How Many People Would Need to Take Part in This Project?

If you found one dyson sphere, you would probably find millions or billions or trillions of them in in just one section of the universe. There is some sort of weird transit, a pattern where the light dims randomly around these stars. They have no idea what could be massive enough to dim those two stars that much. So maybe these are evidence of dyson's spheres, eh? I mean, it's possible.
