According to Einstine, since all motion is relative to something, it would logically follow that there must be a point in the universe that everything is relative to. Is there such a point, or was this idea disproven later on?

When I make a martini in my cocktail shaker I add ice, gin and vermouth. The ice is cold (naturally) but the gin and vermouth are at room temperature. The shaker is kept in the freezer already filled with ice - ready to go when I get home. I add the gin and vermouth as above, put on the lid and shake. Air pressure rises in the shaker as I do this, occassionally pushing off the lid slightly so contents are forced out with a hiss as the air is expelled. This seems contra-intuitive. Once would expect the air inside the shaker to be chilled by the shaking and the pressure to fall, sucking the lid on tighter. Why is it so?
