As anyone who's ever seen a science fiction movie knows, whipping up a black hole in a laboratory doesn't seem like such a good idea. But that didn't stop researchers in England who wanted to see if they could create something in the lab that would serve as a black hole analog and give them greater insights into the way spacetime curves near the galactic gravity gobblers.So researchers from the University of Nottingham (UN), King's College London, and Newcastle University turned to vortices in fluids, which can, in some…

The Radcliffe Wave next to our sun (yellow dot), inside a cartoon model of the Milky Way. Blue dots are clusters of baby stars. The white line is a theoretical model by Ralf Konietzka and collaborators that explains the current shape and motion of the wave. The magenta and green lines show how the wave will move in the future.

This artist’s illustration shows a cross-section of the supermassive black hole and surrounding material in the center of our galaxy. The black sphere in the center represents the event horizon of the black hole, the point of no return from which nothing, not even light, can escape. Looking at the spinning black hole from the side, as depicted in this illustration, the surrounding spacetime is shaped like an American football. The yellow-orange material to either side represents gas swirling around the black hole. This…

Under The Hood Of The Generative AI For Video By OpenAIHow can AI transform a static image into a dynamic, realistic video? OpenAI’s Sora introduces an answer through the innovative use of spacetime patches.In the rapidly evolving landscape of generative models, OpenAI’s Sora stands out as a significant milestone, promising to reshape our understanding and capabilities in video generation. We unpack the technology behind Sora and its potential to inspire a new generation of models in image, video, and 3D content…

A supermassive monster lurks at the center of our galaxy, and astronomers have now discovered that it’s spinning so fast it’s warping the very fabric of spacetime into a football shape.According to Einstein’s general theory of relativity, mass bends spacetime, a four-dimensional “fabric” that pervades the universe, and the effect is what we experience as gravity. It happens with any amount of mass – you yourself are bending spacetime right now – but it’s barely noticeable until you’re dealing with extremely massive…

The supermassive black hole at the center of the Milky Way may look more like a football than a circle, new research suggests. The new study, which appears in Monthly Notices of the Royal Astronomical Society, suggests that the Milky Way’s black hole is spinning so fast that it’s actually warping space-time.“Our work may help settle the question of how fast our galaxy’s supermassive black hole is spinning,” said Ruth Daly, lead author of the new study. “Our results indicate that Sgr A* is spinning very rapidly,…

The European Space Agency (ESA) has approved the Laser Interferometer Space Antenna (LISA) mission, the first scientific endeavour to detect and study cosmic ripples from space.  The launch of LISA is planned for 2035, on an Ariane 6 rocket. The project is expected to be the most expensive and complex the agency has ever undertaken.  Cosmic ripples, also known as gravitational waves, are created during some of the most dramatic events in the Universe, such as when black holes collide.  By…

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and importantly, outlines a way to test it experimentally.Over the past century or so, quantum physics has done an excellent job of describing the micro-scale world of particles and atoms. It encompasses three of the four fundamental forces of the universe – electromagnetism and the strong and weak nuclear forces. But despite…
