Supervoids vs Colliding Universes!

The video explores the mysterious cold spot in the cosmic microwave background (CMB), discussing whether it is a statistical anomaly, the result of supervoids, or evidence of a multiverse collision. The CMB's uniformity and temperature fluctuations are explained, with a focus on the supervoid hypothesis and its challenges. Alternative explanations, including modified gravity and multiverse theories, are considered. The multiverse hypothesis suggests that bubble universes could collide, leaving temperature gradients in the CMB. Further observations are needed to determine the true nature of the cold spot.
