Part 6/10:
In response, a recent scholarly paper provides a detailed counter to Penrose's arguments. The authors concede that for any observable effects to emerge from vibrations in the extra dimensions, the energy must be localized—not spread out uniformly. They emphasize that the critical factor is the energy content within a specific volume of spacetime, not the total energy in the cosmos. Creating such localized fluctuations would require extraordinary precision and conditions, making it unlikely we could observe these via current or foreseeable technology.
