Scientists Find Evidence That Black Holes Are The Cause Of Dark Energy – SlashGear

So far, experts have proposed varied theories behind dark energy. The first one says that dark energy is an integral property of space itself, adding it is weaved right into the fabric of space-time as we know it. The other version borrows from Einstein’s gravity theory and claims that empty space can carry its own energy, but only after factoring in a concept called the cosmological constant. There are also quantum explanations, and even one that says dark energy actually acts like a fluid filling space, but one that affects the expansion of the universe in mysterious ways.

One of the more extreme possibilities was that Einstein’s gravity theories missed the mark. However, the latest research disproves that plausibility. “Black holes in Einstein’s theory of gravity are the dark energy,” says former Imperial College London student Duncan Farrah, one of the authors of the two research papers published in The Astrophysical Journal and The Astrophysical Journal Letters. “Stellar remnant black holes are the astrophysical origin of dark energy,” concludes one of the research papers.

Ever since scientists discovered that the universe is expanding, experts have been baffled by the unknown process that fuels it. It was thought that since the gravitational force between cosmic bodies holds things together, it should ideally resist the expansion of the universe instead of causing an expansion. The latest research notes that black holes are fundamentally tied to the expansion of the universe, a phenomenon that is dubbed “cosmological coupling.”
