I like this Inward Expansion, even if it is an oxymoron. You see, the alternative... 'implosion' ... has an opposite - 'explosion'. But I don't see Outward Expansion as, necessarily, an explosion. I mean, the Cosmos is supposed to be Expanding Outwards - but we don't say it is exploding.

Not really joining in, just lurking, I have no position on either side of this debate. Although I had heard about incompressible gasses before and thought I would provide a link.

In a static system the outward expansion would slow as the volume increases, but what if the system isn't static? What if the energy causing the expansion is increasing?

Anything helpful is appreciated. Thanks for straightening me out. But Kelfazin, do you know of an outward expansion that speeds up? Could there be such a thing? |

![]() It really comes down to the rate at which the volume is increased; if you can somehow manage to keep increasing the rate of volume increase sufficiently, you could maintain an increasing rate of increase in the diameter, too. But the rate of volume increase would have to continue at an ever increasing-rate to maintain that sort of ratio. I don't know that I have much else to add here (or that I've even added anything at all anyway), but I gave it a shot...!

Not 'addiing' anything, I think, implies a static system, or at least a closed one, and in a closed system, you couldn't (by definition) add energy (and (being able) to do so would then make it an open system, not a closed one).

Something else to consider while you blow up the balloon: When the balloon is flat, you have to apply a large amount of pressure to begin the inflation. It's hard to get it started. But then once it's started, and before it starts to reach its maximum size, it's a lot easier to cause expansion with less pressure. So right as you cross that line from initial expansion to full expansion, you have an increasing rate of expansion with less expenditure of energy and pressure. Then as the balloon reaches maximum size, you have to increase the pressure to keep the volume going up.
Maybe we can apply this to the expansion of the universe. The BB was the initial, high pressure expansion, now we're in the "middle" low pressure, high expansion state, and in the future we'll hit the high pressure, low expansion state. I dunno. Do I know how this applies to whatever your position is? Not really. Just a thought ![]()
