Why can't we figure out how strong gravity is?
Why can't we figure out how strong gravity is? Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Of the four fundamental forces of nature, gravity is the one we experience most directly — it's what keeps our feet on the ground and the sun in the sky.
Violating the 3rd law of black hole mechanics in vacuum gravity
June 3, 2026 feature Violating the 3rd law of black hole mechanics in vacuum gravity Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts that black holes obey a set of rules, known as the laws of black hole mechanics. These rules somewhat...
Smart surfaces face zero gravity test in boiling heat experiments
Smart surfaces face zero gravity test in boiling heat experiments Lisa Lock Scientific Editor Andrew Zinin Lead Editor A research team led by Davoud Jafari at the University of Twente, in collaboration with the University of Pisa, has completed a series of parabolic flight experiments to investigate advanced smart surfaces under rapidly changing gravity conditions. Conducted aboard the Air Zero G aircraft operated by Novespace, the campaign integrated additive manufacturing, boiling heat...
Lagrangian Extensions of Newtonian Gravity constrained by Solar System tests
Announce Type: cross Abstract: We explore an extension to Newtonian gravity through a generalised Lagrangian function with the introduction of a second dynamical scalar field. Building on previous research into gravity with variable gravitational coupling, the work derives the complete field equations and applies a weak-field approximation. This leads to an effective post-Newtonian gravitational potential that includes key aspects of relativistic theories.
Entanglement Builds Space-Time. Now "Magic" Gives It Gravity
Entanglement Builds Space-Time. Now “Magic” Gives It Gravity. In 1973, John Archibald Wheeler described the relationship between space and matter in two sentences: “Space acts on matter, telling it how to move.
Super Typhoon Sinlaku triggered atmospheric gravity waves visible from space
Super Typhoon Sinlaku triggered atmospheric gravity waves visible from space A record-early super typhoon sent giant atmospheric ripples into near-space, offering scientists a new clue for tracking powerful storms. - Date: - June 3, 2026 - Source: - NASA Earth Observatory - Summary: - One of the most powerful typhoons ever recorded this early in the Pacific season did more than unleash flooding and extreme winds—it sent enormous ripples all the way into the upper atmosphere.
Topics on Foundations of Physics: From the quantum to the (semi) classical, gravity, thermodynamics, and (or beyond) our possible detections
Announce Type: cross Abstract: The work leading to this thesis focuses on assessing and extending quantum theories in order to explore and test their implications across various regimes -- including thermodynamics, semiclassical and quantum gravity scenarios, and the in principle detectable predictions of such theories. The general motivation stems from a basic desire to understand the world form its very foundations. For instance, how can we bridge the gap between what we observe or...
Late-Time Cosmology and Structure Formation in Quadratic $f(Q)$ Gravity
arXiv:2606.02660v1 Announce Type: new Abstract: We investigate the cosmological evolution associated with the quadratic symmetric teleparallel gravity framework, \( f(Q)=Q+\alpha Q^{2}+\beta \) where the relation \(Q\propto H^{2}\) generates an additional \(H^{4}\) contribution to the Friedmann equation. Using the exact algebraic solution for $H(z)$, we reconstruct the effective dark-energy sector and compare the background evolution with $\Lambda$CDM using Type Ia supernovae, BAO, and...
Show HN: Gravity – interactive solar-system simulator, from Newton to Einstein
Just for fun and self education, I've built this over a weekend to teach myself why orbits exist, not just show planets going around. Something that was never clearly explain to me in school. It opens with a guided tour that builds the idea up step by step: two bodies and the equal/opposite force, inertia (the Sun is removed and Earth just drifts straight), then "an orbit is falling and continuously missing," cosmic velocities with a little rocket, Voyager 1 & 2's real gravity assists (the...
