World's Most Precise Clocks Could Reveal Universe Is a Hologram

As a rule, I’m suspicious of any news article that has the world “could” in the headline, but this is certainly interesting stuff.

existence could be coded in a finite bandwidth, like a live
ultra-high-definition 3-D video. And the third dimension we know and
love could be no more than a holographic projection of a 2-D surface.

A scientist’s $1 million experiment, now under construction in
Illinois, will attempt to test these ideas by the end of next year using
what will be two of the world’s most precise clocks.

Skeptics of a positive result abound, but their caution comes with
good reason: The smallest pieces of space, time, mass and other
properties of the universe, called Planck units, are so tiny that
verifying them by experiment may be impossible. The Planck unit of
length, for example, is 10 billion billion times smaller than the width of a proton. —Wired
