Recently in pbs spacetime I saw a video about entropic gravity, where some of the researchers in this field seems to explore wether gravity is just an entropic force resulting from thermodynamics. It was an entersting perspective I haven't heard of.

Who knows, maybe in a distant future we'll that that 4th fundamental force is not so fundamental after all.
