2025/10/24

MIT scientists have found the first direct evidence of material from the original “proto-Earth” — the planet that existed before the giant impact that formed our world 4.5 billion years ago.By detecting an unusual potassium-40 isotope imbalance in ancient rocks from Greenland and Hawaii, researchers revealed remnants of Earth’s earliest building blocks — material that even meteorites don’t fully capture.

2025/10/13

A new study from the University of Ottawa is shaking up our understanding of the universe. Professor Rajendra Gupta suggests that dark matter and dark energy might not exist at all — instead, the forces of nature themselves are slowly weakening as the universe expands.This idea could explain cosmic mysteries — like why galaxies spin so fast or why the universe is expanding so rapidly — without invoking any unknown particles. Published in Galaxies, the research even suggests the universe may be

2025/10/04

New research suggests that Uranus’ moon Ariel may have once harbored a massive subsurface ocean over 100 miles deep. By analyzing fractures and ridges on its surface, scientists linked these features to tidal stresses from Ariel’s past eccentric orbit.The findings raise the possibility that Ariel—and perhaps Miranda—are twin ocean worlds, offering an exciting target for future space missions.
