Why are we not able to see the fraction of the mass of spiral galaxies because of its amazing gravity and small size? Well, it is possible that we cannot see these small things because our telescopes are too big and they pass over them or they are too faint to see. We know that they exist, but they are very far away and we cannot see them with the naked eye.
Why do I say this? There are many reasons why it is hard to see this fraction of the mass of spiral galaxies is in dark matter? First, they are very far away and therefore they are hidden by the brightness of the stars they contain. In addition, they are very tiny and they get swallowed up by the great ocean of space. They cannot be seen by satellites or by ground-based telescopes.
What could be so small? Are they dark? Yes, they are. And they have just enough mass to accumulate what is known as a black hole. This is a very dense region of space and it is so dense that it would literally swallow up all the matter of the solar system.
Can you see it with your naked eye? Yes, you can. It is possible to see these objects with the help of an instrument called a Very High Magnetic Field instrument (VHMT). This type of instrument can measure the mass of a spiral galaxy. The higher the magnetic field, the greater the mass of the spiral.
So, how is this done? It is done by detecting the magnetic fields that surround many of these spiral structures. A piece of the telescope, a radio, or an ultra sound gadget, such as a space probe, is used to take a look at the answer to the question; “How is the fraction of the mass of spiral galaxies determined?” Here is another way to look at it; “How is the fraction of the mass of spiral galaxies measured for pulsars?” Of course there are other ways that will be used in the future to answer this question.
One of the greatest discoveries in recent years is the discovery that our Milky Way Galaxy has a large number of magnetized bulges. The discovery came about when the European Space Agency’s Planck satellite took a close look at this magnetized bulge. And what he found is that the bulge contains about twice as much normal matter as the bulge is made up of magnetized gas. So, by measuring the percentage of normal matter that is inside a spiral structure, we can estimate the fraction of dark matter in that structure. This calculation gives us our best estimate as to how much a fraction of the mass of a spiral galaxy is made up of dark matter.
If we find that the fraction of the mass of a galaxy is indeed close to one percent, then it means that a very substantial portion of that mass is dark matter. We have no idea what it is, but this does not seem to be a problem. After all, if the majority of the mass of a spiral structure is dark matter, then most of the other stuff in the universe is as well. After all, everything that lives on Earth is made up of dark matter. Since it cannot be seen, it is assumed that it is also undetectable. But, like all the other stuff, it also eventually passes through ordinary matter and it makes up a small fraction of the total amount of matter in the universe.

To conclude, we have some interesting questions about the nature of the fraction of the mass of spiral galaxies is in dark matter. There is one possibility that it might be a result of a very compact mass, similar to the colliding with another compact mass to create a black hole. The fraction of the mass of spiral galaxies that is in dark matter may also be due to a very massive merger between two very compact regions. The merger is too small to notice for modern instruments, but it would have produced a very large quantity of radio-active gas. So, we need to look for other possibilities.
