'Space Dust' is the simple definition for incredibly small particles that reflect light on a massive scale. Space dust is considered by a minority of scientists to be the viewable definition of dark matter which is thought to be nothing but is countered by the theory that everything is something proving that nothing must be something in actual fact. This theory that thinking 'Space Dust' may be dark matter has been thought because in simple terms it cannot be viewed in any other way except from the reflection of light at a precise angle. In case you do not know what dark matter is, it has only ever been considered to have maybe been seen on one occasion in the entire universe's history, the beginning.
During the 'Big Bang' so much energy was created that a rough scientific estimate has been calculated that for seconds there was around between 10-100 gigatons of pressure exerted per square inch or perhaps even per square centimetre as where most of the energy was produced. The energy was produced by atoms basically being smashed against each other at a tremendous rate and today this has been replicated by the particle accelerator aka the large hadron collider.
During the big bang so much energy was generated that dark matter has been considered by scientists to have been able to have been viewed for only a few seconds because so much pressure is being exerted on such a small area that the dark matter atoms cannot cope with this and a reaction occurs and light is produced. How the light is produced is far too advanced to explain in simple termanology but today scientists believe that dark matter can be seen in nebulae but it would be nowhere near as powerful as when it could have been during the big bang (Scientists are not definite on this fact).
There are many theories into what dark matter can do and one of the common theories is time travel. This is basically the thought that if such an unbelievable amount of power could be generated into an incredibly small area that perhaps that area would cease to exist and that any matter that went into this area could change to a time scale of 1 second in the area is the equivalent of 10 years in normal time. The time travel theory is plausable but there is not so much hope for the ability to travel backwards in time. This theory is quite long but i will explain it.
The theory of being able to travel back in time involves believing that the entire universe has been divided into miniscule segments like the film on a camera and if it is played in consecutive order it will create a slideshow. That is the same basis of what time travel backwards is, that each fraction of an infinite of a second is recorded in the universes particles and if somehow negative particles could be genereted it would allow a person to travel backwards through each of these segments and replay a part in time. This theory has been widely discredited as it involves the belief in 'cellular memory' which has no prrof to which it can but also cannot exist but because there is no evidence it has almost been ruled out.
These are just some of the details of 'Space Dust' and if you would like more information please feel free to research it by all means necessary but this is as far as i can explain without taking many pages of information that is highly advanced.
