String field theory co-founder Michio Kaku did not even try to explain his controversial yet undeniably brilliant cosmological theory of everything during his interview on Reddit, beyond this analogy:

"In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11 dimensional hyperspace."

(The "Mind of God" is what Stephen Hawking said we would understand once we completed a theory of everything.)

While Kaku's cursory approach annoyed some Redditors (the top-voted response brings up problems with string field theory like its lack of testable theses that he did not address), it allowed him to discuss a wide array of fascinating topics he has covered in his further research.

Kaku's media tour is meant to promote his new book, "The Future Of The Mind."

Some highlights from Reddit:

On coming breakthroughs:

"Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.

"I think, in the coming years, we will have a brain pacemaker that can stimulate the memory of people with Alzheimer's disease. They will be able to upload simple memories of who they are and where they live. Beyond that, we will be able to use electronics to upload vacations we never had, perhaps. And the internet itself will be a brain-net of emotions and memories.

"The 20 century was the century of physics, with computers, lasers, TV, radio, GPS, the internet, etc. Physics, in turn, has made possible that can probe biology. So I think the 21st century will be the century of physics and biology, esp. biology that can be explored via physics. So the future belongs to nanotech, biotech, AI, and quantum physics."
