Radio telescope will help the world’s astronomers, physicists and scientists unravel today’s biggest cosmic mysteries

By McGill Reporter Staff

A Canadian effort to build one of the most innovative radio telescopes in the world will open the universe to a new dimension of scientific study. The Canadian Hydrogen Intensity Mapping Experiment (CHIME), is a collaboration of 50 Canadian scientists from McGill, the University of British Columbia, the University of Toronto, and the National Research Council of Canada (NRC).

On Sept. 7, The Honourable Kirsty Duncan, Minister of Science, installed the final piece of this new radio telescope, which will act as a time machine allowing scientists to create a three-dimensional map of the universe extending deep into space and time.

“CHIME is an extraordinary example showcasing Canada’s leadership in space science and engineering. The new telescope will be a destination for astronomers from around the world who will work with their Canadian counterparts to answer some of the most profound questions about space,” said Duncan. “Our government believes in providing scientists with the opportunities and tools they need to pursue the answers to questions that keep them up at night.”

An extraordinarily powerful new telescope, CHIME’s unique “half-pipe” telescope design and advanced computing power will help scientists better understand the three frontiers of modern astronomy: the history of the universe, the nature of distant stars and the detection of gravitational waves.

By measuring the composition of dark energy, scientists will better understand the shape, structure and fate of the universe. In addition, CHIME will be a key instrument to study gravitational waves, the ripples in space-time that were only recently discovered, confirming the final piece of Einstein’s theory of general relativity.

““CHIME’s unique design will enable us to tackle one of the most puzzling new areas of astrophysics today – Fast Radio Bursts,” said Astrophysicist Vicky Kaspi, Director of McGill’s Space Institute. “The origin of these bizarre extragalactic events is presently a mystery, with only two dozen reported since their discovery a decade ago. CHIME is likely to detect many of these objects every day, providing a massive treasure trove of data that will put Canada at the forefront of this research.”

The $16-million investment for CHIME was provided by the Canada Foundation for Innovation and the governments of British Columbia, Ontario, and Quebec, with additional funding from the Natural Sciences and Engineering Research Council and the Canadian Institute for Advanced Research. The telescope is located in the mountains of British Columbia’s Okanagan Valley at the NRC’s Dominion Radio Astrophysical Observatory near Penticton.

Here are some interesting facts about the CHIME telescope:

  • The CHIME telescope incorporates four 100-metre long U-shaped cylinders of metal mesh that resemble snowboard half-pipes. Its overall footprint is the size of five NHL hockey rinks.
  • CHIME collects radio waves with wavelengths between 37 and 75 centimetres, similar to the wavelength used by cell phones.
  • Most of the signals collected by CHIME come from our Milky Way galaxy, but a tiny fraction of these signals started on their way when the universe was between 6 and 11 billion years old.
  • The radio signal from the universe is very weak and extreme sensitivity is needed to detect it. The amount of energy collected by CHIME in one year is equivalent to the amount of energy gained by a paper clip falling off a desk to the floor.
  • The data rate passing through CHIME is comparable to all the data in the world’s mobile networks. There is so much data that it cannot all be saved to disk. It must first be processed and compressed by a factor of 100,000.
  • Seven quadrillion computer operations occur every second on CHIME. This rate is equivalent to every person on Earth performing one million multiplication problems every second.

One Response to New Canadian telescope will map largest volume of space ever surveyed

  1. There might be some astronomical observation of gravitational waves produced by neutron stars; although, I think, this time it is quite improbable, looking at the sheer fortuitousness of the so-called detection makes it untenable — the VIRGO run was too short (just 25 days), LIGO never found any orbiting neutron stars’ gravitational waves in the last 3 years, while there are too many neutron stars nearby to have slipped LIGO’s notice. Let me add, 6 years earlier, minuscule gravitational waves of a wide frequency range (nearly zero to around 3 KHz) were first produced and detected in my lab late in 2010 and were reported in a US patent application which now is a US patent 8521029. You can find the patent detail on the USPTO site as well as on https://www.google.com/patents/US8521029 . You can check out gravitational waves and my work on Wikipedia. Let me also add, even if I am letting out a little secret, it is impossible to register any black hole mergers, because of the sheer volume of mergers — I cannot talk more on this subject. So, let me tell you, LIGO actually never detected any black hole mergers in the past too. The least I can say is that the reported mergers were a result of the intense imagination of the LIGO folks, to say the least. And now to slip in the final secret — Speed of gravity is infinite while LIGO shows it to be equal to the speed of light in its so-called observations. That is why all the gravitational wave observations by LIGO are false.
