2021: a year physicists asked, ‘What lies beyond the Standard Model?’
Posted by Genevieve Klien in categories: physics, space
If you ask a physicist like me to explain how the world works, my lazy answer might be: “It follows the Standard Model.”
The Standard Model explains the fundamental physics of how the universe works. It has endured over 50 trips around the sun despite experimental physicists constantly probing for cracks in the model’s foundations.
With few exceptions, it has stood up to this scrutiny, passing experimental test after experimental test with flying colors. But this wildly successful model has conceptual gaps that suggest there is a bit more to be learned about how the universe works.

Black Holes of All Shapes and Sizes in Largest Catalog of Gravitational Wave Events Ever Assembled
Posted by Genevieve Klien in categories: cosmology, physics
The largest catalog of gravitational wave events ever assembled has been released by an international collaboration that includes Penn State researchers. Gravitational waves are ripples in space time produced as aftershocks of huge astronomical events, such as the collision of two black holes. Using a global network of detectors, the research team identified 35 gravitational wave events, bringing the total number of observed events to 90 since detection efforts began in 2015.
The new gravitational wave events were observed between November 2019 and March 2020, using three international detectors: The two Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory supported by the National Science Foundation and operated by Caltech and MIT. It’s designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. It’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves. It consists of two widely separated interferometers within the United States—one in Hanford, Washington and the other in Livingston, Louisiana.

The Evolution of Robotics- The Story Behind and it’s Future
Posted by Genevieve Klien in categories: physics, robotics/AI
As robotics is growing, tech enthusiasts are looking beyond the story of the evolution of robotics and learning deeply about what is robotics. This article deals with the robotics evolution.
A magnetic field can be used to switch nanolasers on and off, shows new research from Aalto University. The physics underlying this discovery paves the way for the development of optical signals that cannot be disturbed by external disruptions, leading to unprecedented robustness in signal processing.

2021’s Biggest Breakthroughs in Physics
Posted by Chris J. Kent in categories: physics, space
It was a big year. Fermilab discovered possible evidence of new physics with the muon G-2 experiment. Physicists created a time crystal, a new phase of matter that appears to violate one of nature’s most cherished laws. And we got a glimpse of an enormous pair of bubbles towering over the Milky Way.

Tsunamis’ magnetic fields are detectable before sea level change
Posted by Quinn Sena in categories: chemistry, physics
A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and could improve warnings of these giant waves.
Tsunamis generate magnetic fields as they move conductive seawater through the Earth’s magnetic field. Researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, but they lacked simultaneous measurements of magnetics and sea level that are necessary to demonstrate the phenomenon.
The new study provides real-world evidence for using tsunamis’ magnetic fields to predict the height of tsunami waves using data from two real events—a 2009 tsunami in Samoa and a 2010 tsunami in Chile—that have both sets of necessary data. The new study was published in AGU’s Journal of Geophysical Research: Solid Earth, which focuses on the physics and chemistry of the solid Earth.
