Non-singular bouncing cosmology in $f(T, \mathcal{T})$ gravity with energy condition violations
The singularity and inflationary problems have posed significant challenges for understanding the universe's origin and evolution. Bouncing cosmology has emerged as a promising alternative to standard cosmological models, offering a non-singular approach to early universe dynamics by facilitating a "bounce" rather than a singular beginning. In this study, we explore the feasibility of modeling specific bouncing scenarios within the framework of $ f(T, \mathcal{T}) $ gravity, allowing for a comp…

How Switzerland’s Solar Train Tracks Could Reshape Renewable Energy | Happy Eco News
Switzerland is testing solar train tracks to generate clean energy using unused rail space. These removable panels could power 300,000 homes, create jobs, and reduce land use. Countries like South Korea and Japan are watching closely. If successful, the system could offer a new way to meet global energy demands.Switzerland is testing solar train tracks to generate clean energy using unused rail space.
