Indeed, what we think of as gravity is just a ... Dark energy is a concept developed to describe the intrinsic expansive energy associated with a vacuum. This is Einstein’s infamous “cosmological constant” which keeps the universe from collapsing upon itself under its own gravity. The amount of dark energy is directly dependent upon the volume taken up by vacuum in the universe. Jun 15, 2023 · Most astronomers assume dark matter consists of undiscovered particles created in the very early universe that weakly interact with planets, stars, our bodies, and ourselves. They call this WIMPS, for Weakly Interacting Massive Particles. It’s not farfetched. The universe’s most common particle is the neutrino. Nov 5, 2020 · A lot of these structures are what’s known as dark matter. Scientists believe dark matter is the glue holding galaxies together and the organizing force giving the universe its overall structure. It comprises around 80 percent of all mass. Catching a glimpse of it is exceedingly difficult, however. Dark matter doesn’t emit, reflect, or ...

The amount of dark energy is directly dependent upon the volume taken up by vacuum in the universe.

The dark stars would be composed mostly of normal matter, like modern stars, but a high concentration of neutralino dark matter present within them would generate heat via annihilation reactions between the dark-matter particles. This heat would prevent such stars from collapsing into the relatively compact and dense sizes of modern stars and ...What Is Dark Matter: All You Need To Know. Image Credit: Unsplash.
