The Anhadnaad Universe
Abstract: Current Science considers that 95% universe is made of Dark energy and Dark Matter which are completely unknown entities and can’t be detected directly. Current Science also does not believe in independent existence of Consciousness on its own. It rather consider it as an outcome of electrical interaction in brain cells which means there are as many consciousnesses as the number of brains in the entire universe. But my theory …

Artificial Intelligence–Assisted Reduced-Order Modeling and Stability Control in Granular Couette Flow
Abstract: This study develops a reduced-order and stability-aware modeling framework for dense granular Couette flow by integrating continuum mechanics, bifurcation analysis, and data-driven stability estimation. Starting from coupled governing equations for momentum, granular temperature, and microstructural evolution, the system is nondimensionalized and reduced using a Galerkin projection consistent with shear-driven boundary conditions. This yields a low-dimensional nonlinear dynamical system that preserves the essential coupling between velocity, fluctuation energy, and structural relaxation. …

Plasma Tweeter Loudspeaker - A Singing ARC
Abstract: Plasma arc speaker is a loudspeaker that generates sound without a solid diaphragm by varying the air pressure and utilizing a high voltage arc. It makes sound by heating air that causes air to expand in the same way as in thunderstorm. The grumbles and growls we hear in thunderstorm come from the quick expansion of the air surrounding the lightning bolt due to sudden increase in temperature. This produces …

Evidence for Forward Spin and Reverse Spin Radio Photons
Abstract: We generated alternate spin radio frequency photons by accelerating metallic valence electrons in a wire with half portions of a sine wave. To avoid standing waves from sinusoidal movement, a non-resonating transmitter was built with a non-resonating antenna. An oscilloscope at a second non-resonant receiving antenna 3 wavelengths away from the transmitter detected positive going 180-degree voltage pulses. Reversing the direction of electron excitation in the transmitter antenna caused negative …
