Re: Geoff Marcy has received a grant to look for Dyson spheres

I like the idea, I really do.

But can we tell with current technology the difference between a Dyson Sphere or even a nonsensical Dyson Shell from a regular old dim or small star? Or would a Dyson Sphere's star appear as otherwise normal star that was clearly dimmed?
