Science Fair victor enlists Haleakala scope for project
His science project looked at time dilation and Albert Einstein’s Theory of Relativity as they relate to quasars – pretty heady stuff from the winner of the Maui science fair this year.
Steven Okada, a senior at Maui High School, did his project on “Spectral Analysis of Quasar Time Dilation,” capturing the top prize at Thursday’s 54th annual Maui Schools’ Science and Engineering Fair and a trip to the Intel International Science Fair in Phoenix from May 12 to 17.
Pausing to dummy down his project for regular folks, Okada explained that his project looked “for the effects of time dilation in galaxies that are very far away . . . the stretching out of time for objects moving relative to us.”
He was reading a study by astronomer Mike Hawkins (not theoretical physicist Stephen Hawking, as appeared in a caption in Friday’s edition) from the Royal Observatory in Edinburgh, Scotland, that there was no time dilation for light pulses from quasars even though they are expected to show the phenomenon because they are moving away from the Earth so quickly.
Time for a lesson on time dilation and quasars.
Time dilation is a component of Einstein’s Theory of Relativity. According to the PBS Nova website on the program “Einstein’s Big Idea”:
“His idea was that, theoretically, the closer we come to traveling at the speed of light (186,000 miles per second), the more time would appear to slow down for us from the perspective of someone who, in relation to us, was not moving. He called the slowing of time due to motion ‘time dilation.’ “
To illustrate the concept, the website suggested imagining a person standing on Earth holding a clock and another person with a clock in a rocket zooming past at nearly 186,000 miles per second. If the person on Earth were able to view the clock in the rocket ship, he would notice that it would appear to be moving a lot more slowly than the one on Earth. The person in the rocket would think the clock in the rocket is moving just fine while the clock on the ground would seem to be moving very fast.
Quasars are “the most luminous, powerful and energetic objects known of at this time,” according to the Universe Today website. “They seem to inhabit the centers of active young galaxies and can emit up to a thousand times the energy output of our entire galaxy.”
Quasars are believed to be powered by the buildup of material into “centralized super-massive black holes,” the website said. Light cannot escape these black holes; the escaping energy and light visible is generated by gravitational stresses and intense friction outside of the black holes.
Working with James “J.D.” Armstrong, Maui technology education and outreach specialist for the University of Hawaii’s Institute for Astronomy, Okada studied quasars, using the 2-meter Faulkes Telescope atop Haleakala.
He looked at light coming from quasars and variations in the brightness.
At the end of his research for the project, Okada said: “There is no definite answer (though) we’ve kinda found a reason.”
He said that the power spectrum looks different between wavelengths in quasars. A power spectrum can tell something about the behavior of a signal at every moment in time.
“I’m hoping that this is pointing us in the right direction,” he said.
Okada, who has the University of California-Berkeley as his main college option, was heading out Friday to preparations for the Hawaii Science Bowl, to be held today at Honolulu Community College.
Also attending the Intel science fair will be the second-place qualifier, Sarah Jenkins, a Molokai High School 10th-grader. Her project was “Artificial Nesting Structures For Hawaiian Coot Nesting Success.”
The Hawaii Academy of Sciences will help defray some of their transportation expenses.
Jenkins and Okada also will be attending the Hawaii State Science and Engineering Fair from April 7 to 9 at the Hawaii Convention Center on Oahu.
