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.

Scientists discover how to trap mysterious dark matter

A new method promises to capture an elusive dark world particle.

  • Scientists working on the Large Hadron Collider (LHC) devised a method for trapping dark matter particles.
  • Dark matter is estimated to take up 26.8% of all matter in the Universe.
  • The researchers will be able to try their approach in 2021, when the LHC goes back online.

  • A new paper uses string theory to propose a new model of the universe.
  • The researchers think our universe may be riding a bubble expanded by dark energy.
  • All matter in the universe may exist in strings that reach into another dimension.

  • A cosmological model predicts that the expanding Universe could rip itself apart.
  • Too much dark energy could overwhelm the forces holding matter together.
  • The disaster could happen in about 22 billion years.

"Violations" of a Basic Law of Physics Created Mysterious Dark Energy, Propose Scientists

Physicists propose that violations of a fundamental law of physics in early stages of the universe are responsible for the mysterious dark energy.

Physicists have proposed that one of the fundamental laws of physics, the law of conversation of energy, had a “violation” in the early stages of the universe. This could explain the issue of the “cosmological constant” which has troubled physics since Einstein and has been linked in recent physics to the emergence of the theorized dark energy.
