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.

  • We're in the middle, or thereabouts, of the universe's Stelliferous era.
  • If you think there's a lot going on out there now, the first era's drama makes things these days look pretty calm.
  • Scientists attempt to understand the past and present by bringing together the last couple of centuries' major schools of thought.

Physicists probe why the Universe exists and has matter

A new study rocks prevailing theories on antimatter in the early Universe.

NASA
  • Scientists from around the world teamed up to study the properties of neutrons.
  • They were able to achieve extremely precise measurements of electric compasses in neutrons.
  • The results challenge current theories of why antimatter and matter didn't destroy each other in the early Universe.

  • Researchers have been trying for over 60 years to detect dark matter.
  • There are many theories about it, but none are supported by evidence.
  • The mass-energy-information equivalence principle combines several theories to offer an alternative to dark matter.

Intellectual dark matter: What is it, and why is it meaningful?

Throughout history, we find knowledge that can't possibly be documented, but still it exists.

  • You're probably familiar with the concept of physical dark matter, but what about intellectual dark matter?
  • In a similar way to the universe's dark-matter makeup, our vast body of knowledge contains a significant amount of information that can't easily be described in words.
  • If knowledge was passed down only through writings or direct experience, society would crumble.
