A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein’s classical concept of spacetime is announced today in two papers published simultaneously…
What Is the Theory of Relativity? Relativity is two related theories: special relativity, which explains the relationship between space, time, mass, and energy; and general…
Research teams from Leibniz University Hannover and University of Bremen confirm another equivalence principle. Scientists used a half-century of lunar laser ranging data to confirm…
New techniques can answer questions that were previously inaccessible experimentally — including questions about the relationship between quantum mechanics and relativity. Scientists at TU Wien…
How would our world be perceived by observers moving faster than light in a vacuum? According to theorists from Warsaw and Oxford universities, such a…
The theory of relativity was developed by Albert Einstein in the early 1900s due to the inability of classical physics to explain certain observations. It…
How can Einstein’s theory of gravity be unified with quantum mechanics? It is a challenge that could give us deep insights into phenomena such as…
A new Italian experiment indicates that neutrinos stay within the speed of light. The findings were posted on arXiv.org as a preprint, and contradict rival…
Back in September, the revolutionary claim that the OPERA collaboration had measured neutrinos traveling at faster-than-light speed is now in doubt, as two possible sources…
