Researchers have shown how singularities – which are normally only found at the centre of black holes and hidden from view – could exist in highly curved three-dimensional space.

(Phys.org)—Scientists have proposed an experiment that could measure the value of Newton's gravitational constant, G, from deep space instead of an Earth-based laboratory. The researchers predict that the deep space experiment ...
In quantum gravity, classical physics and quantum mechanics are at odds: scientists are still uncertain how to reconcile the quantum "granularity" of space-time at the Planck scale with the theory of special relativity. In ...

(Phys.org)—Although in theory it may seem possible to divide time up into infinitely tiny intervals, the smallest physically meaningful interval of time is widely considered to be the Planck time, which is approximately ...
When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theorists from the faculty of physics, University of Warsaw have shown that in models of the universe using any of ...

Gravity ties our bodies to planet Earth but it does not define the limits of the soaring human mind. In November 1915 – exactly one century ago – this was proven to be true when Albert Einstein, in a series of lectures ...
