to build many more radio telescopes. Having many radio telescopes will not make a difference. Radio telescopes are usually big. They are expensive. It would be better to build one big and powerful radio telescope instead of many smaller ones. One big radio telescope would make more discoveries.
