Could We Terraform Mars?
We already have the technology to bring humans safely to Mars and set up small settlements - or at least could do within a generation. But those settlements will need to be cocooned - shielded against the deadly cold, intense radiation,...

How Many Universes Are There?
The universe is big, but it’s peanuts compared to the eternally inflating multiverse. But just how many universes are there? What are they like? And most importantly, what can they tell us about … aliens? Imagine it: the observable part...

The Holographic Universe Explained
The holographic principle emerged from many subtle clues – clues discovered over decades of theoretical exploration of the universe. Over the past several months on Space Time, we’ve seen those close clues, and we’ve built a the...

Loop Quantum Gravity Explained
The holy grail of physics is to connect our understanding of the tiny scales of atoms and subatomic particles with that of the vast scales of planets, galaxies, and the entire universe. To connect quantum physics with Einstein’s general...

The Real Science of the EHT Black Hole
So, how do you take a picture of a black hole? The beast in question is the supermassive black hole in the center of this – the M87 elliptical galaxy. It has an estimated mass of several billion times that of the Sun, which gives it an...

Black Hole Harmonics
When physicists talk about black holes they’re usually referring to highly theoretical objects – static, unchanging black holes viewed from “infinitely” far away. This makes everything clean and simple enough to attempt the already...

Is Earth's Magnetic Field Reversing?
Earth’s magnetic field protects us from deadly space radiation. What if it were drastically weakened, as a precursor to flipping upside down? I mean, it has before … many, many times.. Spaceship Earth has a literal deflector shield. A...

What Caused the Big Bang?
Every astronomy textbook tells us that soon after the Big Bang, there was a period of exponentially accelerating expansion called cosmic inflation. In a tiny fraction of a second, inflationary expansion multiplied the size of the...

How Black Holes Kill Galaxies
Black holes are really only dangerous if you get too close. Ha, who am I kidding. It turns out they may be responsible for ending star formation across the entire universe. When we first realized that black holes could have masses of...

Did Time Start at the Big Bang?
Our universe started with the big bang. But only for the right definition of “our universe”. And of “started” for that matter. In fact, probably the Big Bang is nothing like what you were taught. A hundred years ago we discovered the...

The Alchemy of Neutron Star Collisions
Carl Sagan’s famous words: “We are star stuff” refers to a mind-blowing idea – that most atomic nuclei in our bodies were created in the nuclear furnace and the explosive deaths of stars that lived in the ancient universe. In recent...

Is Pluto a Planet?
You know what a planet is, right? A big round thing that orbits a star. Uh, not so fast. The surprisingly vicious debate over the planetary status of Pluto has given us a fascinating glimpse into what a scientific definition really is....

No Dark Matter = Proof of Dark Matter?
We’ve been failing to detect dark matter for decades. Finally, the latest failure to detect dark matter may have actually proved its existence. One of these is true: either most of the matter in the universe is invisible and formed of...

What Happened Before the Big Bang?
We actually have a pretty good idea of what might have happened before the Big Bang. That is, as long as we define the Big Bang as the extremely hot, dense, rapidly expanding universe that is described by Einstein’s equations. That...

How 3D holograms work
Holograms are photographic recordings of 3D scenes. Unlike a camera, which captures one view through a small viewer focused by a lens, holograms capture an entire light field which allows them to recreate the 3D scene. Shimmery 2D...
