It is estimated that the past of the universe was black, but after a few hundred million years, the primitive suns brought light to the Universe. But the reason behind the appearance of those, and consequent illumination of the cosmos, has always been the subject of debate among Astronomers, but everything may be about to change due to a new theory that justifies what allowed this mist to disappear giving way to light.
The group of researchers from the University of Iowa and the Harvard-Smithsonian Center for Astrophysics elaborated this theory after observing an unusual galaxy about 600 million light-years away, the galaxy Tol 1247-232, which is one of three galaxies that emits frequencies of ultra violet light in a phenomenon known as the Lyman series.
The Lyman series radiation has the characteristic of containing the correct energy level to expel the electron of hydrogen. Dense clouds of dust and gas often interfere with the spectrum of UV radiation, making it trickier for us to detect here on planet Earth.
In order for this light to reach us, there must be something different with this galaxy when compared to others, and a throbbing light in it may have given us the clue we long for. Since the stars do not exhibit constant variations of brightness, as we can observe in our Sun.
Apparently, according to x-ray analysis, it is highly probable that a black hole is present in the galaxy in question, and what astronomers assume is that the black hole is cleaning the surroundings, making way for light, and because of that we see the fluctuation in the light.
The only question is that theoretically black holes attract matter, and do not dispel any kind of energy that makes it possible to clean a galaxy, unless the very rotation of the black hole, may be playing a fundamental role in this matter, and then should expel some of the material, generating this observable scintillating light.
So, we now know that black holes may have played a crucial role in cleansing the cosmos, so that we can observe light at great distances.
