Scientist have discovered galaxies that formed only 600 million years after the Big Bang.
A group of international researchers, headed by doctor Hakim Atek, from the University of Switzerland made a stunning discovery that could very well revolutionize the Big Bang theory. Faint galaxies observed through Hubble Telescope gives us an insight on the early galactic formations.
With the aid of NASA’s deep space electronic telescope Hubble and a natural physical phenomenon known as gravitational lensing, scientist we’re able to discover samples from early galaxies in the known Universe. Gravitational lensing broadly refers to the distribution of matter on the distance between a source and the observer. Also, as light travels between the source and the observer it has the capacity to bend. This effect was also predicted by Einstein’s paper on the general theory of relativity.
Based on their findings, scientist theorize that some of the galaxies they discovered formed roughly 600 million years after the Big Bang. Doctor Atek and his team found and catalogues over 250 dwarf galaxies that we’re created somewhere between 600 and 900 million years after the Big Bang. Atek states that these small galaxies could have played a major role in the formation of the known Universe.
Sadly, the observed galaxies are much to dim, unsuitable to conduct extensive research. Scientists explain that it took light about 12 billion years to travel between the galaxy and the telescope. Basically, the scientists are looking back into the past, into the early years of our Universe. The faint galaxies observed through Hubble telescope could also provide a new dimension to the general theory of relativity.
Scientist consider this discovery as a major breakthrough because it is able to provide them with more data on the mysterious epoch of reionization. According to Big Bang theories, the reionization is the process in which all matter in our Universe is reionized after traversing what experts call “the dark ages”, when the Universe was enveloped in a foggy shroud and it was opaque.
Reionization is the second process in the phase transition of gas in our Universe and it roughly refers to the reionization of hydrogen gas. The second phase is name recombination and it refers to how electrons and protons rearrange themselves in order to create a neutral form of hydrogen.
Another researcher from the Lyon Space Observatory states that these newly discovered galaxies are even fainter than the ones previously discovered by Hubble.
To take a stroll through memory alley is the wildest dream of every scientist alive. Who wouldn’t jump at a change to take a look into the past and uncover its mysteries?
