https://www.youtube.com/watch?v=QN6r5yYnvwAJoin host Neil deGrasse Tyson, personal astrophysicist, alongside co-hosts Gary O’Reilly and Chuck Nice, for a special edition of StarTalk featuring celebrities and musicians asking their most curious cosmic questions.

In this episode, we dive into the inquiries that prove that deep “geek curiosity” is retained even by successful individuals in entertainment.

Questions & Cosmic Concepts Covered:

• Kevin Hart (Actor/Comedian): Is space capable of removing wrinkles from unironed dress pants? We explore the physics of steaming and how being close to a star might produce sweat that acts as a natural steam source.

• Tommy James (Musician/Singer-songwriter): Can drinking 8 O'Clock Coffee at 9:00 create a singularity? This discussion leads us to time zones and how the world contains 24 time zones.

• Nikki Glazer (Comedian/Actress): This two-part query asks: Is it 100% proven there is alien life? And is love real?.

◦ We establish that alien life is highly likely because the common ingredients for life on Earth (Hydrogen, Oxygen, Carbon, Nitrogen) are also the most common elements in the universe. However, NDT notes that just because the ingredients are in the supermarket, it doesn't mean the cake has been made.

◦ We use the "cup of water" analogy (scooping a cup of ocean water and concluding the ocean has no whales) to illustrate why we lack evidence, not existence, of extraterrestrial intelligence.

◦ Regarding love, NDT explains that while it may be described cynically as a chemical reaction, there is enough evidence in the conduct of our species to proceed without denying its reality. We also discuss whether other species, such as tortoises and roaches, exhibit joy and love.

• Jack White (Pop Icon): Is gold actually rare in the universe and on the planet we live on?. We find that gold is “rare but common”. Gold is extremely dense and sinks during planetary formation. We explore how gold and heavy metals are concentrated in metallic asteroids—which NDT calls "pre-sifted" material—and note that there is more gold in the ocean than has ever been mined on Earth.

• Cam Johnson (NBA Player): Can humans feel the change in spin speed between the equator (where rotation is thousands of miles per hour) and the poles (where rotation is slower)?. The answer is no, humans do not feel it, but the effect creates the Coriolis effect, which causes storms in the Northern Hemisphere to circulate counterclockwise.
