Call it space radio signal; is it the panacea of the missing matter?Scientists are trying to unveil the missing matter of the universe which is called dark matter and occupies 25% of the universe 02/26/2016
Scientists can now find the missing matter of the universe for the first time. This is possible as scientists have managed to detect the orientation of a space signal from 5 billion light years.
Astronomers have worked round the clock for almost a decade now trying to unravel the identity of certain kind of signal. They are referred as short radio pulses or spontaneous radio bursts that persist for just a few milliseconds. Nevertheless, they emit much more energy that would otherwise take the sun about 10,000 years to give out.
So far 18 types of signals have been established. Their transient nature had previously caused all the scientists only to know that such signals exist with no more details about them.
Concerted efforts by a team of researchers have now born fruits because the exact location giving out radio burst can be calculated. The team is majorly composed of researchers from Subaru telescope based in Hawaii and CSIRO based in Australia.
The most recent signal was identified on April, 18th 2015 and named FRB150418. The Journal Nature dated today 25th February 2016 contained a publication of this research.
Scientific findings pinpoint that such bursts originate from huge distances far away. The discovery of such signal comes with another unexpected advantage; locating the missing matter of the universe.
It is extremely difficult to account for the gravity just by mere observation. According to astronomers, only dark energy and dark matter can account for this. Dark energy occupies about 70% of the universe, while dark matter make up 25%. The remaining 5% is the ordinary matter and it includes everything that we see.
An observation of the ordinary matter as seen from all the galaxies, nebulas, stars and planets gives us about half of the expected content. Therefore, this model becomes insufficient. However, the team used FRB150418 and got amazing results. As a matter of fact, they were able to trace this missing matter. The signals happened at different frequencies and scientists used such delays in frequencies to compute the actual material the signal had passed through while on its journey lasting for about 6 billion light years.
