Quantum entanglement may remain spooky, but it has a very practical side.
IceCube scientists have detected high-energy tau neutrinos from deep space, suggesting that neutrino transformations occur not only in lab experiments but also over cosmic distances.
Holograms preserve all of an object’s 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?
Cosmic inflation is the state that preceded and set up the hot Big Bang. Here’s what the Universe was like during that time period.
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
The Universe didn’t begin with a bang, but with an inflationary “whoosh” that came before. Here are the biggest questions that still remain.
We have two descriptions of the Universe that work perfectly well: General Relativity and quantum physics. Too bad they don’t work together.
The term “zero-point energy” has at least two meanings, one that is innocuous and one that is a great deal sexier (and scammier).
Yes, “the laws of physics break down” at singularities. But something really weird must have happened for black holes to not possess them.
For nearly a century, physicists have argued over how to interpret quantum physics. But reality exists independent of any interpretation.
The “first cause” problem may forever remain unsolved, as it doesn’t fit with the way we do science.
Like Dua Lipa, he had to create new rules.
For decades, theorists have been cooking up “theories of everything” to explain our Universe. Are all of them completely off-track?
If it weren’t for the intricate rules of quantum physics, we wouldn’t have formed neutral atoms “only” ~380,000 years after the Big Bang.
Quantum communication offers a surer path to sending an interstellar message, as well as receiving one. But can we do it?
Empty space itself, the quantum vacuum, could be in either a true, stable state or a false, unstable state. Our fate depends on the answer.
U.S. particle physicists recently recommended a list of major research projects that they hope will receive federal funding.
Even with the quantum rules governing the Universe, there are limits to what matter can withstand. Beyond that, black holes are unavoidable.
Despite the Sun’s high core temperatures, particles can’t quite overcome their mutual electric repulsion. Good thing for quantum physics!
That scary swirling void from which nothing can escape is our perfect universal translation tool.
In the earliest stages of the hot Big Bang, equal amounts of matter and antimatter should have existed. Why aren’t they equal today?
Quantum mechanics forces us to toss out the old, reliable ways in which we make sense of our everyday reality.
In our common experience, you can’t get something for nothing. In the quantum realm, something really can emerge from nothing.
We think of physical reality as what objectively exists, independent of any observer. But relativity and quantum physics say otherwise.
By focusing on the role of human experience, we may uncover new insights on the fundamental structure of reality.
In 1974, Hawking showed that black holes aren’t stable, but emit radiation and decay. Nearly 50 years later, it isn’t just for black holes.
The multiverse is an idea that has gained a lot of traction in popular culture. But what does science have to say about it?
The question of why the Universe is the way it is is an ancient one, and none of the answers we have come up with are satisfying.
The familiar terrain of solids, liquids, and gases gives way to the exotic realms of plasmas and degenerate matter.
