eldavojohn writes "Scientists at Fermilab have decided that it's high time they build a 'holometer' to test the smoothness of space-time. Theoretical physicists like Stephen Hawking have proposed that space-time is not smooth but it's been a lot of math and no actual data. The Fermilab team plans to build two relatively small devices that act as 'holographic interferometers' to measure the shaking or vibration in split beams of light traveling through a vacuum. If the team finds the shaking in their measurements and records them, the theory of a holographic universe will have some evidence of non-smoothness in space-time and perhaps a foothold in bringing light to the heavily debated theoretical physics."
