The world's largest physics lab and everyone's favourite particle accelerator has been in the news more than once this last week.
Firstly, CERN scientist Antonio Ereditato revealed that recent large hadron collider results suggest subatomic particles may have gone FASTER than the speed of light.
Seemingly aware of the impact upon science (and the Universe) if this is a mistake, the team presented its work to scientists.
As reported by the BBC, "The speed of light is widely held to be the Universe's ultimate speed limit, and much of modern physics - as laid out in part by Albert Einstein in his theory of special relativity - depends on the idea that nothing can exceed it."
"We tried to find all possible explanations for this," said Ereditato. "We wanted to find a mistake - trivial mistakes, more complicated mistakes, or nasty effects - and we didn't."
Question 1: In light of this news, should we now dig deeper into CERN's approach to data accuracy?
Question 2: How deep into its software application development and code/data analysis should we peer?

Janus (179 kilometers, or 111 miles across) is on the far left. Pandora (81 kilometers, or 50 miles across) orbits between the A ring and the thin F ring near the middle of the image. Brightly reflective Enceladus (504 kilometers, or 313 miles across) appears above the center of the image. Saturn's second largest moon, Rhea (1,528 kilometers, or 949 miles across), is bisected by the right edge of the image. The smaller moon Mimas (396 kilometers, or 246 miles across) can be seen beyond Rhea also on the right side of the image.
