Neil deGrasse Tyson's Skepticism Over UFO's

the jurogan experience and in another case i saw it was a magpie one of these birds known for how smart it is there is a full uh uh you know half liter um you know plastic uh thing of water it was just water okay you know a water bottle and it was full so the magpie goes over and sips out the water now you can ol the beak is only what an inch and a half long or an inch at most so it goes in until it can't reach the water anymore so what does it

do it goes off to the side gets a rock just the right size drops it into the water bottle it raises the level thereby displacing water here it is that is you've got the there it is and so it comes and it goes back and gets another stone drops it in and every time it drops it in the water level rises and it can drink more water and it just it keeps doing this that's pretty amazing okay and so so every time we study animals they're smarter than we ever thought they were so maybe for

our own ego we kept building ourselves up saying how separate and distinct we are as humans in the animal kingdom when maybe we're not as separate and distinct as we think we are so now what's my broader point there about that i was making i just distracted something about ufos yeah i know i'm just trying to get back to ufos on that the the fact that we have high resolution cameras in our pocket we take videos of things that are very unusual so exactly so here's video of a magpie doing bernoulli experiments on a on

a on a water in a water bottle who would have known that even happened right right okay you can't bring the bird into a lab and and then maybe you could but i don't know that anyone did all right here's my point um in the 1960s and 70s there were many many reports of alien abductions people said the aliens came to me and they brought me in and then they released me do you have any footage no they took my camera or no they zapped my my film and now there's no image on the film

but there were countless stories well now you can stream live from your camera anything that's going on in front of you so if the aliens come and they want them duck you stream it that would be instantly viral oh my gosh you know the stuff that goes viral is much less than that a cat that a kitten that jumps to the table and falls that goes viral you don't think of video footage of an alien is not going to go viral instantly but there's none so i'm just saying i'm thinking if we were being visited

somebody would have some good footage if we were being visited i'm thinking maybe google satellite images would catch spaceships that are not airplanes moving on our surface if we were being visited i i'm thinking we'd have something better than fuzzy monochromatic video of of of objects that apparently reveal themselves only to navy pilots right so one of the reasons is most of these sightings actually occur far offshore in the ocean and the speculation is this is one of the ways no obviously i'm gonna put my tin foil hat on nice and tight do your thing

this is one of the ways that they monitor us the best way to do it is to do it where they're hold their base where no one is around which is the ocean no that's not true they go in the ocean they pop up and they fly that's not true what do you mean it's not true it's not true yeah nobody lives on the ocean yes that's correct but have lives down under siege this is what the speculation okay that's why these trans-medium devices have been okay these trans medium crafts have been observed if you

want if you are sure we are being visited by aliens and you don't actually have really good evidence then you have to say that sure well you know that you have to say that you have to say this is really happening and they're observing us and they're concealing themselves in this particular way you have to say that so that's the that's sort of that's your way to maintain your your your alien belief system by saying that and i don't have a problem with it go get him go get him but all of what has been

put forth as evidence for aliens to me is insufficient evidence to excite my interest my research interest in devoting time to finding it out but it definitely has excited other people i have not stopped them i am not saying defund the military uh program on uaps which of course is just updated ufo i know they like to say that now because it's like a stigma too i know that's just that that's a really transparent sneaky way no no it's not even sneaky it's actually i think it's embarrassing it's like maybe if we call them uaps

people take them seriously no i'm of the belief that they're probably akin to what we did on mars i don't think there's aliens in them i have a feeling that these things are probes and i feel like if you just think about biological entities flying through the universe like why do that right when you have sophisticated technology that's good enough right now from our like relatively primitive in consideration of what we think is possible a million years from now right but we can send that mars rover around we have a helicopter on mars i mean

there's multiple satellites flying through the universe right now taking images we we can do all that yeah but now our probes are not targeting the martian military fighter because there's no martian military but if there were we certainly wouldn't hang out in the open right but if we had something like are you familiar with um one of the most famous cases was a case with uh commander david fravor of the navy who uh encountered with one or two other jets off of the nimitz they encountered this thing that was shaped like a tic tac you

know everybody knows this yeah this story it went from they tracked it going from 80 000 feet above sea level to 50 in less than a second they have no idea how it moved there's no visible propulsion system it was blocking their radar it was actively blocking tracking this is what their sensors yes told them exactly just be clear about that and then you're stating information as though it is fact i'm stating information as commander for i don't care that doesn't matter he's human right and we're all human here but as a scientist when you're

presenting information you don't say this thing was at 80 000 feet and it dropped to zero to sea level in one second or whatever it was the the measure that's that's the wrong way to report it what you say is we have sensors that told us this is what happened i understand what you're saying okay yeah that's a very important distinction yes and so so now all right your first question then tell me about the sensors yeah okay or are they double checked are they you know that and so so but if you're just gonna

say there's this craft at 80 000 then you everyone is thinking about a craft and no one is thinking about the sensor they actually saw with their eyes too this is something that they actually you can't see something at 80 000 feet no the the the actual visual on the crowd okay they didn't see it at 80 000 feet but this craft it's not just something that was tracked with equipment got it but they didn't see it at 80 000 feet that's my point so so uh by the way this level of that of that

