very hot at this early time is something for which the evidence is very strong and by pushing our current understanding of physics farther and farther back, we’re going to understand more and more of it. so, it’s a real adventure and that piece of it we really do have a program to study. the smashing together of particles in laboratory experiments really is creating conditions that were something like what was present back then at the time of the big bang, and will help us understand the universe on the big scale. so, this is very interesting idea that by looking on the very smallest scale, the smallest, tiniest
