Discovery: What would you see and experience if the clocks rolled forward 50 years? Physicist and 2057 host Michio Kaku is here for the next hour to answer your questions about our possible futures. So ask away!

Dr. Kaku: Welcome to everyone who's dialed into Discovery.com. I hope that the series 2057 has given you an exciting yet scientifically authentic vision of the next 50 years.

andres: What about advances in neurotechnology? Will we be able to achieve technological telepathy?

Dr. Kaku: I think a limited form of telepathy may be possible in the coming decades. At the very minimum, we should be able to create a dictionary of thought. That is, a one to one correspondence between certain MRI and EEG patterns, and certain specific thought patterns. However, at the present time, we cannot even reliably detect when a person is telling a lie. But in the next decade, we will be able to establish that certain thoughts like love, hate, lying, or telling the truth, correspond to certain neural pathways as detected by MRI and EEG scans. So I don't think we will have perfect telepathy, but I do think we will eventually construct a dictionary of thought.

yankeesfan1: What exactly is Einstein's theory of everything?

Dr. Kaku: Einstein unified matter and energy as well as space and time. His goal, however, was to go beyond that. He wanted to unify all the physical forces of the universe. Including gravity and light. He failed. He spent the last 30 years of his life chasing after a theory of all physical forces. Today, we think we have a candidate for the theory of everything which might allow us to "read the mind of God." The theory is called string theory. It states that all the particles of nature are nothing but tiny vibrations on a small rubber band. So physics is the laws of harmonies of the strings, chemistry is the laws of melody of the strings, the universe is a symphony of strings, and the "mind of God" is cosmic music resonating through eleven-dimensional hyperspace.
