I will discuss the recent tensions in cosmology and demonstrate a reconstruction method to find a possible primordial solution. I will also highlight a scalar field potential reconstruction related to the solution obtained. Using similar techniques, I will show that while tensions can be ascribed to new physics, in certain cases, careful tests can reveal possible underlying systematics.
