But they are also forbidden by so-called energy conditions, a handful of restrictions that the renowned physicists Roger Penrose and Stephen Hawking slapped on top of general relativity to stop the ...

In 1965, British mathematician Roger Penrose proposed the cosmic censorship conjecture, a concept that suggests that singularities — regions where gravity is so strong that the fabric of spacetime ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

One of the most important paradoxes in physics is Schrödinger's Cat. At the microscopic level, light and particles behave according to quantum mechanics. This allows them to be in two places at once ...
