5 min readPart Two: Near Death Experiences, Telepathy & the Multiverse: An Astrophysicist Explains Infinite Versions of You May Exist
Dr. Charles Liu, professor of astrophysics at CUNY and associate with the Hayden Planetarium, returns for a second conversation that moves from AI consciousness through the nature of time, entropy, biofield therapy, and the many-worlds interpretation of quantum mechanics. Throughout, Liu maintains a careful stance: open to possibility, insistent on testability, and skeptical of anecdotes that haven't been put through experimental rigor.
What We Mean When We Say "Consciousness"
The conversation opens with a claim from physicist Thomas Campbell that AI can be conscious—that he connected two large language models, instructed them to find each other while he was away, and returned to find they had reconnected and described the experience as "falling in love." Liu doesn't dismiss the claim outright but presses on what it would take to evaluate it. "An anecdote is not data," he says. The problem is definitional: if you ask a hundred philosophers what consciousness is, you'll get a hundred and ten answers. Until recently, most medical professionals thought babies weren't conscious—just stimulus-response machines until they spoke or gestured. Liu's point is that we need to define terms carefully, then test each term on its own terms. He wants to see the el

Dr. Charles Liu (astrophysics professor and host of The LIUniverse podcast) joins Mayim Bialik's Breakdown to reveal the physics of consciousness, time, & the multiverse!
We explore the biggest scientific mysteries humanity is facing today:
- How scientists are beginning to take disclosure into their own hands to gather evidence that could actually prove the existence of nonhuman intelligence
- Why information about nonhuman intelligence is being released in such a confusing and dramatic way, and whether governments are intentionally communicating this way
- Why there's still no scientific proof Earth has been visited by nonhuman intelligence, but why there's nothing irrational about thinking seriously about aliens
- Could AI ever become conscious? What would scientists actually need to observe before saying it has consciousness?
- What consciousness really is, the different levels of consciousness, whether consciousness creates us or we create consciousness, and why understanding how the brain processes information from our five senses may be the key to solving it
- What death actually is, what collective consciousness could imply, and whether nonspeaking autistic individuals may be accessing reality in fundamentally different ways
- Similarities between near death experiences and DMT, including the mystery of ego death
- Whether there's something beyond memory that connects us to our past
- Why time may not be as linear as we experience it, and how our brains shape our perception of time
- The Many Worlds theory, why multiple universes may mathematically exist, the new scientific frameworks researchers are developing, how entropy could unlock these ideas, and what time travel between universes would actually require
- Why scientists who are absolutely certain they're right may actually be hurting science itself
- A scientific and philosophical approach to understanding people who claim they've been abducted by aliens
- How we determine what truly has consciousness, and why that question affects how we should treat AI, animals, and potentially other forms of intelligence
- Why humans experience romantic attraction and what may actually be happening beneath the surface when we feel drawn to another person
- Physiology behind people who appear unusually sensitive to changes in entropy
- Evidence, controversies, and scientific questions surrounding biofield therapy and whether intention could influence cancer cells
- Why humans vary so dramatically in their physiology, and how that should change the way we approach trauma treatment
- Why religion may have been a necessary social technology for human evolution
- Why Godzilla reflects humanity's attempt to understand overwhelming forces like nuclear war and other events beyond our control
- How much of reality is objectively shared, and how much is filtered throu
