The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer’s suggestive simulation.

When you combine the Uncertainty Principle with Einstein’s famous equation, you get a mind-blowing result: Particles can come from nothing.
The matter that creates black holes won’t be what comes out when they evaporate. Will the black hole information paradox ever be solved?
The quantum world — and its inherent uncertainty — defies our ability to describe it in words.
There could be variables beyond the ones we’ve identified and know how to measure. But they can’t get rid of quantum weirdness.
“Once quantum mechanics is applied to the entire cosmos, it uncovers a three-thousand-year-old idea.”
When it comes to predicting the energy of empty space, the two leading theories disagree by a factor of 100 googol quintillion.
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
It’s not about particle-antiparticle pairs falling into or escaping from a black hole. A deeper explanation alters our view of reality.
Physicists just can’t leave an incomplete theory alone; they try to repair it. When nature is kind, it can lead to a major breakthrough.
They say that nobody understands quantum mechanics. But thanks to these three pioneers in quantum entanglement, perhaps we do.
There is no such thing as a void in the Universe.
We are not yet at the point where quantum communications can be deployed to secure the internet, but we might not be far off.
It isn’t just identical particles that can be entangled, but even those with fundamentally different properties interfere with each other.
In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?
Gravity defies quantum mechanics. What does that mean for a theory of everything?

Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.
Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would “ER = EPR” mean for our Universe?
Einstein always loses in the quantum realm.
Maybe the brain isn’t “classical” after all.
When black holes disappear, what happens to the stuff that fell in? Physicist Brian Cox explains.

Quantum superposition challenges our notions of what is real.
What would become the Big Bang model started from a crucial idea: that the young Universe was denser and hotter.
Sabine Hossenfelder talks about Albert Einstein, dead grandmothers, the physics of aging, and more in this full interview with Big Think.

The quantum world is one in which rules that are completely foreign to our everyday experience dictate bizarre behavior.
If nature were perfectly deterministic, atoms would almost instantly all collapse. Here’s how Heisenberg uncertainty saves the atom.
The double-slit experiment, hundreds of years after it was first performed, still holds the key mystery at the heart of quantum physics.
Perhaps wormholes will no longer be relegated to the realm of science fiction.
Though he renounced philosophy, Stephen Hawking’s final theory of the universe redraws the basic foundations of cosmology.
By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.
