    Spheres
In summary: I like it.In summary, you think that objects tend to look more like spheres because they move slower or less in comparison to other objects in space-time. The Earth also appears to be a sphere, though it is moving fast. There are many spheres throughout nature, including in the planets, stars, and galaxies.

In space-time I like to think of objects going through a "stream" of movements that remain concrete in the 4 dimensions of space-time, all movements being inter-related with one another with respect to the frame of reference. But let's compress this stream so only what remains is the overall average of the movements made by the object in space-time. I envision a sort of spherical shape. The less an object tends to move it's parts the more it will appear to be spherical in form.

Imagine a tree, to help look at this image http://www.sustland.umn.edu/implement/images/planting_fig1a.gif

Gives you an idea as to how an object can appear to look like a sphere. A tree doesn't move very quickly relative to the Earth year, or the ground for that matter, so it doesn't really change its form much from that of a sphere.

Now imagine a human being, in the form illustrated by Leonardo Da Vinci

As you can see, the human doesn't look like that much of a sphere. Overtime, on average however, the human will tend to look like a sphere. Waving your limbs around in the 3 dimensions of space will allow you to see that you can indeed look more like a sphere, but this is only averaged overtime.

The connection to the tree and the human is this: The tree moves a lot slower relative to the human being. The human being moves a lot faster relative to the tree. The tree will tend to look more like a sphere because of it's relative speed to that of the ground of Earth or it's inertness, if I am using that right.

The Earth looks quite like a sphere, though it's moving fast. But we're talking relativity.

Am I making sense here or is this ridiculous?

I don't see this as meaningful to a philosopher or a physicist, but I can see how a poet, novelist, or filmmaker could create something mentally entertaining with it.

Thank you for your comments, Math is Hard. I, too, do not find any application for such thought. It is just peculiar that things will tend to shape themselves as spheres in this universe, if you suppose time a little differently.

I thought about this for many animals and things. The hardest one so far is the snake, which would have to wiggle quite a bit to tend to look like a sphere. But indeed, it would, averaged overtime. So many things tend to look like spheres. Also, as something ages, it's sphere size changes. A baby for instance has a smaller sphere than an adult.

We think of atoms in two different ways. Bohr's Model, which describes the atom as a 'mini solar system'. Doesn't this, sort of as well look like a sphere? Then we see the wave probability of the atom and it's particles and we find that, averaged over time yet again, the particle will tend to look like a sphere or a billiard ball. Even in wave form, it tends to look like a sphere.

You find spheres all over in nature, including the planets, stars, galaxies tend to spiral and turn in nature. There are a lot.

My question is: Why? Why do things tend to look like spheres? Is it because of the 3 dimensions of space, or is there another more subtle reason to this? Do Membranes in M-theory have anything to do with this line of logic? Probability of tendency in shape?

I do see, though, that this is far from applicable in Philosophy or Physics, but the thought that reality tends to work this way still exists and we can be left to ponder why.

It is actually an ancient question in metaphysics and physics dealing with idea that symmetry or proportion apply to everything.

Modern physical theories tend to have what is called "supersymmetry". This is a type of symmetry that always looks the same from every direction, even if you cut the figure into little pieces. For example, cut one of your spheres up and you just get more spheres. A holographic picture of a ball is a common example of this type of symmetry. No matter how many piecies you cut the holographic film into each piece retains the overall picture of ball instead of a corner here, a center piece there.

I like spheres because they represent flat planes in a coordinate matrix skewed by centripetal force. I wonder if anyone ever thinks that the same way the Earth appears flat on the surface, the solar system, galaxy, etc. might just appear flat because of our location on its "surface." I don't know how this could be possible considering that galaxies are observed to be flat at a far distance, but then maybe each galaxy is just a "plate" on the surface of an expanding sphere. Anyway, the point wasn't really to speculate but to illustrate that there is a perceptual tension between 2D planes and sphere-surfaces where centripetal force is present - I just wonder how much this effect could explain.

Who needs centripetal force? A large enough sphere will appear to be flat in local areas, regardless of what forces are acting on it.

I guess that's a good point, but wouldn't that be true of any 3D shape, such as an egg or a doughnut? I like the centripetal force because it causes the sphere's surface to be literally flat in terms of all lines of force being perpendicular to the surface. Would this be true of any other 3D shape?

Sure. But objects with a much higher curvature would have to be relatively larger to provide that same sense of "flatness".
 

1. Why do I like spheres?

There are many possible reasons why someone may like spheres. For some, it may be because of their symmetry and perfect shape. Others may find them aesthetically pleasing or soothing to look at. Additionally, spheres are a common shape found in nature and in man-made objects, so some people may appreciate their familiarity and simplicity.

2. What are some common things that tend to look like spheres?

The most obvious examples of things that tend to look like spheres are sports balls, such as basketballs and soccer balls. Other examples include planets, marbles, bubbles, and some fruits like apples and oranges. Man-made objects such as globes, light bulbs, and Christmas ornaments also have a spherical shape.

3. Are spheres the most perfect shape?

This is a subjective question and opinions may vary. Some may argue that spheres are the most perfect shape due to their symmetry and lack of sharp edges or corners. However, others may argue that other shapes such as cubes or pyramids have their own unique perfection.

4. How do spheres form in nature?

Spheres can form in nature in a variety of ways. One common way is through erosion and weathering of rocks and minerals, which can create spherical shapes over time. Another way is through natural processes such as crystallization or growth patterns in plants and animals. Spheres can also form in space through gravitational forces, creating celestial bodies such as planets and stars.

5. Can spheres be used in scientific experiments?

Yes, spheres have many practical uses in scientific experiments. In physics, they are often used to model and study the behavior of objects in motion, such as in projectile motion experiments. In chemistry, spheres are used in titration experiments to measure the volume of a liquid. Spherical lenses are also used in optics and microscopy. Additionally, spheres are commonly used in mathematical models and simulations to represent objects and their properties.
