Universal Characteristic-free Resolution of Singularities, I

We prove that for any singular integral affine variety $X$ of finite presentation over a perfect field defined over $\mathbb{Z}$, there exists a smooth morphism from $Y$ onto $X$ such that $Y$ admits a resolution. That is, there exists a smooth scheme $\tilde{Y}$ and a projective birational morphism from $\tilde{Y}$ onto $Y$, followed by a smooth morphism from $Y$ onto $X$. Our approach differs fundamentally from existing methods, as we neither restrict to any specific singular variety nor fix the characteristic. Instead, we design a {\it universal} blowup process that {\it simultaneously} resolves all possible singularities, and, our method is entirely characteristic-free.
