3 mind-blowing space facts with Neil deGrasse Tyson

Tyson dives into the search for alien life, dark matter, and the physics of football.

  • Astrophysicist Neil deGrasse Tyson joins us to talk about one of our favorite subjects: space.
  • In the three-chaptered video, Tyson speaks about the search for alien life inside and outside of the Goldilocks Zone, why the term "dark matter" should really be called "dark gravity," and how the rotation of the Earth may have been the deciding factor in a football game.
  • These fascinating space facts, as well as others shared in Tyson's books, make it easier for everyone to grasp complex ideas that are literally out of this world.

Planet Nine will be discovered in the next decade. Here’s why.

The planet that we are searching for is a little bit smaller and closer than we originally thought.

  • Years ago, California Institute of Technology professor Konstantin Batygin was inspired to embark on a journey of discovering what lurked beyond Neptune. What he and his collaborator discovered was a strange field of debris.
  • This field of debris exhibited a clustering of orbits, and something was keeping these orbits confined. The only plausible source would be the gravitational pull of an extra planet—Planet Nine.
  • While Planet Nine hasn't been found directly, the pieces of the puzzle are coming together. And Batygin is confident we'll return to a nine-planet solar system within the next decade.

Scientists discover a new way to search for dark matter

Have we already found dark matter? It may be hiding in existing data, says a study.

  • A new study proposes to look for dark matter during the process of scattering.
  • The scientists think dark matter indicators could be hiding in existing data.
  • The researchers aim to adapt current experiments to find the elusive particles.

Ask an astronomer: What was Einstein’s most mind-blowing discovery?

Do space and time really exist? NASA astronomer Michelle Thaller looks at the implications of Einstein's famous equation E=mc2.

  • NASA astronomer and science communicator Michelle Thaller explains that the real brilliance of Albert Einstein is that he was able to bridge ideas that appeared to others to be in different realms.
  • The thing Einstein is most famous for is the equation E=mc2. Thaller explains why that equation is so mind-blowing: Pure energy and matter are the same thing. That means, as humans, we are both made of matter and of pure energy, and as pure energy, we would not experience space or time.
  • "I think that, once we really understand this, we're going to be in for some very difficult truths to accept," says Thaller. "It may be that there is no space or time as we know it, really."

Gamma-ray space telescope study may have spotted dark matter

New study of gamma rays and gravitational lensing points to the possible presence of dark matter.

NASA
  • Analyzing data from the Fermi Gamma-ray Space Telescope, researchers find hints of dark matter.
  • The scientists looked to spot a correlation between gravitational lensing and gamma rays.
  • Future release of data can pinpoint whether the dark matter is really responsible for observed effects.
