If I understood correct, you find some fossils of other bacteria in meteorite. Yes. But my question, where from this meteorite? The best evidence that the carbonaceous, the C.I.1 carbonaceous meteorites, the best evidence for their parent bodies, is a comet. In fact, the CM2s have been associated with comet thinly. There is a lot of reason to think that the parent body of the carbonaceous meteorites are comet. From the mineralogy, from the extensive actous alteration of all the minerals, there has been an enormous amount of water on the parent body. So my personal thinking is that the parent body of these meteorites are comet. Which could explain why the biology looks just like Earth biology. They could have accreted Earth biology by coming through ejecta fields from huge impacts on the Earth. Or they could have delivered biology to Earth as they fall into the ancient oceans. Either way, would give an identical set of biological entities that would have exactly the same characteristics and be indistinguishable. Thank you. Thank you very much. It is known that a part of meteorites, at least last, are well-known because they contain specific textures, contra-infondra. I have trouble hearing that. Do you know any data concerning possible delta state of comets that could provide a few ideas for life there? Any data concerning the possible water comets? Yes, in delta state of comets. Ah, possible melting state of comets. Well, we know that the dominant volatile of comets is water. We know that comets get hot. And physics says that when you raise water to a temperature above zero Celsius, it is going to go first from, based on phase change, diagram of water, first from solid to liquid. And then it provided there is pressure. If it is in vacuum, the surface ises would go directly from solid to gas. But we know that comets have a black crust. And therefore there would be regimes beneath this black crust of rock and melted organic type material, in which the pressure would first start building up. And once the pressure gets above 10 millibars, then the ice goes from solid to liquid state before it goes to gaseous state. So from physics, I can tell you I am absolutely certain that every comet develops pools of liquid water as it approaches the sun and gets closer to the sun than the orbit of the planet Mars. And that water stays and circulates throughout portions of the comet between the surface and the inner core until it starts going back out again, wearing it freezes. And then it remains in frozen state and any biology that was there would freeze. But what David Gilchinsky has shown and what Sabita Buzov has shown is that when you take bacteria and you freeze them, you put them in suspended animation and they can remain alive for millions of years. So I have a short question. All carbonic acid material rights, carbonic acid concretes have biosignatures demonstrated by the signatures as I understood you. And all maybe they are carbonic acid concretes without biosignatures. Are there carbonaceous concretes without biosignatures? Yeah. There are carbonaceous concretes that I have not found micro fossils in. Yeah. But I think all of the carbonaceous concretes have been found to contain amino acids. And maybe you're wrong about that. Do you happen to know Alexi? I guess it's hard to say when you're using the word all. I should put it this way. I know all of the CI-1 carbonaceous meteorites contain amino acids. All of the CM-2 carbonaceous meteorites contain amino acids. And nucleobases and in fact, mergeson contains tens of thousands of complex organic chemicals. So that's as broad as I guess I should go. But what about fossils? Ah, what about fossils? Well, we found fossils in a lot of them. But some are really prolific. Or Gaya is very prolific. Mergeson is very prolific. Some you find some fossils but not so many. You have to work harder. Sometimes, like we did once, hunting for two days on Nikolska, as Alexi will recall, and we found nothing. And I finally said, what kind of carbonaceous conrad is this? I don't know, Nuzarov did not tell me. So we started looking. We found out that we had done a stupid test because we didn't know what we were looking at, and it turned out to be a Stony meteorite. If we were imagining fossils in meteorites, we should have found fossils in that Stony meteorite when we thought it was a carbonaceous conrad. So there's some kind of incandes in the middle of the rice. You showed incandes. What are the different in the mental composition? Infosilized incandes? Yes. That incandescent contained about 2% nitrogen. Yes. That incandescent, well, I'm not sure whether it was an incandescent or a hetero-sist. The big round A, it's hard to tell whether it's something an incandescent or a hetero-sist. So it may have been a hetero-sist, but it contained 2% nitrogen. And I said, well, you know, hetero-sists are where the nitrogen, as enzyme is located and where the nitrogen fixation process occurs. And so maybe it was a hetero-sist and it had produced a lot of nitrogen. And there was still residual amount of the nitrogen materials that had been produced that made it possible to detect nitrogen in that particular form.
