🌎 The mysterious "cold spot" in the cosmic microwave background is a vast region of space cooler than its surroundings.

This cold spot is one of the largest anomalies detected in the afterglow of the Big Bang, challenging current models of cosmic structure. ✨ #universe⚡#cosmology⚡#supervoid 👉subscribe Interesting Planet 👉more Channels
