Heating of ice inside Oumuamua by the sun's rays causes evaporative loss on the sun-facing side, providing a slight acceleration as it leaves the inner solar system. Also this would cause a slight deceleration as it arrives in the inner solar system, as the dark side of Oumuamua consistently would not experience such an accelerative phenomenon.
Right! It's movements were "wobbly" and and unpredictable or should I say unexpected by many I'm sure when radiowaves were sent to try to make light (pun intended) of it. I wonder if it's evaporated water or ice but still maintains all the energy it has absorbed over time...maybe it's a proverbial garbage can.
@@sarahalhassen2902 yeah possibly! That is roughly how solar sail tech would work. Its oblong shape is probably the weirdest thing about Oumamoua. It seems like something that size and that thin would be torn apart by orbit unless somehow it's being artificially held together by engineering...
The alien spaceship hypothesis reminds me of a short story by Polish SF writer Stanisław Lem (for those who don't know: the author of "Solaris" book, later put to screen by Soderbergh). It was translated into English and published in a book titled "More Tales of Pirx the Pilot", the story itself titled "Pirx's Tale". I highly recommend it if you could get hold of it - the book was published in 1983. Lem's kinda famous about things that he wrote about as a fantasy or a potential future technology that eventually came to pass in one way or another (such as virtual reality). The moment I heard about Omuamua and a possibility (even if very remote) of it being an alien spaceship I thought: "Lem predicted that - again!". The Lem's story basically tells how easy we could miss an evidence of an alien civilization, if any such exists or existed, by pure bad luck.
I'm confused by the British lady she said that it was going so fast that it was never going to be pulled in by our sun but she also says it had an orbit
QUESTION: Is there any chance that one reason Oumuamua accelerated at some point after passing the Sun is because only the side facing back toward the Sun (at any point in time) would be the side being exposed directly to its radiation and therefore the side "ejecting" (either through sublimation or evaporation) material. If the object was light weight, it wouldn't take much to accelerate it. However, this would also mean it might've decelerated on approach but not as much (due to be larger in its approach).
It's vastly more likely that this is one of many millions of interstellar objects that have come by the inner solar system in recent geologic time, than it being the first.
Some changes are slow, some can be quite fast. Cliffs can tumble overnight. A storm can change the shape of a beach. An earthquake can leave lasting changes.
44:20 I feel like because it was in interstellar space and had no strong acting on it it must have been cut off a larger body by a super fast moving object that didn't do much damage when it cut through the larger body. Since it may not have had time to reshape itself it probably just shot through our Galaxy as a new formed shard of something
Theoretical concepts and new perceptions of Astro-physics especially excite me. I also am really intrigued by new discoveries made by human and machine!
They might after this video! Haha look at the comments its half about avi lol theyd be silly not to. Only thing i could see stopping them is the side that would criticize him. Hopefully theyre bigger then that but if not i still love them ( I know theres other people who have to accept it im sure)
@@DavidRice541 The problem with worrying about the people that would potentially criticize them for having Avi on is that those are the same scientists that Avi is pointing a spotlight on that have turned their scientific methodology into a kind of dogmatism.
Or maybe he was frustrated with his own people neglecting to be open minded and to fail which would further result in him needing a platform to burst out his anger that he kept with himself for his whole life ?

Always a pleasure to learn incredible facts about our universe and Chuck, I think you provide an earthy ' bad pun' humor that keeps me laughing and interested. I'd enjoy seeing you on stage. Good 👍 luck in your career 👍
i'm no geologist or physicist, but i see no reason why there wasn't a LOT of gold (and other heavy metals) at the core of the Earth. At those pressures and temperatures, the single differentiating factor that would separate elements is their density afaik. We have trouble finding gold exactly because of that, most of it has already sunken below, far beyond our wildest hopes of reaching.
19:48 That question is the most often asked about all kinds of events, which have only been witnessed once. The answer is: "We don't know. We can't know, not until we see at least one more. One measurement is no measurement!"
Oh, so that's why i have the feeling like, I've listened to this before 🤣 If i remember correctly, the audio only version of this already been posted on the "Neil deGrasse Tyson Office" channel...? Or Spotify maybe, I don't use Spotify.
