Quantum Entanglement
We are not yet at the point where quantum communications can be deployed to secure the internet, but we might not be far off.
Holograms preserve all of an object's 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?
Einstein always loses in the quantum realm.
Uncertainty is inherent to our Universe.
They say that nobody understands quantum mechanics. But thanks to these three pioneers in quantum entanglement, perhaps we do.
Quantum mechanics forces us to toss out the old, reliable ways in which we make sense of our everyday reality.
Quantum communication offers a surer path to sending an interstellar message, as well as receiving one. But can we do it?

Our world would be impossible without quantum mechanics — but we still don’t have a narrative of how it works.

How efficiently could quantum engines operate?
Hidden variables aren’t ruled out, but they can’t get rid of quantum weirdness. Ever since the discovery of the bizarre behavior of quantum systems, we’ve been forced to reckon with […]
If you can’t surpass it in a vacuum, try doing so in a medium instead. In our Universe, there are a few rules that everything must obey. Energy, momentum, and angular […]
We still don’t know how the information encoded onto it gets out. No matter what you do in the Universe, its overall entropy always increases. Even when we put things in […]
It’s perhaps the most famous thought experiment in all of physics, but is full of popular myths and misconceptions. One of the most bizarre ideas about the quantum Universe is […]
Even physicists sometimes fall for these. For centuries, the laws of physics seemed completely deterministic. If you knew where every particle was, how fast it was moving, and what the forces […]
It’s a pipe dream that violates the laws of physics, and not even quantum mechanics can give us a way out. One of the most fundamental rules of physics, undisputed since […]
A single thought experiment reveals a paradox. Could quantum gravity be the solution? Sometimes, if you want to understand how nature truly works, you need to break things down to […]
On September 27, 1972, scientists performed the first test of Bell’s inequality. God does play dice with the Universe, after all. One of the most puzzling and counterintuitive aspects of quantum […]
The deep dive into the mirror Universe, and the ethics of how we deal with purity and diversity, is just getting started. Life in the mirror Universe isn’t easy for anyone. […]
With quantum teleportation now occurring from Earth to satellites, how long is it before we can teleport a human being? “There would be no Star Trek unless there were transporter malfunctions.” –LeVar […]
Gravity is the oldest fundamental force ever discovered. Might it not be fundamental after all? “The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic […]
