Dark Energy Hidden Behind Phantom Fields

FECYT - Spanish Foundation for Science and Technology Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy. Now researchers from Barcelona and Athens suggest that both possibilities are only a mirage in the observations and it is the quantum vacuum which could be behind this energy that moves our universe. Cosmologists believe that some three quarters of...

Dark energy makes up about 70 percent of the current content of the Universe and thus holds the ultimate fate of our Universe. Several possible scenarios are possible depending on the properties of dark energy; one is that the Universe will end in a so-called big rip. This interesting topic was recently explored by five researchers from the University of Science and Technology of China, the Institute of Theoretical Physics at the Chinese Academy of Sciences, Northeastern University, and...

INR -- When physicists first suggested that our universe could end in a big rip -- a violent death in which all matter would be torn apart -- they struggled to explain one thing: how could anything shred black holes? Now it seems that the energy driving the big rip would dissolve black holes like aspirins in a glass of water. Whether the big rip happens or not depends on the nature of the dark energy that is believed to be pulling the universe apart. One form this energy could take is...

Accelerating universe -- In the late 1990s, observations of type I supernova produced the unexpected result that the expansion of the universe appears to be accelerating. These observations appear more firm as new data has appeared. This means that the speed with which a distant galaxy recedes from us increases over time. If this trend continues, eventually we won't be able to see any other galaxies any more. This new theory of the end of the Universe has been called the Big Rip....

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
