WebNov 4, 2024 · in Newtonian gravity, the gravitational field obeys the equation. ∇ 2 ϕ = 4 π G ρ. David Tong in his notes on general relativity claims that this equation works well when ρ is not a function of time, but when ρ depends on time, then a change in ρ would result in a change in ϕ throughout all of space. But this equation is a local ... http://web.mit.edu/course/8/8.02-esg/Spring03/www/8.02ch24we.pdf
