If you could detect a bowling ball’s gravitational waves, you would know when someone threw the ball—even if you were standing outside the bowling alley.
A growing suite of computational instruments is helping scientists determine how fast local concentrations of dark matter move, which in turn could help them cut in on the dance of dark matter particles.
From supernova explosions to writhing tendrils of dark matter, visualizations give new life to models and theories.