Does the radiation in space cause objects to slow down similar to drag or friction and thus could Oumuamua slow down, in its trajectory and/or its spin/rotation and how long would it take?
A question to Nathalie : If the most dense metals sinck to the core , would GOLD not accumulate in the middle ? Or radioactive metals ? Was a great video /stream , well done Sir's ☆☆ Grtz Johny Geerts
Umm, are we not gonna talk about Oumuamua accelerating faster than it's presumed composition can explain? Must likely from solar winds. Something we've never seen naturally occurring rocks in our system do, something comets can only do if they exhaust and lose some of their composite particles which is evident by observing their loss of mass as well as the exhaust. That said, it is a behavior and acceleration we have seen man made space junk do? Seems odd we also omitted that it is incredibly shiny compared to most naturally occurring rocks in our system. Seems like a pretty huge details to omit when talking about it. Seems odd to dismiss the best fit examples we have, artificially man made junk can and does behave like this object, and that junk we've made can and does share unusually reflective properties. The 'naturally occurring' claim seems far more of 'requiring extraordinary evidence' when we mention everything we do know about it. The claim a thing shaped like nothing we've ever seen naturally occurring in our solar system or outside of it, that moves only like space junk we have made, is not interstellar space junk but is instead a naturally occurring never before seen shape, moving in a way we've never seen anything naturally occurring move that wasn't a comet that sheds mass when moving as such, unlike this object, reflects light in a way we have only seen our own space junk reflect... We must first prove it's not naturally occurring?? I'm sorry but if it looks like a duck and quacks like a duck and is shaped like a duck and moves like a duck and reflects light like a duck, why are we taking the Catholic Church inquisition model of 'it must be a zebra unless proven otherwise' position? If what we know for sure points most firmly at, 'there's a chance this is space junk from somewhere else,' I'm not clear why that cannot be equally plausible and ought not be given at least equal time as far as studying it. We already know a myriad of reasons, like distance and the passage of time to cover those distances, means we may never 2 way interact with another species from another system. However, it is plausible given the insane amount of space junk we've made in just a few decades that the likelihood of space junk flying in every direction from every system that once had space faring civilization is plausible at least. That's like a species that eventually gets intercepted by voyager saying, OBVIOUSLY we have to rule out naturally occurring because no way can intelligent life ever happen in another system. The moment we put stuff in space opens the possibility other life forms did the same at some point somewhere else. It is absurd that any human could immediately dismiss the possiblity this is something else's garbage, when the one thing we know for a fact is long after we destroy ourselves, our garbage will be around for much much longer. And the garage we have littered all over space will be around several orders of magnitude longer than that earth moon and Mars junk.
one theory i read about the shape of Oumuamua, was that it was created during title forces when passing a star in hot (kind of melting) conditions.. how possible is this?
We actually see the "rocks being light and floating" phenomenon in agriculture, where even though we remove rocks from a field, the neck year more rocks has come up to the surface. Atleast here in Denmark we call it "Moving Rocks"
That's freezing action on water in the soil, though. It basically only takes place because we till the soil; the effect doesn't bring rocks up from deeper than a couple of meters under the plough's cutting depth, and it's not happening where there's never a freezing winter ;)
If the object has the appropriate elements, could the collision itself provide a cauldron that results in the possible creation of building block molecules from those elements? I seem to remember an experiment that tried to reproduce such an impact and they did find building block molecules in the aftermath -- not sure at all about how well the experiment was designed and executed though.
MANY writers have been prescient about MANY things. Clark was also very prescient about geostationary satellites, three as a minimum, being used for radio transmission around the globe. There were not even rockets capable of injecting satellites into such an orbit at the time. SO MUCH technology had to be created before that actually happened. And Clark was a surprised as anyone when his idea was actually realized. And read Jules Verne's stuff too. His ideas of technology are not that close but WHAT might be done, and actually has been accomplished, is very close!

Is it not the case that a passing interstellar object/comet that grazes our atmosphere may exchange material with us without hitting us?can't remember the term I heard now.
