GENEVA (AP) -- Ohio State says nine of its professors are involved in what's being described as the biggest physics experiment ever.
The university says its experts are taking part in the three largest tests with a massive particle collider to recreate the conditions from right after the "big bang." That's the name for the massive explosion that scientists believe created the universe.
The collider fired two beams of protons in opposite directions today around a 17-mile ring buried under the border of Switzerland and France. The beams were fired about five hours apart, but eventually they'll go at the same time in hopes of smashing them together.
The experiments could help unravel some of the deepest mysteries of the universe.
