Could an extra creasing in space time offer a better fit for dark matter and dark energy.

[highdimensionman]

What if space time had an extra creasing in space where by gravitational energy was drawn in from outside the galaxy stretching space-time between galaxies and amplifying galactic gravitation. if this extra space time feature does exist it should be quite easy to test for it against the standard model with real world data to see if a better fit can be sought. whether or not expansion is need still isn't a better fit what true scientists are looking for and this thought is compatible with and is just an extension of Eisenstein space-time so I'm not going back to Newton or Tesla for this idea. it's an onwards with Eisenstein idea not a back to the drawing board idea.

What do you think about this possibility.

What do you mean by  "an extra creasing in space" and what makes you think such a thing could exist?

Dark matter and Dark Energy are two very different theories. One relates to galactic spin; the other to the expansion of space.

How would your idea of a "extra creasing in space" relate to either phenomenon ?

Like when you have a sphere whose surface is 'flat'?

Ωtot is doubled to reflect the different overdensity constant, Δc, as in the standard ΛCDM model verses that used for galaxies.

Compare this to the currently accepted cosmological model for the Universe, ΛCDM model, where Ωm = 0.3 and ΩΛ = 0.7; in this case, Δc ≈ 100 (at a redshift of zero; the value approaches the Einstein-de Sitter value with increased redshift). Nevertheless, it is typically assumed that Δc = 200 for the purpose of using a common definition, and this is denoted as r200 for the virial radius and M200 for the virial mass.
