Bubbles Definition and 107 Threads

just something i been thinking about lately in relation to how causal dynamic triangulations connect to form spacetime When one bubble meets with another, the resulting union is always one of total sharing and compromise (Human beings could learn a lot from bubbles.) Since bubbles always try...

This is an interesting questions that occurs when we have a glass of champagne (or cava). why all the bubbles that are born in one point, are lineed when they go to surface? An the other hand: why are they at constant velocity, and not with acceleration? Chin chin! R. Aparicio.

I have read a lot about eternal inflation and as I understand it Guth and others are now arguing that once inflation has started, it is an ongoing process. However, my question is, once inflation had finished in one Universe and inflation had started somewhere else, wouldn't the expanding...

Is it possible to make very clear ice in a home freezer? Tap water ice is often cloudy white, which I think comes from minerals in tap water. Making ice with distilled water is a pretty conclusive experiment, I think. However, the ice cubes I make with distilled water still have many small...

Hi, Why do some soap bubbles stay intact for longer periods?And what is the reason for the changes in color of the bubbles? Thanks!

I'm curious about some fluid dynamics stuff, and my first series of questions I have are to do with how air rises out of water... Having done some scuba diving, I know that divers use bladders to achieve neutral bouyancy and positive bouyancy so as to hover or rise through the water. Now...

I heard about a technique where mercury or some other liquid is spun in a dish until it assumes a parabolic shape. Would this work in space? Could a flat membrane of liquid metal do just as well? It could be liquified by an electric current and start out flat like soapy water in a bubble wand...
