A Q&A with physicist William Trischuk about the Large Hadron Collider.

Did you know that only four per cent of the universe is visibly accounted for? The vast majority is what’s called dark matter and dark energy—we can observe its effects, but we don’t know what it is.

Did you know that every particle of matter has a corresponding anti-matter particle out there somewhere and that these two particles should annihilate each other? So why are we still here?

These are some of the head-scratchers that particle physicists are hoping the experimental will answer. We spoke to U of T physics professor William Trischuk, one of the scientists working at the Large Hadron Collider to find out how the ambitious project is going.
