The bricks at the bottom of a skyscraper are pushed on by the column of bricks extending all the way to the top. As a submarine descends to a lower depth, the water pressure on the hull increases (as YOUR gravity force decreases, slightly, by a few hundred feed below the surface, by the way).

Science, unfortunately, has become bureaucratized and in a way that is not totally healthy: most academic study is not academic any more but geared towards fundraising (i.e. grants), and it doesn't matter if you have a good idea, what matters is whether it gets funded. > Cheers, > Arindam Banerjee >> >>>> It also throws out the theory that the Sun is say >> >>>>> a huge hydrogen bomb, causing fusion naturally at the core as the >>>>> temperature from extreme pressure is incredibly high.
