Awake and alive today,
The universe is commonly defined as the totality of everything that exists, including all physical matter and energy, the planets, stars, galaxies, and the contents of intergalactic space, although this usage may differ with the context. The term universe may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world, or nature. Observations of earlier stages in the development of the universe, which can be seen at great distances, suggest that the universe has been governed by the same physical laws and constants throughout most of its extent and history.
The reason we are all often so insecure is because we tend compare our behind the scenes to everyone else's highlight reel.
A star can maintain its internal pressure only if it continually generates energy to replace the energy that it radiates into space. All stars spend a significant amount of their lifetime fusing hydrogen to helium. As a star has a limited amount of material in its core, it cannot rely on thermal energy to resist gravity forever and its ultimate fate depends on whether something other than thermal pressure manages to halt the unceasing crush of gravity.