2I/Borisov was an "ordinary, dusty-iceball"-comet from an unknown star-system. 1I/'Oumuamua was rare and special. I can't conceive, that Daryl Seligman's new hypothesis of an H2-iceball (Hydrogen-iceball) fits in Oumuamua's case. Although it could explain the unknown acceleration, it should have been evaporated at its sun-passage! Oumuamua was of "rocky"-material or even of metallic-composition, nickel-iron probably, so it had no problem sustaining the sun's heat. Please read Roman R. Raficov's paper 1I/'Oumuamua-like Interstellar Asteroids as possible Messengers from Dead Stars ... white dwarf-stars... in " The Astrophysical Journal " 2018 ApJ 861 35 . if a hot metallic core of a planetoid gets torn apart within the Roché-radius of a white-dwarf-star, this elongated shape of Oumuamua can easily be explained!
i wonder if the velocity of omuamua was exacly the scape velocity of our solar system, if it was before we detected that it boost a little bit, or after the boost,,or was way higher even without the boost...
Those ruled out are only the natural explanations that are known so far. There might be other explanations that could explain it that hadn't been discovered yet, and that explanation could be natural and yes it could be artificial.

@@ihaveguts I agree with you, what makes me even more mad is that they not only rule out the alien hypothesis, they make fun of basically everyone who dares to even consider it, I'd hope scientists were open minded people who consider any possibility until proven wrong.
Dr. Tyson, Can we use these objects that travel so fast in space and model our spacecrafts based off their movements? They’re not using fuel and they’re faster than we we can.
Hi: In 1975, I figure skated. I also weight lifted to obtain strength. I could squat (with a 2x4 under my heels to match the heel height of my skates). I could do 500 lb squats (one set of 6, sit on a bench, then stand up). If the packs in NASA weighed 200 lbs on earth, it would weigh only about 33 lbs. I weighed 185 lbs then. My foot weight with the 500 lbs would be 685 lbs. If I went to jump on a spring board, it would not happen (not enough physical strength to jump). On earth, I could jump 4 feet onto a spring board to go up about 6 feet. On the moon, the 500 lbs + my 185 lbs would only be 114 lbs. This should mean that I could jump at least about 5' onto spring board. I should be able to launch at least 7.5 feet. what you have forgotten, is the height that the person can physically jump onto the spring board.
It just came to see why the whales stopped talking. Thankfully it was not screaming at our oceans in the process. Finding that the living whales were no longer using radio, it just moved on. ;)
If Oumuamua was weighted on one end and it was spinning, wouldn't this considerably affect its velocity when this motion dynamic interacted with the sun's gravity leading to our observing it speeding up as it passed the sun?
Starting at @33:40, pausing at 34:05 & starting up again at 35:00, the question that Chuck asked about an object, such as a comet, coming into the atmosphere that breaks up & sprinkles its particles down onto the surface of the Earth & Neil's description that the kinetic energy of the object hitting the atmosphere & breaking up, or hitting the atmosphere and hitting the surface of the Earth, that energy has to go somewhere. So, wouldn't that be a perfect description of 'the Tunguska Incident', where, in June of 1908, an object, probably a comet, entered the Earth's atmosphere over Asia and, perhaps 2 kilometers above the ground, exploded??
It was an alien ship, it checked on the whales and then it sodded off :-) If it's natural, I'm guessing a basalt pillar from a smashed up planetesimal . Like one of those from the giants causeway in Ireland but bigger.
its fun when Neil and Chuck riff off one another when its just them and theyre joking and having fun with fan questions or topics that have been talked about to death but when theres a guest there to talk seriously about a topic it becomes very frustrating to listen to because the conversation seems to be all over the map, i never know which mode to switch my brain to.

Also this would cause a slight deceleration as it arrives in the inner solar system, as the dark side of Oumuamua consistently would not experience such an accelerative phenomenon.
Right! It's movements were "wobbly" and and unpredictable or should I say unexpected by many I'm sure when radiowaves were sent to try to make light (pun intended) of it. I wonder if it's evaporated water or ice but still maintains all the energy it has absorbed over time...maybe it's a proverbial garbage can.
