Gravitational anomalies exist near black hole mergers, but they are generally understood as extreme manifestations of gravity predicted by General Relativity (GR), rather than violations of physics. These mergers are the most energetic events in the universe, generating massive ripples in spacetime called gravitational waves. Explore whether gravitational anomalies occur during black hole mergers…

One of the best-performing models in cosmology is also one with the least physical rationale behind it. Columnist Leah Crane says this leaves us with a puzzle that could make or break physics as we know it

As the Northern Hemisphere progresses through the balmy days of Spring, it's a perfect time...

A long-standing cosmic mystery is beginning to yield new clues as researchers uncover a strikingly consistent pattern in the behavior of high-energy particles traveling across the universe. More than 100 years after their discovery, cosmic rays continue to puzzle scientists. These extremely energetic particles travel across the universe from distant and powerful sources. The DAMPE [...]

Based on the underlying logic of the matter-energy cycle in the universe, this study constructs a true infinite void field matter-energy evolution model, systematically explaining the complete cycle from void field creation, cosmic evolution, to ultimate fate. The model takes the true infinite void field as the theoretical foundation, defines chaotic energy as the primordial material of all cosmi…

Our Moon is still guarding its secrets decades after the last of the Apollo missions lifted off the lunar surface. Lunar scientists still puzzle over just when and how a giant Earth impactor formed our Moon, completely altering our early Earth in the process.

Nature Astronomy, Published online: 04 May 2026; doi:10.1038/s41550-026-02855-0 JWST has produced some of the first spatially resolved spectroscopic observations of massive quiescent galaxies less than 2 Gyr after the Big Bang, revealing a kinematically unique galaxy that shows little-to-no rotational support.

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize the cosmological constant in ways previously unrecognized. The cosmological constant is a term physicists use to describe the energy pushing the universe to expand faster over time. Despite its simple definition, it represents one of the deepest unsolved [...]

A newly identified bubble of reduced galactic cosmic ray (GCR) flux appears to align with the Sun’s magnetic field, indicating an unexpected interaction between the Sun and Earth that the Moon passes through as it orbits. Credit: Shang et al., 2026 , https://doi.org/10.1126/sciadv.adv1908

The American Association for the Advancement of Science (AAAS) has elected Dr. Jennifer Lotz, director of the Space Telescope Science Institute (STScI) in Baltimore, Maryland, as a 2025 Fellow of the AAAS. She is being honored for distinguished leadership and scientific contributions to astronomy, particularly insights learned about the early universe from gravitational lensing observed by the gr…

The Vela Supercluster, in our Milky Way's Zone of Avoidance, is competing gravitationally with other superclusters for the attention of local galaxies.

Meet Loki The post There’s A Dwarf Galaxy Hidden Inside the Milky Way appeared first on Nautilus .

For years, astronomers have been staring at the mysterious little red dots from the early universe. Now a new clue makes the mystery even more intriguing.

Early galaxies were star-forming machines, gobbling up gas and spitting out stars with a furious intensity. A new model helps explain why things were so different back then.

We develop a closed variational framework in which physical reality is defined as the unique configuration selected from the set of stationary solutions of a universal quartic functional. In this setting, existence is not postulated but derived: only configurations satisfying the variational equation and selected by a global decisional functional belong to physical reality. Within this formal str…

Some stars hide a strange ingredient in their atmospheres: the remains of a planet they devoured. It turns out to be more common than expected.

Check out the Universe in a Black Hole Merch at the Space Time Merch Store https://www.pbsspacetime.com/shop. Kurt Gödel discovered a solution to General Relativity that allows time travel without any exotic physics, revealing that the theory doesn’t actually guarantee a consistent chain of cause and effect. His “Gödel universe” shows that under certain conditions, the […]

This paper formulates the dark-sector synthesis of the Variational Backbone and Regime Closures program. The aim is not to fit cosmological data, nor to add a dark-matter Lagrangian or a bare dark-energy term. Instead, we show how a dark gravitational source can be extracted from the same fixed backbone that also produces the mass readout. Starting from the inherited scalar backbone E[g, IR, II, …

At the centre of a water molecule, tucked inside its hydrogen atom, there is usually just a single proton. Nothing else. But in a small fraction of the water on Earth, and in comets and asteroids scattered throughout our solar system, that proton has a neutron companion, making the hydrogen heavier, turning H2O into something denser and slightly more sluggish: deuterated water, or HDO. The ratio …

本书试图回答一个极其基础但长期被遮蔽的问题：宇宙究竟是「由什么构成的」，还是 「 如 何 生 成 自 身 的 」 ？ This book attempts to answer a foundational question that has long been obscured: Is the universe composed of things, or does it generate itself? The answer we develop here is that generation — not substance — is the universe's primary mode of being. 在经典科学传统中，宇宙被理解为一个由基本实体组成的系统，遵循外在规律并在时间中 演化。从牛顿经典力学到场论与标准模型，这一范式构成了现代科学的基础结构，其核心假设 可 概 括 为…
