Shining a light on synthetic dimensions

Posted by in categories: physics, space

Humans experience the world in three dimensions, but a collaboration in Japan has developed a way to create synthetic dimensions to better understand the fundamental laws of the universe and possibly apply them to advanced technologies.

They published their results on January 28, 2022 in Science Advances.

“The concept of dimensionality has become a central fixture in diverse fields of contemporary physics and technology in past years,” said paper author Toshihiko Baba, professor in the Department of Electrical and Computer Engineering, Yokohama National University. “While inquiries into lower-dimensional materials and structures have been fruitful, rapid advances in topology have uncovered a further abundance of potentially useful phenomena depending on the dimensionality of the system, even going beyond the three available in the world around us.”

Scientists make a new type of optical device using alumina

Posted by in categories: cosmology, physics

Scientists from the Kavli Institute for the Physics and Mathematics of the Universe and the University of Minnesota, Tomotake Matsumura and Shaul Hanany, and their collaborators have made a new type of optical element that will improve the performance of telescopes studying radiation from the Big Bang.

The (CMB) is a relic radiation remnant from the big bang. It reaches our telescopes after traveling 14 billion years since the birth of the Universe. Studying the properties of this radiation, scientists infer the physics of the , how clusters of galaxies form, and the matter and energy content in the Universe. Four Nobel prizes have been awarded for past studies of the CMB.

To study the CMB, telescopes must be tuned to wavelengths in which it is most intense, about 1–3 mm, and they must separate out shorter wavelength radiation that the atmosphere and Milky Way emit. Among the most effective optical elements that absorbs the short wavelength radiation but lets the CMB pass through is alumina, a material made of aluminum and oxygen and that is second in hardness only to diamond. One challenge with using alumina is that it also reflects almost 50% of the radiation impinging on it. Matsumura and Hanany have now come up with a new way to fabricate anti-reflective structures that reduce reflections fifty-fold.

A Mystery Object in Space Flashed Brilliantly for 3 Months—Then Disappeared

Posted by in categories: physics, space travel

The amazing thing about radio transients is that if you have enough frequency coverage, you can work out how far away they are. This is because lower radio frequencies arrive slightly later than higher ones depending on how much space they’ve traveled through.

Our new discovery lies about 4,000 light years away—very distant, but still in our galactic backyard.

We also found the radio pulses were almost completely polarized. In astrophysics this usually means their source is a strong magnetic field. The pulses were also changing shape in just half a second, so the source has to be less than half a light second across, much smaller than our sun.

NASA’s First Test to Lower the Sound of Sonic Booms Was Successful

Posted by in categories: nuclear energy, physics, transportation

The Concorde’s successor might be quieter.

NASA has completed the first test of the works on lowering the volume of supersonic flights in an effort to lift the ban on commercial supersonic flights, NASA’s Glenn Research Center announced.

The sonic booms happen when the merge of shock waves, created by breaking the sound barrier at the speed of 767 mph (1,235 kph). The huge amount of sound energy, approximately 110 decibels, generated by sonic booms sounds like thunderclaps or explosions and can be heard from 30 miles (48 km) away, which is why supersonic commercial flights are banned by the Federal Aviation Administration (FAA). physicists confirm that they have achieved a stage in nuclear fusion called “burning plasma”.

How Lecturers Without Borders Shares The Joy Of Science

Posted by in categories: alien life, chemistry, mathematics, nanotechnology, neuroscience, physics, robotics/AI, science, sustainability

If you are a scientist, willing to share your science with curious teens, consider joining Lecturers Without Borders!


Established by three scientists, Luibov Tupikina, Athanasia Nikolau, and Clara Delphin Zemp, and high school teacher Mikhail Khotyakov, Lecturers Without Borders (LeWiBo) is an international volunteer grassroots organization that brings together enthusiastic science researchers and science-minded teens. LeWiBo founders noticed that scientists tend to travel a lot – for fieldwork, conferences, or lecturing – and realized scientists could be a great source of knowledge and inspiration to local schools. To this end, they asked scientists to volunteer for talks and workshops. The first lecture, delivered in Nepal in 2017 by two researchers, a mathematician and a climatologist, was a great success. In the next couple of years, LeWiBo volunteers presented at schools in Russia and Belarus; Indonesia and Uganda; India and Nepal. Then, the pandemic forced everything into the digital realm, bringing together scientists and schools across the globe. I met with two of LeWiBo’s co-founders, physicist Athanasia Nikolaou and math teacher Mikhail Khotyakov, as well as their coordinator, Anastasia Mityagina, to talk about their offerings and future plans.

Julia Brodsky: So, how many people volunteer for LeWiBo at this time?

WSU Master Class: Inflationary Cosmology with Alan Guth

Posted by in categories: cosmology, physics

Breakthrough Prize winner Alan Guth developed the theory of inflation to answer to our cosmic origins. It’s one of the most studied and debated theories in cosmology, with research propelling Guth’s work to the forefront of scientific conversation.

In this Master Class, Professor Guth addresses what experiments could potentially rule out the BICEP2 results. Since recording this in 2017, the Planck spacecraft collected the data that Professor Guth anticipated, which shows that the initial observations were likely an artifact of interstellar dust, not primordial gravitational waves.