@@sarahalhassen2902 yeah possibly! That is roughly how solar sail tech would work. Its oblong shape is probably the weirdest thing about Oumamoua. It seems like something that size and that thin would be torn apart by orbit unless somehow it's being artificially held together by engineering...
Yo what, I was just talking about this with a coworker earlier today, this upload is eerie timing, and I like that
same, I have been catching up on what Avi Loeb has been saying this week
Forreal i listened about it from the lex fridman podcasts yesterday then it popped up on startalk
Same dude
Same here, it's that sweet science bubble I think.
@ Nick Dahlstrom Same I was just talking to a buddy of mine about this
Love the series. Dr Natalie was wonderful with her insights. 👍🏻
The alien spaceship hypothesis reminds me of a short story by Polish SF writer Stanisław Lem (for those who don't know: the author of "Solaris" book, later put to screen by Soderbergh). It was translated into English and published in a book titled "More Tales of Pirx the Pilot", the story itself titled "Pirx's Tale". I highly recommend it if you could get hold of it - the book was published in 1983. Lem's kinda famous about things that he wrote about as a fantasy or a potential future technology that eventually came to pass in one way or another (such as virtual reality). The moment I heard about Omuamua and a possibility (even if very remote) of it being an alien spaceship I thought: "Lem predicted that - again!". The Lem's story basically tells how easy we could miss an evidence of an alien civilization, if any such exists or existed, by pure bad luck.
lem is awesome

Love her English accent. 😍
She's got a great smile 😁
Our favorite Astrophysicist in da house bois!
I'm confused by the British lady she said that it was going so fast that it was never going to be pulled in by our sun but she also says it had an orbit
Joe Rogan and Avi Loeb brought me here. Anyone else in the same boat ? 😊
QUESTION: Is there any chance that one reason Oumuamua accelerated at some point after passing the Sun is because only the side facing back toward the Sun (at any point in time) would be the side being exposed directly to its radiation and therefore the side "ejecting" (either through sublimation or evaporation) material. If the object was light weight, it wouldn't take much to accelerate it. However, this would also mean it might've decelerated on approach but not as much (due to be larger in its approach).
I am watching this with dark fantasy music plying in the background. This whole session feels epic.
Noice.
It's vastly more likely that this is one of many millions of interstellar objects that have come by the inner solar system in recent geologic time, than it being the first.
It's just me or ladies talking that deep science are just beautiful?
The kind of beauty you're talking about comes from the brain, not the skin.
contact the sharknado people, i'm sure astrocano can be made!
This concept just blew me
Some changes are slow, some can be quite fast. Cliffs can tumble overnight. A storm can change the shape of a beach. An earthquake can leave lasting changes.
44:20 I feel like because it was in interstellar space and had no strong acting on it it must have been cut off a larger body by a super fast moving object that didn't do much damage when it cut through the larger body. Since it may not have had time to reshape itself it probably just shot through our Galaxy as a new formed shard of something
I get way too excited about Cosmic Queries 😂
As do I especially when anyone mentions the lovell
No such thing lol Space is freakin cool.
Theoretical concepts and new perceptions of Astro-physics especially excite me. I also am really intrigued by new discoveries made by human and machine!
maybe they need to listen to avi loeb
That guy is really smart. Understatement. Great guy.
They might after this video! Haha look at the comments its half about avi lol theyd be silly not to. Only thing i could see stopping them is the side that would criticize him. Hopefully theyre bigger then that but if not i still love them ( I know theres other people who have to accept it im sure)
@@DavidRice541
The problem with worrying about the people that would potentially criticize them for having Avi on is that those are the same scientists that Avi is pointing a spotlight on that have turned their scientific methodology into a kind of dogmatism.
They brought her on because Neil and her are prob the colleague they shun and bash Avi Loeb.

PLease answer my query, is there any chance we can piggy back on such interstellar objects which will carry us to different solar systems/galaxies..?
If you're here for the alien possiblity it's at 39:16.....they call it a comet the whole time even tho several things about it are incredibly weird.
Maybe they should’ve just brought avi loeb on the show!
Watch joe rogan or lex firdmans podcast w avi loeb
Get Avi Loeb in here, he will tell you and try to convince you it's alien ship.
