The galaxies that astronomers see are indistinguishable from orbiting, probably because they produce enough gravitational force to prevent this.
But that raises the issue. Astronomers can detect the apparent amount of gravity in the galaxy and, when all is added, there is not enough space for the required gravitational force. So there has to be something that creates this energy.
Another theory is that gravity is powerful in the galaxy scale and therefore naturally provides extra strength to bind galaxies.
Also, galaxies have to be filled with things that astronomers cannot see, so-called dark matter. To make numbers work, these objects need to calculate about 80 percent of the mass of galaxies so there should be plenty around. So where is it?
Physicists have been trying experiments for a variety of machines and more than one team claims to have found evidence that black matter fills our solar system in greater quantities than most experts expect. If they are right, the Earth and everything in it is plowing a dense sea of black matter at this time.
We know that till now nothing has happened to our bodies, so it is safe to say that it does not cause bad effects on our health. So while billions of dark matter have to pass through us every second, many pass through without hindrance. Over and over again, however, sometimes it will collide with the nucleus in our body.

How Many Times Does A Dark Matter Particle Pass Through us?
Scientists calculate how many times a nuclei in the medium-sized flesh mass should collide with the particles of dark matter. On an average, they say 70 kg of meat is made up of oxygen, hydrogen, carbon and nitrogen. Dark matter is more likely to collide with oxygen and hydrogen nuclei in the body and considering the most common ideas about black matter, this can happen up to 30 times a year.
But if the latest test results are correct and black interactions are more common than expected, the human black collision rate will be much higher. Scientists estimate that there must be some 100,000 collisions per year per person in the world.
Effects of Dark Matter Passing Through Us
Effects would depend on the strength and movement of the nucleus after it struck and what kind of damage it might do to nearby muscles.
It should definitely represent a small risk to the individual, but what are the implications for society as a whole? That would be an exciting next step for a biologist who has a limited amount of time left over.
