A Ripple in Spacetime
12+ hour, 27+ min ago (129+ words) Slate On this day in 2015 gravitational waves were detected for the first time by the Advanced LIGO interferometers in Louisiana and Washington state. The waves, predicted by Einstein’s general relativity, are caused by the rippling of spacetime caused by movement…...
Is the expansion of the Universe slowing down: a new debate in cosmology
16+ hour, 33+ min ago (309+ words) Zamin.uz Astrophysicists from Yonsei University in South Korea have reignited one of the most intense scientific debates in modern cosmology with a new study published in the Monthly Notices of the Royal Astronomical Society The scientists argue that the…...
Classic Moon-formation simulations typically produced a ring of debris that assembled over months or years after a Mars-sized world struck early Earth. But simulations published in September 2026 that included temperature-dependent rock strength found that, under certain conditions, a coherent Moon-sized satellite could emerge in roughly five hours.
1+ day, 58+ min ago (1286+ words) A September 2026 impact study found that strength retained by hot, partly solid rock can redirect Theia’s rebound and capture a coherent satellite within hours. By Terra Daily Editorial Team · Editorial process Published September 13, 2026 For decades, the standard computer version of…...
French Scientists Create a New Form of Ice at Temperatures That Would Vaporize Steel
1+ day, 53+ min ago (441+ words) A team of French researchers has produced a previously unconfirmed type of ice that forms not in the cold, but under crushing pressure and heat exceeding 3,600 degrees Fahrenheit. The findings, published in Physical Review Letters, add detail about conditions deep…...
Could the Clues to Ancient Alien Civilizations Be Hiding in a Bucket of Moon Dust?
1+ day, 3+ hour ago (140+ words) Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has been focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That creates a huge “synchronicity” problem - what if there aren’t any alien…...
A website where you can experience what would happen if the speed of light was 5 km/h.
1+ day, 5+ hour ago (171+ words) It is believed that when traveling at near-light speed, the colors of the surroundings and the shapes of objects appear to change. A web application called 'Relativity Park' has been released that allows you to experience 'how the world looks…...
Early-Universe Plasma May Have Kept Dark Photons From Heating the Cosmos
1+ day, 5+ hour ago (282+ words) Dark photons are one proposed explanation for dark matter. A new calculation suggests that the early universe’s plasma may have stopped them from depositing heat as efficiently as earlier models predicted. The post Early-Universe Plasma May Have Kept Dark Photons…...
