Gravity Leaking = Dark energy increasing

AI Thread Summary
The discussion explores the concept of gravity leaking and its potential relationship to dark energy and the expanding universe. A new participant suggests that gravity weakening in our universe could correlate with increasing dark energy, possibly linked to parallel universes. However, experienced contributors clarify that gravity leaking is not a widely recognized phenomenon and that an expanding universe can exist without dark energy. They emphasize that any connection between gravity leaking and accelerated expansion is complex and depends on specific mathematical conditions in higher-dimensional models. The conversation highlights the need for a deeper understanding of cosmological theories to accurately interpret these concepts.

Hello everybody, I am new to this forum and cosmology in general.

My knowledge about cosmology and astro-physics is rudimentary :shy: so guys cut me some slack.


From the limited information I know , I feel that phenomenon of gravity leaking might be related to the phenomenon of the expanding universe i.e Increase in dark energy.

As the laws of Thermodynamics state that energy can neither be created nor destroyed , it can be converted into one form or the other and the total amount of energy in A universe always remains constant, combined with the fact that several scientists believe in the existence of parallel universes, can it be that since gravity in our universe is leaking ( or in my understanding getting weaker) that in an another parallel universe, gravity might be getting stronger or dark energy might be decreasing?


So guys am i interpreting this correctly or even asking the right questions or am i totally offbase?

I have a feeling it's the latter, I'm afraid. I've never heard of gravity leaking, and you can have an expanding universe without dark energy.
 
There is no inmediate - or intuitive - link between leaking of gravity and accelerated expansion. Leaking of gravity will arise in models of a 3D-brane embedded in 5D spacetime, with afaik some general assumptions about the quantum behavior of gravity. However, for cosmological models derived from those models, there are several mathematical conditions that must met in order to have accelerated expansion - that basically depend on how the 3D brane is embedded in 5D spacetime, the relation between Planck scales on 4 and 5 spacetime dimensions, and the late-time Hubble parameter. See for example hep-th/0010186.
 
Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...
