A Filament of Dark Matter Is Bending Light 10 Billion Years Away

[00:00:00]A single strand of dark matter, invisible but immense, is bending the light of galaxies behind it across billions of years.

[00:00:07]This filament, part of the cosmic web, stretches through space like a ghostly highway. Using gravitational lensing, astronomers at the University of British Columbia mapped its shape by observing how it warps the glow of distant galaxies.

[00:00:22]Dark matter doesn't emit or absorb light, but its gravity acts like a lens, revealing its presence. This specific observation confirms that dark matter filaments funnel ordinary matter into galaxies, shaping the large-scale structure of the universe.

[00:00:37]Scientists are now studying how these filaments evolve over cosmic time.
