What would happen if we had another Earth as a binary companion? Will the moon become the new ISS? Will humanity ever try panspermia? Any Q&A plus? How to apply your coding skills for astronomy? All this and more in this question show. It's time for the question show your questions. My answers as always wherever you are across my channel if a question pops to your brain just write it down We'll gather them up and I will answer them here. All right, let's get into the questions Dan Chepi if the moon was like a second Earth would our space technology be way more advanced at this point? Yeah, absolutely So if Earth was a binary planetary system and you had two Earths that were orbiting around a common center of gravity and They were going around the Sun and they were identical. They were the same size same mass same gravity Same atmospheric composition, which would be tricky because you know our atmospheric composition comes from life Then and if there was life there and life had maybe been spreading back and forth panspermia in from Earth to other Earth and back and forth Then we and and only say an intelligent civilization only humanity had evolved here on planet Earth Then we would absolutely be going there on a regular basis because it would support human habitation And the best example of this is like back in the age of exploration You know think about in the times the 1400s 1500s people were sailing around the world you had Magellan They were going to these various places around the world on a little boat And if they needed more food they they fished or they stopped at a At a forest and they picked a bunch of stuff or they stopped at a at a village and they purchased food Or stole it. Um, if they need water it rained on top of them. They needed to breathe. They just breathed Right if they needed more trees to repair the ship they could stop and get all the stuff They needed so all of the supplies that they required were just there and available We won't have any of that in spaceflight Now there might be you know later on our technology will allow us to pull in the resources that we require from some other World whether we're gonna use Regulates for building material or whatever But really every place that we're gonna want to go in the solar system is the worst parts of Antarctica times a thousand And we're gonna have to live there But if there was this other earth right over there vegetation Maybe shared a common ancestor and we could get there and then once you're there then you can cut down trees and drink the water and You know it is and introduce earth's animals Then we would turn this into the other earth and then there would be Trade back and forth or at the very least there would be people commuting back and forth from these two planets Once you had a foothold so it just comes down to are the places that you're going? Habitable which they are not in the solar system if they are habitable then you can Then you have a tow hold then you can Continue on and grow a civilization out of almost nothing. That's a this is a thing that human beings are very good at But we need to be able to just breathe Drink water find food Mine metals these are the things we need to be able to do and right now all Space exploration is gonna require us doing that stuff the hard way Maybe would there ever be a point where humans decide to try to pantsper me on Mars? I mean you could say that we've already tried a pantsper me on Mars every time we send spacecraft to Mars They're covered in earth bacteria and so We know that there are various forms of earth bacteria They know they're hardy enough to withstand the process designed to kill them to get them off the spacecraft Now they radiate them to heat them they cool them they expose them to vacuum and yet they then travel through space for a year land on Mars and they're still alive and Theoretically if they find the kinds of conditions that would make them happy they could restart and keep growing So we've already done this there there are microbes from earth that are asleep on Mars waiting for the right habitat to awaken and Dominate the local ecosystem. So we already done a pantsper me But when people talk about these ideas of terraforming Mars then that you know one big offshoot one flavor of that is that we use very hardy earth life forms as a way to jumpstart the process of trying to make Mars more habitable You want to thicken the atmosphere you want to regulate the temperature? You're gonna want to have life give you a hand with that we have lichens. We have mosses. We have fungi We have cyanobacteria of Archaea There's a lot of really extreme life forms that will get the process started and then as conditions improve Then more and more life forms will be able to come online and be able to participate in this process And so is that pantsper mea right where we are spreading earth life? intentionally to Mars to try and make the planet more livable and Would fungible grow in regolith? Yes, in fact researchers are developing methodologies to build bricks on Mars out of regolith and Fungi so you would have a bioreactor on Mars something that was brick-shaped and you would put into it Various fungi and you would put various growth factors for the fungible You know the food that the fungi needs and it would grow its mycelium networks and would solidify this brick into this combination of brick of regolith and dried mycelium and then you would be able to use this as a as a As building material, so they've also have bioreactors are building with say bacteria So there's a lot of ideas on how we can use life to make things on Mars So it's