Impact Hypothesis

[00:06] Oh, we doing under Google rules that was the player super excited told us we had to
[00:17] say we said we signed up for it in the end it's gonna be better and more true
[00:25] than Google can give you questions from the listeners where'd all the water come
[00:34] from question is where's like a water come from is this like from somebody you
[00:43] know in a basement or like an apartment building because I'd say you need to
[00:49] contact your upstairs neighbor but yeah no where do all the water come from I
[00:54] think I think it's a more general question not specifically towards Michigan but
[00:59] probably towards the in the earth and this is what okay so right okay I imagine
[01:10] this stems from you know one of the things that we do when we search the
[01:16] outer atmosphere is to try to find planets with water on right cuz it seems
[01:20] like a rare thing yeah and earth is 70% water why does why have so much water
[01:25] does that happen I think in the past it was less oh well used to be ice yeah at
[01:38] some point is zero man I so I think I mean I you know the I believe my
[01:45] understanding of this is that you know as the as the planet formed you know all
[01:54] the contents were there you know that are you know when it when the planet was
[01:59] formed all the all the elements and whatnot I believe a lot of it it came
[02:07] from like volcanic eruptions you know while the planet was cooling you know as
[02:14] it you know the magma was coming up it was you know released in the air as as
[02:24] their volcanic eruptions yeah so in fact I was just listening to a stuff you should
[02:29] know on how fire works and yeah I literally just listen to that same one
[02:35] yeah it was just just a recap one yeah and water is a byproduct of combustion
[02:42] what someone could imagine as magma is spewing out and burning whatever carbon
[02:50] stuff is there one of the byproducts is water and that might build up over time
[02:55] or something as you continue that's definitely important carbon okay but
[03:00] atmosphere also definitely very important that's Mike that's my whole
[03:04] theory right so the you you've got all this stuff trapped and it's moving as
[03:10] vapor right but it's trapped in the atmosphere it can't leave and so then it
[03:16] it train changes forms yeah from gas to solid and then atmosphere is definitely
[03:25] key like I don't know I like this is probably a whole other under Google but
[03:30] like creating enough gas to create an atmosphere probably took a long time
[03:41] yeah I know I mean before we had tectonic movement volcanoes we definitely had a
[03:47] bunch of like comments and meteors and stuff right and I know they brought a
[03:51] lot of useful stuff right I'll assume that water is part of that like on
[03:56] some level once you have an atmosphere you've got hydrogen and oxygen at that
[04:01] point you get lightning and that'll make some water for you right like yep
[04:07] why does lightning make water it just uses stuff you're saying like h2o it
[04:17] literally well my dad told me a story about he went to a like science museum
[04:21] when he was a kid and like they put hydrogen and hydrogen into thing and
[04:27] like shot in a bunch of lectures like I don't think you can do this anymore
[04:31] because it sounds like a nuclear reaction gone bad but like no they
[04:35] literally like made some water I think mm-hmm it's a bad idea like that's an
[04:41] explosive reaction but like in the wild it's a thing that happens right sure
[04:48] yeah I think also um yeah it's got to be you know it's all chemistry I guess
[04:55] right it's whatever constituent elements you have and the different chemical
[04:59] reactions that go on right so once you have atmosphere you're heating and
[05:03] cooling and that's causing condensation of water out of the atmosphere or
[05:09] different reaction by which the bite one of the byproducts water right and
[05:15] presumably those were just more favorable on on the earth than than in
[05:22] other places I mean they have found evidence of water on other planets right
[05:27] oh for a hundred percent yeah and so I think that yeah I don't know yeah
[05:33] definitely like wasn't isn't the moon one theory that the moon is like a chunk of
[05:39] the earth they got like knocked off when it yeah by a meteor or something
[05:43] like that yeah yeah yeah for sure I can definitely tell you that Mars is
[05:49] supposed to be bigger hmm supposed to be supposed to be what bigger what it
[05:56] got destroyed by something it's something well just look at the like
