Dark Matter

Give me a fixed point, and I will lift the Earth from its hinges, the Greek Archimedes is said to have once said. Euclidean geometry requires a fixed point and specific directions. Contemporary physics seems to have found the fixed point in the Big Bang.
Two massive objects moving at different speeds possess kinetic energy. The location of this mass of energy depends not only on the observer's spacetime point. Their speed determines whether this mass is located with one object or the other. Potential energy is different. Both objects move in the same inertial frame. This mass cannot be assigned to just one object. In my opinion, this mass is dark matter. The potential energy of a soccer ball is small compared to the Earth and the Sun. However, compared to a galaxy like the Milky Way, it is likely to be significant. According to special relativity, the mass of kinetic energy is always in the observer's inertial frame, i.e., opposite to the moving mass. Since everything in the world is always in motion, I assume a fundamental nonlocality* of physical phenomena. Another example: the interference of light at a double slit. Here, energy disappears at one point but reappears somewhere else. The law of conservation of energy is not violated.
*This does not mean that everything is nonlocal; there is only always a nonlocal aspect.

Note:
On Wikipedia, under the virial theorem the potential energy for a spherical mass system (such as a globular cluster) is given as the formula:

In the explanation, it is used to estimate the kinetic energy of the system. This energy is negative and refers to the energy required if one wants to expand the system infinitely. I am not referring to this energy. It is not present, but virtual, and therefore does not form mass. You can see this because the radius is in the denominator. The larger the radius, the smaller the potential energy (in terms of magnitude) is.
The potential energy referred to as dark matter is positive, has mass, is actually present, and increases with radius. This results in the formula:

Here, U0 is an unknown maximum value. Because the expression must be greater than 0, U0 and U increase quadratically with mass. However, the potential energy associated with mass also increases the more parts this mass forms. New stars can be formed from dust and gas using this energy.
