The earliest and most significant era in the history of the universe has released a flood of Gravitational waves, which are seen as tiny ripples in the fabric of space-time.At present, a new research study shows how the future detections of these ancient Gravitational waves can reveal the internal workings of a process known as reheating, which may be the origin or the main source of the “real” Big Bang.
Astrophysicists are not accurately sure about what had happened when the universe was less than a second old, but they surely know that it was something eventful.Cosmological observations have discovered that the universe is too smooth and too unvarying on the largest scales as given the standard pictures of the Big Bang and the identified age of the universe.
Therefore, cosmologists have come across a theory known as inflation. Before inflation, the universe was very small, and the temperatures and densities were steady. But when inflation happened, it sent everything flying away from everything else in a very short period, explaining why the distant regions of the universe look pretty much similar.
