The Kepler telescope recently noticed a strange partial eclipse that some have speculated could be a Dyson Sphere. Are Dyson Sphere's possible? Are they practical? What other alternatives to futuristic energy capture do we have to choose from?

Causality is meant to move in one direction: forward. But the Quantum Eraser experiment seems to reverse causality. How and why can this happen and what are the implications of this experiment on how we understand Quantum Mechanics and our greater universe?

What do we do to protect ourselves from extinction level events? And what if some of those events are unavoidable? Can we survive adrift in space? Find out in this episode of Space Time.

The double slit experiment radically changed the way we understand reality. Find out what the ramifications of this experiment were and how we can use it to better comprehend our universe.

On September 14th, 2015 LIGO announced the first detection of a gravitational wave. This was hailed at the time as the dawn of gravitational wave astronomy. However that’s only true if the we ever detect another gravitational wave. Now we have. On December 26th LIGO again observed the merger of two different black holes.

On July 4th 2016, the Juno spacecraft entered orbit around the planet Jupiter after leaving earth five years ago. The Juno probe will tell us what lies inside the mysterious gas giant and with this information we’ll better understand the formation of our solar system.

Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean and what are the incredible implications this fact has upon our reality? To find out check out this episode of Space Time where Matt digs into the early history of quantum mechanics.

In the world of our mind’s eye, light travels in a straight line. In reality, spacetime is deflected and magnified through the lens of gravity. Find out how this works and what it allows us to learn about our universe in this episode of Space Time.

Where are you right now? Until you interact with another particle you could be any number of places within a wave of probabilities. Matt dives into these counter-intuitive ideas and explains the bizarre phenomenon known as quantum tunneling in this episode of Space Time.

Throughout history, there has been much speculation about what the fate of the universe would be. Many theorized that the universe would eventually succumb to the pull of gravity, and reverse its expansion in what was being called ‘The Big Crunch.’ However, with the help of mathematical equations from Newton, Einstein, and Alexander Friedmann, we now have an answer.
