A Polarizing Discovery About the Big Bang!

The video explains how polarization affects light reflection and its significance in understanding the early universe. It describes how light interacted with the plasma in the early universe and how measuring the polarization of cosmic background radiation can provide insights into the Big Bang. The video also highlights the role of gravitational waves in creating polarization patterns and their importance in confirming gravity as a quantum mechanical phenomenon, allowing us to look further back into the universe's history.

What is the primary reason polarized sunglasses can reduce glare from surfaces like lakes or windshields?

• They reflect all light.

• They absorb all light.

• They enhance brightness.

• They block horizontally polarized light.

How did light behave in the hot plasma of the early universe before it became transparent?

• It bounced off electrons frequently.

• It was absorbed completely.

• It traveled in straight lines.

• It was unaffected by the plasma.

What can the polarization of cosmic background radiation tell us about?

• The future of the universe.

• The Big Bang.

• The color of stars.

• The speed of light.

What phenomenon is responsible for creating polarizations at 45° angles in the early universe?

• Cosmic rays.

• Solar winds.

• Gravitational waves.

• Magnetic fields.
