Time has a fundamentally different character in quantum mechanics and when in general relativity. In quantum theory, events develop in a fixed order while in general relativity temporal order is affected by the distribution of matter.

Now, a team of international scientists has discovered a new kind of quantum time order. Through this study, scientists sought to determine: what happens when an object massive enough to influence the flow of time is placed in a quantum state?

The disclosure emerged from a test the group intended to bring together elements of the two significant physics theories developed in the past century.

Samsung is looking forward to what life might be like in the year 2069. The new report, called Samsung KX50: The Future in Focus, draws on the opinions of six of Britain’s leading academics and futurists to look at a range of new technologies that will affect people’s everyday lives.

Trying to predict the future is a dodgy business that has a notoriously low success rate. If the world of 2019 was anything like past predictions, we should have flying cars, personal jet packs, robot butlers, 100 percent atomic power producing limitless energy, little bottles containing nanobots that can grow cars on the front lawn, colonies on the Moon and Mars – and all in a society that hasn’t changed much since 1960, except it’s a bit nicer.

Could physics help people with epilepsy? That’s the question tackled by Louis Nemzer, a physicist at Nova Southeastern University, in the September 2019 issue of Physics World magazine, which is out now in print and digital formats.

He thinks that machine learning and real-time monitoring of the brain could give people with epilepsy live information about how much at risk they are of an imminent seizure – and is even developing a smartphone app to help them in daily life.

Elsewhere in the issue, Peter Martin and Tom Scott from the University of Bristol describe how they’ve used drones to map radiation levels at the Chernobyl plant, which you can also read on this website from 2 September, while Kate Brown from the Massachusetts Institute of Technology examines the health impact of Chernobyl fall-out.

A team of researchers has just demonstrated quantum enhancement in an actual X-ray machine, achieving the desirable goal of eliminating background noise for precision detection.

The relationships between photon pairs on quantum scales can be exploited to create sharper, higher-resolution images than classical optics. This emerging field is called quantum imaging, and it has some really impressive potential — particularly since, using optical light, it can be used to show objects that can’t usually be seen, like bones and organs.

Quantum correlation describes a number of different relationships between photon pairs. Entanglement is one of these, and is applied in optical quantum imaging.

In its most hubristic and unquestioning form, bolstered by unapologetic and brash advanced capitalist logics, transhumanism poses myriad threats: from automation unemployment to the end of democracy, to the risk that humans will branch into different species, making questions of inequality infinitely more urgent. Even if immortality arrives it will be accompanied by crimes, wars, and accidents—as Cantona states.


Technology is on the brink of making it possible to live forever—but should we?
