Just by thinking in the 4th dimension, a higher level of consciousness, Einstein found that time and space are not absolute but relative.
Another part of his wisdom and genius was calling it a theory, thereby taking off the pressure, and giving people as much time as they needed to explore and make up their own minds.
What we know and understand in 3D, looks very different in the 4D to 11D space that we are starting to become more aware of as we evolve from a Type-0 to a Type-1 civilisation on the Kardashev Scale, over the next 100 years.
Michio Kaku makes this physics accessible to ordinary lay persons (like me) on YouTube, and in his books "Hyperspace" and "Physics of the Future". Michio Kaku points out that is is only possible to properly explain gravity, electromagnetism, strong nuclear, and weak nuclear forces in the 4D to 11D space where they become much simpler.
It would seem the "Physics of the Future" is intimately linked with what Stanislav Grof outlines as "The Psychology of the Future" (on YouTube).
