Hogan's holometer: Testing the hypothesis of a holographic universe

MIT physicist Sam Waldman in the laser lab where the holometer is being constructed

In 2008, Fermilab particle astrophysicist Craig Hogan made waves with a mind-boggling proposition: The 3D universe in which we appear to live is no more than a hologram.

Now he is building the most precise clock of all time to directly measure whether our reality is an illusion.

The idea that spacetime may not be entirely smooth – like a digital image that becomes increasingly pixelated as you zoom in – had been previously proposed by Stephen Hawking and others. Possible evidence for this model appeared last year in the unaccountable “noise” plaguing the GEO600 experiment in Germany, which searches for gravitational waves from black holes. To Hogan, the jitteriness suggested that the experiment had stumbled upon the lower limit of the spacetime pixels’ resolution.

Black hole physics, in which space and time become compressed, provides a basis for math showing that the third dimension may not exist at all. In this two-dimensional cartoon of a universe, what we perceive as a third dimension would actually be a projection of time intertwined with depth. If this is true, the illusion can only be maintained until equipment becomes sensitive enough to find its limits.

“You can’t perceive it because nothing ever travels faster than light,” says Hogan. “This holographic view is how the universe would look if you sat on a photon.”

Not everyone agrees with this idea. Its foundation is formed with math rather than hard data, as is common in theoretical physics. And although a holographic universe would answer many questions about black hole physics and other paradoxes, it clashes with classical geometry, which demands a universe of smooth, continuous paths in space and time.

“So we want to build a machine which will be the most sensitive measurement ever made of spacetime itself,” says Hogan. “That’s the holometer.”

Recovery Act

Recovery Act gives LBNE team chance to grow

From left: Joel Sefcovic, Laura Sujan and Tracy Lundin joined the LBNE project thanks to Recovery Act funds.

A growing staff of project specialists is working behind the scenes to prepare the proposed Long-Baseline Neutrino Experiment for its upcoming review.

Thanks to funding from the American Recovery and Reinvestment Act, LBNE has expanded this project team, which is developing the design, cost and schedule for the experiment’s beamline, massive detectors and associated technology and facilities. Fermilab used part of the $9 million in ARRA funding it received for long-baseline neutrino research to fill much-needed LBNE project staff positions. ARRA funding will pay for the positions for about a year, and then the LBNE project funds will take over.

“The ARRA funds are extremely important, not only to create jobs, but also to sustain jobs,” said newly hired contractor Laura Sujan, contracted project controls specialist for conventional facilities. “The projects I’ve worked on over the past year have all come from ARRA funding, and those positions would not have been available to me had it not been for the recovery funds.”

Before coming to LBNE in September, Sujan worked on an ARRA-funded project to renew Chicago Transit Authority blue line train tracks in downtown Chicago.

LBNE’s two other most recent ARRA-funded additions are contractor Joel Sefcovic, project controls specialist for the liquid argon subproject, and Tracy Lundin, Level 2 manager for conventional facilities.

Sefcovic, who has worked on several other ARRA-funded projects at Fermilab, joined the LBNE team in September. Lundin joined in August.

Lundin, Sujan and Sefcovic are already heavily involved with LBNE and in helping the project prepare for its approaching CD-1 review.

“The best part of my job so far is getting to know more about LBNE,” Sefcovic said. “Learning about the proposed neutrino beamline from Fermilab to the Deep Underground Science and Engineering Laboratory in South Dakota is really interesting, and being able to help move the project forward and advance science is really rewarding.”
