The wrong fossil rewrites the history of the Indian subcontinent for the second time

What initially seemed like a Dickinsonia fossil (left) decomposed and started to peel off the rock in just a few brief years (proper), an indication that it was one thing more moderen.

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

One of the vital 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 Vitality Survey and the South Pole Telescope Charting the distribution of matter with the purpose of understanding the competing forces which have … 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 might shed insights into the interdependence between quantum area idea and normal relativity idea, as two views of the universe and its parts. What’s behind darkish vitality – and what hyperlinks it to the cosmological fixed launched by Albert Einstein? Two physicists from the … 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 needs to be. Not too long ago, a staff of astrophysicists used refined pc simulations to suggest a radical answer: an unique type of darkish matter generally known as “darkish matter”. photons“It may very well be heating up the place. … 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 identified for greater than 80 years: entanglement. As conceived by Albert Einstein and his collaborators in 1935, quantum objects will be mysteriously associated even when they’re separated by nice distances. However as weird because the phenomenon sounds, why … Read more
