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.

​Stephen Hawking believed humans should go to moon before Mars, says Buzz Aldrin

The Apollo 11 astronaut was recently awarded the Stephen Hawking Medal for Lifetime Achievement.

  • Buzz Aldrin is an Apollo 11 astronaut who was the second man to walk on the moon.
  • NASA currently plans to send humans back to the moon and establish a "deep space gateway" that would eventually send astronauts to Mars.
  • Meanwhile, private companies, such as Mars One and SpaceX, are planning voyages to the Red Planet.

How to detect life on Mars

If life exists on Mars, there's a good chance it's related to us, say researchers.

When MIT research scientist Christopher Carr visited a green sand beach in Hawaii at the age of 9, he probably didn't think that he'd use the little olivine crystals beneath his feet to one day search for extraterrestrial life.

SpaceX is launching NASA's $80 million Deep Space Atomic Clock tonight

NASA JPL takes a first step toward a GPS for space.

  • Spacecraft have no independent navigation systems onboard. They rely on navigation instructions sent from Earth, which can take about 40 minutes to reach them.
  • The presence of an onboard atomic clock would radically streamline spacecraft navigation and is crucial to autonomous space exploration missions.
  • A SpaceX Falcon Heavy rocket will take NASA's Deep Space Atomic Clock up for a year-long mission starting June 24, 2019.

Always dreamed of flying? On these moons, you can.

There are places in our solar system where you can fly.

  • Both the moon and Mars have a weaker surface gravity than the Earth does. The result? You don't weigh as much on either celestial body as you do here.
  • On a moon called Titan that orbits Saturn, the gravity isn't as strong as Earth's, but the atmosphere is much thicker. In this world, it would be possible to strap wings to your arms and fly around.
  • On a low-gravity moon called Miranda, just off the space coast of Uranus, there are cliffs that are many miles high. It would be possible to jump off a cliff here and fall very gently to the bottom.
