Entanglement—linking distant particles or groups of particles so that one cannot be described without the other—is at the core of the quantum revolution changing the face of modern technology.
While entanglement has been demonstrated in very small particles, new research from the lab of University of Chicago Pritzker School of Molecular Engineering (UChicago PME) Prof. Andrew Cleland is thinking big, demonstrating high-fidelity entanglement between two acoustic wave resonators.
Astronomers have found a black hole in the early Universe that has a jet pointed at Earth, and which could help solve how the cosmic ‘dark ages’ came to an end.
A team led by Yale University found the ‘quasar’, which is brightening and dimming intensely.
Despite strong interest in using artificial intelligence to make research faster, easier and more accessible, researchers say they need more support to navigate its possibilities.
Can you make something invisible? Neil deGrasse Tyson and comedian Negin Farsad discover the science behind invisibility with professor of physics and optical science, Greg Gbur. What would real-life invisibility look like?
Can you be invisible in other parts of the magnetic spectrum? We discuss transparency versus invisibility and how metamaterials help us interact with different wavelengths. What does light have to do in order to make something invisible? We break down invisibility cloaks and other invisibility devices from fiction.
Could you make yourself invisible to all parts of the electromagnetic spectrum? We explore the main challenges in achieving invisibility and the difference between passive and active invisibility. How useful of a power would it be?
We discuss the interaction between waves and matter. What makes some waves reflect off matter and others pass through? Learn about x rays and how they work, plus, an at-home invisibility trick using prisms. Finally, could you make someone invisible to time?

Theoretical warp technology exists in what we know as the Alcubierre drive. In this video, I will explain how this theoretical warp technology works and the problems that we face in developing it. You will also get to see some mathematically accurate simulations of a spaceship using an Alcubierre drive, travelling at 1,000 light years per second!
In Star Trek, Star Wars, Dune and many other sci-fi stories where space travel exists, the common question that viewers have is: how do these humans achieve faster than light travel? The term “Warp travel” and “Warp speed” were originally coined by the Star Trek franchise. It is also known by other franchises as “Jump” or “folding of space” and the engines that cause this to happen are the “warp drive” or the “hyper drive” Ultimately, the idea of bending space is embedded within all of these sci-fi stories, and with good reason.
It is impossible to travel faster than light within space. But space itself can bend, fold, move, expand at any speed or rate.
The alcubierre drive uses the principals in general relativity to bend space around a spaceship in such a way, that the space itself begins to move, carrying along anything within it. So although the spaceship is not technically moving within the space it occupies, the space around the spaceship allows motion to occur.
