. Together they make up 96 percent of the universeand we cant. More recently June 2021 The National Science Foundations Dark Energy Survey. For another thing dark. Dark matter is a form of invisible matter or mass whereas dark energy is a form of energy.

They are not created or destroyed in relevant amounts. Dark energy is an unquantified and poorly understood mechanism by which the universes expansion is. Dark energy is estimated to account for between around 68 to 72 of the universes total energy and matter its matterenergy budget meaning it heavily. As the universe expands the density of matter decreases.

Dark matter pulls galaxies together while dark energy pushes them apart. Dark matter is twenty one percent of the mass and dark energy is seventy four percent of the mass of the universe. Dark matter produces an attractive force gravity while dark energy produces a repulsive force antigravity. Scientists believe that dark matter consists of material not detectable by our current instruments while.

Dark matter is an unobserved form of mass that exerts a gravitational force on the observable universe. For one thing dark matter pulls galaxies and other objects together by gravitational attraction while dark energy is today pushing our accelerating universe apart.

Dark energy 101 But while we can say that dark matter is a thing dark energy is much more elusive and as its name suggests more dynamic. According to the data nearly 95 of the universe is a combination of dark matter and dark energy with 68 dark energy and 27 dark matter.
