  1. Jun 27, 2019 · Dark matter is stuff in space that has gravity, but it is unlike anything scientists have ever seen before. Together, dark matter and dark energy make up 95% of the universe. That only leaves a small 5% for all the matter and energy we know and understand. This might be a surprise, but we don’t know what most of the universe is made of.

    Dark Matter. The identity of dark matter - the mysterious stuff that makes up about 22% of the Universe’s energy contents - continues to elude scientists decades after they first inferred its existence. The leading candidate that might explain the fundamental make-up of dark matter is a hypothetical particle called the weakly interacting ...

  3. Aug 19, 2010 · What is dark energy? More is unknown than is known — we know how much there is, and we know some of its properties; other than that, dark energy is a mystery — but an important one. Roughly 70% of the Universe is made of dark energy. Dark matter makes up about 25%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter adds up to less than 5 ...

    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.

  6. Jul 19, 2019 · Dark matter may be made of baryonic or non-baryonic matter. To hold the elements of the universe together, dark matter must make up approximately 80% percent of the universe. The missing matter ...

  7. Dec 15, 2021 · 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).. Originally known as the “missing mass,” dark matter’s existence was first inferred by ...
