Energy Quote by John D. Barrow
““It is the cosmological vacuum energy that contributes a repulsive lambda force to the gravitational force of Newton.””
About This Quote
Source Lecture: Cosmology Seminar, Cambridge University, 1998
The cosmological constant (lambda) acts as a repulsive force that counteracts gravity, influencing the expansion of the universe.
In simple terms: Lambda provides a repulsive effect that opposes gravity, affecting cosmic expansion.
