Researchers use the S-matrix bootstrap to examine whether string theory is the only consistent theory of quantum gravity

The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few decades, some physicists have ...

Not all theories can explain the black hole M87*

As first pointed out by the German astronomer Karl Schwarzschild, black holes bend space-time to an extreme degree due to their extraordinary concentration of mass, and heat up the matter in their vicinity so that it begins ...
