What if you become a ... Dark Matter?
The human body is composed of about 10 28 particle conjugate together. An ordinary person weighs 50 to 100 kilograms and stands on the Earth's surface. But dark matter behaves differently. It does not interact with nuclear or electromagnetic forces. It does not interfere with other particles or with them. It interacts only with gravitational force and, as far as we can tell, the only force with which it deals. What would happen to you, with a man, if all of a sudden your body particles become a particle of dark matter?
The difference between what you are and what you can become huge.
On Earth, we are made up of ordinary matter: for the most part in the form of atoms. At the subatomic level, our atomic nuclei bind the strong nuclear force, which allows a wide variety of elements from the periodic table stably coexist in one body. It keeps the electromagnetic force your body into a unified whole, linking atoms in molecules, cells, organs and the whole body. Earth's gravitational pull keeps us on the surface, and the electromagnetic force between the atoms of the earth do not allow us to fall into the ground. Meanwhile Earth revolves on the solar orbit, which rotates in the galaxy which rushes through space.

Imagine that all the cells of our body are suddenly be at the mercy of dark matter?
What if instead of being composed of particles of the Standard Model that are experiencing the full range of fundamental interactions, we will turn into particles that interact only gravitationally? The first thing, of course, your body will cease to be bound into one, and you just disappear. Nuclear forces holding your core and protons together, evaporate; electromagnetic forces, which hold the atoms and molecules together, disappear; your cells and organs will simply cease to exist.
There will be no fantastic visual effects. You simply become invisible, because even the light will be reflected from your body particles
Instead, because of the thermal motion of the particles at a speed of approximately 3,000 m / s, the dark matter that makes up your body, just smashed in all directions. But even at this speed dark matter particles will remain tied to the Earth, because their speed will not be enough to overcome the gravitational pull of the planet. Each individual particle, despite the movement in random directions, suddenly goes into an elliptical orbit with the Earth's center in one of the foci. Without the electromagnetic force, which prevents the passage of dark matter through the ground, it just flies until it returns to its original position: the journey takes about 88 minutes.
Remarkably, the particles of dark matter, that once you have made up, do not lose energy as it passes through the Earth. Since no forces other than gravity, they do not interfere, they will remain on indefinitely orbit, soaring above the earth's surface and back to the starting position, where was your body. You will never restore the shape of your body of these dark matter particles, instead, each particle will always pass through the point at which it was your body.
As the Earth, sun, galaxies and everything else are also subject to the laws of gravity, but the tidal forces eventually lead to the fact that dark matter behaves differently from Earth atoms. Very, very slowly tidal friction of the moon and the sun leads to the fact that the rotation of the planet slows down. Slightly extended day means that everything on the Earth's surface, the earth and the oceans to the atmosphere, will take longer to return to its original point with each rotation. But dark matter.
Instead, dark matter will drift slowly over time, moving away from its original location at least slowing down the Earth's rotation. You see, dark matter does not depend on anything other than gravity, so even at a time when the Earth's rotation varies, dark matter does not react to it. After only one year, the location where dark matter comes back, will move about half a meter and will be removed geometrically over time.
While gravitational dance of our world, the solar system and the galaxy will continue, dark matter, which once remained tied to the Earth (with you), will drift with respect to the rest of the matter, spending most of his time in the Earth's depths. But from time to time it will be returned to your original location, since no scattering forces it will not be affected. From you only the energy and momentum remain.
