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.Omega137 said:Can anyone help me with explaining what is Brane Tension (t_3)

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.Omega137 said:I don't know if am I right; but my idea is that the Brane Tension is similar to a Cosmological constant on the Brane...
Brane tension t3 is a fundamental property of a brane, which is a theoretical construct in string theory. It represents the energy density of the brane and is an important factor in determining its behavior and interactions with other branes and particles.
Brane tension t3 is typically measured in units of energy per length, such as joules per meter. In theoretical calculations, it can also be expressed in terms of the fundamental Planck energy.
Brane tension t3 plays a crucial role in string theory, as it determines the dynamics and properties of branes. It also has implications for the behavior of particles and forces in the universe, and can potentially help explain the observed phenomena in cosmology and particle physics.
Brane tension t3 is specific to branes and the concept of extra dimensions in string theory. It is different from other types of tension, such as surface tension or tension in materials, which are based on different physical principles.
At this time, there is no experimental evidence for branes or their tension in string theory. However, researchers are actively working on ways to test and potentially observe the effects of brane tension and other aspects of string theory through particle accelerators and cosmological observations.
