Astrophysicists Discuss Our First Encounters with Interstellar Objects

[@StarTalk]

If 'Oumuamua traveled from another star system, could its strange acceleration be evidence of unknown forces at play in interstellar space, or even hint at advanced technology from elsewhere in the universe?

[@michaelccopelandsr7120]

Yes

[@michaelccopelandsr7120]

Remember when Bugs Bunny threw the baseball around the world and it came back plastered with tourist stickers? We need to plaster 'Oumuamua with them. "3rd Rock from the Sun" "Terrans were here" "Earth girls are fun" "Traveled 184,000 lightyears to Earth and all I got was this lousy bumper sticker"

[@melkorred6784]

Until we can easily defend the space around Earth, we don't want anything outside of what we can see to know we are here.

[@dahighlander2468]

It feels like the expansion of the universe could cause the strange acceleration. If it came from a distant solar system, and the distance between that system and ours expanded, wouldn't that just raise the gravitational potential energy, and when it falls into the suns pull, it's kinetic energy would be higher than when it was originally launched. Idk, I just have a communication degree

Please feel free to make the episodes longer. I'm sure many of us wouldn't mind watching a 2hr episode. We Love the show♥️

[@josepht5331]

I get the idea but 2+ hour videos in YT don’t typically do well in the YT algorithm (unless they are meditation/sound therapy videos). Mostly because people don’t have the attention span to watch a two hour videos on a phone or tablet (which is still how most watch YT) without distractions. As a person with 4 kids I love the explainers and 1 hour videos because if every episode was 2 hours it would be hard to watch it all the way through in one swoop. Leaving unfinished episodes. I understand this isn’t everyone’s situations but as a former creator I do know YT doesn’t recommend long episodes in most channels. I’m sure that is part of the reason they don’t do it.

❤I really appreciate when Neil interrupts his guest and I rarely have a problem with him slowing them down to elaborate deeper. It shows a great deal of humility on his part, that in all these years he still realizes many in his field suffers from expert blindness, as they're no longer able to see others that may not understand certain terms, theories or project purposes on their same level. Not being able to truly follow a discussion makes one lose focus. While researching and reading new information is always a fun exploration and pass time, no one wants to google every 60 minute StarTalk from beginning to end. Some channels do forget this small step of remembering their followers. I research to pull things apart naturally and it is the reason I'll have like 100 tabs open on any given day regardless. 😆 But its his thoughtfulness that matters.

[@adamc7591]

This is why NDT is a science communicator and a near master one at that.

[@dumaskhan]

Also, most experts forget that people watching them have no idea what they are talking about unless you break it down. It is the role of the host to ensure that complex terms are broken down, if not for the conversation then for the sake of the viewer without advanced knowledge.

That science does not make declaritive statements such as "This is how it is" or "Because I said so", and you are forced to take it on faith that it is True. Science provides an ever-changing and constantly refined model of the mechanics behind the functions of our very existence. What was once described as 'magic' or 'The Unknowable Hand of Mighty God' becomes a simple formula that anyone with an open mind can see the merit of.. The calm voice of sanity in an inreasing ocean of self-serving religious dogma and new-age nonsense. Thank you.

For ‘Oumuamua, see the paper “1I/‘Oumuamua as debris of dwarf interstellar comet that disintegrated before perihelion”, by Zdenek Sekanina; arXiv 1901.08704, 31 January 2019. Since it appears only on the preprint server, this has never been peer reviewed. Sekanina is now retired from the Jet Propulsion Laboratory, where he was a well known cometary scientist. Sekanina points out that ‘Oumuamua was discovered well after perihelion, so the assumption that the object we see is the whole object that came into the solar system originally, might not be correct. It could be a fragment. And if so, it could be much more porous & much less dense, and in that case, radiation pressure alone will explain the nongravitational acceleration. This is consistent with the observation that nearly all long-period Oort Cloud comets, in our own solar system disintegrate, if they experience perihelion passage as close as that calculated for ‘Oumuamua, while nearly all short period comets do not. So the observed behavior of ‘Oumuamua is consistent with ‘Oumuamua being a fragment of an interstellar comet that is similar in nature than Oort Cloud comet in our own solar system. See the paper for all the detailed arguments & data analysis. It is also consistent with the failure of the Spitzer Space Telescope to detect jets of either CO or CO2. This is the explanation I prefer. See the paper here: ui.adsabs.harvard.edu/abs/2019arXiv190108704S/abstract

