Trying to udwrstand the physics involved in balloon. Consider a small blob of radius r1. You blow it to radius r2. Now at r2, the balloon is trying to get to r1. What keeps it at r2?

Also, say the ballon suddenly develops a tendency to shrink (i.e. its surface area begins to shrink linearly in time) then what would be required to keep it at r2? (You can assume a blower inside)

Would appreciate equations. Thanks.

Hello everyone thanks for posting your comments on my page. I am hoping to gain some knowledge about how how other dimensions can exist beyond the 3 dimensions that we exist in. I don't know alot about it, but i was hoping someone could explain how we can prove that there are other higher dimensions and are they spatial? or are they different somehow like in terms of time, energy, or something else? Please try and break it down to me in Lay mens terms thankyou.

Why did God use this physics law of Newton, Maxwell, Einstein, etc creating our world and not another laws?

If you placed a rock on a paper towel, the towel will sag and anything else on the paper towel lighter in weight than the rock will fall towards the rock.

Would I be wrong in assuming that space time is like a paper towel and that anything with mass causes lighter objects to fall towards the larger mass because of this funnel-like well the sag creates?

Take a look at this picture of a wormhole - that is where I got my hypothesis from...

For instance, heated waves comming off a hot road cause a shimmering or wavey effect to the image past it. Is the air acting as a lens? Can you use density of anything to warp or bend light / radiation?
