The "how" is an open question, although the current theory is that the present incarnation of the universe was started at the "big bang". We have no idea if there was anything "before" the big bang, or even if the idea of "before" makes any sense.The "when" is, about 14.5 billion years ago. Again, the details are a little sketchy; we weren't around to observe the event.
Copernicus was an astronaut and Mathematician, it is during the research that he was able to get the principle idea that the earth was not at the center of the universe.

The scientific explanation that suggests the universe is expanding is based on Einstein's theory of relativity, where he found that the universe should be either expanding or contracting. It is also based on astronomers noticing the red tinge of light from nearby galaxies, meaning they were getting farther away.
The idea of "was" as past tense is meaningless at a singularity. There can be no "before" because time itself loses meaning. It's impossible to speculate about what came before the Big Bang because the idea of "before" only has meaning within the present temporal Universe, but no meaning in reference to the "event" that gave birth to the Universe.
The big idea for space and time is that the universe contains matter. Gravity and energy influence the formation of galaxies, and all matter of the universe.

We don't have any idea. In fact, the concept that the universe might have an edge is still a little controversial.
