Is the universe's oldest light secretly aligned with our own?
In short: The cosmic microwave background is the oldest light in existence, yet it contains a strange anomaly. This video explores the 'Axis of Evil'—a mysterious alignment in the universe's structure that challenges our current understanding of cosmology.
The cosmic microwave background (CMB) is the afterglow of the Big Bang. According to the standard model of cosmology, this radiation should be distributed uniformly across the sky. However, observations have revealed a strange, large-scale alignment in the temperature fluctuations of the CMB, colloquially known as the 'Axis of Evil.'
This phenomenon is significant because it suggests that the universe might not be as isotropic as we once thought. While scientists are still investigating whether this is a result of complex cosmic physics or a potential systematic error in our instruments, it remains one of the most intriguing unsolved mysteries in modern astrophysics.
