Dark matter energy storage

What is dark matter & dark energy?

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.

Is the universe dominated by dark matter and dark energy?

Observations continue to indicate that the Universe is dominated by invisible components — dark matter and dark energy. Shedding light on this cosmic darkness is a priority for astronomers and physicists. What is the composition of the Universe? Deep view — a slice of the Hubble Space Telescope's view of the visible Universe.

Why is dark matter important?

The rest is composed of dark matter and dark energy, which are invisible but dominate the structure and evolution of the universe. 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.

How did dark matter affect the universe?

In that earlier era, dark matter and its associated gravity held the universe’s expansion rate in check. Such state of affairs changed dramatically over the next several billion years as the influence of dark energy overwhelmed that of dark matter.

How much dark matter is in the universe?

The data from that mission are in “exquisite” agreement with the model, says senior Planck researcher George Efstathiou, a cosmologist at the University of Cambridge, UK. The current Universe, Planck found, is about 70% dark energy, 25% dark matter and 5% ordinary matter — the stuff of stars, planets and people.

What is cold dark matter?

A consensus emerged around a theory called Λ cold dark matter (ΛCDM), in which cosmic history is largely the result of a struggle between the pull of dark matter and the push of dark energy. A section of a map of the Universe based on observations made by DESI shows patterns in the arrangements of galaxies.
