It is impossible to deny the amazing predictive power Albert Einstein‘s theory of gravity in 1915, general relativity – but the theory still has inconsistencies when it comes to calculating its effect over large distances. And new research suggests these discrepancies may be the result of a “cosmic glitch” in gravity. In the 109 years… Read More »
In 2009, theoretical physicist Erik Verlinde proposed a radical reformulation of gravity. In his theory, gravity not fundamental force Rather, it is a manifestation of deeper hidden processes. But in the 15 years since, there hasn’t been much empirical support for this idea. So where do we go next? Emergence is common throughout physics. For… Read More »
A newly developed solution to the equations at its center Albert Einstein‘s most revolutionary theory suggests that hypothetical stars called “nestars” could be made from gravitational stars stacked on top of each other, or “gravastars” like Russian tea dolls, also known as matryoshka dolls. One of the most fascinating things about general relativity, Einstein’s 1915… Read More »
Ancient cosmic light, which evenly filled the universe about 400,000 years after the Big Bang, may serve as a treasure map guiding scientists to the secrets of dark matter. The Cosmic Microwave Background (CMB) refers to the first light that circulated freely in the universe. Its journey began after space had expanded and cooled enough… Read More »
