Are alien spacecrafts here on earth? In this explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice discuss the existence of aliens on earth and what the scientific community thinks of it.
Do conspiracy theories like UFOs hold any truth or validity? Or is this obsession with aliens just fueled by the movies? Find out what T-Rex, blackholes, and the brothers Grimm have in common. We also debate whether imaginings of evil aliens are just based on how we humans treat each other. Are the people being visited by aliens always the ones in danger?
What do aliens look like? Learn why we often portray aliens as being vertebrate. Would advanced aliens capable of space travel even care about us? You’ll learn how alien sightings have changed over the years with the innovations in photographic technology. We explore the leaps many people take when they discover things in the night sky. Are human senses even trustworthy without further evidence? Is the government competent enough to keep this a secret? All that and more on another StarTalk explainer!
