Black holes don’t just swallow matter and light; they also twist and warp the fabric of space-time around them. This is what gives rise to phenomena like gravitational lensing, where the path of light from a distant object is bent when it passes near a black hole, causing the object to...
We show how some physics behind black holes, simple clocks, simple computers, and the holographic principle is related to Planck-scale physics. We also discuss a formulation of the Dirac equation as a difference equation on a discrete Planck-scale spacetime lattice, and a possible interplay ...
Recent simulations of two black holes colliding at close to the speed of light have shed light on the enigmatic physics behind what has been called by one astrophysicist as “one of the most violent events you can imagine in the universe.” “It’s a bit of a crazy thing ...

Hi, I wanted to explain quantum tunnelling to people with no scientific background - I've come up with the following analogy, but I'm only a physics undergrad and I'm not sure if it's a good enough analogy. I can do the maths behind tunnelling but it's just the concept I'm tryin...
“And then one day you find ten years have got behind you; no one told you when to run, you missed the starting gun.”– Roger Waters, “Time” Inertia is a stabilizing force that keeps people in their comfort zone and businesses on a straight and narrow path. It can[…]Read On ...
Perturbative hard scattering processes at energies well above the Planck scale are cloaked behind a horizon, thus limiting the ability to probe short distances. The high energy black hole cross section grows with energy at a rate determined by the dimensionality and geometry of the extra dimensions...
The merger of a binary black hole gives birth to a highly distorted final black hole. The gravitational radiation emitted as this black hole relaxes presents us with the unique opportunity to probe extreme gravity and its connection with the dynamics of
Simulation of material orbiting close to a black hole (ESO/Gravity Consortium/L. Calçada) Full disclosure:I wrote the press release for the University of Waterloo, whose researcher, Avery Broderick, developed the theory behind the accretion disk hotspots that have now been observed immediately sur...
