虽然感觉是个long shot， 但是还是为了科学的探索精神而感动

Get close enough to your TV screen and you’ll see pixels, small points of
data that make a seamless image if you stand back. Scientists think that the
universe’s information may be contained in the same way and that the
natural “pixel size” of space is roughly 10 trillion trillion times
smaller than an atom, a distance that physicists refer to as the Planck
scale.
“We want to find out whether space-time is a quantum system just like
matter is,” says Craig Hogan, director of Fermilab’s Center for Particle
Astrophysics and the developer of the holographic noise theory. “If we see
something, it will completely change ideas about space we’ve used for
thousands of years.”
Quantum theory suggests that it is impossible to know both the exact
location and the exact speed of subatomic particles. If space comes in 2-D
bits with limited information about the precise location of objects, then
space itself would fall under the same theory of uncertainty. The same way
that matter continues to jiggle (as quantum waves) even when cooled to
absolute zero, this digitized space should have built-in vibrations even in
its lowest energy state. | a*****y

1700年左右-1880年左右-1930年左右
有多少年？300年左右
“正经”搞也不过百年
【在 a*****y 的大作中提到】
: 物理学这么多年就折腾这个，也没弄出啥
