| الوصف: | We reveal a hidden aspect of scale-invariant actions that allow matter to couple with a dilaton field: $\ $the dynamics of the dilaton can be used to induce variations in Planck's quantum of action $\hbar$ and the speed of light $c$. This mechanism for generating variable $\hbar$ and $c$ in $\textit{curved}$ spacetimes offers novel insights into the origin of late-time cosmic acceleration, bypassing the need for dark energy. Comment: 6 pages. No figure |
