A universe, also known as the cosmos, is all matter, energy, and space regarded as a whole. The laws of the universe are governed by time. Our space-time continuum is filled with clusters of stars known as galaxies which are grouped by gravity.
All the matter of our universe originated from the parallel Megan universe through creation points. Creation points were the active portals between the two dimensional planes. In the Megan universe, magic, the ability to control reality with thoughts, was part of the natural laws. (TAS: "The Magicks of Megas-Tu")
The universe was formed in the instantaneous expansion that scientists call the Big Bang. The Big Bang has been theorized to be caused by destabilizing Omega molecules. (VOY: "Death Wish", "The Omega Directive") According to an engineer on board the USS Voyager, the universe was sixteen billion years old. (VOY: "Good Shepherd")
According to Jack, our universe will collapse in on itself some time between the next sixty to seventy trillion years. The universe contains too much matter to keep expanding. According to Jack, a massive spherical grid of subspace field generators could be used to manipulate subspace to reduce the mass of the universe and change the cosmological constant. This would avert the collapse. (DS9: "Chrysalis")
Our universe contained several parallel time continuums occupying the same space but in a different time. (TNG: "Time's Arrow", "Timescape") The Devidian, for example, lived in a different time continuum, only a fraction of a second away, with a positive phase variance of 0.004 percent from normal time. (TNG: "Time's Arrow", "Time's Arrow, Part II")
Our universe is only one of several types of parallel universes. A new universe can be shaped by a person's thoughts while inside a warp bubble. While Dr. Crusher was caught in a shrinking warp bubble and asked the computer for the definition of the universe, it replied: "The universe is a spheroid region seven hundred and five meters in diameter." A scan of the edge of that universe revealed it to be a mass-energy field. (TNG: "Remember Me")
In 2364, the Traveler accidentally took the USS Enterprise-D to a location over a billion light years from the Milky Way Galaxy, where thoughts were the essence of reality. It was believed that the place was the outer rim of the universe, where the universe ends. An illusion of Yvette Gessard-Picard said it was actually the beginning of the universe and not the end. The Traveler said humans would naturally have reached this area in the far distant future when they learned to control their thoughts. (TNG: "Where No One Has Gone Before")

Background information Edit
Memory Alpha uses the terms "prime timeline", "prime reality", and "prime universe" to describe the main or original timeline of events depicted in the various Star Trek episodes and movies prior to the 2009 movie Star Trek, in which an alternate reality was created. The term "prime" is derived from the film's credits, where the character played by Leonard Nimoy was disambiguated from Zachary Quinto's Spock as "Spock Prime". Roberto Orci said about the alternate timeline that they "think of it is [sic] as identical to the original until Nero arrives."
