WebIn physics, Gauss's law for gravity, also known as Gauss's flux theorem for gravity, is a law of physics that is equivalent to Newton's law of universal gravitation.It is named after Carl Friedrich Gauss.It states that the flux (surface integral) of the gravitational field over any closed surface is proportional to the mass enclosed. Gauss's law for gravity is often … WebThe existence again contradicts the Gauss-Bonnet theorem. Observing the two works, one should be able to conclude that the two proofs using the minimal surface are actually proofs of two special cases when pvanishes: (I) = ˇ=2 in [Cha18]; (II) or = 0 in [ABdL16].
