What If Babies Were Born In Space? A Doctor Explains

you ask me you'll fall back to the first half so I've just come direct from University College Hospital I had an appointment this afternoon with my wife got some news expecting a babies we had our antenatal scan you're not contractually obliged to make any noises because it's the second one and let's be honest nobody gives a about second believe me I know but I have just had my first nephew who was born two days ago so it's a special time and I look at these two miracles of life and I think what only normal rational person would think and the only thing you could think really is what were these babies be like if they grow up in space I'm doing a PhD at the moment so that means I spend the majority of my time watching Netflix we're getting particularly intuition or the expanse of integrity so the expanse is not as I originally thought a documentary about the large blank space on my CV where publication should go it is actually a sci-fi thriller sets a few hundred years in the future where humans are born and live in zero gravity so I started thinking what would that actually entail one of my degrees is in space medicine sorry that sounded really thick it's one of my degrees Tony Stark has got three PhDs and Sam Beckett quantum leap over him he had seven PhDs and as a kid I thought that was really impressive to have a bunch of degrees and then when he started PhD you realize doing seven is possibly the stupidest idea anyway so I floated the idea of calling my nephew casein my child control and experiments on there but my cousin wasn't too keen on the idea and besides they're not even born at the same time they're not ideal comparators you need two identical twins and a lot of you will probably be aware that NASA did indeed have some identical twins to study Scott and Mark Kelly are identical twins and Scott Kelly went to spend about eleven months on the International Space Station while Mark stayed on the ground and when he came back I don't know if you remember these shocking headlines a couple of months ago that Scott Kelly as DNA had changed by seven percent from his brother when he came back they said you know this is this is shocking stuff that there was radiation in space and they've been transformed so what they're actually saying is that a human went into space when a rhesus monkey came back because a rhesus monkey is 7% different in DNA from a human 99.9% of our DNA and identical twins surprisingly share 100% what they were talking about of course was gene expression which is neither here nor there in this context the Telegraph which that first headline this one decided to double down on their stupidity and say that Scott Kelly because of all the changes in space Maine actually now be older than his Twitter and I've got a quality that my wife is very fond of which is I can't let any mistake go on correctly so I wrote to the senator and I said Scott Kelly I was traveling at 17,000 miles an hour for 11 months that is 0.0025 percent speed of light special relativity therefore dictates that he would have aged 13 milliseconds less than Han even on the ground however I know you're thinking Mark Kelly was further down as gravitational well and there'd be some time dilation I factored that in milliseconds oh he's 8.6 milliseconds younger and he would have been had he stayed on yeah we can we can depict this graphically that's the earth you can see he's a Titan that's the gravitational one of the other time dilation is minimal so a bigger body Sagittarius a star the supermassive black hole of the center of our galaxy is it's got much more pronounced time dilation a minute on the event horizon there would be years on earth and this is a scientific conference this the audience and Jesus come up to the moon consent this is more of a comment than a question but by that stage across the event horizon of the question you can't escape and as you fall down the gravitational wells today you may be interested in my own research and when you reach the bottom time actually stops in time so if we could get so if we had astronauts in space could they actually get pregnant and the official knowing from Ross cosmos and NASA is that nobody has actually had sex in space there are lots of rumors taking on their work however we know that mammalian sperm actually struggles in zero-gravity we've tested a few species other species are okay but mammals seem to have a problem their sperm don't swim properly in zero gravity so the last SpaceX supply run with twins are fifteen weeks ago so the ISS actually took bull and human sperm sea men here are about two they're about to shoot their load their payload into space and so right now the ayah says they are actually testing human involves Behrman as you can see they are very very serious we're really enough map greening will actually Commission to do the mission patches is entirely real so if we get pregnant in space maybe we can send babies from earth into space so I was happy to volunteer my nephew as tribute but we'd have to get part of the ethics committee and right now so I'm a cardiologist by trade I'm trying to set up with trial at the moment and ethics committees are the bane of my life I'm trying to recruit patients having heart attack since they I think so many say no you can't recruit patients when they're having a heart attack because they're gonna be in immense pain they won't be thinking straight they can't consent first of all I didn't even have heart attacks were painful but then I said fine I'll just dug them up with morphine and they said no I had strong painkillers they won't be thinking straight they can't consent I was like guys it's almost as though you're not happy for me to delay a life-saving treatment with an autonomous unnecessary conversation how about a trial that almost certainly won't benefit the patient in any way I may be going out on a limb here but the inability to send babies into space or to prolong someone's heart attack is why brexit happened so when you get into space there lots of changes to the human body you're probably aware of some of them your bones lose density they become brittle you lose a fifth of your circuiting blood volume you become anemic your muscles atrophy your heart gets smaller your fluid registrants into your trunk your head gets puffy your eyes get squashed it's there's a lot of stuff happening so we can depict some of the science graphically here's a graph I'm sure you've all seen before it's venous return notice similarities between a graph of stinkiness desperation distance from the nearest alleyway and this graph is willingness having 50 that shifts the dissociation to the net this is a sake dance of my own research this is a loss of line crossing through multiple point data points without actually interacting with any of them points are is in fact women and this line that passes through land without touching one at any time is of course an engineering - you all know this one but this is this is blood pressure passing from the arterial to the venous system but you know it's also got striking similarity to an analysis of this standard routine he's already appreciation on the left the y-axis in time here's where I told a good joke we're told a bad joke by the end of the routine warnings appreciations an all-time low when you want me off the stage and you can notice an inflection point where things started to go wrong here and that's when I started showing again stage as you can see after an initial elevation there is an inexorable decline in all of these lines and they just they just keep going down and down over time and I realized that so if you take a look closer at these lines they are money happiness romance fullness of rewriting manuscripts appreciation of the peer-review process and the will to continue living because of course this graph is doing a PhD but the shock white amongst you would have noticed that there is one line which rises the whole way through that is the desire somebody [Applause]
