Mathematicians Settle the Erdős Coloring Conjecture

https://ift.tt/eA8V8J
Mathematicians have now confirmed that to paint the sides of a linear hypergraph, you by no means want extra colours than the variety of vertices within the graph.Illustration: Kelsey Houston-EdwardsFifty years in the past, three mathematicians got here up with a graph idea downside that they thought they may clear up on the spot.

The Milky Approach Will get a New Origin Story

https://ift.tt/eA8V8J
Over the previous two years, astronomers have rewritten the historical past of our galaxy. When the Khoisan hunter-gatherers of sub-Saharan Africa gazed upon the meandering path of stars and dirt that cut up the night time sky, they noticed the embers of a campfire. Polynesian sailors perceived a cloud-eating shark. The traditional Greeks noticed a …

The Seek for Darkish Matter Is Dramatically Increasing

https://ift.tt/eA8V8J
Physicists are checking whether or not darkish matter tickles several types of detectors, nudges starlight, warms planetary cores, and even lodges in rocks. Ever since astronomers reached a consensus within the Eighties that many of the mass within the universe is invisible—that “darkish matter” should glue galaxies collectively and gravitationally sculpt the cosmos as an …

Is Darkish Matter Simply Black Holes Made Through the Massive Bang?

https://ift.tt/eA8V8J

Stephen Hawking once proposed that unseen “primordial” black holes might be the hidden dark matter. A series of new studies shows how it can work. Black holes are like sharks. Elegant, simple, scarier in the popular imagination than they deserve, and possibly lurking in deep, dark places all around us. Original story reprinted with permission …

Mathematical ‘Hocus-Pocus’ Saved Particle Physics

https://ift.tt/eA8V8J

Renormalization, a technique that helps bridge the big and the small, has become perhaps the single most important advance in theoretical physics in 50 years. In the 1940s, trailblazing physicists stumbled upon the next layer of reality. Particles were out, and fields—expansive, undulating entities that fill space like an ocean—were in. One ripple in a …

Mathematicians Report New Discovery In regards to the Dodecahedron

https://ift.tt/eA8V8J

Starting at a corner, could you walk around the surface of this Platonic solid without crossing other corners? To get the answer, you need an 81-holed doughnut. Mathematicians have spent more than 2,000 years dissecting the structure of the five Platonic solids—the tetrahedron, cube, octahedron, icosahedron, and dodecahedron—but there’s still a lot we don’t know …