And a book to sell you...
Or maybe he was frustrated with his own people neglecting to be open minded and to fail which would further result in him needing a platform to burst out his anger that he kept with himself for his whole life ?
@@g0ddyie "with his own people " And by this, you or course meant the other scientist is his Lab or was it the other supporters of his favorite team?
@@Wtiberon Why don't you write a book and try to sell it and we'll see how many podcasts you're called upon.
He's a reputed scientist and wants to convey a very important message regarding the shyness of these scientists on stuff related to the unusual appearance of cosmic bodies and people like you instead of supporting him questioning his character? Shame on you
@@akashbhullar You think that is how it works? Someone writes a book, and a bunch of podcasts are instantly notified by....magic? OR do you think he hired a publicist who called each and every podcast weeks or months ago to advertise his book to gullible people? Clearly, you aren't capable of critical thinking, and appealing to his status as a scientist adds no credibility to his motivations. Shame on you.
THAT IS SO WEIRD IVE BEEN HOPING THEY WOULD DO THIS ALL WEEK
Always a pleasure to learn incredible facts about our universe and Chuck, I think you provide an earthy ' bad pun' humor that keeps me laughing and interested. I'd enjoy seeing you on stage. Good 👍 luck in your career 👍
Chuck's face when his jokes dont hit are hilarious too.
Haha his jokes never hit and i only listen
Chuck is funny, imo
is there some planets with a gold core insted of a iron core, or a mix of iron and gold? or iron around gold core?
There’s a planet that has a diamond core that rains glass sideways ..
@@ojayojay4015 its cool with diamond core.. thats soo cool..just wanted to know if the is such thig as a gold core insted of just iron core..
i'm no geologist or physicist, but i see no reason why there wasn't a LOT of gold (and other heavy metals) at the core of the Earth. At those pressures and temperatures, the single differentiating factor that would separate elements is their density afaik. We have trouble finding gold exactly because of that, most of it has already sunken below, far beyond our wildest hopes of reaching.
Tx for the answere. I didnt know that maybee we have a golden core after all🙂

19:48 That question is the most often asked about all kinds of events, which have only been witnessed once. The answer is: "We don't know. We can't know, not until we see at least one more. One measurement is no measurement!"
new year's resolution - listen to everything that comes up on StarTalk channel
What would next years resolution be? To understand everything that is said on startalk channel?
I've been here for a while.. but i have to say.. i love this show.
Who else has already listened to the podcast of this but are rewatching so you see the convo with faces lol
Oh, so that's why i have the feeling like, I've listened to this before 🤣
If i remember correctly, the audio only version of this already been posted on the "Neil deGrasse Tyson Office" channel...?
Or Spotify maybe, I don't use Spotify.
Does the radiation in space cause objects to slow down similar to drag or friction and thus could Oumuamua slow down, in its trajectory and/or its spin/rotation and how long would it take?
Hey Neil.....I really loved cosmos ...♥️♥️best series
A question to Nathalie :
If the most dense metals sinck to the core , would GOLD not accumulate in the middle ?
Or radioactive metals ?
Was a great video /stream , well done Sir's ☆☆

Studying space rocks is cool af. Love from interstellar space.❤️👍🏻👽
Im still surprised when an episode pops up that I haven't seen before
Umm, are we not gonna talk about Oumuamua accelerating faster than it's presumed composition can explain? Must likely from solar winds.
Something we've never seen naturally occurring rocks in our system do, something comets can only do if they exhaust and lose some of their composite particles which is evident by observing their loss of mass as well as the exhaust.
That said, it is a behavior and acceleration we have seen man made space junk do?
Seems odd we also omitted that it is incredibly shiny compared to most naturally occurring rocks in our system.
Seems like a pretty huge details to omit when talking about it.
Seems odd to dismiss the best fit examples we have, artificially man made junk can and does behave like this object, and that junk we've made can and does share unusually reflective properties.
The 'naturally occurring' claim seems far more of 'requiring extraordinary evidence' when we mention everything we do know about it.
