Galaxy Is Better than Believed

Spacetime may be less like alcohol and more like drinking tequila.
Or so an intergalactic picture complete would recommend.

Physicist John Nemiroff of Mich Technical Univ. achieved this heady summary after learning the tracings of three photons of varying wavelengths that had been registered by NASA’s Fermi Gamma-ray Area Telescope in May 2009.

USA, NASA: The photons started about 7 billion dollars many decades away from World in one of three impulses from a gamma-ray rush and arrive at the revolving about telescope just one nanosecond apart, in a exclusive tie.
Gamma-ray jolts are short-lived jolts of gamma-ray photons, the most dynamic way of mild. They can come far across the galaxy, and astronomers believe many are brought on by massive celebrities failing, often immeasureable decades before the World was established.
“Gamma-ray jolts can tell us some very exciting factors about the galaxy,” Nemiroff says. In this situation, those three photons registered by the Fermi telescope recommend that spacetime may not be not as fizzy as some researchers think.
Some concepts of huge severity say that the galaxy is not sleek but foamy — created of essential models known as Planck measures that are less than a trillionth of a trillionth the size of a hydrogen atom. Planck measures are so little that there is no way to identify them, except via photons like those that create up gamma-ray jolts.
Here’s why. The wavelengths of these photons are some of the smallest ranges known to technology — so brief they should communicate with the even little Planck duration. And if they communicate, the photons should be spread — spread — on their travel through Planck length–pixelated spacetime.
In particular, they should spread differently if their wavelengths vary, just as a table tennis tennis ball and a baseball might take different routes down a extremely hillside.
You would not find the spreading over brief ranges, but across immeasureable many decades, the Planck measures should spread the mild. And three photons from the same gamma-ray rush should not have gone down through the Fermi telescope at the same time.
But they did, and that calling into query just how foamy spacetime really is. “We have proven that the galaxy is sleek across the Planck huge,” Nemiroff says. “That indicates that there is no choppiness that is noticeable. It’s a really awesome development. We’re very thrilled.”
