Major survey results now hint that dark energy has evolved across cosmic history, raising questions about the standard model ...

“The gravitational quantum metrological triangle may have applications in metrology and could be used to investigate the relation of the Planck constant to fundamental particle masses,” the ...

{r^2}\) The constant of proportionality is the universal gravitational constant ("big G") which equals \(6.674\times{10^{- 11}}N{m^2}k{g^{- 2}}\). Overall this equation is simpler than it looks as ...

Artificial intelligence could offer a powerful pathway to supercharge our ability to "hear" the universe, according to new ...

According to Einstein, the constant would be a repulsive force that counteracts gravity, keeping the universe from collapsing in on itself. Einstein later discarded the idea when astronomical ...

Earth’s gravity isn’t constant—it changes subtly all the time as mass shifts around the planet. Geological processes like tectonic activity, glaciers calving, or aquifers draining can ...

However, the model also predicts a small, positive cosmological constant—consistent with the observed accelerated expansion ...