The claim a thing shaped like nothing we've ever seen naturally occurring in our solar system or outside of it, that moves only like space junk we have made, is not interstellar space junk but is instead a naturally occurring never before seen shape, moving in a way we've never seen anything naturally occurring move that wasn't a comet that sheds mass when moving as such, unlike this object, reflects light in a way we have only seen our own space junk reflect... We must first prove it's not naturally occurring??
I'm sorry but if it looks like a duck and quacks like a duck and is shaped like a duck and moves like a duck and reflects light like a duck, why are we taking the Catholic Church inquisition model of 'it must be a zebra unless proven otherwise' position?
If what we know for sure points most firmly at, 'there's a chance this is space junk from somewhere else,' I'm not clear why that cannot be equally plausible and ought not be given at least equal time as far as studying it.
We already know a myriad of reasons, like distance and the passage of time to cover those distances, means we may never 2 way interact with another species from another system. However, it is plausible given the insane amount of space junk we've made in just a few decades that the likelihood of space junk flying in every direction from every system that once had space faring civilization is plausible at least.
That's like a species that eventually gets intercepted by voyager saying, OBVIOUSLY we have to rule out naturally occurring because no way can intelligent life ever happen in another system.
The moment we put stuff in space opens the possibility other life forms did the same at some point somewhere else. It is absurd that any human could immediately dismiss the possiblity this is something else's garbage, when the one thing we know for a fact is long after we destroy ourselves, our garbage will be around for much much longer. And the garage we have littered all over space will be around several orders of magnitude longer than that earth moon and Mars junk.
one theory i read about the shape of Oumuamua, was that it was created during title forces when passing a star in hot (kind of melting) conditions.. how possible is this?
Abraham Loeb interview, When? would be an interesting debate, since he is a respected academic.
Chuck is so hilarious mann.. Love ur show Neil n waiting for a new podcast..
Would like to hear her comment on how it was measured to be appropriately at the local standard or rest for our galaxy.
I love when Neil gets excited lol
We actually see the "rocks being light and floating" phenomenon in agriculture, where even though we remove rocks from a field, the neck year more rocks has come up to the surface. Atleast here in Denmark we call it "Moving Rocks"
That's freezing action on water in the soil, though. It basically only takes place because we till the soil; the effect doesn't bring rocks up from deeper than a couple of meters under the plough's cutting depth, and it's not happening where there's never a freezing winter ;)
you move the rocks. the dirt under them blows away, exposing the next layer, cmon dnt be dumb
If the object has the appropriate elements, could the collision itself provide a cauldron that results in the possible creation of building block molecules from those elements? I seem to remember an experiment that tried to reproduce such an impact and they did find building block molecules in the aftermath -- not sure at all about how well the experiment was designed and executed though.
Sitting here really picturing a floating volcano hurling through space...🤦♂️ thanks chuck...😂
Imagine floating space pimple periodically exploding hahahaha

I feel like the villain from the fifth element is a rogue volcanic planet.
It is just me or the similarities with the object from Arthur C Clark's "Rendezvous with Rama" is amazing,
That was many people's first thought back in 2017 :-)
MANY writers have been prescient about MANY things. Clark was also very prescient about geostationary satellites, three as a minimum, being used for radio transmission around the globe. There were not even rockets capable of injecting satellites into such an orbit at the time. SO MUCH technology had to be created before that actually happened. And Clark was a surprised as anyone when his idea was actually realized. And read Jules Verne's stuff too. His ideas of technology are not that close but WHAT might be done, and actually has been accomplished, is very close!

Is it not the case that a passing interstellar object/comet that grazes our atmosphere may exchange material with us without hitting us?can't remember the term I heard now.
When I saw the title, I thought you guys were interviewing Prof. Abraham Loeb
2I/Borisov was an "ordinary, dusty-iceball"-comet from an unknown star-system. 1I/'Oumuamua was rare and special. I can't conceive, that Daryl Seligman's new hypothesis of an H2-iceball (Hydrogen-iceball) fits in Oumuamua's case. Although it could explain the unknown acceleration, it should have been evaporated at its sun-passage! Oumuamua was of "rocky"-material or even of metallic-composition, nickel-iron probably, so it had no problem sustaining the sun's heat. Please read Roman R. Raficov's paper 1I/'Oumuamua-like Interstellar Asteroids as possible Messengers from Dead Stars ... white dwarf-stars... in " The Astrophysical Journal "
2018 ApJ 861 35 . if a hot metallic core of a planetoid gets torn apart within the Roché-radius of a white-dwarf-star, this elongated shape of Oumuamua can easily be explained!
