For all we know, the three dimensional world we see around us is really an illusion — one that’s actually in 2D. It’s a slightly unsettling idea, but it’s also one that physicists have been thinking about for some time. Unfortunately, until recently, a 2D universe wasn’t something we could verify. Now, thanks to an experiment recently launched at Fermi National Laboratory in Illinois, we might finally be able to determine how the universe stores the information we interact with everyday — and whether we’re living in a hologram.

“For thousands of years we have assumed that space is made of points and lines,” said Craig Hogan, director of Fermilab’s Center for Particle Astrophysics, in email to The Verge. But “maybe that is not right — it…
