Realizing that matter and energy are quantized is important, but quantum particles aren’t the full story; quantum fields are needed, too.

When cosmic inflation came to an end, the hot Big Bang ensued as a result. If our cosmic vacuum state decays, could it all happen again?

The quantum world — and its inherent uncertainty — defies our ability to describe it in words.

“Once quantum mechanics is applied to the entire cosmos, it uncovers a three-thousand-year-old idea.”

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

There could be variables beyond the ones we’ve identified and know how to measure. But they can’t get rid of quantum weirdness.

Sabine Hossenfelder talks about Albert Einstein, dead grandmothers, the physics of aging, and more in this full interview with Big Think.

By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.

What would become the Big Bang model started from a crucial idea: that the young Universe was denser and hotter.

Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would “ER = EPR” mean for our Universe?

It isn’t just identical particles that can be entangled, but even those with fundamentally different properties interfere with each other.

Isaac Newton and Albert Einstein are locked in an eternal battle over the nature of gravity. Whose side are you on?

It’s 2024, and we still only know of the fundamental particles of the Standard Model: nothing more. But these 8 unanswered questions remain.

Scientists can make substantial progress without fully understanding exactly what they’re doing.

The double-slit experiment, hundreds of years after it was first performed, still holds the key mystery at the heart of quantum physics.

They say that nobody understands quantum mechanics. But thanks to these three pioneers in quantum entanglement, perhaps we do.

We are not yet at the point where quantum communications can be deployed to secure the internet, but we might not be far off. 

Quantum superposition challenges our notions of what is real.

Though he renounced philosophy, Stephen Hawking’s final theory of the universe redraws the basic foundations of cosmology.

Maybe the brain isn’t “classical” after all.

When one path is blocked, a new one must be paved. How Einstein, Heisenberg and Gödel used constraints to make life-changing discoveries:

Plants at room temperature show properties we had only seen near absolute zero.

You will need determination, humility, and courage if you are to master anything.

The quantum world is one in which rules that are completely foreign to our everyday experience dictate bizarre behavior.

Is science close to explaining everything about our Universe? Physicist Sabine Hossenfelder reacts.

Einstein always loses in the quantum realm.

Recent measurements of subatomic particles don’t match predictions stemming from the Standard Model.

Glueballs are an unusual, unconfirmed Standard Model prediction, suggesting bound states of gluons alone exist. We just found our first one.

Humanity is a type 0 civilization. Here’s what types 1, 2, and 3 look like, according to physicist Michio Kaku.

Perhaps wormholes will no longer be relegated to the realm of science fiction.
