Insiders Swear Alien Bodies Are in the Lab. Astrophysicist Investigates UFOs, & DMT | Neil deGrasse Tyson
June 23, 2026
AI Summary
5 min readIn 2023, Neil deGrasse Tyson watched a parade of ex-military and intelligence insiders testify under oath that alien bodies and crash saucers were being stored in government facilities and reverse-engineered. His response was not to join the chorus of belief, but to ask a single, deflating question: "Is it too much to ask to bring out the alien?" That question became the spine of his book Take Me to Your Leader, and in this conversation, he explains why the scientific community remains unimpressed by eyewitness testimony, why the mummified "aliens" displayed in Mexico's Congress were almost certainly a hoax, and how exponential human progress — not alien technology — accounts for the leaps in aviation and materials science that conspiracy theories attribute to reverse-engineering.

Show Notes
World-renowned astrophysicist Dr. Neil deGrasse Tyson (Author of Take Me To Your Leader: Perspectives on Your First Alien Encounter) returns to the Mayim Bialik's Breakdown studio for one of his most mind-bending conversations yet, covering UFOs, aliens, consciousness, near death experiences, secret government speculation, DMT entities, Antarctica’s hidden lakes, and what humanity may discover beyond Earth.
Neil reveals why he REFUSED an invitation to inspect an alleged alien body and explains what most people get wrong about extraterrestrials. He shares his biggest problems with how aliens are portrayed in Hollywood, why alien life may not need to be silicon-based, and whether stories about reverse-engineered UFO technology (including theories involving the Wright Brothers) hold any scientific weight.
He also addresses the mysterious deaths and disappearances of U.S. scientists connected to nuclear research and aerospace programs, and whether any of it could realistically be tied to nonhuman intelligence, UAPs, or classified technology.
The conversation goes even deeper into consciousness and altered states. We explore the controversial DMT laser protocol experiments and why so many experiencers report seeing the same “source code,” encountering entities, communicating with departed souls, or entering what feels like other dimensions. Neil explains the scientific evidence he would require before accepting out-of-body experiences or near death experiences as real phenomena existing outside the brain.
He also reveals why he has never used drugs, why he does not believe consciousness survives bodily death, and breaks down his fascinating “3 varieties of truth” framework for understanding reality itself.
Plus:
- What Neil deGrasse Tyson hopes humanity’s first contact with aliens would actually look like
- How aliens & UFOs became mainstream cultural topics
- Why he wanted to become part of the alien conversation
- Whether underground lakes beneath Antarctica could serve as models for icy alien oceans elsewhere in the solar system
- Future of astrobiology, extraterrestrial discovery, & human understanding of consciousness
This is one of the deepest and most controversial discussions Neil deGrasse Tyson has ever had on aliens, UFOs, DMT, consciousness, near death experiences, and the search for life beyond Earth!
