The universe is a stage filled with extreme phenomena, where temperatures and energies reach unimaginable levels. In this context, there are objects such as supernova remnants, pulsars, and active galactic nuclei that generate charged particles and gamma rays with energies far exceeding those involved in nuclear processes like fusion within stars. These particles, as direct […]

Measurement that the universe expands at 67.4 kilometers per second per megaparsec confirms the validity of the cosmological model
Scientists have been debating how fast our universe is expanding, a rate that is called the “Hubble constant”. For the past 20 years, two main methods of measuring this rate have given different results, leading some to wonder if our understanding of the universe was incomplete. However, new data from the James Webb Space Telescope […]

Antimatter Detected on the International Space Station Reveals Unknown Physics
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 Propose Our Universe Expands by Merging with Other Smaller Parallel Universes
A new study published by researchers from the University of Copenhagen and the Tokyo Institute of Technology proposes an alternative theory to the standard cosmological model to explain the acceleration of the universe without the need for dark energy. Scientists agree that the Universe is expanding faster and faster, but they don’t all point to […]

Cosmas Indicopleustes, a Greek traveler and geographer, is the sole known medieval author who believed that the Earth was flat
Syrian Greek merchant Cosmas Indicopleustes, born in the 6th century, penned a controversial work ‘Christian Topography’. He rejected the Greek concept of a spherical earth and provided firsthand descriptions from his travels, including maritime trade and Arabian flora and fauna, influencing Western depictions of the region.
