@Jackeea(View Post) Technically no. Assuming that there babies being born all the time, we can assume two can be born within close enough time within each other to be born at the same time. The close enough time would be so that they have there matter probability wavelengths equal to birthing at the same time. (a small value, 7.3039897 × 10^-34, but possible none-the-less) something that couldn't happen within immediate families (assuming traditional mother/father parentage (I.E. excluding same-sex marriages)) because birth is sequential per mother.
The smallest amount of time that is measured is approximate to 0.000000000000000000000000 00000000000000000005391 seconds. There are approximately 6.77 billion people in the world.
But, that would be relevant with matter wavelength theory. Real seconds, the chances are much, much higher, of course.
@qaddosh(View Post) That has no relevance to the math behind my reasoning. It does not have to be measured to be true. Also, the current population means nothing in worldwide birth-rate. It is 4.17 babies on average, average birth speed is about .5 m/s and the wavelength of a baby is 7.3039897 × 10^-34 m.
