The last piece of the Canadian Hydrogen Intensity Mapping Experiment super-telescope known as CHIME, was completed. The function of this telescope, is to map space to a level never reached before, will measure the composition of dark energy, the most mysterious form of energy in the universe, and which is suspected of accelerating the expansion of the universe.
This super-telescope will also help detect gravitational waves and analyze the radio wave emissions that reach our planet from the confines of space, and which until now have no plausible explanation.
The project is the result of a hard work of 7 years, and the super telescope consists of four pieces with 100 meters of length, and has no moving parts. It uses the motion of the Earth to capture instant images of the universe as its moves.
The principle behind CHIME is to detect and measure the location of hydrogen gas in deep space, which is the most common element in the universe, and thus through its detection, and thanks to the ability to work at enormous distances, can produce the 3D map of the cosmos, with the greatest level of detail that ever existed.
The function of CHIME is not to produce images to win prizes of photography or to delight the lovers of the space, but to detect the tone of the light emitted by the different structures of hydrogen, which will allow to measure how the Universe has expanded during the last billions of years, and will also allow us to better understand the expansion of it, and probably even the Dark Energy.
Since the volume of data to be acquired by the super telescope is giant, it will be necessary to compress these by a factor of about 100 000, just to be able to write to a disk, since the volume is equivalent to the data we produce in all networks at any time. CHIME also shares some components with our day-to-day mobile phones and the graphics cards of our computers.
