How your immortal consciousness will travel the universe

Someday we'll beam to the moon for afternoon tea, and be back in New York for dinner.

  • In about 100 years, theoretical physicist Michio Kaku believes we'll explore the universe as pure consciousness — traveling at the speed of light, looking at asteroids, comets, meteors, and eventually the stars. "All of this within the laws of physics," he says.
  • Through recent brain imaging, we know know that the prefrontal cortex of teenagers is fully formed. This induces them to take risks. Also, when guys who talk with pretty girls, we also know it's that blood drains from their brains. Well, their prefrontal cortex. This makes them liable to act "mentally retarded."
  • The Connectome Project will map the entire brain in about 100 years.

Michio Kaku: Mental communication and infinite knowledge are on the horizon

Soon we'll be able to blink and instantly go online via computer chips attached to our eyes.

  • Eventually computer chips, theoretical physicist Michio Kaku avers, will cost a penny, which is the cost of scrap paper. They'll be so pervasive, they'll even be attached to your eyeball.
  • They'll be in your contact lens, allowing you to blink and go online — you'll have access to the internet and will be able to access the knowledge stored on the internet.
  • In the future, Kaku says, we'll be able to convey emotions and memories to one another another via "brain net." This will render emojis and current forms of entertainment, such as sound-and-screen movies, obsolete.

Has a black hole made of sound confirmed Hawking radiation?

One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole."

  • Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
  • Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
  • A scientist has built a black hole analogue based on sound instead of light.

Something is producing weird orbits in the Kuiper belt — is it 'Planet X' or something else?

Some have suggested that there is no hidden giant out there.

  • Some objects at the edge of our solar system have unusual orbits — they cluster together suggesting a large celestial body is pushing them close together.
  • Instead of a massive unfound planet, it may be the gravitational pull from an equally massive disc of small, icy objects.
  • Researchers created a model of such a disc that explained everything.

Nobel winner claims lasers can make nuclear waste safe

  • Gérard Mourou has already won a Nobel for his work with fast laser pulses.
  • If he gets pulses 10,000 times faster, he says he can modify waste on an atomic level.
  • If no solution is found, we're already stuck with some 22,000 cubic meters of long-lasting hazardous waste.
