# Oscillating Formation of Spherical Mass in elastic universe

• FallenApple
In summary, the presence of concentric shells of mass in a universe would lead to potential energy and potential collisions, and the presence of a point mass in the center would greatly affect the dynamics of the system. The scenarios presented may not fully depict the behavior of such a universe and further research is needed to accurately describe its dynamics.

Situation, a empty universe where there are only concentric spherical shells of mass dm spaced apart by distance dx and contracts under gravity to form a sphere. Assume that there is a point mass in the middle of all the shells. I don't think it would work without it. case1 is an inelastic universe.
case 2 is an elastic universe.

case1: There is potential energy in a separation of masses because they have a natural tendency to accelerate towards each other. As infinitely far away concentric shells contract, they contract faster and faster. As the shells of masses fall on top of each other, they hit the uncompleted sphere at slower and slower final velocities. Because the uncompleted sphere is not moving, it has internal energy. So the internal energy of the inner parts will be more than the internal energy of the outer parts. Until it all evens out. So what we should have in the end is a vibrating sphere of mass M( sum of all the dm).
Case2: the first concentric sphere will rebound off of the center point mass and have an radially outward momentum because this collision is completely elastic. The second shell seems like it will have less momentum, but it was further away by an amount, say dx, resulting in the equal but opposite momentum with the second shell. This causes an inelastic rebound of the second of the second shell and so on. Finally, the last shell will just rebound, then the second to last, and so on. So the sphere will just disassemble itself in an elastic universe. And this process will just keep oscillating in an elastic universe.

So in an elastic universe with only these concentric shells, it will just be a continuous formaton and deformation of a sphere of mass with time. Is this logic correct?

I would like to provide some insights and clarifications on the scenarios described above.

Firstly, in a universe with only concentric shells of mass, there would still be potential energy present even without a point mass in the center. This is because the shells themselves have mass and therefore, they would still have a natural tendency to accelerate towards each other due to gravity. However, the presence of a point mass in the center would certainly affect the dynamics of the system.

In case 1, where the universe is considered to be inelastic, the scenario described is plausible. As the shells contract towards the center, they would gain kinetic energy and eventually collide with the uncompleted sphere. The resulting collisions would lead to the redistribution of energy, resulting in a vibrating sphere with a total mass equal to the sum of all the shells.

However, in case 2, where the universe is considered to be elastic, the described scenario may not be entirely accurate. In an elastic collision, the total kinetic energy before and after the collision remains constant. Therefore, the shells would not lose any energy as they rebound off the center point mass. The momentum transfer between the shells would also result in a continuous oscillation of the sphere, but it would not disassemble itself as described.

Additionally, it is important to consider the effects of angular momentum in this scenario. The shells would not only have radial momentum but also angular momentum as they contract towards the center. This could affect the dynamics of the system and lead to a different outcome than described.

Overall, the logic presented in both cases is plausible, but it may not accurately describe the dynamics of such a universe. More research and calculations would be needed to fully understand the behavior of this system and to determine the accuracy of the described scenarios.

## 1. What is the "Oscillating Formation of Spherical Mass" in an elastic universe?

The "Oscillating Formation of Spherical Mass" refers to the theory that describes the behavior of a spherical mass in an elastic universe. This theory suggests that the mass will undergo a repetitive cycle of expanding and contracting due to the elasticity of the universe.

## 2. How does the elastic nature of the universe affect the formation of spherical mass?

The elasticity of the universe allows for the formation of spherical mass to undergo oscillations, meaning it can expand and contract in a cyclical pattern. This is due to the fact that the universe is constantly expanding and contracting itself, creating a dynamic environment for mass to form and behave in this way.

## 3. What evidence supports the theory of "Oscillating Formation of Spherical Mass" in an elastic universe?

There is evidence from observations of the cosmic microwave background radiation that suggest the universe has undergone periods of expansion and contraction. This supports the idea of an elastic universe and the potential for spherical mass to form and oscillate within it.

## 4. How does the concept of an elastic universe differ from other theories of the universe's behavior?

The concept of an elastic universe differs from other theories, such as the Big Bang theory, in that it suggests a cyclical pattern of expansion and contraction rather than a one-time event. Additionally, it takes into account the elasticity of space and time, rather than just the expansion of space.

## 5. What are the implications of the "Oscillating Formation of Spherical Mass" theory for our understanding of the universe?

This theory challenges traditional ideas of a singular beginning and end of the universe. It also suggests the potential for the universe to exist in a perpetual state of expansion and contraction, providing a new perspective on the evolution and fate of the universe.
