There’s a big difference between the notions of ‘false vacuum’ and ‘true vacuum’ states. Here’s why we don’t want to live in the former.

Magnetic monopoles began as a mere theoretical curiosity. They might hold the key to understanding so much more.
A theoretical physicist returns to Penrose and Hameroff’s theory of “quantum consciousness.”
Perhaps the most remarkable fact about the Universe is simply that it, and everything in it, exists. But what’s the reason why?
A new hypothesis accuses the simple sugar of wrecking energy metabolism.
From the earliest stages of the hot Big Bang (and even before) to our dark energy-dominated present, how and when did the Universe grow up?
An exclusive interview with physicist Lee Smolin reveals how abandoning Einstein’s dream may have been a terrible mistake.
Going to smaller and smaller distance scales reveals more fundamental views of nature, which means if we can understand and describe the smallest scales, we can build our way to […]
Smashing things together at unprecedented energies sounds dangerous. But it’s nothing the Universe hasn’t already seen, and survived.
Without wormholes, warp drive, or some type of new matter, energy, or physics, everyone is limited by the speed of light. Or are they?
Some 13.8 billion years ago, the Universe became hot, dense, and filled with high-energy quanta all at once. Here’s what it was like.
Equations that describe time travel are fully compatible and consistent with relativity — but physics is not mathematics.
Realism in science cannot be completely unmoored from human experience. Otherwise, realism ends up tortured with unreal paradoxes.
Traveling back in time is a staple of science fiction movies. But according to Einstein, it’s a physical possibility that’s truly allowed.
The evidence that the Universe is expanding is overwhelming. But how? By stretching the existing space, or by creating new space itself?
Amplifying the energy within a laser, over and over, won’t get you an infinite amount of energy. There’s a fundamental limit due to physics.
Is the time crystal really an otherworldly revolution, leveraging quantum computing that will change physics forever?
The false assumption the Multiverse relies on is that something which exists requires an explanation.
Is gravity weaker over distances of billions of light-years?
To understand the edges of our universe, we’ll need to explore the edges of our own philosophies.

Quantum theory has weird implications. Trying to explain them just makes things weirder.
The DUNE project will beam tiny neutrinos across vast distances. But the first step involved moving a heavier material: 1 million tons of rock.
There are a few possible solutions to the problem of interstellar travel, but they largely remain within the realm of science fiction.
No. But Buddhism and quantum mechanics have much to teach each other.
The Kalam cosmological argument asserts that everything that exists has a cause, and what caused the Universe? It’s got to be God.
The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?
What do we mean by a black hole’s size? A photon sphere? The minimal stable orbit? The event horizon? The singularity? Which one is right?
Roger Babson wanted a “partial insulator, reflector, or absorber of gravity” — something, anything, that would stop or dampen it.
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 […]
AI was key to making Moderna’s COVID mRNA vaccine. Its role in mRNA therapeutics will rapidly grow in the coming years.
