The Titanic would still be sailing, possibly.


If ice were denser than liquid water, icebergs would likely sink (even given that sea water is denser than normal water). If this were the case then oceans would likely freeze over. (For example, ice laid down in the winter months would not completely thaw in the summer months, and the next winter cycle would result in a net increase of ice).