not just digging up bricks of regolith and baking it and then turning it into a building material But actually you could do because then you can do things like repair you could have You know parts of your habitat are cracked you can actually stimulate the The fungi in the wall to help repair it which is pretty cool So there've been knack awards donated or there there've been knack awards that have been awarded for this kind of thing So yeah, the people are thinking about how we can use bacteria fungi other Lifeforms to help aid in building construction materials and stuff on Mars and the moon It's time to show our all the new five dollar patrons and above Larry Kamin Jerry Adams Sabina Mehmet Yusseh Daryl Schnepp John Ashenbrenner John Tom Ross Joe Rolf Kenny Chris and Jean Levchin join the club at patreon.com such universe today Our zone so as the moon supposed to become the new International Space Station meaning there will eventually always be a group of astronauts Doing experiments on the moon instead of in orbit the hope is that we will have both that we will have a Group of astronauts in orbit around the earth at the International Space Station or some version like obviously the ISS will eventually come down But there will be some version of a space station then there will be a Permanently inhabited base on the moon and there will be astronauts there and you can like look up at the moon and know I mean it's really incredible that from when the International Space Station was launched until now like it was 1999 here. We are 2026 Closing on 30 years there have always been people in space Is that amazing? And so we will reach this point where There will always be people in space in orbit and there will always be people on the moon and there will always be people on Mars And then eventually there will always be people at asteroid station alpha and that'll just be incredible You know people is asked like why didn't we go back to the moon like after we went there in the 1960s and 70s? Why didn't we go back? We didn't go back because it was too expensive because we didn't have the technology That priorities had shifted and it wasn't the kind of thing that you could just fund And get on with the other things that were going on at the time now even in a relatively small budget for NASA something in the 25 billion dollar range if spent well can allow you to do Exploration out into the solar system and so it's just you know, we're seeing the rise of reusable technology We're seeing the miniaturization. We're seeing international collaborations. There's just like a lot of of Cool things are lining up all at the same time together to make this work T car 925 how much light illuminates the dark side of the moon? Where is it coming from? I forget the exact amount so the first thing is to remember that You know, we always talk about the dark side of the moon and the far side of the moon So, you know the side that we can see is the near side of the moon and the side that we can't see is the far side of the moon And that is because the moon is tidally locked to us And when people talk about the i'll see you on the dark side of the moon Sometimes the dark side of the moon is the side that we can see because the moon is going through its 28 and a half day cycle Where it goes from light to dark dark to light And so when we are seeing a full moon The light side of the moon is the near side of the moon when we're seeing a new moon Then the dark side of the moon is the near side of the moon The parts of the moon that are dark They are illuminated and they're illuminated by the earth And this is a thing called earth shine And this is that essentially the light is coming from the sun It's reflecting off of the earth and it is illuminating the moon. It is allowing us to see features on the moon When it is in shadow and there's this uh Incredible photo of the Artemis 2 mission where the astronauts took a picture of the earth while the earth was in shadow It was nighttime on earth And yet it was being illuminated by the reflected light from the moon And so you could see the continents and clouds and all of that purely from moon shine like normally the moon's magnitude is minus 12.74 And that's when the moon is full And that can change right like depending on whether the moon is closer or farther to us and its orbit when it's hits full moon and so the new moon The reflected light from the earth Is magnitude minus three and a half And that is very bright um when you think about the you know You can see down like the magnitude system goes Negative number is so weird, but it's negative numbers to zero And then goes to positive numbers and so you can see with your unaided eye and perfectly dark skies Down to about magnitude six and I think it's like every four increases in magnitude are 100 times as bright So if you go from magnitude Six to magnitude two, it's 100 times as bright from two to negative two Which is very bright man. So it's so complex, but essentially it is very bright that minus three and a half Is an extremely bright object Venus is minus four So the new moon is almost as bright as venus. It's as bright as jupiter But it is expanded into the size of the moon as opposed to this very bright point like object But when venus is up you can cast shadows Web VG i'm a coder with multiple AI coding tools on my disposal What is something impactful I can do for astronomy and space community? Well, I think the opportunity right now is to do things with the vir rubin data So, uh, I did an interview about a month back two months back with one of the data brokers the people at the entaris project