  • Science fiction has long speculated about parallel universes and what they may be like.
  • Researchers have devised new experiments to look for how a mirror universe may be influencing our own.
  • If such evidence is found, it could bring to light many of the universe's mysteries, such as the nature of dark matter.

Physicists puzzled by strange numbers that could explain reality

Eight-dimensional octonions may hold the clues to solve fundamental mysteries.

  • Physicists discover complex numbers called octonions that work in 8 dimensions.
  • The numbers have been found linked to fundamental forces of reality.
  • Understanding octonions can lead to a new model of physics.

Bizarre ‘dark fluid’ with negative mass could dominate the universe – what my research suggests

A new study may change the face of astrophysics.

It's embarrassing, but astrophysicists are the first to admit it. Our best theoretical model can only explain 5% of the universe. The remaining 95% is famously made up almost entirely of invisible, unknown material dubbed dark energy and dark matter. So even though there are a billion trillion stars in the observable universe, they are actually extremely rare.

Are you a Boltzmann Brain? Why nothing in the Universe may be real

A mind-bending paradox questions the nature of reality.

  • Boltzmann Brains are hypothetical disembodied entities with self-awareness.
  • It may be more likely for a Boltzmann Brain to come into existence than the whole Universe.
  • The idea highlights a paradox in thermodynamics.
