Focusing on Cygnus X-1, one of the first known black holes, they measured jets blasting out with the energy of 10,000 Suns and moving at half the speed of light. By watching these jets get pushed and bent by the fierce stellar winds of a nearby supergiant star, researchers could calculate their true power for the first time.

These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature. The effect doesn’t change how much light atoms emit, which is why it’s gone unnoticed until now. If confirmed, this approach could lead to ultra-compact detectors using cold-atom systems.

Scientists suggest these black holes could carry a mysterious “dark charge,” causing rare but powerful bursts of energy that current detectors might occasionally catch. This could explain why only one experiment saw the event. The theory also opens the door to discovering entirely new particles and possibly uncovering the nature of dark matter.

But they’re far from nothing. Even in these vast empty regions, the fundamental quantum fields that fill all of space remain, carrying a small but real amount of energy known as vacuum energy, or dark energy. While this energy is overwhelmed by matter in galaxies and clusters, in the deep emptiness of cosmic voids it becomes dominant.

Researchers at TU Wien have now taken a new step toward that goal by rethinking one of relativity’s core ideas: the paths particles follow through curved spacetime, known as geodesics. By creating a quantum version of these paths—called the q-desic equation—the team showed that particles moving through a “quantum” spacetime may deviate slightly from the paths predicted by classical relativity.

Scientists have traced this “gravity hole” to slow, deep movements of rock inside Earth that unfolded over tens of millions of years. Using earthquake data to essentially create a CT scan of the planet’s interior, researchers reconstructed how the anomaly evolved and discovered that it strengthened between about 50 and 30 million years ago.

Its clarity allowed scientists to measure multiple “tones” from the collision, all matching Einstein’s predictions. That confirmation is exciting—but so is the possibility that future signals won’t behave so neatly. Any deviation could point to new physics beyond our current understanding of gravity.

But a new study suggests this mysterious ingredient may not be necessary after all. Using an extended version of Einstein’s gravity, researchers found that cosmic acceleration can arise naturally from a more general geometry of spacetime. The result hints at a radical new way to understand why the universe keeps speeding up.

Some theories of quantum gravity suggest light might behave slightly differently at extreme energies. By tracking ultra-powerful gamma rays from distant cosmic sources, researchers searched for tiny timing differences that could reveal new physics. They found none, but their results tighten the limits by a huge margin.

By transferring minute amounts of energy between light and gravity, the interaction would leave behind faint but detectable fingerprints. The setup resembles advanced gravitational-wave detectors like LIGO, but pushes them further into quantum territory. Success could hint at the long-sought quantum nature of gravity.

These dimensions could twist and evolve over time, forming stable structures that generate mass and symmetry breaking on their own. The approach may even explain cosmic expansion and predict a new particle. It hints at a universe built entirely from geometry.

By comparing how galaxies move through cosmic gravity wells to the depth of those wells, researchers found that dark matter appears to behave much like ordinary matter, obeying familiar physical laws. Still, the possibility of a hidden fifth force lingers, one that must be very weak to have evaded detection so far.

To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers presents a novel machine learning method that can analyze gravitational waves emitted by neutron star collisions almost instantaneously -- even before the merger is fully observed. A neural network processes the data and enables a fast search for visible light and other electromagnetic signals emitted during the collisions. This new method could be instrumental in preparing the field for the next generation of observatories.

Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental laws of physics, including Albert Einstein's general relativity. Researchers compared Einstein's predictions with data from the Dark Energy Survey. Scientists discovered a slight discrepancy that varies with different periods in cosmic history. These results challenge the validity of Einstein's theories for explaining phenomena beyond our solar system on a universal scale.
