Equipment connected to a house-sized sphere can focus 192 laser beams on a small point, generating temperatures and pressures that exist at cores of stars or giant planets.
NIF will be able to create conditions and conduct experiments never before possible on Earth, according to the laboratory.
A fusion reaction triggered by the super laser hitting hydrogen atoms will produce more energy than was required to prompt "ignition," according to NIF director Edward Moses.
"This is the long-sought goal of 'energy gain' that has been the goal of fusion researchers for more than half a century," Moses said.
Theoretical physics is cool, but this is pretty awesome. NOw then, who wants some popcorn?
