we ve seen planets that are like the earth and we ve looked for atmospheres of them, because we re going to have the possibility of detecting life on those planets. so it has done everything from showing us star formation to the birth of the universe to alien worlds where there might be alien life. it s been amazing. in fact, let s zero in on something about that. a colleague of yours, an astrophysicist at harvard has discovered miniscule fragments of what could be alien technology. he says that they are made of an alloy that doesn t match anything in our solar system, so help us understand. what do you think about that? yeah, so the good news here is compared to most of the ufo kind of craziness, at least here you ve got data that people can work with, that other scientists can look at this and decide is there any claim to this. the bad news is this probably most of us are skeptical because
we ve been able to look back in time over 13.5 billion years to sea see some of the very first galaxies that were born after the big bang. we ve seen these really incredible clouds on titan. we ve been able to look in detail at the atmospheres of exo planets, planets orbiting other stars outside of our solar system, and we re all long learning more about our universe in scales all the way from our sort of cosmic backyard to the solar system, all the way out most distant reaches of space. dr. amber straun, thank you so much for your expertise and your time today. really appreciate it. coming up, cnn s wolf blitzer is live in vilnius, lithuania for president biden s trip. obviously this was a very important moment for president biden and ukrainian president volodymyr zelenskyy. very important for both of these presidents, jake, and they seem to have patched over some of the problems, certainly the
passengers, inside this vehicle, able to make these trips. right, anderson. so, you know, any time you start a design on a submersible, it kind of focuses on capacity delivery. what s your mission? how deep are you trying to go? what panel are you taking with you? and how long are you trying to stay there? and that s going to kind of define your the inhabitants are going to be in. it s going to define the capacity of your life support systems. and the depth is certainly going to define the hull material. now, as you add more and more people, you need to shift away from the ideal shape, which is a sphere, to a cylinder. and it s all designed to really withstand the high pressures of that environment. at the depth of 12,500 feet, you re dealing with about 380 atmospheres of pressure. that s the equivalent of an adult male rhinoceros standing on every inch of that
coming or no? you have to wonder if there was some kind of structural failure going on, whether they might have heard some creaking or cracking. i think that is possible but once the structure was breached, that massive pressure, up to 360 atmospheres, the inrush of water would have been extremely fast. at that pressure, the gas would be so dense that they would be unable to breathe it in. in any case, the narcotic effect of the nitrogen would have instantaneously made them unconscious and their chest would have been crushed stayed away and they would ve had cardiac arrest no question. thank you so much. i appreciate that. sobering and sorrowful but we can all next, much more on the search for answers in the implosion of the titan. plus ukraine now claiming russia is planning to launch a terrorist attack at the largest nuclear power plant in europe. nuclear power plant. and another republican candidate jumping in the race to beat
a very, very rapid increase in pressure that these individuals were exposed to. that would have had two main effects. the pressure of the nitrogen actually has a very powerful narcotic, an anesthetic. anyone who is a diver knows that the deeper you go, the more narcotic and impaired you get just from the nitrogen in the air. it would have been a very rapid increase in the nitrogen pressure in the peoples brain and it would have been like a massive anesthetic overdose to be honest. it would have been instant loss of consciousness for that reason. the second thing that would have happened is that all of the body cavities and spaces that contained air, they would have been crushed instantaneously from the massive pressure. at that depth, we are talking about 360 atmospheres. all of the air spaces would have basically been crushed flat very, very quickly. what are the consequences of that? the chest cavity itself would