[05:59] progression of the solar system right mm-hmm smaller larger larger smaller
[06:06] hmm way larger hmm I got this but no I mean so maybe the question that we
[06:17] really need to be asking is winded like once you have atmosphere lots of things
[06:23] are possible there's traces of this stuff on Mars which has almost no
[06:28] atmosphere so we can assume that it gets there one way or another right so
[06:35] comets meteorites whatever else on earth we're in the Goldilocks zone mm-hmm we
[06:44] managed to form an atmosphere and we trapped just a lot more in and then it
[06:48] becomes additive it comes an additive process right then you get weather then
[06:53] you get lightning then you get you know what have you and then you have a whole
[06:59] cycle then you get a cycle right evaporates pepper awesome we're counting
[07:03] on you we're counting on you to Google this oh you're a science guy where did
[07:08] all the water come from what I'm asking yeah you're our science correspondent
[07:17] this is day job you know hey we don't want it we don't want to make Jason do
[07:22] more science and is off time that's just right that's true that's true okay
[07:28] the first thing that comes up when you type in where did all the water come
[07:31] from is much of the earth's water is thought to have come from asteroids
[07:35] impacting the planet early in its history the surface of the very young
[07:40] earth was initially an ocean of magma hydrogen and noble gases from the solar
[07:46] you're just gonna read me Wikipedia yeah will you say magma correctly please
[07:50] magma magma planetary embryo just I don't like that one yeah it seems like we're
[08:13] kind of on board is that that that hydrogen would easily escape earth's
[08:21] gravitational pull except we had a atmosphere and when the earth was smaller
[08:29] and less massive shit that's not helping today so I'm just running across this
[08:42] yeah it's like that footnote of a wiki the University of Munster moon stir and
[08:50] from 29th from 2019 shows that believed in them isotope composition of the
[08:57] earth's core originates from the outer solar system mmm likely having brought
[09:02] water earth so this basically is a collision theory yeah and the giant
[09:07] impact hypothesis is about 4.5 billion years ago forming the moon and may have
[09:15] also originated the outer solar system rather the inner solar system bringing
[09:19] water and carbon-based materials with it and that's like like I said that's a
[09:26] pretty new theory okay yeah so a peer-reviewed paper published in the
[09:31] journal of geophysical research planets on in 2018 suggests that the the earth's
[09:42] ocean water is similar to that found in asteroids and then that most of
[09:47] earthly water came from an asteroid bombardment in the days of the early solar
[09:51] system the ratio of deuterium a heavier hydrogen isotope deuterium to normal
[10:00] hydrogen as unique chemical signature in various water sources the deuterium to
[10:07] hydrogen ratio is close to what is found in asteroids yeah these are not well
[10:21] yeah the atmosphere is important none of these analyses are super fulfilling
[10:26] which is why even on wiki there's one from last year that has like real legs on
[10:32] it the I think it comes down to we don't we don't know for sure huh
[10:37] because between you have to have all the gases to make the atmosphere but you
[10:48] need all the things in the atmosphere to make the water right so it's we
[10:53] don't quite understand how this happened yet is that fair from what you're reading
[10:57] J J T yeah seems like it's a lot of you know a lot of collision stuff a lot of
[11:05] collision stuff of things so there's evidence that to 4.5 billion year old
[11:10] meteorites have been found on earth that contain liquid water alongside a wide
[11:16] diversity of deuterium let me stop you're right there compounds let me stop
[11:20] you're right there you found two two point five billion old meters just on
[11:26] earth you did that yeah somebody that's I mean that's pretty rad that we could
[11:38] even figure that out yeah is this this Chan et al and science advances and then
[11:44] there is this giant impact hypothesis which is that a thing called thea or
[11:51] thea was a hypothesized ancient planet in the solar system that collided with
[11:58] the earth around also around 4.5 billion years ago it was about the size
[12:02] of Mars and it hit the earth and that's where the moon gave gave the gave
[12:09] race to the moon as well but it also carried with it a ton of water okay so
