Einstein's Theory of General Relativity Validated on Cosmic Scale

Einstein's theories were tested with the most accurate large-scale gravity map of the universe. The researchers compiled a map of 6 million galaxies to test how gravity works on a large scale in the universe. This is the most accurate test. DESI (Dark energy Spectroscopic Instrument: Dark energy Spectroscopic Instrument) tracks how gravitational forces have shaped the universe over the last 11 billion years. They found that gravity behaves as Ei…

The Dark Energy Pushing Our Universe Apart May Not Be What It Seems, Scientists Say

Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought. Astronomers know that the universe is being pushed apart at an accelerating rate and they have puzzled for decades over what could possibly be speeding everything up. They theorize that a powerful, constant force is at play, one that fits nicely with the main mathematical model that describes how the universe behave…

Dark energy appears to be changing or weakening over time

Most precise large-scale gravity map of 6 million galaxies in the universe tests Einstein’s theories

Researchers have compiled a map of 6 million galaxies in the most precise test of how gravity works on large scales in the universe.

The survey, detailed in several pre-print papers on the arXiv server, uses data from the Dark Energy Spectroscopic Instrument (DESI). It tracks how gravitational forces have sh…

Findings by dark energy researchers back Einstein's conception of gravity

WASHINGTON : Scientists working in an international collaboration have tracked how the structure of the cosmos has grown over the past 11 billion years, providing the most precise test to date of how gravity behaves at very large scales. And what they found is that it acts as physicist Albert Einstein predicted

The dark energy pushing our universe apart may not be what it seems, scientists say

Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought. Astronomers know the universe is expanding at an accelerating
