Do you think it is possible that a red supergiant could harbor an advanced civilization? Explain your reasoning
What will be an ideal response?
A red supergiant is a late-stage high-mass star in the advanced state of nuclear burning, that is, burning elements heavier than helium in its core. Its envelope is gigantic. Its age at this point is rather young since massive stars live short lives. With our assumptions above, an advanced civilization probably does not have enough time to develop.

Which statement below regarding the first law of thermodynamics is most correct?
a. A system can do work externally only if its internal energy decreases. b. The internal energy of a system that interacts with its environment must change. c. No matter what other interactions take place, the internal energy must change if a system undergoes a heat transfer. d.
