3 new studies point to a conflict at the heart of cosmology

A collection of three scientific papers describing the historical past of the growth of the universe inform a complicated story, with predictions and measurements slightly disparate. (The papers could be accessed right here: OneAnd twoAnd three.) Whereas this disagreement isn’t a deadly refutation of contemporary cosmology, it could be a touch that our theories have … Read more

Research Shows Faster-than-Light Warp Is Possible (Probably)

It is going to take a faster-than-light “observer”. basic relativity to new quantum locations. In new analysis, a lead scientist explains why One house f One Not sufficient time for this situation. Symmetry is Physics An idea that dates again to the time of Galileo. The key to faster-than-light physics could also be doubling the … Read more

A “clump-less” universe may indicate the presence of mysterious forces astronomy

One of the crucial correct surveys of the universe’s construction has advised that it’s “much less lumpy” than anticipated, in findings that might point out mysterious forces at work. Notes written by Darkish Power Survey and the South Pole Telescope Charting the distribution of matter with the intention of understanding the competing forces which have … Read more

New analog quantum computers to solve previously unsolvable problems

Micrograph picture of the brand new quantum simulator, which options two converging nano-sized metallic semiconductor parts built-in into an digital circuit. Credit score: College Faculty Dublin Physicists have created a brand new sort of analog quantum pc that may deal with robust physics issues that even essentially the most highly effective digital supercomputers cannot. New … Read more

Physicists discover a new way to solve the strange mystery of dark energy

Physicists have proposed a brand new rationalization for darkish vitality. It may well shed insights into the interdependence between quantum area idea and common relativity idea, as two views of the universe and its components. What’s behind darkish vitality – and what hyperlinks it to the cosmological fixed launched by Albert Einstein? Two physicists from … Read more

The universe is a little hotter than it should be. The “dark photons” could be to blame.

Observations point out that the intergalactic fuel in our universe is barely hotter than it must be. Just lately, a crew of astrophysicists used subtle laptop simulations to suggest a radical resolution: an unique type of darkish matter often called “darkish matter”. photons“It could possibly be heating up the place. These unusual particles can be … Read more

Why more physicists are beginning to think that space and time are “illusions”

Final December, the Nobel Prize in Physics was awarded for the experimental affirmation of a quantum phenomenon recognized for greater than 80 years: entanglement. As conceived by Albert Einstein and his collaborators in 1935, quantum objects might be mysteriously associated even when they’re separated by nice distances. However as weird because the phenomenon sounds, why … Read more
