Explores luminosity distance, the Einstein field equation, Stephen Hawking's contributions, and the cosmological principle, among other cosmological concepts.
Explores relativistic kinematics, including the transformation of coordinates, the Lorentz transformation, and the invariance of the space-time interval.
Explores the transformation of Newton's second law in the context of Einstein's relativity and Lorentz transformations, discussing the equivalence of physical quantities in different inertial frames.
Explores the worldline action of a charged particle in Minkowski spacetime, covering 4-vectors, intervals, Lorentz invariance, and charged particles in EM fields.
Explores the impact of COVID-19 on astronomy and the European Southern Observatory, delves into the Friedmann equations, and discusses the concept of dark energy.
