The elusive phenomenon known as dark matter may not actually exist, according to a University of Alabama astrophysicist, due to the possibility that gravity—an effect caused by the curving of the fabric of spacetime—may exist on its own in the absence of mass, despite the long-held assumption that gravity isread more
An international team of physicists has found a way for a hypothetical warp drive to operate using ordinary physics, by eliminating the drive’s need for the seemingly-impossible exotic energies that would be required to bend the very fabric of space and time around the traveler. Although the universe imposes aread more
Two astrophysicists are proposing that the identity of the invisible source of the majority of the gravitational glue that holds galaxies together—otherwise known as dark matter—may be a hypothetical particle that travels faster than the speed of light that was first introduced over half a century ago. These superluminal particles, betterread more
The particles that make up the Universe around us are out of balance, and physicists are searching for a cause. Following the Big Bang, there should have been an equal number of particles that mirror one-another. I.e. there should be just as much antimatter in the universe as there isread more
