At the Tearing Seam, Time Turns Visible Two galaxies collide, and at the boundary where graphite-black dust lanes from the first disk meet ultraviolet-whitened star clouds from the second, Kelvin-Helmholtz billows are rolling while a starburst chain ignites bead by bead. The viewer feels a slow, ribcage-deep pulling pressure because warped crescents, time-graded tidal ribbons, and prismatic lensing arcs compress toward the center until the frame seems to bow inward.
