Did you hear the story about how a 100 petawatt laser will finally ‘break the quantum vacuum’? Get the facts. Empty space, as it turns out, isn’t so empty. The fluctuations […]

What it would take to make a ‘mirror Universe’ a reality. The idea of parallel Universes has been around for over 60 years now, giving a theoretically physical existence to all […]
Do these five experiments right in your own living room, and explore some of the most baffling phenomena in all of nature. It’s a revolutionary idea that the Universe is made […]
Last week, the crew found themselves in the mirror Universe. Here’s what science has to say about that. Star Trek: Discovery entered their midseason hiatus on a terrific cliffhanger: they had […]
Having ‘high levels of intelligence’ is no excuse for rejecting quality scientific information. You think of yourself as a generally intelligent person, don’t you? Someone who’s good at deducing fact […]
Out of five vital questions, which one should we most desire the answer to? Despite all we’ve learned about physics, science, and the Universe before us, there are still some incredibly […]
Perhaps energy isn’t conserved at all in an expanding Universe. If you have a Universe full of stuff — whether that’s atoms, dark matter, radiation, neutrinos, or anything else — it’s virtually impossible to […]
There are plenty of questions we don’t know the answer to. With quantum gravity, they might be solved! This article is written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized […]
Physicists make a new discovery in quantum mechanics, showing nanomagnets can levitate despite a classic theorem that said it’s impossible.
It will be the most extreme test of Einstein’s General Relativity ever. And we already have the data. With every year that goes by, the total amount of knowledge that humanity […]
Ever think you’d see a single atom without staring down the barrel of a powerful microscope?
The deep dive into the mirror Universe, and the ethics of how we deal with purity and diversity, is just getting started. Life in the mirror Universe isn’t easy for anyone. […]
The Universe began almost perfectly uniform, while today, it’s anything but. Here’s how we grew up. One of the strangest facts about the Universe is how dramatically its changed over time. […]
If you’ve ever wondered which part of physics covers which part of space, fret no more. Here is an awesome map that lays it all out.
A new look at the intertwined lives of two of the 20th century’s greatest minds. In the years prior to World War II, physics was in an odd, post-revolutionary state. Quantum […]
And what do we still have left to learn? The original idea of a black hole goes all the way back to 1783, when Cambridge scientist John Michell recognized that a […]
Do we need quantum gravity? We sure do… and here’s how we’re trying to get there! Our current best theories describing the Universe, general relativity for gravity, quantum field theory for […]
Here are some of the most impactful scientific achievements in a year full of discoveries.
Nothing can go faster than the speed of light in a vacuum. But particles in our Universe can’t even go that fast. When it comes to speed limits, the ultimate one […]
The densest objects in the Universe are also the most difficult to destroy. But eventually, destruction always prevails. There are quite a few ways to make the black holes we […]
How Nelson Mandela, quantum mechanics, and the Internet combined to provide evidence of parallel universes.
It’s so much more than mass-energy equivalence; it’s the key to unlocking the quantum Universe. For hundreds of years, there was an immutable law of physics that was never challenged: […]
Lasers, mirrors, and computational advances can all work together to push ground-based astronomy past even the limits of Hubble. One of the most profoundly remarkable properties about our atmosphere is that […]
Even our scientific heroes can’t be right about everything. Let’s learn the lessons that they never did. In the 1960s, a young theoretical physicist named Stephen Hawking rose to prominence as […]
Surprisingly, the evidence points towards the existence of the unobservable multiverse. But it isn’t the answer you’re looking for. “We are all agreed that your theory is crazy. The question that […]
How precise can measurements get? Imagine accurately measuring a quartz crystal with merely a few photons.
These cosmic behemoths were enormous from very early times. Here’s how they came to be. One of the biggest challenges for modern astrophysics is to describe how the Universe went from […]
Hubble holds the record, finding a galaxy when the Universe was just 3% it’s age. In just a few years, James Webb will shatter it. One of the great scientific lessons […]
Edward Witten is a genius among geniuses.
