Professor Geraint Lewis’ activity is to look most of the way over the universe at something undetectable.
One of the world’s most capable telescopes has found a red-hot ring in space. It’s a billow of sparkling gas in a distant galaxy, 12 billion light-years away, its picture twisted into a hover by an interceding “gravitational focal point”.
Lewis is endeavouring to work out what that focal point is made of. It’s a fiendishly dubious project over incredible distances. In any case, Lewis has discovered the genuine oppression of distance is amongst Sydney and Bavaria.
Lewis has quite recently returned from Garching, which is close to Munich, where he was one of the primary Australian cosmologists to exploit their new association with the European Southern Observatory.
Nothing truly whips sitting and conversing with someone about a project, as he says
He has significantly done more, as far as getting ideas from being in Bavaria and talking with individuals than he would have over long periods of time of sending e-mails.
A year ago, the government gave Australian astronomy a major kickstart, handballing old nearby telescopes to the college division and marking us up to the ESO.
Lewis was excited
At the ESO, he sat down with Rob Ivison, who is the head of science. Ivison has a goldmine of information from another age of telescopes high in the Chilean mountains, which are demonstrating that the universe in an exceptional detail.
Lewis got his skill in “gravitational lensing”, which is the capacity to disentangle and decipher pictures of cosmic objects that have traversed the universe for billions of years.
So what’s the plan?
Together, they would like to comprehend the dark side of the universe, the dark matter the dark energy. That sort of things.
Dark matter, by definition, can’t be seen or observed. Be that as it may, until the point that we realize what it is, we can’t completely comprehend the essential powers and substances of nature that brought the universe into being and made it what it is today.
The issue is that the thing that you are attempting to do is derive the properties of something you can’t really observe.
