The Milky Way is the galaxy in which the Earth and our entire solar system are located. Our knowledge of the structure of space and technical capabilities are quite limited, but it is possible to conduct experiments that sometimes violate existing ideas and hypotheses.
Studying space from Earth is not the easiest thing. Large distances are “not visible” due to the presence of various artifacts in space: dust, asteroid remains and a variety of objects. Studying space beyond the boundaries of the galaxy is even more difficult.
Therefore, standard logic is used – launch a probe with equipment into space and approach the objects being studied. Thanks to this approach, an interesting phenomenon was discovered.
Until relatively recently, it was believed that it must be dark outside the Milky Way. Visible light simply has nowhere physically to be emitted from. But, as it turned out, this hypothesis was not entirely correct. The launched New Horizons probe discovered that outside the Milky Way it is actually bright. The probe, in fact, accomplished the task that was stated above – it brought the study instruments closer to the point being studied.
Scientists took a series of images using equipment installed on the probe. All known light sources were then removed from the images. But after this action it turned out that it was still light there. Essentially, eliminating obvious light sources did not make the space completely dark. Where it was expected to see only pitch darkness, light was found.
The sources of this light are currently being debated. Two relatively simple versions are easy to imagine. These could be either objects that could not be recorded and which simply no one knows about (which is strange, since the detail here is quite high), or dust in space that reflects light rays. The impact of dust on the process has not been taken so seriously until now.
But more extravagant versions are also possible. Among them, for example, is the version about dark matter. This substance still remains little explored and balances somewhere between “it does not exist” and “yes it exists.” The cosmic void here is an excellent example of where such an object exists. Technically, it may turn out that dark matter is still capable of interacting with light in one form or another.
Then it turns out that outside the Milky Way they found a real treasure trove containing a lot of useful material for study.
Dark matter cannot be seen. That’s the catch. It does not interact with visible light. But at the same time, according to the theory, visible matter affects space-time and is capable of distorting it like ordinary matter itself.
If a large amount of this dark matter is concentrated outside the galaxy, then it can be assumed that it distorts space quite noticeably and this leads to various interesting phenomena such as gravitational lensing. In this case, light does not directly interact with matter itself, but experiences the result of space distortion. This could be the reason why large amounts of light are detected outside the Milky Way.
Everyone has seen the reflectors, right? The design is quite simple. A system of reflective surfaces, oriented in the correct way, returns the beam back to the observer. It may well be that light from outside the galaxy is also being returned to the equipment on the probe by warping space in a suitable manner.
Whether this is true or not is difficult to say now. But the discovery of such a phenomenon will likely become one of the most powerful confirmations of the real existence of dark matter.
Dark matter the invicible
The presence of dark matter was suggested more than a century ago. Dark matter is invisible matter and distorts the movement of ordinary, visible matter.
All these distortions, which are heatedly discussed, such as space and time, are actually the result of the interaction of dark matter with ordinary matter.
In addition, dark matter affects light. The fact that light moves at a certain speed is also the work of dark matter. And dualism too.
In general, there is much more dark matter than ordinary matter. Those who want to see will see, but lovers of space and time will not be able to see dark matter. They don’t have time.
Space is not only width, length and height, but space also has depth. Dark matter merges with normal matter, it’s kind of parallel, right here. Therefore, space still has a degree or even degrees. And time. This is the flow of matter. Determined by Ohm’s or Bernoulli’s formula.
