Researchers at Fermilab are building a “holometer” so they can disprove everything you thought you knew about the universe. More specifically, they are trying to either prove or disprove the somewhat mind-bending notion that the third dimension doesn’t exist at all, and that the 3-D universe we think we live in is nothing more than a hologram. To do so, they are building the most precise clock ever created.

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. In Fermilab’s largest laser lab, Hogan and company are putting together what they call a “holographic interferometer,” which – like a classic interferometer – will split laser beams and measure the difference in frequencies between the two identical beams.

But unlike conventional interferometers, the holometer will measure for noise or interference in spacetime itself. It’s actually composed of two interferometers – built one atop the other – that produce data on the amount of interference or “holographic noise.” Since they are measuring the same volume of spacetime, they should show the same amount of correlated jitter in the fabric of the universe. It will produce the first direct experimental insight into the fundamental nature of space and time, and there’s no telling what researchers delving into that data might find out about the holographic nature of the universe.

So enjoy the third dimension while you still can. Construction on the first instrument is already underway, and Hogan thinks they will begin collecting data on the very nature of spacetime itself by next year.

What do you guys think?

I always thought our world was 4D.

Ok.....whats the point? It won't change the way we act as a world. I really don't see a point in knowing this

Well it would spawn a new wave of technology like the "life 4d glasses" where an extra dimension opens up when you wear them thus increasing crime due to the fact that criminals can now see the police approaching in a new dimension thus allowing for quicker escape through an even more illusive dimensional route not visible without the glasses.

its like your a criminal with the glasses on and and you can see all the valuables in an extra dimension allowing you to easily discern which items you want to steal.

Well, we know that a red apple is red. There's no point in knowing it, but we do. Same concept.

Yes, our world is 3D.

We have the X Y and Z axis, which means three dimensions, AKA 3D.

The people trying to "prove" otherwise are just looking for a quick five minutes of glory.

Well, people used to think the world was flat, and they could rationalise that explanation as well.

*Shrug*

It's a theory, if they fail, then too bad. But I'm sure they've had more reason to test this theory other than your knowledge of the X,Y,Z axes.

I always thought our world is double D.

I once got attacked by a 2D bear.