What interesting about Oumuamua is, the solar system gravitational pull wasn't strong enough to keep it locked into our solar system, but our solar system keeps all planets locked millions of miles away. I guess since it was traveling at a faster speed is why it was able to escape the solar systems gravitational pull. It would have been cool if we could have sent a satellite 🛰️ towards the asteroid to monitor it and see where it was headed in space.

[@Sammasambuddha]

Realizing your fantasy *is* terrifying, I believe the terror is misdirected. *If* any object was moving (relative to earth) at 35% the SoL, it would be going 235Million mph / 376Million kph. That speed would be improbable unless a hyper dense object like a black hole was involved. Even if an object was moving at 1% the SoL, that equates to 6.7Million mph. Also improbable. Oumuamua was recorded at 195,000 mph. The terror of an object moving in the millions of mph is that anything it hit would be instantly obliterated, like any planet. Like a .50 cal hitting a watermelon. Terrifying. Most meteors are going in the tens of thousands...but the one that killed off the dinos was going about 144,000mph.

If some three body problem between two black holes and this mass ejected the mass it could do so at riddiculous speed. Most of the mass would get eaten but some would fly out randomly. So tiny chunks flying outward like a shotgun. They are tiny enough to generally not interact with anything in big empty interstellar or intergalactic space. But a chance direct hit could destroy a planetoid. At that speed and size noticing it would be hard. It would just be blind luck an hoping you are never in the wrong place when one zooms through. Even if there were a hundred in our solar system at a time they wouldn't gravitational affect anything enough to be noticed.

If you saw Haley's when you were young you most definitely could see it again, just saying. To see it at 152 years you would have to have seen it at 76 years old.

How wonderful it must be to be so engrossed in your field of study that you get excited just to talk about it AND you get paid to learn as much as you can about it. On the other hand, every question you answer you now have 10 more. My question now is "do comets ever run out of ice and become asteroids"?

[@Times_Ticking]

Laugh all you want. But when one of those interstellar objects starts transmitting, Chuck's gonna be, "I told you so!" :) Have fun guys!

For Oumuamua, it will always be a hypothesis, can't do any testing on it, to confirm anything, no return route. Best is conjecture/comparison.

[@Looshington]

I would HATE to be any sort of astrophycisist being interviewed by neil, man😅

[@tomirwinbernier-ll2hm]

I wouldn’t be intimidated talking to Mr Tyson (Neil that is, Mike scares the blood from my face), as he doesn’t ever talk down to people. He usually takes the time to explain things he feels the average person likely doesn’t know. For someone so intelligent, he isn’t arrogant, which is quite rare. He truly is one of the few that can pull off being truly intellectually gifted, and act Normally when interacting with others…

Time for a bigger coat Neil, that looks like a smedium...

[@ShowMeTheMoneyShot]

It’s just a faze

Excellent job y'all, learned a lot of things that I hadn't known on this one.. I think chuck did as well, he wasn't clowning as much as usual.

Chuck asks great questions!

[@MahmoudMaguid]

A great well spoken guest. Thank you for sharing your passion with us.

[@よしとん-z6p]

Such an exciting topic for me, interstellar objects! I enjoyed listening to the guest! My imagination is now flying everywhere with excitement :)

[@Supermanohman]

Chuck thinks like most of us think, at least how I think. That's why he's so important

[@mickeybrumfield764]

Looking forward to hearing more about dark comets in our galaxy and universe and maybe getting deeper insights into how prevalent they are and what they consist of.

[@FairDealDan]

If no one has said it yet I'll say it... time-stamps really help! THANKS
