Neil deGrasse Tyson: Want to prove aliens exist? Do this.
Neil deGrasse Tyson wants to believe. He just needs to see the evidence first.
Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia. He is the first occupant of the Frederick P. Rose Directorship of the Hayden Planetarium. His professional research interests are broad, but include star formation, exploding stars, dwarf galaxies, and the structure of our Milky Way. Tyson obtains his data from the Hubble Space Telescope, as well as from telescopes in California, New Mexico, Arizona, and in the Andes Mountains of Chile.Tyson is the recipient of nine honorary doctorates and the NASA Distinguished Public Service Medal. His contributions to the public appreciation of the cosmos have been recognized by the International Astronomical Union in their official naming of asteroid "13123 Tyson".
Tyson's new book is Letters From an Astrophysicist (2019).
NEIL DEGRASSE TYSON: There are many people who see things in the sky and are sure – they can't explain it, so they're sure it's aliens visiting. Well, if you were really, really sure of that, you are not likely to write me a letter. Unless you're writing me a letter to convince me of your point of view. But that doesn't make for a fertile exchange. If you see lights in the sky and you don't know what they are and you want further insight on what they could be and write me a letter, that's a meaningful exchange.
If you can't explain what it is and it's flying and it's an object, it's an unidentified flying object, period. You just said you don't know what it is so that sentence should not continue beyond that phrase. You can't say I don't know what it is, therefore, it must be aliens visiting from another planet. If you don't know what it is it therefore must not be anything.
Okay, so maybe we are getting visited by aliens daily. In all of these sightings, it's aliens. I don't have a problem with that. My issue is what you are presenting as evidence in support of that claim. If it's entirely grounded in your eyewitness testimony you need to know that eyewitness testimony on the totem of weight of evidence it is at the bottom. A little scary because in the court of law it's considered pretty high evidence. People say, "I need a witness!" No, you want data. That's what you really want. You want information that didn't have to pass through someone's sensory system so that you can minimize bias, delusion, the filtering that we always do as the world outside of us comes through our senses for us to then decide what is and what is not going on around us. It's why we invented science. So that we wouldn't have to depend on our senses as the ultimate measure of what is or is not true in the world.
Science and its methods and tools. The telescope, the microscope, the recorders, chart recorders, all of this. So, the best thing is—and by the way, I don't care what your pedigree is. I don't care if you're a military colonel, pilot, Air Force. Are you human? That's all that matters. After that give me better evidence. And yes, Carl Sagan's famous dictum, "extraordinary claims require extraordinary evidence." So the best thing is to drag the alien into town square and you'll be rich and famous overnight. You don't have to argue with me. I'm not stopping you. Go ahead. But do you know what's more significant than that fact is that today, worldwide, we are uploading to the internet a billion photographs a day. Everyone has a camera and a video camera. Remember all those reports of people getting abducted and poking their gonads? Where's the video of that today? You can film that and stream it to the internet while it's happening in case they snatch it from you. Because these aliens they don't want a record of this of course.
Where's all the video? Where are the images of you posing for selfies with the aliens? I don't see that. That would be very helpful starter evidence that you're experience was real and don't require that I have to depend on your eyewitness testimony to decide what is or is not true in this world.
You know what would make good data? You're in the flying saucer or whatever it is they came here in. Tell them to "look over there!" and while they look away snatch something off the shelf like an ashtray or something. I don't know if the aliens smoke. Snatch something. Anything off an alien spaceship is going to be interesting. Anything. I promise. And then you've got something to bring to the lab if you can't drag the alien itself. Then we can talk. Until then spend more time getting better evidence than trying to convince people that they exist in the absence of it.
- Are UFOs actually alien spacecraft visiting Earth? They might be, says Neil deGrasse Tyson, but if you want to make that claim you better bring the evidence to support it.
- Eyewitness testimony is the lowest form of evidence. To measure what is true or not true in the world, we require data -- and when it comes to alien appearances, it's as astronomer Carl Sagan said: "Extraordinary claims require extraordinary evidence."
- So what can you do to prove your alien abduction story? Take selfies, live-stream video to the internet, and if you happen to find yourself in a spacecraft getting your "gonads poked", then grab an item from the alien lab as evidence before they release you back on Earth. Neil deGrasse Tyson wants to believe, but not until he sees the data.

Does the President get to decide when to ignore the law?
- During the Civil War, Abraham Lincoln decided to suspend habeas corpus, a protection in the Constitution that prohibited imprisonment without a trial.
- From Lincoln's point of view, following the law to the letter during that unprecedented and pivotal moment in history (i.e. the threat of war and secession from the Union) would put lawfulness itself at risk, so some restrictions of civil liberties were necessary.
- The war and the president's actions changed how the founding document is interpreted and sometimes challenged by the rule of men.
Is information the fifth form of matter?
- Researchers have been trying for over 60 years to detect dark matter.
- There are many theories about it, but none are supported by evidence.
- The mass-energy-information equivalence principle combines several theories to offer an alternative to dark matter.
Whether or not women think beards are sexy has to do with "moral disgust"
- A new study found that women perceive men with facial hair to be more attractive as well as physically and socially dominant.
- Women tend to associate more masculine faces with physical strength, social assertiveness, and formidability.
- Women who display higher levels of "moral disgust," or feelings of repugnance toward taboo behaviors, are more likely to prefer hairy faces.
