These scientifically accurate toys are based on the half-billion-year-old fossils of the Burgess Shale from the Canadian Rockies of British Columbia. The ancestors of all animal groups appeared in the greatest evolutionary explosion of all time – the Big Bang of evolution – 500 million years ago. The best view we have of these first animal communities on Earth exists in the Burgess Shale fossils first discovered on Mt. Stephen in 1886. In 1975, Dr. Desmond Collins led the first ROM expedition to the Burgess Shale. He returned for 18 seasons and discovered new Burgess Shale fossil sites and collected many thousands of unique and bizarre fossils…

The concept of a time machine typically conjures up images of an implausible plot device used in a few too many science-fiction storylines. But according to Albert Einstein’s general theory of relativity, which explains how gravity operates in the universe, real-life time travel isn’t just a vague fantasy.
Time travel to the past, however, is even less understood. Still, astrophysicist Eric W. Davis, of the EarthTech International Institute for Advanced Studies at Austin, argues that it’s possible. All you need, he says, is a wormhole, which is a theoretical passageway through space-time that is predicted by relativity.
According to scientists’ current understanding, keeping a wormhole stable enough to traverse requires large amounts of exotic matter, a substance that is still very poorly understood.
General relativity can’t account for exotic matter — according to general relativity, exotic matter can’t exist. But exotic matter does exist. That’s where quantum theory comes in. Like general relativity, quantum theory is a system for explaining the universe, kind of like a lens through which scientists observe the universe.
