Scientists have found the first evidence that black holes are the source of dark energy
(ORDO NEWS) — Observations of supermassive black holes at the centers of galaxies point to a likely source of dark energy – the “missing” 70% of the universe. Measurements of ancient and dormant galaxies show that black holes are growing more than expected, in line with the phenomenon predicted by Einstein’s theory of gravity. The result potentially means that nothing new needs to be added to our picture of the…

Black holes are the source of dark energy, scientists say
(ORDO NEWS) — A surprising discovery from comparing the sizes of modern and ancient black holes could explain one of the biggest mysteries in physics. Observations have shown that black holes are much larger than they were nine billion years ago, even compared to the size of their galaxies. In an attempt to explain the magnitude of this anomaly, astrophysicists have found an explanation for dark energy, the mysterious force…

Radical theory suggests black holes are the source of mysterious dark energy
(ORDO NEWS) — Black holes could explain the mysterious form of energy that astronomers believe makes up much of the universe. The existence of “dark energy” has been made based on observations of stars and galaxies, but it has not been possible to explain what it is and where it comes from. The substance or matter that makes up the familiar world around us is only 5 percent of everything…

Astronomers have estimated the proportion of the mass of dark energy in the universe at 66.2%
(ORDO NEWS) — Dark energy makes up 66.2% of the total mass of the universe. In the 1990s, astronomers discovered that the expansion of the universe was gradually accelerating. This disproved the then ideas, according to which gravity should, on the contrary, gradually slow it down. To explain this phenomenon, astrophysicists introduced the concept of dark energy, a hypothetical substance that has negative gravity – gravitational repulsion. Often, dark energy…

In search of dark energy, the telescope stopped at the Lobster Nebula
(ORDO NEWS) — If you thought dark matter was hard to study, then dark energy is even harder to study. Dark energy is perhaps the most subtle phenomenon in the universe. It governs the evolution of the cosmos, but its effects are only visible on an intergalactic scale. Thus, to study dark energy in detail, you need many observations of large areas of the sky. That’s why the US Department…

Huge voids in space can generate dark energy
(ORDO NEWS) — People know surprisingly little about one of the biggest features of the cosmos, the giant ancient “voids” ( voids ). If the universe were a brain cell , then the cosmic voids would be something like the space between neurons – and they are absolutely huge, sometimes hundreds of millions of light-years long. Dark Energy Generator From now on , a new hypothesis admits the possibility that…

Information energy accounts for dark energy, resolves Hubble tension, avoids the ‘big chill,’ and is falsifiable
(ORDO NEWS) — Stellar heated gas and dust has an entropy, or information content, with an equivalent energy of 1070 joules, directly comparable to the mc2 equivalent energy of the universe baryon mass. In a study published in Entropy, Professor Paul Gough at the University of Sussex shows that this information energy can account for the dark energy causing the accelerating universe expansion. Earlier, the information energy density grew rapidly…

Does dark energy really exist or is it just an illusion ?
(ORDO NEWS) — Scientists have introduced dark energy to explain cosmological phenomena such as the accelerated expansion of the universe. But does science need it? Simulations of neutron star mergers have helped scientists test alternative theories of gravity and question whether dark energy is really needed to describe cosmological processes. For about 100 years now, general relativity has been very successful in describing gravity at various scales, passing all experimental…
