The Alpha Magnetic Spectrometer (AMS-02), a particle detector aboard the International Space Station, has identified particles of antimatter (antihelium) that are not easily produced in the known universe. This discovery challenges current theories about the production of antimatter and suggests that we might be observing completely new astrophysical phenomena. Antihelium is the antimatter form of […]

Researchers Show for the First Time Gravity Can Exist without Mass or Dark Matter
For nearly a century, dark matter has been one of the most enigmatic concepts in astrophysics. This hypothetical form of matter is inferred from gravitational effects that cannot be explained by general relativity alone, suggesting the existence of unseen mass in the universe. Proposed by Dutch astronomer Jan Oort in 1932 to explain the missing […]

Scientists Claim Our Universe does not Contain Dark Matter
In a new study, researchers from the University of Ottawa have questioned the current theoretical model of the universe’s composition, which suggests that it is made up of “normal matter”, “dark energy,” and “dark matter”. The study, led by Professor Rajendra Gupta from the Faculty of Science’s Department of Physics, demonstrates that the universe may […]

Astronomers Detect Cosmic Web of Dark Matter Stretching Like a Spider Web Thousands of Light-Years Away
Scientists have achieved an important observational milestone with the detection of dark matter extending millions of light years from the Coma galaxy cluster. Using the Subaru Telescope’s wide-field Hyper Suprime-Cam, astronomers were able to capture the first images of wispy dark matter filaments connecting galaxy clusters over immense scales. Dark matter is believed to make […]
