1. • • Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together. This is because dark matter does interact with gravity, but it doesn’t reflect, absorb, or emit light. Meanwhile, dark energy is a repulsive force — a sort of anti-gravity — that drives the universe’s ever-accelerating expansion.

   Are dark matter and dark energy clumping the universe together?

   • In this Science 101 video, postdoctoral researchers Gillian Beltz-Mohrmann and Florian Kéruzoré explore two of the biggest mysteries in science: dark matter and dark energy. These strange influences seem to be stretching the universe apart and clumping stuff together in unexpected ways.

   Is dark energy the same as dark matter?

   • Despite the name, dark energy isn’t like dark matter, except that they’re both invisible. Dark matter pulls galaxies together, while dark energy pushes them apart. Astronomers measure the expansion of the universe using the explosions of white dwarfs, called type Ia supernovas, which led to the discovery of dark energy in 1998.

   How does dark matter affect the expansion of the universe?

   • In short, dark matter slows down the expansion of the universe, while dark energy speeds it up. Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together. This is because dark matter does interact with gravity, but it doesn’t reflect, absorb, or emit light.

   What influences dark energy and dark matter?

   • Scientists call these influences dark energy and dark matter. Humans have studied the sky for many thousands of years, and in the last century, scientists have really started to understand how the universe moves and changes under the influence of a force called gravity.

   Unlike dark matter, which clumps around galaxies, dark energy appears to be uniformly distributed across the universe. We also think that dark energy only came to dominate the makeup of the universe relatively late in time, about five billion years ago.
