I conducted research on cosmology under the supervision of Mr. Sandip Roy, a PHD student at Princeton university.
I looked closely at the homogeneity and isotropic universe, derived the Friedmann equations using Newtonian physics and worked with differential equations to solve the Friedmann equations, used numpy and python to simulate physical systems and the rate of acceleration of the universe by inputting and solving the Friedmann equation. I published a research article about the accelerating universe and Friedmann equation.
