ALT An array of sensors appear as a set of rectangles within a gold-colored metal frame.

ALT A person stands observing a complex setup of scientific equipment and wires in a laboratory. Text on the image reads: "$37.5M U.S. National Science Foundation award aims to define new quantum frontiers." The CU Boulder logo is shown at the bottom.

ALT Illustration of a black hole viewed head-on. A bright, warped ring of light from the surrounding accretion disk encircles a dark central region. Overlaid on the black interior is a red grid curving across a spherical shape, with circular patterns at opposite sides, representing the geometry of spacetime near the singularity.

ALT Illustration of two glowing, blurred objects approaching one another inside a black hole. The objects appear near the center of a red curved spacetime grid overlaid on the dark interior, suggesting two observers falling toward the singularity from different angular directions. A distorted ring of light surrounds the black hole.

ALT Illustration showing bright, glowing trajectories converging toward a black hole. Pale yellow arcs sweep inward across a red spacetime grid overlaid on the black interior, depicting paths through curved spacetime. A warped ring of light from the surrounding accretion disk frames the black hole against a star-filled background.
