Lectures related to Gravitational Effects: Action Evaluation and Wavelength Shifts

Delves into gravitational instability, structures formation, and CMB temperature, exploring the inhomogeneities in the Universe.

Explores modified gravity theories to unify inflation and dark energy in cosmology.

Explores the detection of gravitational waves, focusing on the first observation of a binary black hole merger and its implications for astrophysics.

Explores physics scales, measurements, historical definitions of meter and kilogram, time definition, and scalars and vectors.

Introduces special relativity, covering time dilation, mass-energy equivalence, and thermodynamics, including ideal gas laws and phase transitions.

Discusses defining tensors, space-time dimensionality, and challenges in formulating a relativistic theory of gravity.
