Albert Einstein is rightfully considered one of the most impactful physicists of all times. He created his various theories of relativity, which govern the behavior of matter moving at tremendous speeds and reimagined the force of gravity as the bending of space and time. He also wrote prodigiously on the idiosyncrasies of quantum mechanics, rejecting it as being fundamentally incorrect, yet exploring the implications of the theory.

While Einstein’s reputation as a genius is secure, a little extra validation never hurts, especially when it revolves around one of Einstein’s most exotic predictions: wormholes, or tunnels through space.

This week, a consortium of researchers from Caltech, Google, Fermilab, MIT, and Harvard used a device called the Sycamore quantum processor to generate and control what is equivalent to a wormhole. (The Sycamore is a quantum computer developed by Google.) How does this work? It comes down to intricate interconnections between two of Einstein’s ideas.

Circular Services is poised to expand the circularity ecosystem

Recycling may be the lowest-priority action in the circular economy. But there’s no denying that it is a necessary component in the shift away from the current linear economy.

With its recent launch of Circular Services, a recycling and reuse company, it’s clear that Closed Loop Partners (CLP) agrees. The investment firm majority-owns and manages Circular Services. And through its Global Transition Fund (BGTF), Brookfield Renewable, it has made a $700 million investment in recycling infrastructure, with an initial $200 million to establish Circular Services and $500 million earmarked for growing the ecosystem.

"We cannot create a net zero economy without significantly scaling the infrastructure required for a circular economy," Natalie Adomait, managing partner and chief investment officer of BGTF, said in a statement.

Blockchain gaming under the microscope part 2: the bubble

This four-part series dives deep into the recently published 2022 Blockchain Gaming Report to distill the key insights for readers. The first part looked at the potential for mass adoption of blockchain gaming, in which players use blockchain technology to earn assets with real-world value. This second part looks at the speculation bubble in play-to-earn games, and asks whether it has burst.

With the exception of STEPN, a game released in March that rewards users for physical movement, prominent games like Axie Infinity, Pegaxy and Crabada are down more than 80% in value from their all-time highs. This is part of an unravelling of play-to-earn games’ token valuations since the start of 2022. Besides the dwindling market capitalization, user numbers are decreasing as well. Axie Infinity's daily active users (DAUs) peaked in November 2021, before undergoing a steep fall. STEPN has also seen a meteoric rise and an equally steep fall in user interest.

🌙 NASA - Best Photo from Last Week
Orion’s Moon Crater Close-up

On the sixth day of the Artemis I mission, Nov. 21, 2022, the Orion spacecraft’s optical navigation camera captured black-and-white images of craters on the Moon below. This photo and others captured are the closest photos of the Moon from a human-rated vessel since Apollo. The optical navigation camera takes black-and-white imagery of the Earth and the Moon at different phases and distances; this technology demonstration will help prove its effectiveness for future missions with crew.
