Can anyone help me with explaining what is Brane Tension (t_3)

I'm reading an article on cosmology, and I need to understand it...

Well, it's basically a tension (like a tension on a string) that wants to cause the brane to contract.

Well, for that to be the case, it would need to be independent of scale. That is, if I stretched the brane (via cosmological expansion), the tension would remain the same. This may be the case, but I'm not so sure.
 

Thread 'Gravitational self-interaction: another attempt to replace Dark Matter'

https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...

Thread 'Twistors and celestial holography'

Many of us have heard of "twistors", arguably Roger Penrose's biggest contribution to theoretical physics. Twistor space is a space which maps nonlocally onto physical space-time; in particular, lightlike structures in space-time, like null lines and light cones, become much more "local" in twistor space. For various reasons, Penrose thought that twistor space was possibly a more fundamental arena for theoretical physics than space-time, and for many years he and a hardy band of mostly...
