Researchers at Fermilab are building a "holometer" so they can disprove everything you thought you knew about the universe.
The universe-as-hologram theory is predicated on the idea that spacetime is not perfectly smooth, but becomes discrete and pixelated as you zoom in further and further, like a low-res digital image. This idea isn't novel; recent experiments in black-hole physics have offered evidence that this may be the case, and prominent physicists have proposed similar ideas. Under this theory, the universe actually exists in two dimensions and the third is an illusion produced by the intertwining of time and depth. But the false third dimension can't be perceived as such, because nothing travels faster than light, so instruments can't find its limits.
This is theoretical physics at its finest, drowning in complex mathematics but short on hard data. So Fermilab particle astrophysicist Craig Hogan and his team are building a "holometer" to magnify spacetime and see if it is indeed as noisy as the math suggests it might be at higher resolution.
I'm not gonna lie, that actually made negative sense to me, but I suspect somebody's pissed about all the 3-D movies coming out lately. "If we can just prove 3-D is an illusion, maybe we can go back to not having to wear those stupid glasses in the theater anymore!" Hey, not a bad idea -- let me know if you need any help (I'll be crawling under the aisles rubbing my face on women's legs).
Thanks to Mih0, who agrees building a holodeck would be way cooler.

Scientists Plan To 'Hack' Stephen Hawking's Brain To See What's Happening In There (Live And On Stage!)A group of scientists at Stanford claim they've created a device that will allow a glimpse into the workings of the human brain, and plan to demo the unit (stupidly named the iBrain because smart ≠ creative) on Stephen Hawking during a live presentation. Fingers crossed he doe... / Continue →
