A photovoltaic Dyson sphere is a theoretical megastructure that could provide vast amounts of energy for interstellar space travel and large-scale technological endeavors.

In other words, if scientists can show that Earth's core contains a lot of helium-3, it will strongly suggest that the planet formed quickly, settling a long-standing debate about the birth of the ...
