The mysterious case of dark energy and the universe’s fate.
Imagine the universe as a vast, ever-expanding balloon.
The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much.
There is a theory dubbed “quantum consciousness,” which stipulates that brain functions and consciousness are derived from quantum effects like the collapse of the quantum wavefunction.
This is a strange part of quantum physics, where particles go from a state of simultaneous properties to a more “normal” state where they have one defined characteristic. It has notably been popularized by the concept of Schrödinger’s cat.

Cosmic surveys suggest the force pulling the universe apart might not be constant after all.
Imagine sitting in the center of a firework that has just exploded. After the first flash of light and heat, sparks fly off in all directions, with some streaming together into fiery filaments and others fading quickly into cold, ashy oblivion. After a moment more, the smoke is all that remains—the echo, if you will, of the firework’s big bang.

Nuclear power is one of the most promising ways to create a clean, cheap, and consistent flow of electricity. Unfortunately, it also produces radioactive waste, which can stick around for…a very long time. However, that waste issue might just be changing thanks to a process called transmutation. A Swiss company just got approval for the first accelerator-driven nuclear reactor that can do transmutation. How does this work? Let’s take a look.

Every clear night for the last three weeks, Bob Stephens has pointed his home telescope at the same two stars in hopes of witnessing one of the most violent events in the universe—a nova explosion a hundred thousand times brighter than the sun.
The eruption, which scientists say could happen any day now, has excited the interest of major observatories worldwide, and it promises to advance our understanding of turbulent binary star systems.
Yet for all the high-tech observational power that NASA and other scientific institutions can muster, astrophysicists are relying on countless amateur astronomers like Stephens to spot the explosion first.

Consciousness creep.
Our machines could become self-aware without our knowing it.
Our machines could become self-aware without our knowing it. We need a better way to define and test for consciousness.
