  • 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.

  • Researchers find out how binary star systems produce gamma ray bursts.
  • Gamma ray bursts are the brightest explosions in the Universe.
  • Tidal effects created in a binary system keep the stars spinning fast and create the bursts.

What can old stars teach us about the birth of our galaxy?

These needles in the vast galactic haystack take more effort to find, but they help piece together our origins.

  • With billions of stars in our galaxy, why should astronomers seek out the oldest ones?
  • Age-dating stars is a complicated process, so astronomers use chemical compositions, telescopes, and prisms to determine the age of these ancient stars.
  • Some telescopes used for this purpose are in extremely remote places, where you can observe the bright band of the Milky Way with the naked eye.

  • Astrophysicists from Russia propose a theory that says dark energy doesn't exist.
  • Instead, the scientists think the Casimir Effect creates repulsion.
  • This effect causes the expansion of the universe to accelerate.

  • A new study from Princeton physicists successfully uses boron powder to control nuclear reactions in plasma.
  • Creating plasma can lead to an unlimited supply of energy.
  • The new method is cheaper and less dangerous than previous approaches.
