Physicists are re-exploring the concept of time by thinking about wormholes in space, warp drives and other cosmic constructions, that "absurdly advanced civilizations" might use to travel through time.
Black holes are staples of science fiction and many think astronomers have observed them indirectly. But according to a physicist at the Lawrence Livermore National Laboratory in California, these awesome breaches in space-time do not and indeed cannot exist.
A fireball created in a US particle accelerator has the characteristics of a black hole, a physicist has said.
Scientists searching for waves of gravitational energy that stretch space and time will soon be seeking the public's help in analysing their data.
Michio Kaku argues that new space probes will provide critical new information on parallel universes, cosmology, and wormholes that humanity will need to survive in the long-term.
Scientists have built a device that mimics the magnetic fields surrounding the Earth and other planets. They hope to use the device to understand how the Earth's protective magnetosphere works -- and possibly gain insights into how to make fusion a feasible energy source.
Terahertz Rays, or T-Rays, could be used to detect hidden weapons of mass destruction, according to new research.
The U.S. Air Force has commissioned the Teleportation Physics Study of teleportation of material objects. The study considered teleportation by psychic means, by altering the properties of the spacetime vacuum or spacetime metric, by quantum entanglement, and by transport through extra space dimensions or parallel universes.
Physicists met to discuss plans to link supercomputing centers worldwide into a massive global grid that will help process super collider data.
Astronomers have demonstrated the use of internet technologies and the principle of interferometry to create a giant "virtual telescope" that has a resolution 5 times that of the Hubble Space Telescope.
