Physicist honoured for work on universe’s baby photo

VANCOUVER — Astrophysi­cist Dr. Gary Hinshaw wasn’t sure what a satellite would find when it launched in 2001.

The data it discovered would lead his NASA team to create what Hinshaw describes as the universe’s baby picture.

It also set up the researcher­s for a prestigiou­s science prize awarded by a group that includes the founder of Facebook.

“You build this instrument, you test it on the ground, you make sure it’s going to survive the rigours of a rocket launch and that it’s going to deploy it when you deploy it from the rocket, and if it doesn’t, you’ve just wasted 10 years of your life, because you don’t get a second chance,” said Hinshaw, now a researcher and professor at the University of British Columbia.

The satellite, called the Wilkinson Microwave Anisotropy Probe (WMAP), did survive and spent nearly a decade measuring heat radiation left over from the big bang. Hinshaw and his team then mapped that data, giving a visual picture of the early universe. They’ve also analyzed the findings to determine that the universe is 13.7 billion years old and only five per cent is made up of the chemical elements found in the periodic table.

Hinshaw and 26 other researcher­s were honoured for their work Sunday with the Breakthrou­gh Prize in fundamenta­l physics.

Since 2012, the award has been handed out for top achievemen­ts in physics, life sciences and mathematic­s. The Breakthrou­gh Prize board includes Facebook founder Mark Zuckerberg, Anne Wojcicki, the co-founder and CEO of the genetics company 23andme, and Yuri Milner, a Russian physicist, entreprene­ur and venture capitalist.

Receiving the award is humbling, said Hinshaw, who travelled to Palo Alto, Calif., for the star-studded ceremony, hosted by actor Morgan Freeman.

The WMAP work has been a once-in-a-lifetime experience and a labour of love, Hinshaw said, noting that he and his colleagues published about 13 papers over a span of five months on the first year’s results.

He described his 15 to 20 years working on the project as intense and “brutally rewarding.”

The most amazing part is that the map included so many profound answers, Hinshaw said.

“Nature could have been much less kind and not left a fossil like this behind. And we wouldn’t have the ability to answer these questions yet today.”

The work also created new questions for researcher­s looking at the origin and compositio­n of the universe.
