Join Subatomic Tanvi for a mind-blowing exploration of time reversal in quantum physics! We delve into a fascinating thought experiment where a photon escapes the universe, challenging our understanding of entropy and the very fabric of reality. Could the future influence the past? Get ready to be challenged with this intriguing paradox. We'll break down time reversal using relatable examples like a pool table and subatomic particle interactions, making these complex concepts accessible and engaging. Tune in for a captivating journey into the quantum realm that will leave you questioning everything you thought you knew about time!

Ever wondered how light and matter interact at the subatomic level? Join us on this episode of Subatomic Tanvi as we delve into the fascinating world of Quantum Electrodynamics (QED)! We'll explore the mind-bending concept of particles existing in multiple places at once, learn how QED predicts these interactions using probabilities, and even decipher the "rulebook" of this quantum world – the Lagrangian Density. We'll unravel the mysteries of Feynman Diagrams, visual representations of particle interactions, and discover how they illuminate the bizarre dance of light and matter. Get ready for a journey beyond classical physics, where basketballs become probability clouds and billiards unlock the secrets of the subatomic realm!

Ever wondered what holds the universe together? Join us on a mind-bending exploration of the four fundamental constants that shape our reality. From the Boltzmann constant governing the energy of particles to the Planck constant quantifying the energy of light, the speed of light defining the fabric of spacetime, and Euler's number underpinning exponential growth, these constants are the building blocks of the cosmos. Discover how these seemingly abstract numbers influence everything from the behavior of atoms to the expansion of the universe. Prepare to be amazed as we unravel the mysteries of the universe, one constant at a time.
