Exploring mysteries of space: Unique 3D space telescope opens in Canada

It’s far different looking than your typical idea of a telescope, and unlike most others, has no moving parts.

The Canadian Hydrogen Intensity Mapping Experiment is known as CHIME and the last piece was symbolically added today by Canada’s Science Minister Kirsty Duncan at the location near Penticton, British Columbia.

CHIME employs a series of unique 100-metre long “half-pipe” metal mesh designs in a telescope field a little over 100 by 100 metres

The unique telescope incorporates relatively low cost technology and massive computing power in a unique design considered one of the most unique in the world.

Quoted in a press release today, Dr. Mark Halpern, University of British Columbia  says, “With the CHIME telescope we will measure the expansion history of the universe and we expect to further our understanding of the mysterious dark energy that drives that expansion ever faster. This is a fundamental part of physics that we don’t understand and it’s a deep mystery. This is about better understanding how the universe began and what lies ahead.”

The telescope will be measuring the composition of dark energy whereby scientists will better understand the shape, structure and fate of the universe. It will also 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.

The array will also study the still little understood “Fast Radio Bursts”. The origin of these bizarre extragalactic events is presently a mystery, with only two dozen reported since their discovery a decade ago.  Dr  Victoria Kaspi of McGill University says “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.”

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
  9. Radio Canada International publishes contents in five languages. The language used in the forums has to be the same as the contents we publish. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
  13. Posting any type of advertising or call to action, in any form, to Radio Canada International  forums is prohibited.
  14. All comments and other types of content are moderated before publication. Radio Canada International  reserves the right to refuse any comment for publication.
