Gravity-Defying Breakthrough: Floating Sensor Unmasks Dark Energy’s Secrets




Scientists have made a groundbreaking leap in detecting dark energy by developing a magnetically levitated precision force system.

Their experiments vastly surpassed previous methods, reaching a new level of precision that opens up unexplored realms of dark energy research. The work was so impactful it earned a featured highlight in Nature Astronomy.

Breakthrough in Dark Energy Detection

Recently, a research team from the Department of Physics at Nanjing University, working alongside collaborators from the School of Astronomy and Space Science at Nanjing University, the University of Science and Technology of China, and Zhejiang University, achieved a major breakthrough in dark energy detection.

The team developed a magnetically levitated precision force measurement system, enabling high-precision experimental tests of the symmetron dark energy theory.

Unprecedented Leap in Experimental Precision

Their new system pushed the boundaries of experimental precision, improving the international state-of-the-art by six orders of magnitude. This advance allowed the researchers to explore a wide range of parameters that had been inaccessible to previous experimental setups.

The findings, published in Nature Astronomy under the title “Experimental constraints on symmetron field with magnetically levitated force sensor,” were highlighted as a featured article in the journal’s Research Briefings.

Dark energy is the mysterious force that makes up about 68% of the universe and is believed to be responsible for its accelerating expansion. Unlike ordinary matter and dark matter, dark energy doesn’t clump into galaxies or structures it acts more like a uniform energy field spread throughout space.

The concept emerged in the late 1990s when astronomers studying distant supernovae discovered that the universe’s expansion wasn’t slowing down (as expected due to gravity), but actually speeding up. This surprising discovery led to the idea that some unknown energy must be working against gravity on cosmic scales.

Scientists don’t yet know what dark energy actually is. It could be:
  • A cosmological constant (a built-in energy of empty space itself, as Albert Einstein once proposed),
  • A dynamic field (similar to “quintessence”),
  • Or something entirely different, possibly pointing to new laws of physics.

Despite its huge role in shaping the cosmos, dark energy remains one of the greatest unsolved mysteries in modern science, inspiring experiments and theories around the world to try to understand its true nature.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Scientists Discover New “Hall Effect” That Could Revolutionize Electronics

Scientists discovered a new Hall effect driven by spin currents in noncollinear antiferromagnets, offering a path to more efficient and resilient spintronic devices . A research team led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has identified a previously unknown type of Hall effect that could lead to more energy-efficient electronic devices . Their study, published in Physical Review Letters, was conducted in collaboration with graduate student Bastián Pradenas and Professor Oleg Tchernyshyov of Johns Hopkins University. The researchers uncovered evidence of a new property, dubbed the “Hall mass,” in a class of complex magnetic materials known as noncollinear antiferromagnets . The traditional Hall effect, discovered by Edwin Hall at Johns Hopkins in 1879, describes how an electric current is deflected sideways when subjected to an external magnetic field, generating a measurable voltage. This effect plays a crucial role in technologi...
