Gravity, what is it? No one knows exactly *what* gravity is. We can predict its behaviors but not much else, because even relativity’s only an incomplete view. We don’t know exactly what the essence of gravity is, nor the answer to other conundrums like why gravity is so weak compared to the other three forces, and to be frank, speculation aside, we may never know the answer to this haunting riddle, the riddle that has haunted scientists since the days of Galileo and Newton, what is gravity?
This video by the excellent as always John Michael Godier elaborates more on this subject: https://www.youtube.com/watch?v=6MA7jLKnQ4c
I highly recommend it.
