Could We Be Wrong About Gravitational Waves?

“In 2010, Erik Verlinde surprised the world with a completely new theory of gravity. According to Verlinde, gravity is not a fundamental force of nature, but an emergent phenomenon. In the same way that temperature arises from the movement of microscopic particles, gravity emerges from the changes of fundamental bits of information, stored in the very structure of spacetime.”

Could the Future be Influencing the Past?

Original article via Science Alert

One of the weirder aspects of quantum mechanics could be explained by an equally weird idea – that causation can run backwards in time as well as forwards.

What Einstein called “spooky” action at a distance could theoretically be evidence of retrocausality, which is the particle equivalent of you getting a stomach ache today thanks to tomorrow’s bad lunch.

Time Crystals: A New state of Matter

Sorry it’s been quiet here for a while. Exam season slows us down a little.

Original article via Science Alert

It’s official: time crystals are a new state of matter, and now we can create them – ScienceAlert:

Earlier this year, physicists had put together a blueprint for how to make and measure time crystals – a bizarre state of matter with an atomic structure that repeats not just in space, but in time, allowing them to maintain constant oscillation without energy.

Two separate research teams managed to create what looked an awful lot like time crystals back in January, and now both experiments have successfully passed peer-review for the first time, putting the ‘impossible’ phenomenon squarely in the realm of reality. More…
