According to my measly understanding of the universe, when particles hit one another, some of their kinetic energy is transformed into heat. But when we heat particles (for instance, putting a bucket of water on a stove) we can see they gain kinetic energy (the water-particles start fidgeting about until they turn to gas, which moves freely).
So, heat transforms to movement, movement transforms to heat. Cool. Which came first and started the chain?
I tried to solve it by imagining a dude standing inside a bubble, watching the big-bang (he has a very special bubble, called Mr. Bubble). When the universe went all BOOOOM, at that first time-unit, I tried thinking about what would happen to the bubble. Having only a bit of world experience and a bit of logic, my first thought was "it'd heat up". But I hardly think that qualifies as an actual answer.
Am I getting it completely wrong? Will Mr. Bubble be blown back but remain at present temperature? Is movement a form of heat? Or are all kinds of energy essentially the same thing, with different manifestations? Or maybe Mr. Bubble was the culprit all along?
