1 day ago · In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein's 1905 treatment, the theory is presented as being based on just two postulates:
5 days ago · This ability to observe the effects of general relativity at the microscopic scale can significantly bridge the gap between the microscopic quantum realm and the large-scale phenomena described by general relativity. Navigating Space and Quantum Advances . More precise atomic clocks also enable more accurate navigation and exploration in space.
21 hours ago · As predicted by the theory of general relativity, the passage of gravitational waves can leave a measurable change in the relative positions of objects. ... Solar Activity and Space Weather Update ...
5 days ago · General relativity is Einstein’s theory that describes how gravity is caused by the warping of space and time. One of the key predictions of general relativity is that time itself is affected by ...
5 days ago · Generalized Siklos space-times. Motivated by supersymmetry methods in general relativity, we study four-dimensional Lorentzian space-times with a complex Dirac spinor field satisfying a Killing-spinor-like equation where the Killing constant is promoted to a complex function. We call the resulting geometry a generalized Siklos space-time.
4 days ago · Explore the June 2023 issue featuring the following: ‘Homegrown’ Engineer Supports NASA Missions, Relativity Space Hits Key Testing Milestones at Stennis, Partners for Stennis Shines Light on Center, Honor Juneteenth and its Historic Legacy, Pride Month Highlights Stonewall Leaders and much more!
2 days ago · Supermassive black hole (BH) mergers with spin-flips accelerate energetic particles through their relativistic precessing jets, producing high-energy neutrinos and finally gravitational waves (GWs). In star formation, massive stars form in pairs, triplets, and quadruplets, allowing second-generation ...
