The same physics that could extend human life and expand our reach also gives us tools for self-destruction. The challenge is whether our judgment can keep pace with our power.
Kaku suggests that the human brain functions primarily as a sophisticated future-prediction machine, utilizing the cerebral cortex to constantly simulate upcoming scenarios to ensure survival.
Biological immortality is theoretically possible through the manipulation of telomerase to stop the cellular aging clock, though scientists must first learn to isolate this process from the mechanics of cancer.
String theory attempts to unite the fundamental forces of nature into a single equation, positing that all subatomic particles are simply different vibrations of strings in an eleven-dimensional universe.
