The Geometry of Causality

In this episode we dive deeper into the relationship between space and time and explore how we can geometrically map the causality of the universe and increase our understanding of how time and distance relate to one another.


The Real Meaning of E=mc²

You’ve probably known OF E=mc² since you were born, and were also probably told that it meant that it proved Mass equaled Energy, or something along those lines. BUT WAIT. Was E=mc² explained to you properly? Mass equalling energy is mostly true, but E=mc² actually describes a much more interesting, and frankly mind-blowing aspect of reality that likely wasn’t covered in your high school physics class.


The Speed of Light is NOT About Light

The speed of light is often cited as the fastest anything can travel in our universe. While this might be true, the speed of light is the EFFECT and not the CAUSE of this phenomenon. So what’s the cause?


The Higgs Mechanism Explained

Quantum Field Theory is generally accepted as an accurate description of the subatomic universe. However until recently this theory had one giant hole in it. The particles it describes had no mass! The Higgs field and the Higgs mechanism were proposed long ago in order to give particles mass, but it was only in 2012 that the existence of the field was proved with the discovery of the Higgs boson by the Large Hadron Collider.


The True Nature of Matter and Mass

We know that mass is energy… but what is energy? And where did matter and time even come from? Matt begins to dive into these intricate topics by first examining what inertial mass is, how it relates to gravitational mass, and what it all means for mass as a fundamental property.


What Survives Inside A Black Hole?

We’ve established by now that black holes are weird. The result of absolute gravitational collapse of a massive body: a point of hypothetical infinite density surrounded by an event horizon. At that horizon time is frozen and the fabric of space itself cascades inwards at the speed of light. Nothing can travel faster than light, and so nothing can escape from below the event horizon- not matter, not light, not even information.
