By tracking individual quarks as they blasted through the plasma, researchers saw them leave behind ripples, splashes, and swirling wakes much like a duck moving through water. The finding suggests this primordial “soup” is so dense that it can slow speeding quarks and respond collectively as a fluid.

Dark features on the enormous Sputnik Planitia glacier appear consistent with liquid nitrogen rising through cracks from deep beneath the ice. Computer models show that nitrogen could melt at the glacier’s base and travel upward like fluid through small conduits. The finding reveals that Pluto may be much more geologically active than its frozen appearance suggests.

No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area of stronger agreement stood out: 68% said the Big Bang does not necessarily represent the beginning of time. Researchers say the divisions show just how alive and unsettled the frontiers of physics remain.

In some systems, those flares mysteriously fade with every return. Researchers now think the key may be stars that were already spinning extremely fast before being captured. That rapid rotation could explain both the fading flares and how the stars ended up in such extraordinarily tight black hole orbits.

Physicists created a new model predicting how dark matter could subtly distort gravitational waves produced during black hole mergers. When they tested the method on real LIGO data, one signal stood out as potentially carrying a dark matter imprint.

The team linked reports of eerie red auroras with spikes of carbon-14 trapped in buried wood, revealing a powerful solar radiation event around 1200 CE. The findings suggest the Sun was far more active at the time, with unusually short solar cycles.

Built using data from over 47 million galaxies and quasars, this map could unlock new clues about dark energy—the mysterious force driving the universe’s expansion. Despite setbacks like wildfire disruptions, the international DESI collaboration powered through, gathering an unprecedented dataset that already hints dark energy may behave in unexpected ways.

New research suggests that faint, ancient gravitational waves might have transformed into particles that eventually became the invisible substance shaping galaxies today.

While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly.

Scientists analyzing seismic data found that human-generated vibrations, usually caused by traffic, construction, and daily activity, dropped sharply during totality. The effect was so pronounced that it created a clear “seismic hush” across urban areas directly in the eclipse’s path, before quickly rebounding afterward.

Now, researchers propose a bold twist: dark matter might not be a single particle at all, but a mix of two different types that must interact with each other to produce detectable signals.
