The NEW SCIENCE of Moon Formation
Einstein once asked whether “the moon exists only when I look at it?". It was rhetorical objection to the idea that measurement in quantum...

What If The Universe Is Math?
In his essay “The Unreasonable Effectiveness of Mathematics”, the physicist Eugine Wigner said that “the enormous usefulness of...

What If Alien Life Were Silicon-Based?
Life as we know it is carbon-based, but does it have to be this way? There’s another element on the periodic table that shares some of the key...

How Earth REALLY Moves Through the Galaxy
Perhaps you’ve seen videos of how the planets of the solar system move through the universe in this cool helix. Not only are these misleading,...

How Does The Nucleus Hold Together?
Two protons next to each other in an atomic nucleus are repelling each other electromagnetically with enough force to lift a medium-sized labradoodle...

What If Space And Time Are NOT Real?
Physics progresses by breaking our intuitions, but we’re now at a point where further progress may require us to do away with the most...

What’s Your Brain’s Role in Creating Space & Time?
Physics is the business of figuring out the structure of the world. So are our brains. But sometimes physics comes to conclusions that are in direct...

What If Black Holes ARE Dark Energy?
We tend to imagine there are connectings between things that we don’t understand. Quantum mechanics and consciousness, aliens and pyramids,...

How Much Of The Universe Can Humanity Ever See?
There’s an absolute limit to our access to the universe beyond our own galaxy. There’s a limit to what we can ever hope to explore or...

How Far Beyond Earth Could Humanity Spread?
We humans have always been explorers. The great civilizations that have arisen across the world are owed to our restless ancestors. These days,...

NEW DISCOVERY About Supermassive Black Holes Explained!
Astrophysicists have discovered a black hole that for millions of years has been blasting vast particle beams in opposite directions across the sky....

Understanding One of Physics' Most Challenging Topics!
If I roll a pair of dice and you get to bet on one number, what do you choose? The smart choice is 7 because there are more ways for 2 dice to come...

Finding Alien Spacecraft with Gravitational Waves
Whenever we open a new window on the universe, we discover things that no one expected. Our newfound ability to measure ripples in the fabric of...

Is 'Perpetual Motion' Possible with Superfluids?
The weird rules of quantum mechanics lead to all sorts of bizarre phenomena on tiny scales— particles teleporting through walls or being in...

Can We Move PLANET EARTH Across the Universe?
Interstellar travel is horrible-what with the cramped quarters of your spaceship and only the thin hull separating you from deathly cold and deadly...

What Supernova Distance Would Trigger Mass Extinction?
The deaths of massive stars results in one of the most beautiful and violent events in the universe: the supernova. They are so luminous we can see...

Did AI Prove Our Proton Model WRONG?
The humble proton may seem simple enough, and they’re certainly common. People are made of cells, cells are made of molecules, molecules are...

Does Axionic Dark Matter Bind Galaxies Together?
Quantum mechanics is our best theory of the fundamental nature of reality, but it's usually only distinguishable from familiar classical mechanics on...

What If The Speed of Light is NOT CONSTANT?
One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can we really be sure that the...

Was the Gravitational Wave Background Finally Discovered?!?
A few weeks ago a large team of gravitational wave astronomers announced something pretty wild. The moderately confident detection of pervasive...

Do We Need a NEW Dark Matter Model?
We have no idea what dark matter is, other than it’s some source of gravity that is completely invisible but exerts way more pull that all of...

Did JWST Discover Dark Matter Stars?
We knew that the James Webb Space Telescope would find interesting stuff, especially about the mysterious early times. For example, there are hints...

What If Space is NOT Empty?
Spacetime on its smallest scales is a seething ocean of black holes and wormholes flickering into and out of existence—or so many physicists...

What NEW SCIENCE Would We Discover with a Moon Telescope?
In order to see the faint light from objects in deepest space, astronomers go to the darkest places on the planet. In order to listen to their quite...

Are Room Temperature Superconductors IMPOSSIBLE?
Superconductive materials seem miraculous. Their resistanceless flow of electricity has been exploited in some powerful ways—from super-strong...

Are Pilot Wave & Many Worlds THE SAME Theory?
It’s hard to interpret the strange results of quantum mechanics, though many have tried. Interpretations range from the outlandish—like...

The Farthest Star Ever Seen!
To understand where we came from—how earth, the solar system, the galaxy became what they are today—we need to understand the beginning...

Why Did Attosecond Physics Win the NOBEL PRIZE?
Whenever we open a new window on the universe we discover something new. Whether it's figuring out how to see to greater distances like with...

How Will We (Most Likely) Discover Alien Life?

What If Gravity is NOT Quantum?
The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close...

Does Many Worlds Explain Quantum Probabilities?
The 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...