which is part of the noir labs and there's like seven different data brokers that are pulling material from vir rubin packaging it up and then people can code apis into it. There's Think which is the one that's specializing just on solar system objects. You can find asteroids comets planet nine um, and then I think the thing that would be most useful would be talking to astronomers or Just like looking in discussion forums where people are talking about things that they really wish existed And then make one of these things that you can develop your own interface that accesses the api from one of these data brokers And allows you to do Various interesting visualizations and alerts of things that are happening out there in the cosmos based on vir rubin data I put out a call last week for people to tell me about their projects I've gotten a bunch of people have have sent them in and I will definitely be giving some cool shout outs to interesting projects that you can try out but just 700,000 Things are happening every single night according to vir rubin It's too much for us to be able to understand someone has to sort and filter and Turn that into something that you can wrap your mind around That people can go online and they can just watch at this cool globe of the cosmos and see Supernova going off around us in all directions And and get a sense of of this active universe that we live in So I think that's the kind of stuff so build something cool using vir rubin data that lets regular people Understand and put into context the amazing stuff that's happening out there And if you make something really useful You will probably attract the attention of astronomers and they'll give you tweaks and they'll ask for For features that will make you know them able to do more research. So uh, yeah, it's man. It is such a Cool time a fertile time To build these kinds of tools. We are now in the era of big data and you do things with Gaia data with Euclid data Like it's just it's unlimited the new dark energy survey is done The dark energy spectroscopic instrument just released their new survey. There's so much out there So much data that people need to be able to go through All right, those are all the questions that we had this episode. Thank you everyone who uh, Put your questions into the youtube comments everybody who joined me for the live show As I mentioned in the previous episode this week We are off for a couple of weeks with the live shows, but we'll still be producing a lot of content I'm just going to be on the road and so it'll be a different background For the introductions, but we've got lots and lots of material to still bring to you because we record so much Um, now I'm going to give you an update on all of the shows that I have been watching but first I'd like to thank our patrons Thanks to Abe kinks and Andrea Padre Brian Bodie, Caroline Chuck Hopkins, Commander Baila, Darkfinger, David Guilton and David Matz and Thrallor reading and Math for toddlers Eric Lindstrom, Evan Dot Perot, James Clark, Jeremy Madden, Jim Burke, Jordan Young Josh Alts, Marcel Sultz, Michael Purcell, Nord Space, One Step for Animals, Doug Please follow me if you had Vibrick 6994, Renkaiti, Richard Williams, Sean Sargent, Stephen Fiala Munney, team 49, Tilsaps Canada, Vlad Shimpland, Wolfgang Klotz and Zelda board galactic defender who support us at the master of the universe level and all our patrons all you support means universe to us So it's time to give you an update and a roundup of all of the shows that I am watching across all of the things uh, so I'll give you the one that I have most disappointed by first and that is for all mankind and I have previously put for all mankind onto my top 10 list of the best science fiction shows ever made and I stand by that for the first few seasons of this from when they sort of you know when the Soviets beat the Americans to the moon and then they sort of this leads to a new space race the kind of thing that we as spacers would love to see and then you see the colonization or like a station on the moon and then you see humans going to mars and then a city on mars But this latest season season five. It's just been kind of boring and there's been a lot of people The way I described it is just people walking down corridors on mars And it just hasn't been that great latest episode was pretty good that I watched but so far. Yeah, it's been disappointing So if you've been Holding off you can just kind of chill and wait till the whole set is ready or wait wait next year And then also on apple tv. I finished off watching monarch Which is the second season of this sort of in the Godzilla verse and it's it's fine It's it's okay. The shows that I really loved. We just wrapped up invincible Which is definitely in my top 10 list on prime. It's so good and this season was just amazing Man invincible is so good and then also on prime. We've got the final season of the boys And this latest season has absolutely been fire. I've just been really enthralled Best season I think so far of the whole show and it's really feels like it's coming to a conclusion You can kind of see how it's all coming together. So highly recommend The boys and then just for nostalgia. I went back and watched a couple of movies with my wife That we hadn't seen in a long time to watch dark city Which is this I like I can't even describe it Watch dark city. You'll love it and the iron giant which is just one of the best animated movies ever made About a giant robot and his best friend So definitely check both of those movies out if you haven't seen them. All right, we'll see you next week
