When Will the Universe Get Its First 'Black Dwarf' Star?
The Big Bang happened approximately 13.8 billion years ago, and it might have only taken 50-100 million years to form the very first stars. Ever since then, the Universe has been flooded with starlight. When enough matter mostly hydrogen and helium gas gravitates together into a single, compact object, nuclear fusion must take place inside the core, giving rise to a true star.
