This is how all life on earth evolved. In fact, we push out all the time. I am sure you have seen movies in which some characters are pushed out into space. If the movie is done correctly you will see the persons body continue to push outward without anything pushing back. Now, if you want to see something get crushed under the pressure of a fluid you can go deep into the ocean.
Water pressure is much greater than air pressure.
Humans can go only a couple of hundred feet, with training, deep before the pressure of the water is more than our bodies can bear. Make sure to include the above question in your e-mail. All rights reserved. Please, read our legal info before using this site.
