Does the Planck Length Break E=MC^2?
New ReviewEvery good nerd knows that E=mc^2. Every great nerd knows that, really, E^2=m^2c^4+p^2c^2 Want to know what that even means? Sure, I’ll tell you, but today I’d like to invite you to an even higher level of nerdom with extra bits to...

Why Didn’t Antimatter Destroy The Universe? (LHC Breakthrough)
New ReviewAt one-one-thousandth of a second after the Big Bang, the great annihilation event should have wiped out all matter, leaving a universe of only radiation. Why still don't know why any matter survived. Well, a new finding from the LHC...

Are The Fundamental Constants Finely Tuned? (The Naturalness Problem)
New ReviewDid God have any choice in creating the world? So asked Albert Einstein. He was being poetic. What he really meant, was whether the universe could have been any other way. Could it have had different laws of physics, driven by different...

Can Cosmic Voids Solve The Crisis in Cosmology?
New ReviewTwo of the greatest mysteries in cosmology are the nature of dark energy and the apparent conflict in our measurements of the expansion rate of the early versus the modern universe that even dark energy can’t account for. Could both of...

Can the Universe Remember? Exploring Gravitational Memory
New ReviewThere are cosmic events so powerful that they leave permanent marks on the fabric of the universe itself. Imagine two colossal black holes spiraling into each other, yes they send ripples in the fabric of spacetime—gravitational waves...

The Crisis in Physics: Why the Higgs Boson Should Not Exist!
New ReviewAccording to quantum physics, the universe should have collapsed on itself in the instant after the Big Bang due to all particles being 100 million billion times heavier. Recent observations of the universe existing suggest that this may...

Earth Had Rings (and Might Regain Them)
New ReviewPlanet Earth is the jewel of the solar system—the shimmery blue oceans, the verdant green forests, the wispy whimsical cloud formations. Saturn is the only competitor for most gorgeous planet with that giant ring system. Hmm… what if we...

Quantum Energy Teleportation is Real!
New ReviewThe vacuum of space is a chaotic sea of quantum fluctuations. Some have said that this vacuum energy can be harvested to build our future starship engines, or manipulated to build warp drives. It can't. But it is technically possible to...

Does Many Worlds Explain Quantum Probabilities?
New ReviewThe mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem, and it’s arguably the most mysterious outstanding problem in physics. The different interpretations of quantum mechanics...

Interstellar Expansion Without Faster Than Light Travel
New ReviewIn the far future we may have advanced propulsion technologies like matter-antimatter engines and compact fusion drives that allow humans to travel to other stars on timescales shorter than their own lives. But what if those technologies...

Is Gravity Random Not Quantum?
New ReviewThe holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as mythical as the grail of legend? What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? Or...

How To Detect Faster Than Light Travel
New ReviewWarp drives may or may not be possible, but if they are then could a distant alien civilization’s warp fields produce gravitational waves that we could see here on Earth? According to a recent study.. Actually maybe, at least eventually....

What if Humans Are Not Earth's First Civilization? (Silurian Hypothesis)
New ReviewWe’re almost certainly the first technological civilization on Earth. But what if we’re not? We are. Although how sure are we, really? The Silurian hypothesis, which asks whether pre-human industrial civilizations might have existed.

Was the Gravitational Wave Background Finally Discovered?
New ReviewA few weeks ago a large team of gravitational wave astronomers announced something pretty wild. The moderately confident detection of pervasive ripples in the fabric of space time that presumably fills the cosmos, detected by watching...

The Real (Weird) Way We See Numbers
New ReviewWould it surprise you to learn that fish and birds count in pretty much the same way that we do? And that infants can do math? Our animal brains deal with quantities in very specific ways, from quick counts of a few dots to how we...

Memes Go Viral Cuz They're So Sick
When we say a meme goes “viral,” we aren't actually saying it's making people sick. But the math behind a meme’s spread suggests it's actually a pretty spot-on analogy.
