New quantum gravity theory brings the world closer to ‘Theory of Everything’

Source: MSN Story by Tejasri Gururaj A unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other fundamental forces (electromagnetic, weak, and strong) described using quantum field theory (QFT). The fundamental discrepancy between the unification lies in how the two theories are described. The gravitational field—described by Einstein’s theory…

New research findings challenge Einstein’s landmark theory of relativity

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales. To explain this cosmic acceleration, scientists have developed a variety of ideas. Some turn to the cosmological constant—a constant energy density filling all of space. Others explore dark energy as something more dynamic. Still, others question …
