The universe is dark. In fact, it’s so dark that we can’t see anything at all in the night sky. There’s some light, but not enough and this strange lack of light gives us a headache. How do astronomers know about the night sky and what is causing such darkness? Astronomers have a few ways to find out about these things, one of which is by making observations in darkness itself! This blog will provide you with an overview of three approaches to understanding how to observe in darkness. If the other astronomy blogs on the site are of interest to you, please check them out!

Conclusion
Contrary to popular belief, dark matter isn’t made up of nothing at all.
In fact, it’s something that our eyes cannot see, but that’s not it’s only property. In addition to having no interaction with light, dark matter can be made up of microscopic crystal structure. If you were to put a piece of these together, they would become a very strong force, capable of squeezing the gas molecules in the center of a ball into tiny bubbles, or of pulling them apart.Dark matter doesn’t respond to the electromagnetic force like regular matter.
Rather, it’s believed to bind itself down together through gravity, like a solid rock. Scientists call this gravitational pull “tug” since it works just like a strong magnet. This means that dark matter is much heavier than we think. Estimates say that some 10 percent of the universe consists of dark matter that doesn’t emit light.There are two different kinds of dark matter particles together referred to as “axions.”
An axion is a type of unstable particle that emits x-rays when it collides with an ordinary magnet. Another kind of dark matter particle is a Baryon, which is nothing more than an ordinary hydrogen atom with a neutrally charged nucleus. astronomers don’t know what the relationship between these two types of particles is. Some theories suggest that the Baryon might be responsible for creating X-rays from exploding stars. If true, this would be very exciting to discover.Astronomers suspect that the structure of the universe consists of numerous dark matter grains.
If this is true, then the sizes of some major galaxies could be a lot larger than we expect. Some smaller galaxies, however, seem to be very small, even though they contain large amounts of matter. These objects may not be as spherical as we think, and they may have a halo around them that we can’t see.
Although there is no way to test whether these theories are true, or even to measure their accuracy, astronomers have made some very strong observations that seem to verify their accuracy. In general, astronomers estimate that the universe consists of about ten billion elementary particles, which make up dark matter.
By using powerful telescopes, they have been able to detect matter in space around other galaxies. The detection of this small but significant quantity of dark energy seems to imply that our theory of the universe is correct.
One of the major predictions of the standard model of physics is that the amount of matter must be proportional to the density of matter in the universe. If it isn’t, the predictions are false, and we must find a new way to explain the excess energy. This is why astronomers have looked for black holes. Since nearly every galaxy has at least one black hole, they have used black holes to search for dark matter. If they find it, they can confirm or rule out the standard model of physics.Another prediction of the standard model of physics is that normal matter will not emit light.
Because most of the known elements, like hydrogen, cannot be made by chemical reactions without emitting light, scientists think that it must exist in the form of dark matter. They use satellites and infrared detectors to hunt for it, and so far they have been successful in finding it. So can they confirm the existence of dark matter? Some believe so, while others doubt that it even exists at all.
Conclusion
Astronomy can tell us a lot about the nature of the universe. For instance, many astronomers have discovered that the majority of galaxies are moving through space in large amounts of velocity, which is unusual. While this is a good thing, what is meant by “a large amount of velocity” could be a variety of things, from large collisions to large explosions.Either way, it means that there is some sort of dark matter that is passing through space, and astronomers have a number of ways to detect it. In fact, one of the biggest clues to understanding how the universe works is the way that stars and other objects in the universe seem to move through it.
