In the last bunch of posts, I’ve explored the Activation Layer, my name for the 3D hypersurface within 4D spacetime that we exist in. It holds all particles and fields, and all forces and laws such as special relativity and quantum field theory. I discussed how even the observable effects of general relativity is confined within this hypersurface, although the principles of general relativity must deform the hypersurface within 4D spacetime. While my main interest has been discussing how this activation layer constrains elementary particles and their interactions, in the last post I explored what this idea means for our cosmos. In particular, I believe the Big Bang would look different–it would look like a surface shell rather than what scientists say about a spherical expansion from a core Big Bang point. I believe there should be a variety of ways to test this with astronomical observations (see this link: https://agemozphysics.com/2024/10/22/our-hyperspace-within-4d-spacetime-does-not-violate-special-relativity-part-ii/). We already have observations that appear to point to the hypersurface model–in this post, I want to examine why scientists still think these observations point to the spherical expansion model of the Big Bang.
Observations of the cosmic microwave background radiation (CMB) shows a uniform distribution and velocity in every direction. I made the point that this would verify that the activation layer hypersurface is the correct representation rather than the spherical volume expansion of the Big Bang that is currently the accepted thinking. The CMB is almost perfectly isotropic everywhere, and not only that, the James Webb telescope is not seeing significant variation for the maturity of galaxies in all directions. As I posted in the above link, both of these are direct consequences of a hypersurface activation layer Big Bang, and should be further confirmation that the Big Bang is not spherical.
However, it appears that scientists explain the cosmic isotropy as present even in the initial moments of the Big Bang, and that the observable expansion both of the spacetime dimensions and its contents would retain their isotropy to the present day. The claim is that this isotropy is why there is no detectable direction pointing to the original Big Bang region from our point of view on earth and why instead the Big Bang remnants show up as the CMB. As I mentioned in my previous post, I don’t see how this could be true–if there is an expansion from a Big Bang point, 4D spacetime will have an outflow of galaxies from that point and in a Euclidian representation of 4D spacetime, there is no question that outflow direction would be detectable. Of course, the universe expansion is not Euclidian; instead, by general relativity, the dimensions of the universe will curve dramatically. The accepted argument is that this curvature will compensate for the outflow from the Big Bang point to make it appear isotropic and radiation will appear to be omnidirectional. To me, the problem with this approach is that photons from observation sources also are affected by this dimensional curvature, and thus dimensional curvature will not affect what is observed! If there is an outflow source, that will look the same as if the observer saw the Big Bang in Euclidian space!
Of course, general relativity does make a mess of this line of thinking, since not only is there a dimensional curvature, but there is also a substantial effect on the motion of the galaxies within the expansion. Nevertheless, I can see no way at all that observations of the early universe, a few hundred million years after the Big Bang, would not reveal the direction of galaxy outflow. If the isotropic spherical expansion is the correct model, we should see the direction of the Big Bang core. Perhaps we currently cannot go back far enough in time to see this core, but there will be a region of space with fewer deep red-shifted galaxies–a consequence of those galaxies having a smaller velocity relative to our observer’s position on earth. I also just simply do not see how the CMB can be nearly perfectly homogenous and isotropic in a spherical Big Bang. No matter what kind of Big Bang expansion curvature we have, the CMB should be globally anisotropic in a spherical expansion. It is not, and that result is exactly predicted by the hypersurface model of the cosmos.
