DRIVING through the countryside south of Hanover, it would be easy to miss the GEO600 experiment. From the outside, it doesn't look much: in the corner of a field stands an assortment of boxy temporary buildings, from which two long trenches emerge, at a right angle to each other, covered with corrugated iron. Underneath the metal sheets, however, lies a detector that stretches for 600 metres.

 

For the past seven years, this German set-up has been looking for gravitational waves - ripples in space-time thrown off by super-dense astronomical objects such as neutron stars and black holes. GEO600 has not detected any gravitational waves so far, but it might inadvertently have made the most important discovery in physics for half a century.

 

For many months, the GEO600 team-members had been scratching their heads over inexplicable noise that is plaguing their giant detector. Then, out of the blue, a researcher approached them with an explanation. In fact, he had even predicted the noise before he knew they were detecting it. According to Craig Hogan, a physicist at the Fermilab particle physics lab in Batavia, Illinois, GEO600 has stumbled upon the fundamental limit of space-time - the point where space-time stops behaving like the smooth continuum Einstein described and instead dissolves into "grains", just as a newspaper photograph dissolves into dots as you zoom in. "It looks like GEO600 is being buffeted by the microscopic quantum convulsions of space-time," says Hogan.

 

If this doesn't blow your socks off, then Hogan, who has just been appointed director of Fermilab's Center for Particle Astrophysics, has an even bigger shock in store: "If the GEO600 result is what I suspect it is, then we are all living in a giant cosmic hologram."

 

The idea that we live in a hologram probably sounds absurd, but it is a natural extension of our best understanding of black holes, and something with a pretty firm theoretical footing. It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level.

 

The holograms you find on credit cards and banknotes are etched on two-dimensional plastic films. When light bounces off them, it recreates the appearance of a 3D image. In the 1990s physicists Leonard Susskind and Nobel prizewinner Gerard 't Hooft suggested that the same principle might apply to the universe as a whole. Our everyday experience might itself be a holographic projection of physical processes that take place on a distant, 2D surface.

 

The "holographic principle" challenges our sensibilities. It seems hard to believe that you woke up, brushed your teeth and are reading this article because of something happening on the boundary of the universe. No one knows what it would mean for us if we really do live in a hologram, yet theorists have good reasons to believe that many aspects of the holographic principle are true.

What this all means is our universe could be a 3D hologram but encoded on a 2D surface, that our universe could exist on the crunched data of a black hole in another universe and that the black holes crunching data in our universe that looks 2D to us could be whole other 3D universes.

What a load of bollocks!

 

They're saying the Earth could be a hologram? then how come it's solid!?

 

The universe is formed in 3D data which is soild matter over a 2D plane.

Sorry what?

 

Holograms aren't solid though!

the universe hologram does not work that way as normal hologram but it hard to example.

 

think of cube, are eyes can see that is 3D and soild image.

 

I understood the first post, but this has kinda lost me :heh:

Read this yesterday, way over my head.

 

I don't mind the theory, who knows what benefits we can have from being in a holographic universe.

So?

 

I assumed everyone already knew we lived within one big hologram...? I mean, It's kinda obvious when I can do this...

 

*fades, crackles, turns 2-D, then blinks out of existance*

We're talking about space-time here, not just light. Part of space is matter, and matter is solid.

 

For the record, this whole thing is purely a hypothesis.
