Question

Why are the very first stars thought to have been much more massive than the sun? (a the clouds that made them were much more massive than todays star-forming clouds. (b the temperatures of the clouds that made them were higher because the clouds consisted entirely of hydrogen and helium. (c star-forming clouds were much denser early in time?

Answer 1

I think the correct answer would be that the temperature of the clouds that made the very first stars where thought to be higher since the clouds are made up of hydrogen and helium. Hope this answers the question. Have a nice day.

Answer 2

The main reason why the very first stars where thought to be much bigger than the sun because of the temperature of the clouds that these stars were made of were higher. The clouds that mostly form these stars consist of entirely hydrogen and helium. The answer for this would be option B.
