The Einstein equations remain the cornerstone of general relativity, underpinning our understanding of how matter and energy influence spacetime curvature. Recent investigations have not only ...
Albert Einstein, in 1905, presented the revolutionary idea of light quanta of energy which equals ħw, where ħ is reduced Planck's constant. There is plenty of experimental evidence on magnetic flux ...
Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...
Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...
In November 1915, in a lecture before the Prussian Academy of Sciences, Albert Einstein described an idea that upended humanity’s view of the universe. Rather than accepting the geometry of space and ...
Annals of Mathematics, Second Series, Vol. 161, No. 3 (May, 2005), pp. 1143-1193 (51 pages) This is the first in a series of papers in which we initiate the study of very rough solutions to the ...
A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...
A homogeneous linear difference equation with constant coefficients over a locally compact abelian group $G$ is an equation of the form $\sum^n_{j=1} c_jf (t_jx) = 0 ...
