Circular Reasoning?

What effect causes the temperature of celestial rings to appear warmer or cooler?

• Cosmic inflation

• Doppler effect

• Quantum fluctuations

• Gravitational lensing

What analogy is used to describe the formation of concentric rings in the sky?

• Leaves falling from a tree

• A stone skipping across a pond

• Raindrops hitting the same spot

• Waves crashing on a beach

What was the initial reaction to the first observations of these temperature variations?

• They showed some indications but were not convincing

• They were dismissed as errors

• They were immediately accepted

• They were considered groundbreaking

What method is used to test if the observed rings are due to random fluctuations?

• Making a 'random sky'

• Analyzing historical data

• Creating a simulated universe

• Using a telescope array

What is the controversy in defining a 'random sky'?

• It requires complex calculations

• It is based on outdated models

• It involves using unverified data

• It assumes certain temperature variations