of of attention i'm giving to the detail and the reporting of information we do that with fellow scientists for much less oh for sure than if we're being visited by intelligent aliens from another planet go visit a go go to a scientific conference and watch the level of scrutiny we put on other people's work if they have a sensor that has a new result we'll say did you calibrate the sensor did you how long has the sensor been in use what uh a given example here's an example okay um do you remember planet x yes

the search for planet x nibiru uh that was one uh there was sorry there were several incarnations of planet x right that was among them okay that was i'm talking i'm talking about a hundred years ago planet x okay thanks a few hundred years ago well there's several planet x's right so um uranus was moving weirdly nobody understood maybe there's a planet beyond it whose gravity we have yet to reckon in our equations up boom we discover neptune wait a minute neptune is moving a little a little uh unfamiliarly this is why my phone is

sorry about it you're gonna drop that thing and break it with no casing so yeah this i got the 12 and yeah i can still do this i'm just sorry yeah i get it last time you were here you had a broken case you're a broken back remember so uh why are you distracting me i was like on a roll and neptune neptune so so neptune we're looking at neptune's orbit and it's not following newton's laws and this is odd well we've been down that road before uranus didn't follow unions laws we proposed another planet

and we found it so neptune's not following all the laws of gravity that from all the other planets in the sun there must be another planet out there a planet x let's look for it is that bodes law bulesi is a is a fitting function that gets you it it got a little more attention than it deserved it's just that planets um every next planet is about twice as far away from the sun as the previous one so you just make a quick equation out of that and that's but it doesn't work for mercury and

it didn't work for pluto and i thought it was based on the mass of the planet no not at all and mass has nothing to do with it and it predicted the asteroid belt but the estrogen belt there's no planet there right okay and if you add if you glue together all the pieces of the asteroid belt you get something like five percent the mass of the moon so yeah it gave us the location of the astro belt but that's not a planet so bode's law it's fun to play with but you know there are

limits to how far you want to uh declare its relevance to the actual universe so we're out here at neptune and so it's as i said maybe there's a planet x everybody started looking everybody started looking including percival lowell all right back in the 1920s and he said i want to find planet x because something's perturbing neptune so he sets out looking for it and he doesn't find it then he hires clyde tombaugh and he dies so he doesn't see the results of this clyde tombaugh said i can't find it either i will just systematically

search everywhere because if you think something's affecting you gravitationally you ought to have some idea where it is to be tugging on you in that way right that's not that's not some kind of weird it's it's like you're moving differently where must the thing be to tug on you so that you're moving in that way no one could find such a planet x so clyde tombow said it's got to be out there somewhere i will systematically image the entire sky all right you got to do it on multiple nights because if something's moving you'd see

it change from one picture to the next he does this discovers pluto was pluto where planet x was supposed to have been no was pluto the mass that planet x should have been everyone assumed it was but over the decades the mass of pluto got lower and lower and lower as our estimates got more and more accurate then we found out that pluto is is one-fifth the mass of our moon made of half ice and this is why pluto got into trouble later in the in the 20th century it's not it's not because we had

some vendetta against pluto pluto just never belonged in that list to begin with that's really how you need to think about it anyhow there's still the matter of neptune's orbit pluto did not have enough mass to make those changes so the search for planet x continued so what happens all right uh 1993 a colleague of mine named miles standish okay he's probably related to the mile standish on the mayflower he is an astrophysicist looked at all of the data people were using to say neptune's orbit was crooked looked at all the data then he found

out that at one particular observatory was it the gearbox or the timing mechanism had just been cleaned or swapped out or there was some because in the observing log you write down everything because you just don't know okay was there a glitch in the current was there a bird fly over you make notes of everything one of the observatories whose data was being grafted together with the other observatories had this sort of gearbox but i don't remember it was a gearbox there was some mechanical adjustment that was made he said i wonder if that had

an effect on the positioning of this telescope he removed those data from his analysis and fitted data to all the other telescopes that he had for the positions of uranus of neptune when he did that planet x evaporated in that instant in that instant there was no planet x all the other data when it connects across removing the data from the one where the observing log said they did something different uh uh neptune fell right on to newton's laws and so so since 1993 there is no planet x and pluto and and we're it not

for that we probably would have been a long time before we discovered pluto because no one would have looked for it they found another like let me just finish the lab the lesson there okay the lesson there is you have information that you think is correct from your sensors this was an observatory a fine observatory and you're gonna say this observatory says neptune is misbehaving but then you learned there was something wrong with the data you throw it out so uh so i'm just i'm trying to say this happens all the time in science you

have to be careful what you're analyzing before you declare that what the thing measured is true and then realign all your resources to address what you think is true when it might have just simply been a glitch or multiple glitches or anything and we do this all the time in science catch new episodes of the joe rogan experience for free only on spotify watch back catalog jre videos on spotify including clips easily seamlessly switch between video and audio experience on spotify you can listen to the jre in the background by using other apps and can
