Undergrad Why do objects with mass attract each other?

Click For Summary
The discussion centers on the understanding of fundamental forces, particularly gravity. While the strong nuclear force is well understood in terms of why protons stick together, gravity's mechanism remains unclear to some. The question raised is why the explanation for gravitational attraction is less satisfying than that of the strong nuclear force. The distinction lies in the perceived lack of a deeper understanding of gravity's underlying principles compared to other forces. This highlights a gap in comprehension regarding the nature of gravitational interactions.

In most cases, we know why things happen. Protons can stick with each other because of the strong nuclear force. There's all kinds of forces and we know mostly about why they occur and how they are transmitted.

But I don't understand gravity. Why do objects with mass attract each other ? I know how to calculate it, but I can't seem to understand how it works.

If you're satisfied with the explanation, "Protons can stick with each other because of the strong nuclear force,", why are you not satisfied with the explanation, "Two massive objects attract one another because of the gravitational force." What's the difference between these two explanations?

Thread 'What is the pressure of trapped air inside this tube?'

As you can see from the picture, i have an uneven U-shaped tube, sealed at the short end. I fill the tube with water and i seal it. So the short side is filled with water and the long side ends up containg water and trapped air. Now the tube is sealed on both sides and i turn it in such a way that the traped air moves at the short side. Are my claims about pressure in senarios A & B correct? What is the pressure for all points in senario C? (My question is basically coming from watching...
