Description
The Weyl potential, which is the sum of the spatial and temporal distortions of the Universe's geometry, provides a direct way of testing the theory of gravity and the validity of LCDM. In this talk I will first present a methodology to directly measure the evolution of this potential from galaxy-galaxy lensing measurements with a minimum amount of assumptions. I will then show the results using the Year 3 data from the Dark Energy Survey, and also how these measurements change once we include data from the Dark Energy Spectroscopic Instrument.
