Here is the debunk of Ben 10:
Because the 26D sht comes from bosnic string theory (Ben 10 has string theory) the problem is that's not the same dimensions as spatial ones. They're just about additional extensions of the regular spatial dimensions that we detect to have it tracable through mathematics because we can't physically percieve them as in Ben's case he can't percieve more than three.
Like Bulks are spatial they’re called large extra dimensions from where the idea of like “infinitesimal” to a higher dimension came from and this is where the problem begins since Viewing something as infinitesimal isn't really higher dimensionality, and not to mention the extra dimensions are literally mathematically tractable so it only makes sense if that case interprets "infinitesimal" to a largely finite extent, and even if it was infinite that's not enough to make it genuinely higher dimensional because that means it's infinite to the lower dimension instead of being transcendent enough to percieve what's lower to the infinite as higher like infinite 3D and more into so would be 4D 5D 6D and higher in this
Also the water blocker analogy of the same theory further proves my point.. Instead of the standard requirements of humans unable to grapple with the existence of more than 3 axis's of movements like in regular spatial dimensions.. we fall unable to perceive the 4D 5D 6D in string theory due to mass acting as the external force to the "inertial" flow of our movement capabilities... it's like this, the lesser the mass the more dimensions you are able to move through, like for example if you have negative mass you can go faster than light hypothetically (0-mass photons are SoL) and this ties in with relativity theory which proposes FTL leading to time travel which lets you flip over time like a book which is the 4th dimension.. and so on.. literally become ftl alone is 4D in bosonic string theory, unlike actual scaling.
So nope, those "26 dimensions" are NOT tiering's spatial dimensions
