| A slice through the invisible universe of dark matter is shown here extending from the present, located at the centre, to the most distant regions observable by the Euclid satellite, 10 billion light years to the left and right. The mission of Euclid will be to indirectly measure this network-like structure through the effect of gravitational lensing. Since light will have taken 10 billion years to travel from the left and right sides of the image to "us" in the center, we see that the Universe in the past looked considerably smoother, and that the large empty regions, known as voids, are much more prominent at the present. | A slice through the invisible universe of dark matter is shown here extending from the present, located at the centre, to the most distant regions observable by the Euclid satellite, 10 billion light years to the left and right.
