The Real Science of the EHT Black Hole

12th - Higher Ed
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...

The Cosmic Dark Ages

12th - Higher Ed
In astronomy we study things that are very far away. It’s a powerful challenge because even the brightest objects are almost impossibly faint when you view them from the other side of the universe. But there’s an up side. If the light...

Our Antimatter, Mirrored, Time-Reversed Universe

12th - Higher Ed
The foundations of quantum theory rests on its symmetries. For example, it should be impossible to distinguish our universe from one that is that is the perfect mirror opposite in charge, handedness, and the direction of time. But one by...

Building Black Holes in a Lab

12th - Higher Ed
Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we...

How Black Holes Kill Galaxies

12th - Higher Ed
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.

Could the Higgs Boson Lead Us to Dark Matter?

12th - Higher Ed
The discovery of the Higgs boson ten years ago in the Large Hadron Collider was the culmination of decades of work and the collaboration of 1000s of brilliant and passionate people. It was the final piece needed to confirm the standard...

Is 'Perpetual Motion' Possible with Superfluids?

12th - Higher Ed
The weird rules of quantum mechanics lead to all sorts of bizarre phenomena on tiny scales— particles teleporting through walls or being in multiple places at once or simultaneously existing and not. Shame all this magical behavior...

The Boundary Between Black Holes & Neutron Stars

12th - Higher Ed
When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and...

Is ACTION The Most Fundamental Property in Physics?

12th - Higher Ed
It’s about time we discussed an obscure concept in physics that may be more fundamental than energy and entropy and perhaps time itself. That’s right - the time has come for Action.

The Evolution of the Modern Milky Way Galaxy

12th - Higher Ed
When we scan the heavens with giant telescopes we see galactic cannibalism everywhere. We see moments that appear frozen on the human timescale, but are really snapshots of the incredibly violent process of galaxy formation. This is how...

What If Dark Matter Is Just Black Holes?

12th - Higher Ed
It may be that for every star in the universe there are billions of microscopic black holes streaming through the solar system, the planet, even our bodies every second. Sounds horrible - but hey, at least we’d have explained dark matter.

What Happened Before the Big Bang?
