Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Quantum cosmology and loop quantum gravity constitute two intertwined pillars in the quest for a quantum theory of gravity. Quantum cosmology applies the principles of quantum mechanics to the entire ...

For years, physicists treated an Earth-to-space quantum uplink as a beautiful idea that nature simply would not allow. Now a ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Researchers demonstrate that by shaping the spatial and temporal structure of photons, they can engineer customized quantum states suited for next-generation communication, sensing, and imaging ...

Scientists are exploring a revolutionary theory that suggests human consciousness might operate as a quantum hologram, potentially extending across space and time. This concept, which integrates ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...
