Theories and models were developed based on limited data and observations, and there was much speculation and debate regarding the true nature of the universe.
For example, the Atacama Large Millimeter Array (ALMA) in Chile is a revolutionary new telescope that is able to observe the universe in unprecedented detail.
This model suggests that the universe underwent a rapid expansion in the first few moments after the Big Bang, which would have caused the tiny fluctuations in the CMB.
These measurements provided even more evidence in support of the cosmic inflation and helped to refine our understanding of the universe's initial conditions.
This discovery was made by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and confirmed a major prediction of general relativity.