Argh I'm getting the itch to go back to uni 😫
Please do it!
@@KushClarkKent 🤣 waiting to hear if I got into a post graduate diploma
i wonder if the velocity of omuamua was exacly the scape velocity of our solar system, if it was before we detected that it boost a little bit, or after the boost,,or was way higher even without the boost...
I could listen to StarTalk all day .. Especially the cosmic queries editions 🎧🌌😎🙌
Felt like it was just 10 minutes, time flies so fast listening to scientists
time is relative 🤌🏿
listening to Avi Loeb it seems that all the natural explanations are already ruled out
Those ruled out are only the natural explanations that are known so far. There might be other explanations that could explain it that hadn't been discovered yet, and that explanation could be natural and yes it could be artificial.
@@hechanova07 What he is saying is that these people are repeating debunked information given the new information thats out there. So they have to move the conversation forward and theorize what other phenomenon it could be.
@@jramir2 Yes I agree with what you're saying.
@@jramir2 exactly, i was sure they would dig a bit into that subject in 45 mins, but they managed to ignore it the whole time. I am a big fan of NdT but this episode left me very disappointed and i cant imagine the frustration Avi Loeb feels having to go through this every day
@@ihaveguts I agree with you, what makes me even more mad is that they not only rule out the alien hypothesis, they make fun of basically everyone who dares to even consider it, I'd hope scientists were open minded people who consider any possibility until proven wrong.
Dr. Tyson,
Can we use these objects that travel so fast in space and model our spacecrafts based off their movements? They’re not using fuel and they’re faster than we we can.
Thought you might have had Avi on....?
Hi: In 1975, I figure skated. I also weight lifted to obtain strength. I could squat (with a 2x4 under my heels to match the heel height of my skates). I could do 500 lb squats (one set of 6, sit on a bench, then stand up). If the packs in NASA weighed 200 lbs on earth, it would weigh only about 33 lbs. I weighed 185 lbs then. My foot weight with the 500 lbs would be 685 lbs. If I went to jump on a spring board, it would not happen (not enough physical strength to jump). On earth, I could jump 4 feet onto a spring board to go up about 6 feet. On the moon, the 500 lbs + my 185 lbs would only be 114 lbs. This should mean that I could jump at least about 5' onto spring board. I should be able to launch at least 7.5 feet. what you have forgotten, is the height that the person can physically jump onto the spring board.
What if we witnessed another systems version of voyager?
It just came to see why the whales stopped talking. Thankfully it was not screaming at our oceans in the process. Finding that the living whales were no longer using radio, it just moved on. ;)
If Oumuamua was weighted on one end and it was spinning, wouldn't this considerably affect its velocity when this motion dynamic interacted with the sun's gravity leading to our observing it speeding up as it passed the sun?
finally...i waited you talk about it
Starting at @33:40, pausing at 34:05 & starting up again at 35:00, the question that Chuck asked about an object, such as a comet, coming into the atmosphere that breaks up & sprinkles its particles down onto the surface of the Earth & Neil's description that the kinetic energy of the object hitting the atmosphere & breaking up, or hitting the atmosphere and hitting the surface of the Earth, that energy has to go somewhere. So, wouldn't that be a perfect description of 'the Tunguska Incident', where, in June of 1908, an object, probably a comet, entered the Earth's atmosphere over Asia and, perhaps 2 kilometers above the ground, exploded??
It was an alien ship, it checked on the whales and then it sodded off :-)
If it's natural, I'm guessing a basalt pillar from a smashed up planetesimal . Like one of those from the giants causeway in Ireland but bigger.
wow we have a youtube expert here no way
I find myself listening less to other podcast and more to StarTalk. Probably my favorite podcast.
