Living in a simulated world: Scientists explore the theory
2012 12 17

University of Washington physicists have come up with one way to test whether our universe is a giant computer simulation being run by our descendants.
It is entirely plausible, says University of Washington physics professor Martin Savage, that our universe and everything in it is one huge computer simulation being run by our descendants.
You, me, this newspaper, the room you’re sitting in — everything we think of as reality is actually being generated by vast, powerful supercomputers of the future.
If that sounds mind-blowing, Savage and his colleagues think they’ve come up with a way to test whether it’s true.
University of Washington physics professor Martin Savage, left, and physics graduate student Zohreh Davoudi published a paper on how to test if the universe is a massive computer simulation.
Their paper, "Constraints on the Universe as a Numerical Simulation," has kindled a lively international discussion about the simulation argument, which was first put forth in 2003 by University of Oxford philosophy professor Nick Bostrom.
A UW News posting explaining Savage’s paper has gotten more than 100,000 page views in a week, and ignited theories about the nature of reality and consciousness, the limits on computer networks and musings about what our future selves might be like.
Savage has been interviewed by U.S. News & World Report, The Australian and journalists in Finland, and his colleague and co-author, University of New Hampshire professor Silas Beane, has been interviewed by the BBC. UW physics graduate student Zohreh Davoudi also contributed to the paper.
"It’s sort of caught fire," Savage said.
Bostrom, the Oxford professor, first proposed the idea that we live in a computer simulation in 2003. In a 2006 article, he said there was probably no way to know for certain if it is true.
Savage — who describes his "day job" as doing numerical simulations of lattice quantum chromodynamics — said a chance discussion among colleagues sparked the idea that there was a way to test the truth of Bostrom’s theory.
And although it might deviate from the work he usually does, it was a worthy question because "there are lots of things about our universe we don’t fully understand," Savage said. "This is certainly a different scenario for how our universe works — but nonetheless, it’s quite plausible."
In the paper, the physicists propose looking for a "signature," or pattern, in our universe that also occurs in current small-scale computer simulations. One such pattern might be a limitation in the energy of cosmic rays.
Because this theory is starting to test the limits of this reporter’s scientific knowledge, we are going to rely on the words of UW News science writer Vince Stricherz, who translated the 14-page paper into laymen’s terms:
"There are signatures of resource constraints in present-day simulations that are likely to exist as well in simulations in the distant future, including the imprint of an underlying lattice if one is used to model the space-time continuum," Stricherz wrote.
If our world is a computer simulation, "the highest-energy cosmic rays would not travel along the edges of the lattice in the model but would travel diagonally, and they would not interact equally in all directions as they otherwise would be expected to do."
In other words, even supercomputers capable of creating a simulation of the universe would be hobbled by finite resources, and one way we might be able to detect those limits is to look for cosmic rays that don’t travel the way they would be expected to travel.

Microsoft is designing a “smart bra” that will monitor women’s health by tracking their heart rate, her emotional state, whether or not she is over-eating and more.
Sensors in the bra detect when the wearer is bored, stressed or discouraged and send a warning signal to the woman’s smartphone that she should caution from making bad food choices.
