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 ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

New tweaks proposed to Einstein’s relativity may do away with them ... "We could no longer use the equations of physics to predict the future from the past and present," he continued.

This general-relativity-based operator leads to a new "entropic action," and to modified Einstein equations. At low energies ...

general relativity, Einstein began work on an alternative form of this cherished idea. His dream was to find a single set of equations that could describe both gravity and electromagnetism.

The relationship between quantum mechanics and classical physics has baffled scientists for decades. In the quantum world, ...

Moreover, at low energies, their modified equations behaved just like Einstein’s general relativity, suggesting that gravity ...

He further added, "We learned from Einstein that Maxwell's equations were relativistic (i.e., invariant under Lorentz transformation) 40 years before relativity. Now we know that they were already ...

All of this is calculated with the equations that underpin general relativity: Einstein's field equations. "The way that the space-time curves is determined by the Einstein field equations ...
