To build the metaverse, Facebook needs us to get used to smart glasses.

Last week Facebook released its new $299 “Ray-Ban Stories” glasses. Wearers can use them to record and share images and short videos, listen to music, and take calls. The people who buy these glasses will soon be out in public and private spaces, photographing and recording the rest of us, and using Facebook’s new “View” app to sort and upload that content.

My issue with these glasses is partially what they are, but mostly what they will become, and how that will change our social landscape.

How will we feel going about our lives in public, knowing that at any moment the people around us might be wearing stealth surveillance technology? People have recorded others in public for decades, but it’s gotten more difficult for the average person to detect, and Facebook’s new glasses will make it harder still since they resemble and carry the Ray-Ban brand.

That brand’s trusted legacy of “cool” could make Facebook’s glasses appeal to many more people than Snap Spectacles and other camera glasses. (Facebook also has roughly 2 billion more users than Snapchat.) And Facebook can take advantage of the global supply chain and retail outlet infrastructure of Luxottica, Ray-Ban’s parent company. This means the product won’t have to roll out slowly—even worldwide.

Quantum technologies are already revolutionizing life on Earth. But they also have the potential to change the way we operate in space. With the U.S., China, and Europe all investing heavily in this area, these changes are likely to be with us sooner rather than later.

So how will space-based quantum technologies make a difference?

Now, we get an overview thanks to the work of Rainer Kaltenbaek at the Institute for Quantum Optics and Quantum Information, in Austria, and colleagues throughout Europe, who have mapped out the future in this area and set out the advances that space-based quantum technologies will make possible.

While quantum computing and quantum communication grab most of the headlines, Kaltenbaek and colleagues point out that other quantum technologies are set to have equally impressive impacts. Take, for example, atom interferometry with quantum sensors.

These devices can measure with unprecedented accuracy any change in motion of a satellite in orbit as it is buffeted by tiny variations in the Earth’s gravitational field. These changes are caused by factors such as the movement of cooler, higher-density water flows in the deep ocean, flooding, the movement of the continents, and ice flows.
