PBS: Space Time | Are We Living in an Ancestor Simulation? ft. Neil deGrasse Tyson

The idea that our reality is a simulation is not as far-fetched as you may think. Many philosophers, scientists, and tech-billionaires are seriously considering not just the possibility but the high probability that our civilization may be a program being run by another, more advanced alien civilization.  

The Oh My God Particle | Space Time

This episode of PBS Space-Time features the God Particle! Cosmic rays aren’t actually rays at all, but atomic nuclei traveling at close to the speed of light. Typically they are low in energy and are easily deflected by other particles, but on rare occasions an incredibly powerful atomic nuclei strikes the Earth’s surface. The largest …

PBS: Space Time | Have They Seen Us?

Are aliens watching Earth TV? We’d like to credit the SKA Organization for the image used in the thumbnail.  

PBS: Space Time | What Happens at the Event Horizon?

What really happens when you approach the event horizon of a black hole? What do you see when you actually cross it? Matt shows you an elegant tool for understanding this mysterious region of spacetime.  

PBS: Space Time | Pilot Wave Theory and Quantum Realism

There’s one interpretation of the meaning of quantum mechanics that manages to skip a lot of the unphysical weirdness of the mainstream interpretations: it’s de Broglie-Bohm pilot wave theory.  

PBS: Space Time | Did Dark Energy Just Disappear?

Did all of dark energy just vanish? A team of scientists have just analyzed new data and claim that we need to completely rethink its existence. PBS Space Time is once again talking about dark energy. A team of researchers has announced a new analysis of updated supernova data. They claim that the data are …

PBS: The First Humans on Mars | Space Time

NASA recently announced that they plan to have astronauts in orbit around Mars within 25 years. Not to be outdone, Elon Musk boldly stated that he could prepare a mission to Mars within 10 years. Musk’s SpaceX plan would transport a hundred people to the red planet. Their mission wouldn’t be to visit Mars but …

PBS: Black Holes from the Dawn of Time | Space Time

Primordial black holes may be lurking throughout our universe. How large are they, how many are out there and what would happen if they moved through our solar system? Scientists believe that many black holes may have been created at the time of the Big Bang and and are still roaming our universe today. If …

PBS: | Space Time | Are We Alone? Galactic Civilization Challenge

The Drake Equation tells us the likelihood that there are other advanced technological civilizations waiting for us among the stars. In this episode of Space Time we challenge you to use the Drake Equation to help us determine how near or far these alien races may be. Everything we’ve learned about our universe tells us …

PBS: Space Time | Quantum Entanglement and the Great Bohr-Einstein Debate

Albert Einstein strongly disagreed with Niels Bohr when it came to Bohr’s interpretation of quantum mechanics. Quantum entanglement settled the argument once and for all. Einstein argued that elementary particles maintained their intrinsic values whether they were being observed or not. Bohr believed that in observing such particles we collapsed a wave function of probabilities. …

PBS: Space Time | Self-Replicating Robots and Galactic Domination

Self-assembling robots are referred to as von Neumann machines after the man responsible for originally proposing them, John von Neumann. Since then, the potential of these machines and their ability to proliferate throughout known space has made galactic colonization seem not only possible but perhaps inevitable.  

PBS: Space Time | Is There a Fifth Fundamental Force? + Quantum Eraser Answer

Has a fifth fundamental force been discovered and how will this effect our understanding of the universe? A laboratory in Hungary has has witnessed a startlingly strange reaction between Beryllium-8 atoms. It seems to point to the existence of a fundamental force beyond the four we already know. And this new force may have something …

PBS : The Future of Gravitational Waves | Space Time

Find out how gravitational waves are allowing us to unlock the secrets behind black hole formation and growth. 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 …

PBS: Space Time | Juno to Reveal Jupiter’s Violent Past

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. In this episode, find out how Jupiter wreaked havoc through …

PBS: Is Quantum Tunneling Faster than Light? | 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. This is only one way that quantum mechanics challenges our perception of reality. Matt dives into these counter-intuitive ideas and explains the bizarre phenomenon known as quantum tunneling in this episode of …

PBS: Nucleosynthesis | Space Time

Joni Mitchell was right, we are stardust. Stars are our stellar alchemists. They spend their entire lifespan creating and molding elements. In their final moments, a supernova spreads these elements out into the universe, providing the building blocks for new stars, planets, and even us!  

PBS: How Cosmic Inflation Flattened the Universe | Space Time

Although much of the Big Bang Theory is widely accepted to be true, it only gets us part of the way there. Observable truths such as the CMB and the flatness of our universe reveal that there is no way the universe has been expanding at a constant rate since its beginning. It turns out …

PBS Digital Studios: Space Time | Why is the Earth Round and the Milky Way Flat?

Our universe is not a very diverse place when it comes to shapes. Large celestial bodies become spheres, galaxies become discs, and there is little room for variation. Why is this? Well it turns out physics has some pretty strict rules when it comes to creating new planetary bodies. On this week’s Space Time, the …

PBS: Space Time | What’s Wrong With the Big Bang Theory?

There’s a problem with the Big Bang Theory. Now that we have a primer on the aspects of the Big Bang Theory that we know definitely happened, let’s look further into what we don’t yet know, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum …

PBS: Space Time | Will Mars or Venus Kill You First?

Which is the deadlier planet: Mars or Venus? Humans have been talking about space colonization for quite some time, but our neighboring planets are not exactly the most hospitable places. If we are ever going to be successful, we should probably figure out where we could reasonably expect to survive. In this episode of Space …
