A former NASA engineer claims to have developed a propulsion system powered by a 'New Force' that can generate thrust without expelling propellant, potentially overcoming Earth's gravity. However, such claims are highly controversial and require independent verification, as they challenge established physical laws.

Physicists at ETH Zurich are using precision atomic spectroscopy of calcium isotopes to search for a potential fifth force of nature, which could help explain mysteries like dark matter and extend beyond the Standard Model. Their experiments aim to detect subtle energy shifts that might indicate the presence of an unknown force carried by a new particle, although current results are inconclusive and further research is ongoing.

Physicists used antimatter, supercomputers, and giant magnets to resolve a 20-year-old mystery about the muon's magnetism, which could have indicated new physics related to dark matter. Recent experiments and simulations have clarified the discrepancy, but the question of potential new particles like the dark photon remains open, offering clues about dark matter.

New data from the James Webb Space Telescope confirms previous Hubble Space Telescope measurements of the Universe's expansion rate, suggesting discrepancies with theoretical models may indicate new physics. The study, published in The Astrophysical Journal, supports the accuracy of Hubble's data, ruling out measurement errors and highlighting a tension between observed expansion rates and predictions from the standard LambdaCDM model. Theorists are now exploring explanations such as early dark energy or exotic particles to resolve this "Hubble tension."

Physicists are investigating discrepancies in quark mixing predictions within the Standard Model, which currently do not sum to 100%, suggesting potential new physics. Researchers, including Jordy de Vries, have developed a new framework to more accurately calculate quark mixing, particularly between up and down quarks, using precise measurements from nuclear beta decays. This work aims to refine theoretical models and reduce uncertainties, potentially revealing new physics beyond the Standard Model.

Primordial black holes (PBHs), potentially formed after the Big Bang, may be exploding due to Hawking radiation, offering a chance to discover new physics. These explosions, detectable by upcoming telescopes, could reveal unknown particles and provide insights into dark matter. Theoretical physicists have developed methods to study PBHs' mass and spin during evaporation, which could revolutionize particle physics by confirming the existence of exotic particles like axions. Detecting an exploding PBH could significantly advance our understanding of the universe's fundamental laws.

An enormous intergalactic ring-shaped superstructure of galaxies and galaxy clusters, dubbed the "Big Ring," has been discovered, spanning 1.3 billion light-years in diameter and challenging current cosmological theory. This structure, along with the even larger "Giant Arc in the Sky," raises questions about the formation of such immense superstructures and their implications for our understanding of the universe. The discovery may hint at exotic forms of known physics or even new physics, such as Conformal Cyclic Cosmology or cosmic strings, as potential explanations for these enigmatic structures.

Astronomers have discovered the highest-energy outburst of light from a pulsar ever seen, indicating potential new physics around these dense, rapidly spinning dead stars. The gamma-ray output of the Vela pulsar was found to be around 200 times more powerful than average pulsars, with gamma-ray photons reaching 20 tera electron volts (TeV). This suggests that something unexpected is happening around the Vela pulsar and its polar jets, which have been observed to stretch as far as 0.7 light-years. The team proposed several possibilities for the powerful gamma-ray emission mechanism, including accelerated particles outside the standard light-cone zones, well-structured magnetic fields, or the bulk movement of winds from neutron stars. Further investigations will be conducted to understand the acceleration and emission processes in pulsars and their implications for other highly magnetized astrophysical objects.

A theoretical study conducted by researchers at the University of California–Santa Barbara, University of Warsaw, and University of Cambridge suggests that extremal Kerr black holes, a type of uncharged stationary black hole, could serve as "amplifiers" of new and unknown physics. The study shows that the higher-derivative terms in a gravitational effective field theory (EFT) can lead to singularities on the horizons of these black holes, with infinite tidal forces. The researchers found that the spacetime geometry near the horizon of extremal black holes is sensitive to new physics at higher energies, potentially breaking down the low-energy description of physics. This research opens up possibilities for exploring new physical phenomena and understanding the behavior of black holes.

Scientists are using atomic clocks to investigate the nature of dark matter and search for new physics beyond the Standard Model. Atomic clocks measure time using atoms with two energy states, and any variation in their resonance frequencies could indicate the presence of ultra-light particles associated with dark matter. By comparing two clocks, one sensitive to changes in fundamental constants and the other less sensitive, researchers can set constraints on these particles. This technique could also potentially be used to study dark energy. The results of this research are set to be published in the New Journal of Physics.

Scientists at the Institute of Nuclear Physics of the Polish Academy of Sciences propose that the Higgs boson may interact with ‘new physics’ via decay into exotic particles, according to ‘Hidden Valley’ models. These models suggest that future particle accelerators could observe this exotic decay, potentially paving the way for understanding new physics beyond our current Standard Model. Theoretical considerations suggest then the exotic decay of the famous Higgs boson, something that has not been observed at the LHC accelerator despite many years of searching.
