    Hello, I was having a conversation with a friend. I said that if you build a house the earths weight wouldn't change. He was ok with that but he said that if you give birth to a child the earth would weigh moore. I know thats wrong, but I have nothing to back me up, and I can't find anything about this..

    To clarify, my question is:

    If you give birth to a child would the earth weigh moore than it did before?


    Thanks in advance
    Best regards

    No. The "stuff" the child is made of comes from what is already around; i.e. what the mother eats. Remember matter/energy cannot be created or destroyed.

    Where does your friend think the extra mass comes from?

    Clearly your friend is not a woman who's ever carried a child to term.

    Getting 'a weight off your mind' isn't even in the same league as getting a child's weight off your pelvis.

    If you need something "official" to back you up, I believe the law of the conservation of mass would apply here.

    Earth's mass is constantly increasing but, that is due to things from space bombarding the planet.

    Actually, just saw a science article that said the loss from the atmosphere is greater than the gain from meteorites, so the earth's mass is decreasing, by a very very very very very small amount over time.

    Curious what exactly is that "loss from atmosphere"? And I think that depends on how big those meteors are

    Mainly hydrogen and some helium. This might be the article: BBC News - Who, What, Why: Is the Earth getting lighter?

    That was it, thanx, Strange!

    (PS, since it was the BBC, I should have said semi-scientific, since they have a mixed track record.)
