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
A civilization of non-human entities could be living here on Earth in facilities hidden deep underground or on the ocean floor, according to a new paper published by three researchers from Harvard and Montana Technological University. The paper explores a wide variety of possibilities concerning both the origin and natureread 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
A recent study has confirmed that a fundamental constant in astrophysics isn’t as constant as it was assumed to be: the universe appears to be expanding at a rate substantially faster than what our calculations say it should be. While this might seem to be a simple problem, it isread more
