Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales. Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe.
Feb 5, 2024 · The short answer is: We don't know. But we do know that it exists, it’s making the universe expand at an accelerating rate, and approximately 68.3 to 70% of the universe is dark energy. The history of the universe is outlined in this infographic. NASA. A Brief History. It All Started With Cepheids.
Apr 24, 2024 · dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter -energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).
Nov 24, 2022 · Dark energy is a hypothetical form of energy that is proposed by physicists to explain why the universe is not just expanding but is doing so at an accelerating rate. Think of dark energy...

Argonne National Laboratory. Science 101: Dark Matter and Dark Energy. What are dark matter and dark energy? There’s something amiss in the cosmos. Mysterious influences seem to be stretching the universe apart and clumping stuff together in unexpected ways, but we can’t see or touch them.
The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent). Unlocking...
Dark matter. Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.
