Cosmic limits come from physics, not imagination

Even with “insane” energy sources, relativity blocks faster-than-light travel, so space exploration is bottlenecked by light-travel time; similarly, brain-pattern instincts don’t create new realities, only interpretations constrained by equations.

Infinite energy can’t defeat speed-of-light

Relativity makes mass grow without bound as velocity approaches light speed, requiring infinite energy to reach it; therefore higher propulsion energy changes everything else but cannot eliminate causality-distance limits.

Fractal “similarity” supports laws, not identity

Universe and brain can both be fractal yet require different mathematical forms; that shared fractal structure points to common underlying laws, while different fractal math blocks claims of direct physical linkage or simple simulation evidence.
