    Neil deGrasse Tyson and Sean Carroll Get Philosophical About the Universe
    Apr 12 2024
    Why is there something instead of nothing? Neil deGrasse Tyson and Sean Carroll go deep when talking about this philosophical question. Are there models of the universe that give us the answer?
    Are there parallel universes? Sean Carroll gives us a lesson on the Many-Worlds Interpretation of the universe. What is the role of the observer in quantum mechanics and how does it explain things like the "double-slit experiment"? Are there ways to experimentally verify 'Many-Worlds'? Find out during this podcast highlight.

  • The Time Neil Was Almost Struck By A Meteorite

    The Time Neil Was Almost Struck By A Meteorite
    Apr 12 2024
    Neil deGrasse Tyson recalls a story of an almost deadly brush with fate he had one night while looking up. He recounts it as "the most alarming thing he's seen in the night sky." This and much more in this StarTalk+ video.

    What would alien inhabitants of the Andromeda Galaxy see if they looked in our direction? Can they see our galaxy with the naked eye? What about planets? How come some, like Uranus, rotate in the opposite direction? Neil explains all this and more to comedian Russell Peters in a discussion that is equal parts hilarious and mind-bending.

  • Why Our Universe Exists in Three Dimensions?

    Why Our Universe Exists in Three Dimensions?
    Apr 12 2024
    Are the constraints imposed by a third dimension the optimal organizing force in our universe? What would happen if we inhabited higher spacial dimensions? Neil deGrasse Tyson and Janna Levin try to wrap their head around the implications of dimensions—both large and small—in this profound highlight. Is it possible that the universe is a loop, and that light from earlier versions of ourselves keeps making its way back to us? Are we simply seeing a reflection when we see young galaxies in the distance? Find out on this mind-bending highlight from StarTalk+.

    Neil deGrasse Tyson and Brian Greene Discuss The Problem with String Theory
    Apr 12 2024
    What's taking String Theory so long? Brian Greene explains just why figuring out the universe is a more complicated task than others might suspect. Are there limits to a human being's ability to fully comprehend the universe? Will we ever overcome those barriers? Find out on this Podcast Highlight as Neil deGrasse Tyson and Brian Greene go deep on the subject.

    Are Aliens Sending Encrypted Messages?
    Apr 12 2024
    In this video, Neil deGrasse Tyson discusses the mysteries of our universe and secret alien communications with 'geek-in-chief', Dr. Charles Liu.

    What's really causing the expansion of the universe? Dr. Liu suggests alternatives to Dark Matter, including the possibility that our universe is just a bubble in a larger universe.

    Why is gravity so weak? Dr. Charles Liu goes into depth about the mysteries of the Gravitron and how to square concepts from general relativity with quantum mechanics. How does time behave while approaching the speed of light? Could the fabric of spacetime be weaved by wormholes?

    Should we fear AI? Dr. Charles Liu gets deep as he questions the way humans value themselves in a future dominated by AI. What skills do we need to learn to retain our value in the workforce.

    Is there life elsewhere in the universe? Are aliens encrypting their messages to hide from us? Neil and Charles ponder deep questions about potential alien ancestors and extraterrestrial contact.

  • Why Quantum Physics Says There's a Multiverse

    Why Quantum Physics Says There's a Multiverse
    Apr 12 2024
    Who wins in a battle between General Relativity and Quantum Physics? The answer has pretty serious implications for our view of the universe. Do we live in a continuum across an infinite number of parallel universes? Neil deGrasse Tyson has got an answer that might surprise you.

    What came before the Big Bang? Neil explains why such a question has no meaning. Was the singularity at the beginning of time embedded in a higher-dimension? And what does that mean for our ability to understand the universe?

    Where did the ingredients for life come from? Neil explains why it takes so long to make said ingredients, and offers a perspective on areas of the universe that are teeming with life.
    Why is everything round? Neil offers insight into the forces that shape our universe... into mostly round things. Why are there exceptions? Find out in this episode.

    The New Telescope Looking Back to the Beginning of Time
    Apr 12 2024
    In this video, we revisit our recent conversation with Jason Rhodes, the NASA JPL researcher working on the Euclid and Nancy Grace Roman Space Telescopes.

    What is the Dark Universe? Neil DeGrasse Tyson tries to arrive at a better name for the mysterious substances making up 95% of the observable universe. Rhodes also explains how the Euclid and Nancy Grace Telescopes are looking back through time to create our most nuanced map of the universe to date.
