“Mystery Moment in Time” –The Observable Universe’s Missing Antimatter

 

Cosmic Microwave Background

 

The Standard Model of particle physics has reigned triumphant for nearly half a century, confirmed by observation upon observation. Nevertheless, it fails to explain why the observable universe contain virtually no antimatter. Particles of antimatter have the same mass but opposite electrical charge of their matter counterparts. But they’ve never been seen. Such gaps have inspired physicists to search from subatomic particles to galaxies for laws of nature beyond the Standard Model.

“Shape-Shifting Cosmos” — Physicists Seek the Question to Which the Universe is the Answer

Early Galaxy

 

In 2013, one of the leading particle physicists of his generation, Nima Arkani-Hamed at the Institute for Advanced Studies in Princeton and Jaroslav Trnka, founding member of the Center for Quantum Mechanics and Physics, found that the amplitudes of certain particle collisions are encoded in the volume of a gem-like geometric object, which they named the amplituhedron, that makes reference to neither space nor time, raising metaphysical questions about the meaning of physics and the nature of reality

“Ultralight” –‘Dark Matter Exists Beyond the Standard Model’

 

Dark Matter

 

“Inconveniently, dark matter is “dark” in the sense that it hardly interacts with anything, particularly with light. Apparently, in some scenarios it could have a slight effect on light waves passing through. But other scenarios predict no interactions at all between our world and dark matter, other than those mediated by gravity. This would make its particles very hard to find,” says Sergey Troitsky, chief researcher at the Institute for Nuclear Research of the Russian Academy of Sciences.

MIT’s Search for Spooky Axions –“The Missing Mass of Cosmos”

Galaxy M87

 

While they are thought to be everywhere, axions are predicted to be virtually ghost-like, having only tiny interactions with anything else in the universe. “As dark matter, they shouldn’t affect your everyday life,” says MIT physicist Lindley Winslow. “But they’re thought to affect things on a cosmological level, like the expansion of the universe and the formation of galaxies we see in the night sky.”

Neutron Stars Merging

 

Since the historic finding of gravitational waves from two black holes colliding over a billion light years away was made in 2015, physicists are advancing knowledge about the limits on the precision of the measurements that will help improve the next generation of LIGO tools and technology used by gravitational wave scientists.

“Beyond the Standard Model” –A Frighteningly Infinite ‘Physics’ of Possible Worlds

Sagittarius A* Black Hole

 

“There are no laws of physics,” observed Robbert Dijkgraaf, mathematical physicist and director of the Institute for Advanced Study, where Einstein spent his last 22 years. Instead, he observes, there is a terrifying complex “landscape” of possibilities, a nearly infinite, subtly connected network of complementary versions of reality each with its own set of fundamental particles, forces, laws and dimensions.”
