Why, they ask, did he not confess his supposed hoax immediately after the release of Joseph Smith’s initial translation?

What if the scan shows a problem? What is an ultrasound scan? An ultrasound scan sends sound waves through your womb uterus. These waves bounce off your baby as echoes. Hard tissues, such as bone, reflect the most sound waves and so make the biggest echoes. These appear white in the image, and soft tissues appear grey. Fluids, such as the amniotic fluid surrounding your baby, appear black.

This is because the sound waves go through them with no echoes. The person performing the scan sonographer will look at these different shades to interpret the images.
