This week, Quanta featured a three-part series on spacetime. Part 1 is by K.C. Cole: Wormholes Untangle a Black Hole Paradox. A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information. I wrote Part 2, on tensor networks and entanglement. How Quantum Pairs Stitch Space-Time: New tools may reveal how quantum information builds the structure of space. Finally, Part 3 featured an interactive presentation that illustrates the relationship between entanglement, tensor networks and space-time.

What Does Scientific Consensus Mean? Should we get vaccinated? Fluoridate our water? Fight global warming? Believe in evolution? The Big Bang? Dark matter?
“If you want to construct an accurate picture of what governs the Universe, you need to build on all that we’ve learned up to this point. And when we say “scientific consensus,” that’s what we’re talking about: things we’ve already learned, and the solid foundation for where we go from here. You might have grown up believing that doing something yourself is the only way to ensure it gets done correctly. But when it comes to science, not only is that not the case at all, but a scientific consensus isn’t the conclusion, but rather the starting point.”