[12:15] for the purpose of consensus and then as as the earth is gaining in size you're
[12:20] having more gravity and you're able to keep those gases from escaping off into
[12:24] outer atmosphere so for the purposes of consensus here we can agree that there's
[12:29] a bunch of extra earth right collisions that happen yeah and whether those are a
[12:36] large earth with smaller collisions or smaller earth with larger collisions and
[12:41] if the moon's like we're not sure exactly how that goes down but basically this
[12:47] shit comes from outer space right right so which reminds me of another stuff
[12:52] you should know episode are we all Martians which talks about this idea
[12:56] that you know water and maybe the building blocks of life were brought by
[13:02] some of these other impacts into the planet or something well we're all space
[13:05] dust so nothing matters well sure you know if you want to go back that far sure
[13:09] yeah we all came from Sun's so I have a stupid question so good cuz I got a
[13:18] really dumb answer so we're talking about all these these impacts are they
[13:25] they're just they're they're bringing the important elements from outer space
[13:29] is it the actual impacts that's creating this combustion you guys were
[13:32] talking about earlier or they just bring in like just straight-ass water I think
[13:38] it's they're bringing straight-ass water you saying so is this is like you
[13:42] think like pure ass water is that yeah because I mean cuz I keep reading they
[13:47] didn't bring a bidet per se but one of the things I was reading was saying
[13:52] without the atmosphere we were getting you know pummeled with stuff and it
[13:55] was just going back out into space and then once you create an atmosphere then
[13:58] this stuff can get trapped but yeah are they actually just straight bringing
[14:03] water or are they just bringing the elements that we try yes is what I'm
[14:06] saying okay so simple simple thing like everybody knows Haley's comment right
[14:10] mm-hmm it's got a bunch of ice in it right it's coming mm-hmm here's the
[14:17] tricky part ice is water yeah hmm so if it melts on earth then it just
[14:22] becomes water okay got it yeah just lives here now and like presumably
[14:26] something is lost in that translation especially with how hard the earth how
[14:30] hot the earth was at that time but again it's about putting the elements in the
[14:35] same place eventually you know getting those things creates atmosphere right and
[14:41] then from there as long as it doesn't burn off too quickly or freeze right you end up
[14:46] with water yeah you just kind of do well there you go that's where the
[14:52] water came from when I mean there couldn't be I guess it like water water
[14:57] there couldn't be liquid water until the earth cooled enough you know when it
[15:02] was forming it was still you know too hot for that it's still state gas but you
[15:07] got to have the earth's got to be cool enough and you got to have an atmosphere
[15:11] to keep up keep all that to yourself no I'm kind of thinking of these
[15:14] comments like holding like inflatable pools you know just straight like water
[15:19] you know just and then just kind of dump it on the earth so I was thinking
[15:25] here's what I'm thinking yeah that's how it cooled right just play pool just like
[15:31] a slip and slide really little steam action Coalson I'm thinking that you know
[15:38] we've been doing this show and the under Google Bulls for some time now I think
[15:42] the next evolution is an animated version of this yeah yeah yeah slip inside
[15:50] theory of water deposition on earth quantum physics really I mean we're on
[15:57] the verge of a breakthrough here guys I published this is Coalson get after it
[16:02] peer-reviewed by you three you got to find some sympathetic pierce yeah all
[16:11] right well I think we nailed that yeah yeah yeah I think we proved where water
[16:19] came from in the same episode callback it'll make it harder to split up into
[16:28] too many episodes for the under Google Bulls it won't make as much sense but it'll
[16:33] be fine it's nice little Easter egg yeah for the true fans all right well I
[16:42] think that I think that wraps it up unless you guys have any more knowledge
[16:46] to drop on us I just want to say that all fans are true fans mm-hmm yes you
[16:51] got all suck it I do this for neat me and not for you like to thank you for
[16:56] hanging out with us if you'd like to give hey that was too on brand live with
[17:02] you want to give us your opinions on how you feel about us you can do so on
