According to Kaku, the basic physics of invisibility has been demonstrated sufficiently; it's merely an engineering problem now, he said. Laboratories around the world have shown that microwaves can be wrapped around an object to render it invisible. Within a decade or so, the ability to make an object "totally vanish in one color" will be possible, Kaku noted. Sometime after that, a cylinder made from 'metamaterials' may allow soldiers to become invisible, he said.
Kaku spoke about teleportation, pointing out that researchers have already teleported a photon from one Canary Island to another over a distance of 100 miles. In the next decade, he theorized, water molecules will be teleported and then complex molecules like DNA.
Kaku shared the latest info on a kind of telepathy. He said MRI brain scans have shown with a 98% accuracy rate when a college student is lying. He speculated that using brain scans to read a person's mind is not too far away. Kaku also discussed precognition, and Art shared his own precognitive experience regarding a car accident.
Kaku also covered global climate change, alternative energy, psychokinesis, perpetual motion machines, SETI, and the potential effects of WR 104, a binary star located 8,000 light years away. Experts fear that when the star explodes it could send a beam of destructive gamma-ray radiation towards Earth. Kaku said the star may have already exploded.
