  • 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.

  • 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.

  • Columbia University astrophysicists discovered the cause of the unusual glow coming from regions of space with black holes and neutron stars.
  • The researchers ran some of the largest computer simulations ever to reach their conclusions.
  • They found that turbulence and reconnection of super-strong magnetic fields are responsible for the light.

New study says cosmic acceleration and dark energy don't exist

An Oxford scientist claims a Nobel-Prize-winning conclusion is wrong.

NASA
  • Paper by Oxford University physicist Subir Sarkar and his colleagues challenges how conclusions about cosmic acceleration and dark energy were reached.
  • Physicists who proved cosmic acceleration shared a Nobel Prize.
  • Sarkar used statistical analysis to question key data, but his methodology also has detractors.

  • An astrophysicist and cosmologist Dr. Farnes published a paper while at Oxford University with a novel explanation for dark energy and dark matter.
  • His theory claims to explain the missing 95% of the observable universe by the existence of "dark fluid".
  • This fluid has negative mass, repelling other materials.
