How Giving Birth In Space Will Be Different


Narrator: Scientists have studied a lot of pregnant animals in space, including salamanders, fish, and rats, but not humans. Over 60 women have traveled to space, yet none were pregnant during the trip, let alone gave birth while
floating in zero gravity. But with talk of future space
colonies and cities on Mars, there’s a good chance that one day humans will give birth
somewhere beyond Earth, and that brings up some
interesting questions. What will it be like? How will space babies look? And ultimately, how will giving
birth in space be different? The most obvious difference is
the low-gravity environment, and without the aid of
Earth’s gravitational pull, it might make it more
difficult for the mother when it comes time to push the baby out. Plus, if one day women
lived in space permanently, some of the risks of pregnancy would be much greater than on Earth. For one, without the
stress of Earth’s gravity, her bones lose density. Studies show that
astronauts, for instance, lose 1% to 2% of their bone density for every month spent in space, and that would be especially
concerning for giving birth because the pelvis could
fracture in the process. In fact, doctors recommend
that women with brittle bones avoid a natural birth altogether, which could mean births in space would be left to other methods. Scott Solomon: That could lead to an increased reliance on C-sections for childbirth for people living in space. Narrator: That’s Scott Solomon, an evolutionary biologist and
professor at Rice University. He walked us through what space might do to generations of humans born
in low-gravity environments. We already know that the way we give birth influences our anatomy. For example, the size of our heads is restricted by the size of
our mothers’ birth canals. Solomon: With more
C-sections, that could lead to larger heads in our descendants because they wouldn’t be constrained by the size of the birth canal. Narrator: And down the road, larger heads wouldn’t be the only major change. We may also change color, says Solomon. That’s because in space
we have less protection against harmful space
radiation like cosmic rays, so to counteract that, we may evolve Solomon: new types of skin
pigments, like the melanin that protects our skin from
ultraviolet sunlight on Earth. That could mean that future
generations living beyond Earth will evolve to have different skin colors. Narrator: The more melanin you have, the darker your skin. So Solomon predicts that
people living in space may develop darker skin over time. But he says these changes might
take centuries or millennia for enough time for many generations of women to give birth in space. Solomon: Eventually,
people living in space could evolve to be different
enough from people on Earth that we would consider them
to be different species. Narrator: But for now, we just need one very brave woman to pave the path.

  1. I was hoping for him to say larger brains. If it said larger brains, then I would be like 'Send people up there, pronto!!'

  2. Oh shit humans are arrogant can't get shit together on earth and these morons are talking about space yall won't make it I GUARANTEE it

  3. If we move to space expect no birth from women, well, only if some 15 yearl old girls do un-safe sex there would be a chance.

  4. Meh, all humans will die before even building a colony out there, how about actually living and reproducing.

  5. But there are no selection pressures…babies with big heads in the world don’t die in birth, the mother gets a c sections. So we would be seeing bigger headed babies now if that were true. Putting any species in such a different environment is going to kill it off before any slight bit of evolution can happen…and if you protect it from the environment then there’s no need for evolution as there’s no pressures.

  6. There is a problem with the we will evolve to be different species thing

    If travel is fast which will certainly eventually be, the populations won't be separated and therefore speciation won't happen.

    Also most genetic changes must be fast and easily reversible if you want to hop and live in many places on space and it's planets so it's likely instead of evolution genetic modification will be the thing that causes the entire human population to change

  7. You: *born in space*

    New year holidays: *everyone goes back to their hometown*

    You: Am I supposed to go back to space?

  8. What if the baby goes back to Earth, will Area 51 take them because they are considered as aliens?

  9. This is the sad reality, we are planning to leave Earth healing by itself, we only contribute to the pollution, and soon, we would do this to another planet.

  10. So you’re saying future generations of humans born in space will look like the Grey Aliens? Confirmed the Grey Aliens are just future humans?

  11. Have you ever heard the sentence:

    What may be predicated of any thing is wholly determined by the definition of that thing.

    If you had, if you understood it, one thing it would teach you is that you, and the rest of humanity are not functionally literate. Man is proto-linguistic.

    It means that you do not even know what you are, why you are or even how to do your biologically defined job.

    So, let me ask you this. What is the most important thing anyone can do to help improve the entire human race?

    Can you answer that question? You should know the answer immediately. But I trust you do not.

    A mind is one of the life support systems of the body. As such it has a well defined biologically determined job to perform and well defined biologically determined means of doing that job.

    Do you even know what that job is? It is just one thing like every other life support system.

    So, tell me.

    Let me ask you this. Are you familiar with punctuated equilibrium? Of course you are.

    What happens when a species reaches the punctuation mark between being proto-linguistic, to being linguistically functional?

  12. I'm quite curious who will be the 1st human to ever be born beyond Earth 🙄
    Right now, it's safe to say that 100% of humans have been born here on Earth

  13. There are four different theories about how the universe was born before the Big Bang
    The problem is that we need only one theory
    We need one theory that explains the emergence of the universe
    The first theory is the collision theory of cosmic membranes

    This theory says that the birth of this universe was caused by the explosion caused by the collision of membranes every trillion years

    The second theory is that the universe is the hologram world
    It is that the universe is a stereoscopic image of black hole information
    This means that our lives and our self-consciousness are just an illusion
    We are just an illusion and not a reality
    ‏The third theory says that the universe is just a bubble between an infinite number of bubbles of random inflation
    ‏The fourth theory says that the Great Bang created our world 14 billion years ago of white hole energy
    ‏‏But is there scientific evidence of the birth of the universe from this white hole?
    ‏ ‏The Continuing Problem There are four different theories about the birth of the universe
    ‏ ‏You must create a new satellite
    ‏‏In order to discover the oldest light in the universe
    ‏In order to discover the signs (Waves of initial gravity)
    ‏We need to create a number of new satellites dedicated to exploring scientific evidence
    ‏ ‏To confirm the hologram theory or evidence of the collision theory of those cosmic membranes
    ‏Or evidence supporting the hypothesis of inflationary cosmic bubbles

  14. stick your crotch out of the ship, and let the vacuum of space suck the baby out of you. problem solved 🙂

  15. Easy .. imitate the earths gravitic properties specific to that of earth. Don't forget to add all the other variables. lol Testing 1…2 .. testing.3…4 This is a test.

  16. That's why all of the descriptions of aliens always have such huge heads and little bodies? Aliens do C-sections and have no muscle mass?

  17. haha I like how you make it sound like no women would be brave enough to do give birth or be pregnant in space, when it's really about the moral dilemma of experimenting on an unborn human child like that. This has always been the reason why it hasn't been done, not because they could't find a single "brave" woman xD

  18. That child would not adapt well on earth. His bones would be too weak and you can’t exactly have a 1 week year old do extreme exercise

  19. Anyone seen the science fiction/teen romance movie THE SPACE BETWEEN US? SAD MOVIE, about Martian boy whose body could not handle Earth gravity.
