Click For Summary
Gravity is primarily understood through the lens of general relativity, which posits that massive bodies warp the fabric of spacetime. The discussion highlights that the causes of gravity can vary depending on the theoretical framework one considers. There is a sense of curiosity and frustration regarding the incomplete understanding of gravity, as indicated by the comment about flying a saucer if the causes were fully known. The conversation reflects a blend of scientific inquiry and imaginative speculation. Overall, the complexities of gravity remain a significant topic in physics.

What causes GRAVITY?
 
Physics news on Phys.org
depends of what theory you look at. As of right now, I am pretty sure it's based on general relativity, which says that a massful body warps the fabric of spacetime.

if we knew, id be flying my saucer right now
 

Thread 'Questioning the timescape model'

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
