The Einstein field equations is the set of 10 equations that describe the fundamental interaction of gravitation as a result of spacetime being curved by mass and energy.

To describe the background of the spacetime we have to look at how general relativity developed. Problem of action at distance and speed of light Aristotle believed that force could only be applied by contact; force at a distance being impossible. Gravitational Motion by Instant Action at Distance. Newton and other scientists had always been bother...

Using spin polarized density functional theory (DFT) based calculations, combined with ab-initio molecular dynamics simulation, we carry out a systematic investigation of the bimetallic Ni$_{13-n}$Ag$_n$ nano clusters, for all compositions. This includes prediction of the geometry, mixing behavior, and electronic properties. Our study reveals a ten...
Pulsar Wind Nebulae (PWNe) represent the most numerous population of TeV sources in our Galaxy. These sources, some of which emit very-high-energy (VHE) gamma-rays, are believed to be related to the young and energetic pulsars that power highly magnetized nebulae (a few $\mu$G to a few hundred $\mu$G). In this scenario, particles are accelerated to...
