Constellations

This is a love story between two people who meet at a party and begin a romance. Or they meet at a bar. And there is no romance. Or there are sparks, but one is already in a relationship. Or they don’t really like each other. Playwright Nick Payne presents a poignant, powerful and playful play using theoretical physics, where there are different outcomes occurring at the same moment, maybe in different universes. Th 2pm & 7pm, F 8pm, Sa 2pm & 9pm, Su 2pm, Tu, W 6:30pm. Through 7/30. $26-$38. B Street Theatre, 2711 B Street; (916) 443-5300; www.bstreettheatre.org. P.R.
