For over a century, scientists have thought of time as a fundamental property of the universe. But the more researchers seek to understand time’s ultimate nature and the mechanics behind its emergence ...

Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples ...

For those who see the world as a dark place, the universe seems to offer little solace. According to current estimates, approximately 70% of the stuff that makes up the cosmos consists of dark energy, ...

Abstract: Dimension reduction has notably emerged in solving large-scale multi-objective optimization problems (LSMOPs). Nevertheless, the determination of the latent dimension after dimension ...

Braneworld scenarios posit that our observable universe is a four-dimensional “brane” embedded in a higher-dimensional “bulk”, with gravity and other fields propagating differently across these ...

Abstract: Optimization-based visual-inertial simultaneous localization and mapping system (VI-SLAM) focuses on the establishment of the loss function using both inertial and visual constraints.
